1 ## Rails 3.2.0 (unreleased) ##
2
562583c @jonleighton Add ActiveRecord::Relation#uniq for toggling DISTINCT in the SQL query
jonleighton authored
3 * Add ActiveRecord::Relation#uniq for generating unique queries.
4
5 Before:
6
7 Client.select('DISTINCT name')
8
9 After:
10
11 Client.select(:name).uniq
12
13 This also allows you to revert the unqueness in a relation:
14
15 Client.select(:name).uniq.uniq(false)

69dcd45 @vjebelev AR changes to support creating ordered (asc, desc) indexes
vjebelev authored
19 * Support index sort order in sqlite, mysql and postgres adapters. *Vlad Jebelev*
20
281272a @jonleighton Convert CHANGELOGs to Markdown format.
jonleighton authored
21 * Allow the :class_name option for associations to take a symbol (:Client) in addition to
22 a string ('Client').
23
24 This is to avoid confusing newbies, and to be consistent with the fact that other options
25 like :foreign_key already allow a symbol or a string.
26
27 *Jon Leighton*
28
29 * In development mode the db:drop task also drops the test database. For symmetry with
30 the db:create task. *Dmitriy Kiriyenko*
31
32 * Added ActiveRecord::Base.store for declaring simple single-column key/value stores *DHH*
33
34 class User < ActiveRecord::Base
35 store :settings, accessors: [ :color, :homepage ]
36 end
37
38 u = User.new(color: 'black', homepage: '37signals.com')
39 u.color # Accessor stored attribute
40 u.settings[:country] = 'Denmark' # Any attribute, even if not specified with an accessor
41
42
43 * MySQL: case-insensitive uniqueness validation avoids calling LOWER when
44 the column already uses a case-insensitive collation. Fixes #561.
45
46 *Joseph Palermo*
47
48 * Transactional fixtures enlist all active database connections. You can test
49 models on different connections without disabling transactional fixtures.
50
51 *Jeremy Kemper*
52
53 * Add first_or_create, first_or_create!, first_or_initialize methods to Active Record. This is a
54 better approach over the old find_or_create_by dynamic methods because it's clearer which
55 arguments are used to find the record and which are used to create it:
56
57 User.where(:first_name => "Scarlett").first_or_create!(:last_name => "Johansson")
58
59 *Andrés Mejía*
60
61 * Fix nested attributes bug where _destroy parameter is taken into account
62 during :reject_if => :all_blank (fixes #2937)
63
64 *Aaron Christy*
65
66 ## Rails 3.1.2 (unreleased) ##
67
68 * Fix bug where building the conditions of a nested through association could potentially
69 modify the conditions of the through and/or source association. If you have experienced
70 bugs with conditions appearing in the wrong queries when using nested through associations,
71 this probably solves your problems. *GH #3271*
72
73 *Jon Leighton*
74
75 * If a record is removed from a has_many :through, all of the join records relating to that
76 record should also be removed from the through association's target.
77
78 *Jon Leighton*
79
80 * Fix adding multiple instances of the same record to a has_many :through. *GH #3425*
81
82 *Jon Leighton*
83
84 * Fix creating records in a through association with a polymorphic source type. *GH #3247*
85
86 *Jon Leighton*
87
88 ## Rails 3.1.1 (October 7, 2011) ##
89
90 * Add deprecation for the preload_associations method. Fixes #3022.
91
92 *Jon Leighton*
93
94 * Don't require a DB connection when loading a model that uses set_primary_key. GH #2807.
95
96 *Jon Leighton*
97
98 * Fix using select() with a habtm association, e.g. Person.friends.select(:name). GH #3030 and
99 \#2923.
100
101 *Hendy Tanata*
102
103 * Fix belongs_to polymorphic with custom primary key on target. GH #3104.
104
105 *Jon Leighton*
106
107 * CollectionProxy#replace should change the DB records rather than just mutating the array.
108 Fixes #3020.
109
110 *Jon Leighton*
111
112 * LRU cache in mysql and sqlite are now per-process caches.
113
114 * lib/active_record/connection_adapters/mysql_adapter.rb: LRU cache keys are per process id.
115 * lib/active_record/connection_adapters/sqlite_adapter.rb: ditto
116 *Aaron Patterson*
117
118 * Support bulk change_table in mysql2 adapter, as well as the mysql one. *Jon Leighton*
119
120 * If multiple parameters are sent representing a date, and some are blank, the
121 resulting object is nil. In previous releases those values defaulted to 1. This only affects existing but blank parameters, missing ones still raise an error. [Akira Matsuda]
122 * ActiveRecord::Base.establish_connection now takes a string that contains
123 a URI that specifies the connection configuration. For example:
124 ActiveRecord::Base.establish_connection 'postgres://localhost/foo'
125
126 * Active Record's dynamic finder will now raise the error if you passing in less number of arguments than what you call in method signature.
127
128 So if you were doing this and expecting the second argument to be nil:
129
130 User.find_by_username_and_group("sikachu")
131
132 You'll now get `ArgumentError: wrong number of arguments (1 for 2).` You'll then have to do this:
133
134 User.find_by_username_and_group("sikachu", nil)
135
136 *Prem Sichanugrist*
137
138
139 ## Rails 3.1.0 (August 30, 2011) ##
140
141 * Add a proxy_association method to association proxies, which can be called by association
142 extensions to access information about the association. This replaces proxy_owner etc with
143 proxy_association.owner.
144
145 *Jon Leighton*
146
147 * ActiveRecord::MacroReflection::AssociationReflection#build_record has a new method signature.
148
149 Before: def build_association(*options)
150 After: def build_association(*options, &block)
151
152 Users who are redefining this method to extend functionality should ensure that the block is
153 passed through to ActiveRecord::Base#new.
154
155 This change is necessary to fix https://github.com/rails/rails/issues/1842.
156
157 *Jon Leighton*
158
159 * AR#pluralize_table_names can be used to singularize/pluralize table name of an individual model:
160
161 class User < ActiveRecord::Base
162 self.pluralize_table_names = false
163 end
164
165 Previously this could only be set globally for all models through ActiveRecord::Base.pluralize_table_names. *Guillermo Iguaran*
166
167 * Add block setting of attributes to singular associations:
168
169 class User < ActiveRecord::Base
170 has_one :account
171 end
172
173 user.build_account{ |a| a.credit_limit => 100.0 }
174
175 The block is called after the instance has been initialized. *Andrew White*
176
177 * Add ActiveRecord::Base.attribute_names to return a list of attribute names. This will return an empty array if the model is abstract or table does not exists. *Prem Sichanugrist*
178
179 * CSV Fixtures are deprecated and support will be removed in Rails 3.2.0
180
181 * AR#new, AR#create, AR#create!, AR#update_attributes and AR#update_attributes! all accept a second hash as option that allows you
182 to specify which role to consider when assigning attributes. This is built on top of ActiveModel's
183 new mass assignment capabilities:
184
185 class Post < ActiveRecord::Base
186 attr_accessible :title
187 attr_accessible :title, :published_at, :as => :admin
188 end
189
190 Post.new(params[:post], :as => :admin)
191
192 assign_attributes() with similar API was also added and attributes=(params, guard) was deprecated.
193
194 Please note that this changes the method signatures for AR#new, AR#create, AR#create!, AR#update_attributes and AR#update_attributes!. If you have overwritten these methods you should update them accordingly.
195
196 *Josh Kalderimis*
197
198 * default_scope can take a block, lambda, or any other object which responds to `call` for lazy
199 evaluation:
200
201 default_scope { ... }
202 default_scope lambda { ... }
203 default_scope method(:foo)
204
205 This feature was originally implemented by Tim Morgan, but was then removed in favour of
206 defining a 'default_scope' class method, but has now been added back in by Jon Leighton.
207 The relevant lighthouse ticket is #1812.
208
209 * Default scopes are now evaluated at the latest possible moment, to avoid problems where
210 scopes would be created which would implicitly contain the default scope, which would then
211 be impossible to get rid of via Model.unscoped.
212
213 Note that this means that if you are inspecting the internal structure of an
214 ActiveRecord::Relation, it will *not* contain the default scope, though the resulting
215 query will do. You can get a relation containing the default scope by calling
216 ActiveRecord#with_default_scope, though this is not part of the public API.
217
218 *Jon Leighton*
219
220 * If you wish to merge default scopes in special ways, it is recommended to define your default
221 scope as a class method and use the standard techniques for sharing code (inheritance, mixins,
222 etc.):
223
224 class Post < ActiveRecord::Base
225 def self.default_scope
226 where(:published => true).where(:hidden => false)
227 end
228 end
229
230 *Jon Leighton*
231
232 * PostgreSQL adapter only supports PostgreSQL version 8.2 and higher.
233
234 * ConnectionManagement middleware is changed to clean up the connection pool
235 after the rack body has been flushed.
236
237 * Added an update_column method on ActiveRecord. This new method updates a given attribute on an object, skipping validations and callbacks.
238 It is recommended to use #update_attribute unless you are sure you do not want to execute any callback, including the modification of
239 the updated_at column. It should not be called on new records.
240 Example:
241
242 User.first.update_column(:name, "sebastian") # => true
243
244 *Sebastian Martinez*
245
246 * Associations with a :through option can now use *any* association as the
247 through or source association, including other associations which have a
248 :through option and has_and_belongs_to_many associations
249
250 *Jon Leighton*
251
252 * The configuration for the current database connection is now accessible via
253 ActiveRecord::Base.connection_config. *fxn*
254
255 * limits and offsets are removed from COUNT queries unless both are supplied.
256 For example:
257
258 People.limit(1).count # => 'SELECT COUNT(*) FROM people'
259 People.offset(1).count # => 'SELECT COUNT(*) FROM people'
260 People.limit(1).offset(1).count # => 'SELECT COUNT(*) FROM people LIMIT 1 OFFSET 1'
261
262 *lighthouse #6262*
263
264 * ActiveRecord::Associations::AssociationProxy has been split. There is now an Association class
265 (and subclasses) which are responsible for operating on associations, and then a separate,
266 thin wrapper called CollectionProxy, which proxies collection associations.
267
268 This prevents namespace pollution, separates concerns, and will allow further refactorings.
269
270 Singular associations (has_one, belongs_to) no longer have a proxy at all. They simply return
271 the associated record or nil. This means that you should not use undocumented methods such
272 as bob.mother.create - use bob.create_mother instead.
273
274 *Jon Leighton*
275
276 * Make has_many :through associations work correctly when you build a record and then save it. This
277 requires you to set the :inverse_of option on the source reflection on the join model, like so:
278
279 class Post < ActiveRecord::Base
280 has_many :taggings
281 has_many :tags, :through => :taggings
282 end
283
284 class Tagging < ActiveRecord::Base
285 belongs_to :post
286 belongs_to :tag, :inverse_of => :tagging # :inverse_of must be set!
287 end
288
289 class Tag < ActiveRecord::Base
290 has_many :taggings
291 has_many :posts, :through => :taggings
292 end
293
294 post = Post.first
295 tag = post.tags.build :name => "ruby"
296 tag.save # will save a Taggable linking to the post
297
298 *Jon Leighton*
299
300 * Support the :dependent option on has_many :through associations. For historical and practical
301 reasons, :delete_all is the default deletion strategy employed by association.delete(*records),
302 despite the fact that the default strategy is :nullify for regular has_many. Also, this only
303 works at all if the source reflection is a belongs_to. For other situations, you should directly
304 modify the through association.
305
306 *Jon Leighton*
307
308 * Changed the behaviour of association.destroy for has_and_belongs_to_many and has_many :through.
309 From now on, 'destroy' or 'delete' on an association will be taken to mean 'get rid of the link',
310 not (necessarily) 'get rid of the associated records'.
311
312 Previously, has_and_belongs_to_many.destroy(*records) would destroy the records themselves. It
313 would not delete any records in the join table. Now, it deletes the records in the join table.
314
315 Previously, has_many_through.destroy(*records) would destroy the records themselves, and the
316 records in the join table. [Note: This has not always been the case; previous version of Rails
317 only deleted the records themselves.] Now, it destroys only the records in the join table.
318
319 Note that this change is backwards-incompatible to an extent, but there is unfortunately no
320 way to 'deprecate' it before changing it. The change is being made in order to have
321 consistency as to the meaning of 'destroy' or 'delete' across the different types of associations.
322
323 If you wish to destroy the records themselves, you can do records.association.each(&:destroy)
324
325 *Jon Leighton*
326
327 * Add :bulk => true option to change_table to make all the schema changes defined in change_table block using a single ALTER statement. *Pratik Naik*
328
329 Example:
330
331 change_table(:users, :bulk => true) do |t|
332 t.string :company_name
333 t.change :birthdate, :datetime
334 end
335
336 This will now result in:
337
338 ALTER TABLE `users` ADD COLUMN `company_name` varchar(255), CHANGE `updated_at` `updated_at` datetime DEFAULT NULL
339
340 * Removed support for accessing attributes on a has_and_belongs_to_many join table. This has been
341 documented as deprecated behaviour since April 2006. Please use has_many :through instead.
342 *Jon Leighton*
343
344 * Added a create_association! method for has_one and belongs_to associations. *Jon Leighton*
345
346 * Migration files generated from model and constructive migration generators
347 (for example, add_name_to_users) use the reversible migration's `change`
348 method instead of the ordinary `up` and `down` methods. *Prem Sichanugrist*
349
350 * Removed support for interpolating string SQL conditions on associations. Instead, you should
351 use a proc, like so:
352
353 Before:
354
355 has_many :things, :conditions => 'foo = #{bar}'
356
357 After:
358
359 has_many :things, :conditions => proc { "foo = #{bar}" }
360
361 Inside the proc, 'self' is the object which is the owner of the association, unless you are
362 eager loading the association, in which case 'self' is the class which the association is within.
363
364 You can have any "normal" conditions inside the proc, so the following will work too:
365
366 has_many :things, :conditions => proc { ["foo = ?", bar] }
367
368 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
369 'record' to get the record being inserted or deleted. This is now passed as an argument to
370 the proc.
371
372 * Added ActiveRecord::Base#has_secure_password (via ActiveModel::SecurePassword) to encapsulate dead-simple password usage with BCrypt encryption and salting [DHH]. Example:
373
374 # Schema: User(name:string, password_digest:string, password_salt:string)
375 class User < ActiveRecord::Base
376 has_secure_password
377 end
378
379 user = User.new(:name => "david", :password => "", :password_confirmation => "nomatch")
380 user.save # => false, password required
381 user.password = "mUc3m00RsqyRe"
382 user.save # => false, confirmation doesn't match
383 user.password_confirmation = "mUc3m00RsqyRe"
384 user.save # => true
385 user.authenticate("notright") # => false
386 user.authenticate("mUc3m00RsqyRe") # => user
387 User.find_by_name("david").try(:authenticate, "notright") # => nil
388 User.find_by_name("david").try(:authenticate, "mUc3m00RsqyRe") # => user
389
390
391 * When a model is generated add_index is added by default for belongs_to or references columns
392
393 rails g model post user:belongs_to will generate the following:
394
395 class CreatePosts < ActiveRecord::Migration
396 def up
397 create_table :posts do |t|
398 t.belongs_to :user
399 t.timestamps
400 end
401
402 add_index :posts, :user_id
403 end
404
405 def down
406 drop_table :posts
407 end
408 end
409
410 *Santiago Pastorino*
411
412 * Setting the id of a belongs_to object will update the reference to the
413 object. [#2989 state:resolved]
414 * ActiveRecord::Base#dup and ActiveRecord::Base#clone semantics have changed
415 to closer match normal Ruby dup and clone semantics.
416 * Calling ActiveRecord::Base#clone will result in a shallow copy of the record,
417 including copying the frozen state. No callbacks will be called.
418 * Calling ActiveRecord::Base#dup will duplicate the record, including calling
419 after initialize hooks. Frozen state will not be copied, and all associations will be cleared. A duped record will return true for new_record?, have a nil id field, and is saveable.
420 * Migrations can be defined as reversible, meaning that the migration system
421 will figure out how to reverse your migration. To use reversible migrations, just define the "change" method. For example:
422 class MyMigration < ActiveRecord::Migration
423 def change
424 create_table(:horses) do
425 t.column :content, :text
426 t.column :remind_at, :datetime
427 end
428 end
429 end
430
431 Some things cannot be automatically reversed for you. If you know how to reverse those things, you should define 'up' and 'down' in your migration. If you define something in `change` that cannot be reversed, an IrreversibleMigration exception will be raised when going down.
432 * Migrations should use instance methods rather than class methods:
433 class FooMigration < ActiveRecord::Migration
434 def up
435 ...
436 end
437 end
438
439 *Aaron Patterson*
440
441 * has_one maintains the association with separate after_create/after_update instead
442 of a single after_save. *fxn*
443
444 * The following code:
445
446 Model.limit(10).scoping { Model.count }
447
448 now generates the following SQL:
449
450 SELECT COUNT(*) FROM models LIMIT 10
451
452 This may not return what you want. Instead, you may with to do something
453 like this:
454
455 Model.limit(10).scoping { Model.all.size }
456

460 ## Rails 3.0.7 (April 18, 2011) ##
461
462 * Destroying records via nested attributes works independent of reject_if LH #6006 *Durran Jordan*
463
464 * Delegate any? and many? to Model.scoped for consistency *Andrew White*
465
466 * Quote the ORDER BY clause in batched finds - fixes #6620 *Andrew White*
467
468 * Change exists? so records are not instantiated - fixes #6127. This prevents after_find
469 and after_initialize callbacks being triggered when checking for record existence.
470 *Andrew White*
471
472 * Fix performance bug with attribute accessors which only occurred on Ruby 1.8.7, and ensure we
473 cache type-casted values when the column returned from the db contains non-standard chars.
474 *Jon Leighton*
475
476 * Fix a performance regression introduced here 86acbf1cc050c8fa8c74a10c735e467fb6fd7df8
477 related to read_attribute method *Stian Grytøyr*
478
479
480 ## Rails 3.0.6 (April 5, 2011) ##
481
482 * Un-deprecate reorder method *Sebastian Martinez*
483
484 * Extensions are applied when calling +except+ or +only+ on relations.
485 Thanks to Iain Hecker.
486
487 * Schemas set in set_table_name are respected by the mysql adapter. LH #5322
488
489 * Fixed a bug when empty? was called on a grouped Relation that wasn't loaded.
490 LH #5829
491
492 * Reapply extensions when using except and only. Thanks Iain Hecker.
493
494 * Binary data is escaped when being inserted to SQLite3 Databases. Thanks
495 Naruse!
496
497
498 ## Rails 3.0.5 (February 26, 2011) ##
499
500 * Model.where(:column => 1).where(:column => 2) will always produce an AND
501 query.
502 *Aaron Patterson*
503
504 * Deprecated support for interpolated association conditions in the form of :conditions => 'foo = #{bar}'.
505
506 Instead, you should use a proc, like so:
507
508 Before:
509
510 has_many :things, :conditions => 'foo = #{bar}'
511
512 After:
513
514 has_many :things, :conditions => proc { "foo = #{bar}" }
515
516 Inside the proc, 'self' is the object which is the owner of the association, unless you are
517 eager loading the association, in which case 'self' is the class which the association is within.
518
519 You can have any "normal" conditions inside the proc, so the following will work too:
520
521 has_many :things, :conditions => proc { ["foo = ?", bar] }
522
523 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
524 'record' to get the record being inserted or deleted. This is now passed as an argument to
525 the proc.
526
527 *Jon Leighton*
528
529
530 ## Rails 3.0.4 (February 8, 2011) ##
531
532 * Added deprecation warning for has_and_belongs_to_many associations where the join table has
533 additional attributes other than the keys. Access to these attributes is removed in 3.1.
534 Please use has_many :through instead. *Jon Leighton*
535
536
537 ## Rails 3.0.3 (November 16, 2010) ##
538
539 * Support find by class like this: Post.where(:name => Post)
540
541
542 ## Rails 3.0.2 (November 15, 2010) ##
543
544 * Dramatic speed increase (see: http://engineering.attinteractive.com/2010/10/arel-two-point-ohhhhh-yaaaaaa/) *Aaron Patterson*
545
546 * reorder is deprecated in favor of except(:order).order(...) *Santiago Pastorino*
547
548 * except is now AR public API
549
550 Model.order('name').except(:order).order('salary')
551
552 generates:
553
554 SELECT * FROM models ORDER BY salary
555
556 *Santiago Pastorino*
557
558 * The following code:
559
560 Model.limit(10).scoping { Model.count }
561
562 now generates the following SQL:
563
564 SELECT COUNT(*) FROM models LIMIT 10
565
566 This may not return what you want. Instead, you may with to do something
567 like this:
568
569 Model.limit(10).scoping { Model.all.size }

574 ## Rails 3.0.1 (October 15, 2010) ##
575
576 * Introduce a fix for CVE-2010-3993
577
578
579 ## Rails 3.0.0 (August 29, 2010) ##
580
581 * Changed update_attribute to not run callbacks and update the record directly in the database *Neeraj Singh*
582
583 * Add scoping and unscoped as the syntax to replace the old with_scope and with_exclusive_scope *José Valim*
584
585 * New rake task, db:migrate:status, displays status of migrations #4947 *Kevin Skoglund*
586
587 * select and order for ActiveRecord now always concatenate nested calls. Use reorder if you want the original order to be overwritten *Santiago Pastorino*
588
589 * PostgreSQL: ensure the database time zone matches Ruby's time zone #4895 *Aaron Patterson*
590
591 * Fixed that ActiveRecord::Base.compute_type would swallow NoMethodError #4751 *Andrew Bloomgarden, Andrew White*
592
593 * Add index length support for MySQL. #1852 *Emili Parreno, Pratik Naik*
594
595 Example:
596
597 add_index(:accounts, :name, :name => 'by_name', :length => 10)
598 => CREATE INDEX by_name ON accounts(name(10))
599
600 add_index(:accounts, [:name, :surname], :name => 'by_name_surname', :length => {:name => 10, :surname => 15})
601 => CREATE INDEX by_name_surname ON accounts(name(10), surname(15))
602
603 * find_or_create_by_attr(value, ...) works when attr is protected. #4457 *Santiago Pastorino, Marc-André Lafortune*
604
605 * New callbacks: after_commit and after_rollback. Do expensive operations like image thumbnailing after_commit instead of after_save. #2991 *Brian Durand*
606
607 * Serialized attributes are not converted to YAML if they are any of the formats that can be serialized to XML (like Hash, Array and Strings). *José Valim*
608
609 * Destroy uses optimistic locking. If lock_version on the record you're destroying doesn't match lock_version in the database, a StaleObjectError is raised. #1966 *Curtis Hawthorne*
610
611 * PostgreSQL: drop support for old postgres driver. Use pg 0.9.0 or later. *Jeremy Kemper*
612
613 * Observers can prevent records from saving by returning false, just like before_save and friends. #4087 *Mislav Marohnić*
614
615 * Add Relation extensions. *Pratik Naik*
616
617 users = User.where(:admin => true).extending(User::AdminPowers)
618
619 latest_users = User.order('created_at DESC') do
620 def posts_count
621 Post.count(:user_id => to_a.map(&:id))
622 end
623 end
624
625 * To prefix the table names of all models in a module, define self.table_name_prefix on the module. #4032 *Andrew White*
626
627 * Silenced "SHOW FIELDS" and "SET SQL_AUTO_IS_NULL=0" statements from the MySQL driver to improve log signal to noise ration in development *DHH*
628
629 * PostgreSQLAdapter: set time_zone to UTC when Base.default_timezone == :utc so that Postgres doesn't incorrectly offset-adjust values inserted into TIMESTAMP WITH TIME ZONE columns. #3777 *Jack Christensen*
630
631 * Allow relations to be used as scope.
632
633 class Item
634 scope :red, where(:colour => 'red')
635 end
636
637 Item.red.limit(10) # Ten red items
638
639 * Rename named_scope to scope. *Pratik Naik*
640
641 * Changed ActiveRecord::Base.store_full_sti_class to be true by default reflecting the previously announced Rails 3 default *DHH*
642
643 * Add Relation#except. *Pratik Naik*
644
645 one_red_item = Item.where(:colour => 'red').limit(1)
646 all_items = one_red_item.except(:where, :limit)
647
648 * Add Relation#delete_all. *Pratik Naik*
649
650 Item.where(:colour => 'red').delete_all
651
652 * Add Model.having and Relation#having. *Pratik Naik*
653
654 Developer.group("salary").having("sum(salary) > 10000").select("salary")
655
656 * Add Relation#count. *Pratik Naik*
657
658 legends = People.where("age > 100")
659 legends.count
660 legends.count(:age, :distinct => true)
661 legends.select('id').count
662
663 * Add Model.readonly and association_collection#readonly finder method. *Pratik Naik*
664
665 Post.readonly.to_a # Load all posts in readonly mode
666 @user.items.readonly(false).to_a # Load all the user items in writable mode
667
668 * Add .lock finder method *Pratik Naik*
669
670 User.lock.where(:name => 'lifo').to_a
671
672 old_items = Item.where("age > 100")
673 old_items.lock.each {|i| .. }
674
675 * Add Model.from and association_collection#from finder methods *Pratik Naik*
676
677 user = User.scoped
678 user.select('*').from('users, items')
679
680 * Add relation.destroy_all *Pratik Naik*
681
682 old_items = Item.where("age > 100")
683 old_items.destroy_all
684
685 * Add relation.exists? *Pratik Naik*
686
687 red_items = Item.where(:colours => 'red')
688 red_items.exists?
689 red_items.exists?(1)
690
691 * Add find(ids) to relations. *Pratik Naik*
692
693 old_users = User.order("age DESC")
694 old_users.find(1)
695 old_users.find(1, 2, 3)
696
697 * Add new finder methods to association collection. *Pratik Naik*
698
699 class User < ActiveRecord::Base
700 has_many :items
701 end
702
703 user = User.first
704 user.items.where(:items => {:colour => 'red'})
705 user.items.select('items.id')
706
707 * Add relation.reload to force reloading the records. *Pratik Naik*
708
709 topics = Topic.scoped
710 topics.to_a # force load
711 topics.first # returns a cached record
712 topics.reload
713 topics.first # Fetches a new record from the database
714
715 * Rename Model.conditions and relation.conditions to .where. *Pratik Naik*
716
717 Before :
718 User.conditions(:name => 'lifo')
719 User.select('id').conditions(["age > ?", 21])
720
721 Now :
722 User.where(:name => 'lifo')
723 User.select('id').where(["age > ?", 21])
724
725 * Add Model.select/group/order/limit/joins/conditions/preload/eager_load class methods returning a lazy relation. *Pratik Naik*
726
727 Examples :
728
729 posts = Post.select('id).order('name') # Returns a lazy relation
730 posts.each {|p| puts p.id } # Fires "select id from posts order by name"
731
732 * Model.scoped now returns a relation if invoked without any arguments. *Pratik Naik*
733
734 Example :
735
736 posts = Post.scoped
737 posts.size # Fires "select count(*) from posts" and returns the count
738 posts.each {|p| puts p.name } # Fires "select * from posts" and loads post objects
739
740 * Association inverses for belongs_to, has_one, and has_many. Optimization to reduce database queries. #3533 *Murray Steele*
741
742 # post.comments sets each comment's post without needing to :include
743 class Post < ActiveRecord::Base
744 has_many :comments, :inverse_of => :post
745 end
746
747 * MySQL: add_ and change_column support positioning. #3286 *Ben Marini*
748
749 * Reset your Active Record counter caches with the reset_counter_cache class method. #1211 *Mike Breen, Gabe da Silveira*
750
751 * Remove support for SQLite 2. Please upgrade to SQLite 3+ or install the plugin from git://github.com/rails/sqlite2_adapter.git *Pratik Naik*
752
753 * PostgreSQL: XML datatype support. #1874 *Leonardo Borges*
754
755 * quoted_date converts time-like objects to ActiveRecord::Base.default_timezone before serialization. This allows you to use Time.now in find conditions and have it correctly be serialized as the current time in UTC when default_timezone == :utc. #2946 *Geoff Buesing*
756
757 * SQLite: drop support for 'dbfile' option in favor of 'database.' #2363 *Paul Hinze, Jeremy Kemper*
758
759 * Added :primary_key option to belongs_to associations. #765 *Szymon Nowak, Philip Hallstrom, Noel Rocha*
760 # employees.company_name references companies.name
761 Employee.belongs_to :company, :primary_key => 'name', :foreign_key => 'company_name'
762
763 * Implement #many? for NamedScope and AssociationCollection using #size. #1500 *Chris Kampmeier*
764
765 * Added :touch option to belongs_to associations that will touch the parent record when the current record is saved or destroyed *DHH*
766
767 * Added ActiveRecord::Base#touch to update the updated_at/on attributes (or another specified timestamp) with the current time *DHH*
768
769
770 ## 2.3.2 Final (March 15, 2009) ##
771
772 * Added ActiveRecord::Base.find_each and ActiveRecord::Base.find_in_batches for batch processing *DHH/Jamis Buck*
773
774 * Added that ActiveRecord::Base.exists? can be called with no arguments #1817 *Scott Taylor*
775
776 * Add Support for updating deeply nested models from a single form. #1202 *Eloy Duran*

778 class Book < ActiveRecord::Base
779 has_one :author
780 has_many :pages
781
782 accepts_nested_attributes_for :author, :pages
783 end
784
785 * Make after_save callbacks fire only if the record was successfully saved. #1735 *Michael Lovitt*
786
787 Previously the callbacks would fire if a before_save cancelled saving.
788
789 * Support nested transactions using database savepoints. #383 *Jonathan Viney, Hongli Lai*
790
791 * Added dynamic scopes ala dynamic finders #1648 *Yaroslav Markin*
792
793 * Fixed that ActiveRecord::Base#new_record? should return false (not nil) for existing records #1219 *Yaroslav Markin*
794
795 * I18n the word separator for error messages. Introduces the activerecord.errors.format.separator translation key. #1294 *Akira Matsuda*
796
797 * Add :having as a key to find and the relevant associations. *Emilio Tagua*
798
799 * Added default_scope to Base #1381 [Paweł Kondzior]. Example:
800
801 class Person < ActiveRecord::Base
802 default_scope :order => 'last_name, first_name'
803 end
804
805 class Company < ActiveRecord::Base
806 has_many :people
807 end
808
809 Person.all # => Person.find(:all, :order => 'last_name, first_name')
810 Company.find(1).people # => Person.find(:all, :order => 'last_name, first_name', :conditions => { :company_id => 1 })

814
815 * Ensure indices don't flip order in schema.rb #1266 *Jordi Bunster*
816
817 * Fixed that serialized strings should never be type-casted (i.e. turning "Yes" to a boolean) #857 *Andreas Korth*
818
819
820 ## 2.2.0 RC1 (October 24th, 2008) ##
821
822 * Skip collection ids reader optimization if using :finder_sql *Jeremy Kemper*
823
824 * Add Model#delete instance method, similar to Model.delete class method. #1086 *Hongli Lai (Phusion)*
825
826 * MySQL: cope with quirky default values for not-null text columns. #1043 *Frederick Cheung*
827
828 * Multiparameter attributes skip time zone conversion for time-only columns [#1030 state:resolved] *Geoff Buesing*
829
830 * Base.skip_time_zone_conversion_for_attributes uses class_inheritable_accessor, so that subclasses don't overwrite Base [#346 state:resolved] *Emilio Tagua*
831
832 * Added find_last_by dynamic finder #762 *Emilio Tagua*
833
834 * Internal API: configurable association options and build_association method for reflections so plugins may extend and override. #985 *Hongli Lai (Phusion)*
835
836 * Changed benchmarks to be reported in milliseconds *David Heinemeier Hansson*
837
838 * Connection pooling. #936 *Nick Sieger*
839
840 * Merge scoped :joins together instead of overwriting them. May expose scoping bugs in your code! #501 *Andrew White*
841
842 * before_save, before_validation and before_destroy callbacks that return false will now ROLLBACK the transaction. Previously this would have been committed before the processing was aborted. #891 *Xavier Noria*
843
844 * Transactional migrations for databases which support them. #834 *divoxx, Adam Wiggins, Tarmo Tänav*
845
846 * Set config.active_record.timestamped_migrations = false to have migrations with numeric prefix instead of UTC timestamp. #446. *Andrew Stone, Nik Wakelin*
847
848 * change_column_default preserves the not-null constraint. #617 *Tarmo Tänav*
849
850 * Fixed that create database statements would always include "DEFAULT NULL" (Nick Sieger) *#334*
851
852 * Add :tokenizer option to validates_length_of to specify how to split up the attribute string. #507. [David Lowenfels] Example :
853
854 \# Ensure essay contains at least 100 words.
855 validates_length_of :essay, :minimum => 100, :too_short => "Your essay must be at least %d words."), :tokenizer => lambda {|str| str.scan(/\w+/) }
856
857 * Allow conditions on multiple tables to be specified using hash. [Pratik Naik]. Example:
858
859 User.all :joins => :items, :conditions => { :age => 10, :items => { :color => 'black' } }
860 Item.first :conditions => { :items => { :color => 'red' } }
861
862 * Always treat integer :limit as byte length. #420 *Tarmo Tänav*

865
866 * Fix column collision with named_scope and :joins. #46 *Duncan Beevers, Mark Catley*
867
868 * db:migrate:down and :up update schema_migrations. #369 *Michael Raidel, RaceCondition*
869
870 * PostgreSQL: support :conditions => [':foo::integer', { :foo => 1 }] without treating the ::integer typecast as a bind variable. *Tarmo Tänav*
871
872 * MySQL: rename_column preserves column defaults. #466 *Diego Algorta*
873
874 * Add :from option to calculations. #397 *Ben Munat*
875
876 * Add :validate option to associations to enable/disable the automatic validation of associated models. Resolves #301. *Jan De Poorter*
877
878 * PostgreSQL: use 'INSERT ... RETURNING id' for 8.2 and later. *Jeremy Kemper*
879
880 * Added SQL escaping for :limit and :offset in MySQL *Jonathan Wiess*
881
882
883 ## 2.1.0 (May 31st, 2008) ##
884
885 * Add ActiveRecord::Base.sti_name that checks ActiveRecord::Base#store_full_sti_class? and returns either the full or demodulized name. *Rick Olson*
886
887 * Add first/last methods to associations/named_scope. Resolved #226. *Ryan Bates*
888
889 * Added SQL escaping for :limit and :offset #288 *Aaron Bedra, Steven Bristol, Jonathan Wiess*
890
891 * Added first/last methods to associations/named_scope. Resolved #226. *Ryan Bates*

894
895 * Added protection against duplicate migration names (Aslak Hellesøy) *#112*
896
897 * Base#instantiate_time_object: eliminate check for Time.zone, since we can assume this is set if time_zone_aware_attributes is set to true *Geoff Buesing*
898
899 * Time zone aware attribute methods use Time.zone.parse instead of #to_time for String arguments, so that offset information in String is respected. Resolves #105. *Scott Fleckenstein, Geoff Buesing*
900
901 * Added change_table for migrations (Jeff Dean) [#71]. Example:
902
903 change_table :videos do |t|
904 t.timestamps # adds created_at, updated_at
905 t.belongs_to :goat # adds goat_id integer
906 t.string :name, :email, :limit => 20 # adds name and email both with a 20 char limit
907 t.remove :name, :email # removes the name and email columns
908 end
909

913
914 * Fixed that pessimistic locking you reference the quoted table name (Josh Susser) *#67*
915
916 * Fixed that change_column should be able to use :null => true on a field that formerly had false [Nate Wiger] *#26*
917
918 * Added that the MySQL adapter should map integer to either smallint, int, or bigint depending on the :limit just like PostgreSQL *David Heinemeier Hansson*
919
920 * Change validates_uniqueness_of :case_sensitive option default back to true (from [9160]). Love your database columns, don't LOWER them. *Rick Olson*

923
924 * ActiveRecord::Base#sum defaults to 0 if no rows are returned. Closes #11550 *Kamal Fariz Mahyuddin*
925
926 * Ensure that respond_to? considers dynamic finder methods. Closes #11538. *James Mead*
927
928 * Ensure that save on parent object fails for invalid has_one association. Closes #10518. *Pratik Naik*
929
930 * Remove duplicate code from associations. *Pratik Naik*
931
932 * Refactor HasManyThroughAssociation to inherit from HasManyAssociation. Association callbacks and <association>_ids= now work with hm:t. #11516 *Ruy Asan*
933
934 * Ensure HABTM#create and HABTM#build do not load entire association. *Pratik Naik*
935
936 * Improve documentation. *Xavier Noria, Jack Danger Canty, leethal*
937
938 * Tweak ActiveRecord::Base#to_json to include a root value in the returned hash: {"post": {"title": ...}} *Rick Olson*
939
940 Post.find(1).to_json # => {"title": ...}
941 config.active_record.include_root_in_json = true
942 Post.find(1).to_json # => {"post": {"title": ...}}
943
944 * Add efficient #include? to AssociationCollection (for has_many/has_many :through/habtm). *stopdropandrew*
945
946 * PostgreSQL: create_ and drop_database support. #9042 *ez, pedz, Nick Sieger*
947
948 * Ensure that validates_uniqueness_of works with with_scope. Closes #9235. *Nik Wakelin, cavalle*
949
950 * Partial updates include only unsaved attributes. Off by default; set YourClass.partial_updates = true to enable. *Jeremy Kemper*
951
952 * Removing unnecessary uses_tzinfo helper from tests, given that TZInfo is now bundled *Geoff Buesing*
953
954 * Fixed that validates_size_of :within works in associations #11295, #10019 *cavalle*
955
956 * Track changes to unsaved attributes. *Jeremy Kemper*
957
958 * Switched to UTC-timebased version numbers for migrations and the schema. This will as good as eliminate the problem of multiple migrations getting the same version assigned in different branches. Also added rake db:migrate:up/down to apply individual migrations that may need to be run when you merge branches #11458 *John Barnette*
959
960 * Fixed that has_many :through would ignore the hash conditions #11447 *Emilio Tagua*
961
962 * Fix issue where the :uniq option of a has_many :through association is ignored when find(:all) is called. Closes #9407 *cavalle*
963
964 * Fix duplicate table alias error when including an association with a has_many :through association on the same join table. Closes #7310 *cavalle*
965
966 * More efficient association preloading code that compacts a through_records array in a central location. Closes #11427 *Jack Danger Canty*
967
968 * Improve documentation. *Ryan Bigg, Jan De Poorter, Cheah Chu Yeow, Xavier Shay, Jack Danger Canty, Emilio Tagua, Xavier Noria, Sunny Ripert*
969
970 * Fixed that ActiveRecord#Base.find_or_create/initialize would not honor attr_protected/accessible when used with a hash #11422 *Emilio Tagua*
971
972 * Added ActiveRecord#Base.all/first/last as aliases for find(:all/:first/:last) #11413 *nkallen, Chris O'Sullivan*
973
974 * Merge the has_finder gem, renamed as 'named_scope'. #11404 *nkallen*

1249 belongs_to :article, :counter_cache => :comments_count
1250 end
1251
1252 class Article < ActiveRecord::Base

1272 * Added ActiveRecord::Base#to_json/from_json *David Heinemeier Hansson, Cheah Chu Yeow*
1273
1274 * Added ActiveRecord::Base#from_xml [David Heinemeier Hansson]. Example:

1277 Person.new.from_xml(xml).name # => "David"
1278
1279 * Define dynamic finders as real methods after first usage. *bscofield*

1291 * Extract Firebird, FrontBase, and OpenBase adapters into gems. #9508, #9509, #9510 *Jeremy Kemper*
1292

1319 * Don't clobber includes passed to has_many.count *Jack Danger Canty*
1320
1321 * Make sure has_many uses :include when counting *Jack Danger Canty*
1322
1323 * Change the implementation of ActiveRecord's attribute reader and writer methods *Michael Koziarski*
1324 - Generate Reader and Writer methods which cache attribute values in hashes. This is to avoid repeatedly parsing the same date or integer columns. - Change exception raised when users use find with :select then try to access a skipped column. Plugins could override missing_attribute() to lazily load the columns. - Move method definition to the class, instead of the instance - Always generate the readers, writers and predicate methods.
1325 * Perform a deep #dup on query cache results so that modifying activerecord attributes does not modify the cached attributes. *Rick Olson*

1333
1334 validates_presence_of :identity_url, :if => using_open_id?
1335 validates_presence_of :username, :unless => using_open_id?
1336 validates_presence_of :password, :unless => using_open_id?

1343
1344 * Change belongs_to so that the foreign_key assumption is taken from the association name, not the class name. Closes #8992 *Josh Susser*
1345
1346 OLD
1347 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is user_id
1348
1349 NEW
1350 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is visitor_id
1351
1352 * Remove spurious tests from deprecated_associations_test, most of these aren't deprecated, and are duplicated in associations_test. Closes #8987 *Pratik Naik*
1353
1354 * Make create! on a has_many :through association return the association object. Not the collection. Closes #8786 *Pratik Naik*

1389
1390 * Raise an exception if both attr_protected and attr_accessible are declared. #8507 *stellsmi*
1391
1392 * SQLite, MySQL, PostgreSQL, Oracle: quote column names in column migration SQL statements. #8466 *marclove, lorenjohnson*
1393
1394 * Allow nil serialized attributes with a set class constraint. #7293 *sandofsky*
1395
1396 * Oracle: support binary fixtures. #7987 *Michael Schoen*
1397
1398 * Fixtures: pull fixture insertion into the database adapters. #7987 *Michael Schoen*

This way you can provide custom adapters as plugins or gems without modifying Rails. *Jeremy Kemper*
1415
1416 * Ensure that associations with :dependent => :delete_all respect :conditions option. Closes #8034 *Jack Danger Canty, Josh Peek, Rick Olson*
1417
1418 * belongs_to assignment creates a new proxy rather than modifying its target in-place. #8412 *mmangino@elevatedrails.com*

1422 * Document deep eager includes. #6267 *Josh Susser, Dan Manges*
1423
1424 * Document warning that associations names shouldn't be reserved words. #4378 *murphy@cYcnus.de, Josh Susser*
1425
1426 * Sanitize Base#inspect. #8392, #8623 *Nik Wakelin, jnoon*
1427
1428 * Replace the transaction {|transaction|..} semantics with a new Exception ActiveRecord::Rollback. *Michael Koziarski*
1429
1430 * Oracle: extract column length for CHAR also. #7866 *ymendel*
1431
1432 * Document :allow_nil option for validates_acceptance_of since it defaults to true. *tzaharia*
1433
1434 * Update documentation for :dependent declaration so that it explicitly uses the non-deprecated API. *Jack Danger Canty*
1435
1436 * Add documentation caveat about when to use count_by_sql. *fearoffish*
1437
1438 * Enhance documentation for increment_counter and decrement_counter. *fearoffish*
1439
1440 * Provide brief introduction to what optimistic locking is. *fearoffish*
1441
1442 * Add documentation for :encoding option to mysql adapter. *marclove*
1443
1444 * Added short-hand declaration style to migrations (inspiration from Sexy Migrations, http://errtheblog.com/post/2381) [David Heinemeier Hansson]. Example:
1445
1446 create_table "products" do |t|
1447 t.column "shop_id", :integer
1448 t.column "creator_id", :integer
1449 t.column "name", :string, :default => "Untitled"
1450 t.column "value", :string, :default => "Untitled"
1451 t.column "created_at", :datetime
1452 t.column "updated_at", :datetime
1453 end
1454
1455 ...can now be written as:
1456
1457 create_table :products do |t|
1458 t.integer :shop_id, :creator_id
1459 t.string :name, :value, :default => "Untitled"
1460 t.timestamps
1461 end
1462
1463 * Use association name for the wrapper element when using .to_xml. Previous behavior lead to non-deterministic situations with STI and polymorphic associations. *Michael Koziarski, jstrachan*
1464
1465 * Improve performance of calling .create on has_many :through associations. *evan*
1466
1467 * Improved cloning performance by relying less on exception raising #8159 *Blaine*
1468
1469 * Added ActiveRecord::Base.inspect to return a column-view like #<Post id:integer, title:string, body:text> *David Heinemeier Hansson*
1470
1471 * Added yielding of Builder instance for ActiveRecord::Base#to_xml calls *David Heinemeier Hansson*
1472
1473 * Small additions and fixes for ActiveRecord documentation. Closes #7342 *Jeremy McAnally*
1474
1475 * Add helpful debugging info to the ActiveRecord::StatementInvalid exception in ActiveRecord::ConnectionAdapters::SqliteAdapter#table_structure. Closes #7925. *court3nay*
1476
1477 * SQLite: binary escaping works with $KCODE='u'. #7862 *tsuka*
1478
1479 * Base#to_xml supports serialized attributes. #7502 *jonathan*
1480
1481 * Base.update_all :order and :limit options. Useful for MySQL updates that must be ordered to avoid violating unique constraints. *Jeremy Kemper*
1482
1483 * Remove deprecated object transactions. People relying on this functionality should install the object_transactions plugin at http://code.bitsweat.net/svn/object_transactions. Closes #5637 *Michael Koziarski, Jeremy Kemper*
1484
1485 * PostgreSQL: remove DateTime -> Time downcast. Warning: do not enable translate_results for the C bindings if you have timestamps outside Time's domain. *Jeremy Kemper*
1486
1487 * find_or_create_by_* takes a hash so you can create with more attributes than are in the method name. For example, Person.find_or_create_by_name(:name => 'Henry', :comments => 'Hi new user!') is equivalent to Person.find_by_name('Henry') || Person.create(:name => 'Henry', :comments => 'Hi new user!'). #7368 *Josh Susser*
1488
1489 * Make sure with_scope takes both :select and :joins into account when setting :readonly. Allows you to save records you retrieve using method_missing on a has_many :through associations. *Michael Koziarski*
1490
1491 * Allow a polymorphic :source for has_many :through associations. Closes #7143 *protocool*
1492
1493 * Consistent public/protected/private visibility for chained methods. #7813 *Dan Manges*
1494
1495 * Oracle: fix quoted primary keys and datetime overflow. #7798 *Michael Schoen*
1496
1497 * Consistently quote primary key column names. #7763 *toolmantim*
1498
1499 * Fixtures: fix YAML ordered map support. #2665 *Manuel Holtgrewe, nfbuckley*
1500
1501 * DateTimes assume the default timezone. #7764 *Geoff Buesing*
1502
1503 * Sybase: hide timestamp columns since they're inherently read-only. #7716 *Mike Joyce*
1504
1505 * Oracle: overflow Time to DateTime. #7718 *Michael Schoen*
1506
1507 * PostgreSQL: don't use async_exec and async_query with postgres-pr. #7727, #7762 *flowdelic, toolmantim*
1508
1509 * Fix has_many :through << with custom foreign keys. #6466, #7153 *naffis, Rich Collins*
1510
1511 * Test DateTime native type in migrations, including an edge case with dates
1512 during calendar reform. #7649, #7724 [fedot, Geoff Buesing]
1513 * SQLServer: correctly schema-dump tables with no indexes or descending indexes. #7333, #7703 *Jakob Skjerning, Tom Ward*
1514
1515 * SQLServer: recognize real column type as Ruby float. #7057 *sethladd, Tom Ward*
1516
1517 * Added fixtures :all as a way of loading all fixtures in the fixture directory at once #7214 *Manfred Stienstra*
1518
1519 * Added database connection as a yield parameter to ActiveRecord::Base.transaction so you can manually rollback [David Heinemeier Hansson]. Example:
1520
1521 transaction do |transaction|
1522 david.withdrawal(100)
1523 mary.deposit(100)
1524 transaction.rollback! # rolls back the transaction that was otherwise going to be successful
1525 end
1526
1527 * Made increment_counter/decrement_counter play nicely with optimistic locking, and added a more general update_counters method *Jamis Buck*
1528
1529 * Reworked David's query cache to be available as Model.cache {...}. For the duration of the block no select query should be run more then once. Any inserts/deletes/executes will flush the whole cache however *Tobias Lütke*
1530 Task.cache { Task.find(1); Task.find(1) } # => 1 query
1531
1532 * When dealing with SQLite3, use the table_info pragma helper, so that the bindings can do some translation for when sqlite3 breaks incompatibly between point releases. *Jamis Buck*
1533
1534 * Oracle: fix lob and text default handling. #7344 *gfriedrich, Michael Schoen*
1535
1536 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
1537
1538 * MySQL: blob and text columns may not have defaults in 5.x. Update fixtures schema for strict mode. #6695 *Dan Kubb*
1539
1540 * update_all can take a Hash argument. sanitize_sql splits into two methods for conditions and assignment since NULL values and delimiters are handled differently. #6583, #7365 *sandofsky, Assaf*
1541
1542 * MySQL: SET SQL_AUTO_IS_NULL=0 so 'where id is null' doesn't select the last inserted id. #6778 *Jonathan Viney, timc*
1543
1544 * Use Date#to_s(:db) for quoted dates. #7411 *Michael Schoen*
1545
1546 * Don't create instance writer methods for class attributes. Closes #7401 *Rick Olson*
1547
1548 * Docs: validations examples. #7343 *zackchandler*
1549
1550 * Add missing tests ensuring callbacks work with class inheritance. Closes #7339 *sandofsky*
1551
1552 * Fixtures use the table name and connection from set_fixture_class. #7330 *Anthony Eden*
1553
1554 * Remove useless code in #attribute_present? since 0 != blank?. Closes #7249 *Josh Susser*
1555
1556 * Fix minor doc typos. Closes #7157 *Josh Susser*
1557
1558 * Fix incorrect usage of #classify when creating the eager loading join statement. Closes #7044 *Josh Susser*
1559
1560 * SQLServer: quote table name in indexes query. #2928 *keithm@infused.org*
1561
1562 * Subclasses of an abstract class work with single-table inheritance. #5704, #7284 *BertG, nick+rails@ag.arizona.edu*
1563
1564 * Make sure sqlite3 driver closes open connections on disconnect *Rob Rasmussen*
1565
1566 * [DOC] clear up some ambiguity with the way has_and_belongs_to_many creates the default join table name. #7072 *Jeremy McAnally*
1567
1568 * change_column accepts :default => nil. Skip column options for primary keys. #6956, #7048 *Dan Manges, Jeremy Kemper*
1569
1570 * MySQL, PostgreSQL: change_column_default quotes the default value and doesn't lose column type information. #3987, #6664 *Jonathan Viney, Manfred Stienstra, altano@bigfoot.com*
1571
1572 * Oracle: create_table takes a :sequence_name option to override the 'tablename_seq' default. #7000 *Michael Schoen*
1573
1574 * MySQL: retain SSL settings on reconnect. #6976 *randyv2*
1575
1576 * Apply scoping during initialize instead of create. Fixes setting of foreign key when using find_or_initialize_by with scoping. *Cody Fauser*
1577
1578 * SQLServer: handle [quoted] table names. #6635 *rrich*
1579
1580 * acts_as_nested_set works with single-table inheritance. #6030 *Josh Susser*
1581
1582 * PostgreSQL, Oracle: correctly perform eager finds with :limit and :order. #4668, #7021 *eventualbuddha, Michael Schoen*
1583
1584 * Pass a range in :conditions to use the SQL BETWEEN operator. #6974 *Dan Manges*
1585 Student.find(:all, :conditions => { :grade => 9..12 })
1586
1587 * Fix the Oracle adapter for serialized attributes stored in CLOBs. Closes #6825 *mschoen, tdfowler*
1588
1589 * [DOCS] Apply more documentation for ActiveRecord Reflection. Closes #4055 *Robby Russell*
1590
1591 * [DOCS] Document :allow_nil option of #validate_uniqueness_of. Closes #3143 *Caio Chassot*
1592
1593 * Bring the sybase adapter up to scratch for 1.2 release. *jsheets*
1594
1595 * Rollback new_record? and id when an exception is raised in a save callback. #6910 *Ben Curren, outerim*
1596
1597 * Pushing a record on an association collection doesn't unnecessarily load all the associated records. *Obie Fernandez, Jeremy Kemper*
1598
1599 * Oracle: fix connection reset failure. #6846 *leonlleslie*
1600
1601 * Subclass instantiation doesn't try to explicitly require the corresponding subclass. #6840 *leei, Jeremy Kemper*
1602
1603 * fix faulty inheritance tests and that eager loading grabs the wrong inheritance column when the class of your association is an STI subclass. Closes #6859 *protocool*
1604
1605 * Consolidated different create and create! versions to call through to the base class with scope. This fixes inconsistencies, especially related to protected attribtues. Closes #5847 *Alexander Dymo, Tobias Lütke*
1606
1607 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
1608
1609 * Add AssociationCollection#create! to be consistent with AssociationCollection#create when dealing with a foreign key that is a protected attribute *Cody Fauser*
1610
1611 * Added counter optimization for AssociationCollection#any? so person.friends.any? won't actually load the full association if we have the count in a cheaper form *David Heinemeier Hansson*
1612
1613 * Change fixture_path to a class inheritable accessor allowing test cases to have their own custom set of fixtures. #6672 *Zach Dennis*
1614
1615 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
1616
1617 * Simplify query_attribute by typecasting the attribute value and checking whether it's nil, false, zero or blank. #6659 *Jonathan Viney*
1618
1619 * validates_numericality_of uses \A \Z to ensure the entire string matches rather than ^ $ which may match one valid line of a multiline string. #5716 *Andreas Schwarz*
1620
1621 * Run validations in the order they were declared. #6657 *obrie*
1622
1623 * MySQL: detect when a NOT NULL column without a default value is misreported as default ''. Can't detect for string, text, and binary columns since '' is a legitimate default. #6156 *simon@redhillconsulting.com.au, obrie, Jonathan Viney, Jeremy Kemper*
1624
1625 * Simplify association proxy implementation by factoring construct_scope out of method_missing. #6643 *martin*
1626
1627 * Oracle: automatically detect the primary key. #6594 *vesaria, Michael Schoen*
1628
1629 * Oracle: to increase performance, prefetch 100 rows and enable similar cursor sharing. Both are configurable in database.yml. #6607 *philbogle@gmail.com, ray.fortna@jobster.com, Michael Schoen*
1630
1631 * Don't inspect unloaded associations. #2905 *lmarlow*
1632
1633 * SQLite: use AUTOINCREMENT primary key in >= 3.1.0. #6588, #6616 *careo, lukfugl*
1634
1635 * Cache inheritance_column. #6592 *Stefan Kaes*
1636
1637 * Firebird: decimal/numeric support. #6408 *macrnic*
1638
1639 * make add_order a tad faster. #6567 *Stefan Kaes*
1640
1641 * Find with :include respects scoped :order. #5850
1642
1643 * Support nil and Array in :conditions => { attr => value } hashes. #6548 *Assaf, Jeremy Kemper*
1644 find(:all, :conditions => { :topic_id => [1, 2, 3], :last_read => nil }
1645
1646 * Consistently use LOWER() for uniqueness validations (rather than mixing with UPPER()) so the database can always use a functional index on the lowercased column. #6495 *Si*
1647
1648 * SQLite: fix calculations workaround, remove count(distinct) query rewrite, cleanup test connection scripts. *Jeremy Kemper*
1649
1650 * SQLite: count(distinct) queries supported in >= 3.2.6. #6544 *Bob Silva*
1651
1652 * Dynamically generate reader methods for serialized attributes. #6362 *Stefan Kaes*
1653
1654 * Deprecation: object transactions warning. *Jeremy Kemper*
1655
1656 * has_one :dependent => :nullify ignores nil associates. #4848, #6528 *bellis@deepthought.org, janovetz, Jeremy Kemper*
1657
1658 * Oracle: resolve test failures, use prefetched primary key for inserts, check for null defaults, fix limited id selection for eager loading. Factor out some common methods from all adapters. #6515 *Michael Schoen*
1659
1660 * Make add_column use the options hash with the Sqlite Adapter. Closes #6464 *obrie*
1661
1662 * Document other options available to migration's add_column. #6419 *grg*
1663
1664 * MySQL: all_hashes compatibility with old MysqlRes class. #6429, #6601 *Jeremy Kemper*
1665
1666 * Fix has_many :through to add the appropriate conditions when going through an association using STI. Closes #5783. *Jonathan Viney*
1667
1668 * fix select_limited_ids_list issues in postgresql, retain current behavior in other adapters *Rick Olson*
1669
1670 * Restore eager condition interpolation, document it's differences *Rick Olson*
1671
1672 * Don't rollback in teardown unless a transaction was started. Don't start a transaction in create_fixtures if a transaction is started. #6282 *Jacob Fugal, Jeremy Kemper*
1673
1674 * Add #delete support to has_many :through associations. Closes #6049 *Martin Landers*
1675
1676 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
1677
1678 * Removes the ability for eager loaded conditions to be interpolated, since there is no model instance to use as a context for interpolation. #5553 *turnip@turnipspatch.com*
1679
1680 * Added timeout option to SQLite3 configurations to deal more gracefully with SQLite3::BusyException, now the connection can instead retry for x seconds to see if the db clears up before throwing that exception #6126 *wreese@gmail.com*
1681
1682 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*
1683
1684 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
1685
1686 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
1687
1688 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
1689
1690 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
1691
1692 * Association collections have an _ids reader method to match the existing writer for collection_select convenience (e.g. employee.task_ids). The writer method skips blank ids so you can safely do @employee.task_ids = params[:tasks] without checking every time for an empty list or blank values. #1887, #5780 *Michael Schuerig*
1693
1694 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
1695
1696 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*
1697
1698 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*
1699

1704 * Deprecation tests. Remove warnings for dynamic finders and for the foo_count method if it's also an attribute. *Jeremy Kemper*
1705
1706 * Mock Time.now for more accurate Touch mixin tests. #6213 *Dan Peterson*
1707
1708 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
1709
1710 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
1711
1712 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
1713
1714 * Fixed the Ruby/MySQL adapter we ship with Active Record to work with the new authentication handshake that was introduced in MySQL 4.1, along with the other protocol changes made at that time #5723 *jimw@mysql.com*
1715
1716 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
1717
1718 * Document validates_presences_of behavior with booleans: you probably want validates_inclusion_of :attr, :in => [true, false]. #2253 *Bob Silva*
1719
1720 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
1721
1722 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
1723
1724 * Deprecation: update docs. #5998 *Jakob Skjerning, Kevin Clark*
1725
1726 * Add some XmlSerialization tests for ActiveRecord *Rick Olson*
1727
1728 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
1729
1730 * Tighten rescue clauses. #5985 *james@grayproductions.net*
1731
1732 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
1733
1734 * has_one supports the :dependent => :delete option which skips the typical callback chain and deletes the associated object directly from the database. #5927 *Chris Mear, Jonathan Viney*
1735
1736 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
1737
1738 * SQLServer: work around bug where some unambiguous date formats are not correctly identified if the session language is set to german. #5894 *Tom Ward, kruth@bfpi*
1739
1740 * SQLServer: fix eager association test. #5901 *Tom Ward*
1741
1742 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
1743
1744 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
1745
1746 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*
1747
1748 * MySQL: update test schema for MySQL 5 strict mode. #5861 *Tom Ward*
1749
1750 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
1751
1752 * Pushing a record onto a has_many :through sets the association's foreign key to the associate's primary key and adds it to the correct association. #5815, #5829 *Josh Susser*
1753
1754 * Add records to has_many :through using <<, push, and concat by creating the association record. Raise if base or associate are new records since both ids are required to create the association. #build raises since you can't associate an unsaved record. #create! takes an attributes hash and creates the associated record and its association in a transaction. *Jeremy Kemper*
1755
1756 # Create a tagging to associate the post and tag.
1757 post.tags << Tag.find_by_name('old')
1758 post.tags.create! :name => 'general'
1759
1760 # Would have been:
1761 post.taggings.create!(:tag => Tag.find_by_name('finally')
1762 transaction do
1763 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
1764 end
1765
1766 * Cache nil results for :included has_one associations also. #5787 *Michael Schoen*
1767
1768 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
1769
1770 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
1771 Example: Invoice::Lineitem is given table name invoice_lineitems
1772
1773 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
1774 # people_active_last_name_index, people_active_deactivated_at_index
1775 add_index :people, [:active, :last_name]
1776 add_index :people, [:active, :deactivated_at]
1777 remove_index :people, [:active, :last_name]
1778 remove_index :people, [:active, :deactivated_at]
1779
1780 WARNING: backward-incompatibility. Multicolumn indexes created before this

1785
1786 * Fix for deep includes on the same association. *richcollins@gmail.com*
1787
1788 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
1789
1790 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
1791
1792 * Document find's :from option. Closes #5762. *andrew@redlinesoftware.com*
1793
1794 * PostgreSQL: autodetected sequences work correctly with multiple schemas. Rely on the schema search_path instead of explicitly qualifying the sequence name with its schema. #5280 *guy.naor@famundo.com*
1795
1796 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
1797
1798 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
1799
1800 * Add documentation for how to disable timestamps on a per model basis. Closes #5684. *matt@mattmargolis.net Marcel Molina Jr.*
1801
1802 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
1803
1804 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
1805
1806 * Formally deprecate the deprecated finders. *Michael Koziarski*
1807

1845
1846 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*

1853
1854 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
1855
1856 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
1857
1858 * Oracle: use nonblocking queries if allow_concurrency is set, fix pessimistic locking, don't guess date vs. time by default (set OracleAdapter.emulate_dates = true for the old behavior), adapter cleanup. #5635 *Michael Schoen*
1859
1860 * Fixed a few Oracle issues: Allows Oracle's odd date handling to still work consistently within #to_xml, Passes test that hardcode insert statement by dropping the :id column, Updated RUNNING_UNIT_TESTS with Oracle instructions, Corrects method signature for #exec #5294 *Michael Schoen*
1861
1862 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
1863
1864 * Minor tweak to improve performance of ActiveRecord::Base#to_param.
1865
1866 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
1867
1868 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
1869
1870 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
1871
1872 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
1873

1876 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
1877
1878 * Row locking. Provide a locking clause with the :lock finder option or true for the default "FOR UPDATE". Use the #lock! method to obtain a row lock on a single record (reloads the record with :lock => true). *Shugo Maeda*
1879 # Obtain an exclusive lock on person 1 so we can safely increment visits.
1880 Person.transaction do
1881 # select * from people where id=1 for update
1882 person = Person.find(1, :lock => true)
1883 person.visits += 1
1884 person.save!
1885 end
1886
1887 * PostgreSQL: introduce allow_concurrency option which determines whether to use blocking or asynchronous #execute. Adapters with blocking #execute will deadlock Ruby threads. The default value is ActiveRecord::Base.allow_concurrency. *Jeremy Kemper*

1894
1895 * Refactored ActiveRecord::Base.to_xml to become a delegate for XmlSerializer, which restores sanity to the mega method. This refactoring also reinstates the opinions that type="string" is redundant and ugly and nil-differentiation is not a concern of serialization *David Heinemeier Hansson*
1896
1897 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
1898
1899 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
1900
1901 ...is the same as:
1902 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
1903
1904 This makes it easier to pass in the options from a form or otherwise outside.
1905

1916
1917 * Fixed that :includes merged from with_scope won't cause the same association to be loaded more than once if repetition occurs in the clauses #5253 *alex@purefiction.net*
1918
1919 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
1920
1921 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
1922
1923 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
1924 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
1925 Foo.find(:first, :conditions => ['bar_id = ?', bar])
1926
1927 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
1928
1929 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
1930
1931 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*

1945
1946 * Fix Oracle boolean support and tests. Closes #5139. *Michael Schoen*
1947
1948 * create! no longer blows up when no attributes are passed and a :create scope is in effect (e.g. foo.bars.create! failed whereas foo.bars.create!({}) didn't.) *Jeremy Kemper*
1949
1950 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
1951
1952 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
1953

2050
2051 * Don't create instance writer methods for class attributes. *Rick Olson*

2054
2055 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
2056

2100
2101 * fix faulty inheritance tests and that eager loading grabs the wrong inheritance column when the class of your association is an STI subclass. Closes #6859 *protocool*
2102
2103 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
2104

2163
2164 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*

2187
2188 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
2189
2190 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
2191
2192 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
2193
2194 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
2195
2196 * has_one supports the :dependent => :delete option which skips the typical callback chain and deletes the associated object directly from the database. #5927 *Chris Mear, Jonathan Viney*
2197
2198 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
2199
2200 * SQLServer: work around bug where some unambiguous date formats are not correctly identified if the session language is set to german. #5894 *Tom Ward, kruth@bfpi*
2201
2202 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
2203
2204 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
2205
2206 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*
2207
2208 * MySQL: update test schema for MySQL 5 strict mode. #5861 *Tom Ward*
2209
2210 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2211
2212 * Pushing a record onto a has_many :through sets the association's foreign key to the associate's primary key and adds it to the correct association. #5815, #5829 *Josh Susser*
2213
2214 * Add records to has_many :through using <<, push, and concat by creating the association record. Raise if base or associate are new records since both ids are required to create the association. #build raises since you can't associate an unsaved record. #create! takes an attributes hash and creates the associated record and its association in a transaction. *Jeremy Kemper*
2215
2216 # Create a tagging to associate the post and tag.
2217 post.tags << Tag.find_by_name('old')
2218 post.tags.create! :name => 'general'
2219
2220 # Would have been:
2221 post.taggings.create!(:tag => Tag.find_by_name('finally')
2222 transaction do
2223 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
2224 end
2225
2226 * Cache nil results for :included has_one associations also. #5787 *Michael Schoen*
2227
2228 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
2229
2230 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
2231 Example: Invoice::Lineitem is given table name invoice_lineitems
2232
2233 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2234 # people_active_last_name_index, people_active_deactivated_at_index
2235 add_index :people, [:active, :last_name]
2236 add_index :people, [:active, :deactivated_at]
2237 remove_index :people, [:active, :last_name]
2238 remove_index :people, [:active, :deactivated_at]
2239
2240 WARNING: backward-incompatibility. Multicolumn indexes created before this
2241 revision were named using the first column name only. Now they're uniquely
2242 named using all indexed columns.
2243
2244 To remove an old multicolumn index, remove_index :table_name, :first_column
2245
2246 * Fix for deep includes on the same association. *richcollins@gmail.com*
2247
2248 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
2249
2250 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
2251
2252 * PostgreSQL: autodetected sequences work correctly with multiple schemas. Rely on the schema search_path instead of explicitly qualifying the sequence name with its schema. #5280 *guy.naor@famundo.com*
2253
2254 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
2255
2256 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
2257
2258 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
2259
2260 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
2261
2262 * Formally deprecate the deprecated finders. *Michael Koziarski*
2263
2264 * Formally deprecate rich associations. *Michael Koziarski*
2265
2266 * Fixed that default timezones for new / initialize should uphold utc setting #5709 *daniluk@yahoo.com*
2267
2268 * Fix announcement of very long migration names. #5722 *blake@near-time.com*
2269
2270 * The exists? class method should treat a string argument as an id rather than as conditions. #5698 *jeremy@planetargon.com*
2271
2272 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
2273
2274 * Added support for conditions on Base.exists? #5689 [Josh Peek]. Examples:
2275
2276 assert (Topic.exists?(:author_name => "David"))
2277 assert (Topic.exists?(:author_name => "Mary", :approved => true))
2278 assert (Topic.exists?(["parent_id = ?", 1]))
2279
2280 * Schema dumper quotes date :default values. *Dave Thomas*
2281
2282 * Calculate sum with SQL, not Enumerable on HasManyThrough Associations. *Dan Peterson*
2283
2284 * Factor the attribute#{suffix} methods out of method_missing for easier extension. *Jeremy Kemper*
2285
2286 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
2287
2288 * Allow #count through a has_many association to accept :include. *Dan Peterson*
2289
2290 * create_table rdoc: suggest :id => false for habtm join tables. *Zed Shaw*
2291
2292 * PostgreSQL: return array fields as strings. #4664 *Robby Russell*
2293
2294 * SQLServer: added tests to ensure all database statements are closed, refactored identity_insert management code to use blocks, removed update/delete rowcount code out of execute and into update/delete, changed insert to go through execute method, removed unused quoting methods, disabled pessimistic locking tests as feature is currently unsupported, fixed RakeFile to load sqlserver specific tests whether running in ado or odbc mode, fixed support for recently added decimal types, added support for limits on integer types. #5670 *Tom Ward*
2295
2296 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2297
2298 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2299
2300 * Numeric and decimal columns map to BigDecimal instead of Float. Those with scale 0 map to Integer. #5454 *robbat2@gentoo.org, work@ashleymoran.me.uk*
2301
2302 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*

2304 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2305
2306 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2307
2308 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2309
2310 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2311
2312 * Oracle: use nonblocking queries if allow_concurrency is set, fix pessimistic locking, don't guess date vs. time by default (set OracleAdapter.emulate_dates = true for the old behavior), adapter cleanup. #5635 *Michael Schoen*
2313
2314 * Fixed a few Oracle issues: Allows Oracle's odd date handling to still work consistently within #to_xml, Passes test that hardcode insert statement by dropping the :id column, Updated RUNNING_UNIT_TESTS with Oracle instructions, Corrects method signature for #exec #5294 *Michael Schoen*
2315
2316 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2317
2318 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2319
2320 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2321
2322 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2323
2324 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2325
2326 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2327
2328 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2329
2330 * Row locking. Provide a locking clause with the :lock finder option or true for the default "FOR UPDATE". Use the #lock! method to obtain a row lock on a single record (reloads the record with :lock => true). *Shugo Maeda*
2331 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2332 Person.transaction do
2333 # select * from people where id=1 for update
2334 person = Person.find(1, :lock => true)
2335 person.visits += 1
2336 person.save!
2337 end
2338
2339 * PostgreSQL: introduce allow_concurrency option which determines whether to use blocking or asynchronous #execute. Adapters with blocking #execute will deadlock Ruby threads. The default value is ActiveRecord::Base.allow_concurrency. *Jeremy Kemper*
2340
2341 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2342
2343 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2344
2345 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2346
2347 * Refactored ActiveRecord::Base.to_xml to become a delegate for XmlSerializer, which restores sanity to the mega method. This refactoring also reinstates the opinions that type="string" is redundant and ugly and nil-differentiation is not a concern of serialization *David Heinemeier Hansson*
2348
2349 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2350
2351 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2352
2353 ...is the same as:
2354 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2355
2356 This makes it easier to pass in the options from a form or otherwise outside.
2357
2358
2359 * Fixed issues with BLOB limits, charsets, and booleans for Firebird #5194, #5191, #5189 *kennethkunz@gmail.com*

2362
2363 * Fixed migration trouble with SQLite when NOT NULL is used in the new definition #5215 *greg@lapcominc.com*
2364
2365 * Fixed problems with eager loading and counting on SQL Server #5212 *kajism@yahoo.com*
2366
2367 * Fixed that count distinct should use the selected column even when using :include #5251 *anna@wota.jp*
2368
2369 * Fixed that :includes merged from with_scope won't cause the same association to be loaded more than once if repetition occurs in the clauses #5253 *alex@purefiction.net*
2370
2371 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
2372
2373 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
2374
2375 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
2376 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
2377 Foo.find(:first, :conditions => ['bar_id = ?', bar])
2378
2379 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
2380
2381 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
2382
2383 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*
2384
2385 * Provide Association Extensions access to the instance that the association is being accessed from.
2386 Closes #4433 *Josh Susser*
2387
2388 * Update OpenBase adaterp's maintainer's email address. Closes #5176. *Derrick Spell*
2389
2390 * Add a quick note about :select and eagerly included associations. *Rick Olson*
2391
2392 * Add docs for the :as option in has_one associations. Closes #5144 *cdcarter@gmail.com*
2393
2394 * Fixed that has_many collections shouldn't load the entire association to do build or create *David Heinemeier Hansson*
2395
2396 * Added :allow_nil option for aggregations #5091 *Ian White*
2397
2398 * Fix Oracle boolean support and tests. Closes #5139. *Michael Schoen*
2399
2400 * create! no longer blows up when no attributes are passed and a :create scope is in effect (e.g. foo.bars.create! failed whereas foo.bars.create!({}) didn't.) *Jeremy Kemper*
2401
2402 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2403
2404 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2405
2406 * PostgreSQL: migrations support :limit with :integer columns by mapping limit < 4 to smallint, > 4 to bigint, and anything else to integer. #2900 *keegan@thebasement.org*

2510
2511 * Support eager includes when going through a polymorphic has_many association. *Rick Olson*
2512
2513 * Added support for eagerly including polymorphic has_one associations. (closes #4525) *Rick Olson*

2517 end
2518
2519 Post.find :all, :include => :tagging

2522
2523 * Added support for going through a polymorphic has_many association: (closes #4401) *Rick Olson*
2524

2528 end
2529
2530 class Firm < ActiveRecord::Base
2531 has_many :photo_collections
2532 has_many :photos, :through => :photo_collections

2538
2539 * Changed those private ActiveRecord methods to take optional third argument :auto instead of nil for performance optimizations. (closes #4456) *Stefan*
2540
2541 * Private ActiveRecord methods add_limit!, add_joins!, and add_conditions! take an OPTIONAL third argument 'scope' (closes #4456) *Rick Olson*
2542
2543 * DEPRECATED: Using additional attributes on has_and_belongs_to_many associations. Instead upgrade your association to be a real join model *David Heinemeier Hansson*
2544
2545 * Fixed that records returned from has_and_belongs_to_many associations with additional attributes should be marked as read only (fixes #4512) *David Heinemeier Hansson*
2546
2547 * Do not implicitly mark recordss of has_many :through as readonly but do mark habtm records as readonly (eventually only on join tables without rich attributes). *Marcel Mollina Jr.*
2548
2549 * Fixed broken OCIAdapter #4457 *Michael Schoen*
2550
2551
2552 ## 1.14.0 (March 27th, 2006) ##
2553
2554 * Replace 'rescue Object' with a finer grained rescue. Closes #4431. *Nicholas Seckar*
2555
2556 * Fixed eager loading so that an aliased table cannot clash with a has_and_belongs_to_many join table *Rick Olson*
2557
2558 * Add support for :include to with_scope *andrew@redlinesoftware.com*
2559
2560 * Support the use of public synonyms with the Oracle adapter; required ruby-oci8 v0.1.14 #4390 *Michael Schoen*
2561
2562 * Change periods (.) in table aliases to _'s. Closes #4251 *jeff@ministrycentered.com*
2563
2564 * Changed has_and_belongs_to_many join to INNER JOIN for Mysql 3.23.x. Closes #4348 *Rick Olson*
2565
2566 * Fixed issue that kept :select options from being scoped *Rick Olson*
2567
2568 * Fixed db_schema_import when binary types are present #3101 *David Heinemeier Hansson*
2569
2570 * Fixed that MySQL enums should always be returned as strings #3501 *David Heinemeier Hansson*
2571
2572 * Change has_many :through to use the :source option to specify the source association. :class_name is now ignored. *Rick Olson*
2573
2574 class Connection < ActiveRecord::Base
2575 belongs_to :user
2576 belongs_to :channel
2577 end
2578
2579 class Channel < ActiveRecord::Base
2580 has_many :connections
2581 has_many :contacts, :through => :connections, :class_name => 'User' # OLD
2582 has_many :contacts, :through => :connections, :source => :user # NEW
2583 end
2584
2585 * Fixed DB2 adapter so nullable columns will be determines correctly now and quotes from column default values will be removed #4350 *contact@maik-schmidt.de*
2586
2587 * Allow overriding of find parameters in scoped has_many :through calls *Rick Olson*
2588
2589 In this example, :include => false disables the default eager association from loading. :select changes the standard
2590 select clause. :joins specifies a join that is added to the end of the has_many :through query.
2591
2592 class Post < ActiveRecord::Base
2593 has_many :tags, :through => :taggings, :include => :tagging do
2594 def add_joins_and_select
2595 find :all, :select => 'tags.*, authors.id as author_id', :include => false,
2596 :joins => 'left outer join posts on taggings.taggable_id = posts.id left outer join authors on posts.author_id = authors.id'
2597 end
2598 end
2599 end
2600
2601 * Fixed that schema changes while the database was open would break any connections to an SQLite database (now we reconnect if that error is throw) *David Heinemeier Hansson*
2602
2603 * Don't classify the has_one class when eager loading, it is already singular. Add tests. (closes #4117) *Jonathan Viney*
2604
2605 * Quit ignoring default :include options in has_many :through calls *Mark James*
2606
2607 * Allow has_many :through associations to find the source association by setting a custom class (closes #4307) *Jonathan Viney*
2608
2609 * Eager Loading support added for has_many :through => :has_many associations (see below). *Rick Olson*
2610
2611 * Allow has_many :through to work on has_many associations (closes #3864) [sco@scottraymond.net] Example:
2612
2613 class Firm < ActiveRecord::Base
2614 has_many :clients
2615 has_many :invoices, :through => :clients
2616 end
2617
2618 class Client < ActiveRecord::Base
2619 belongs_to :firm
2620 has_many :invoices
2621 end
2622
2623 class Invoice < ActiveRecord::Base
2624 belongs_to :client
2625 end
2626
2627 * Raise error when trying to select many polymorphic objects with has_many :through or :include (closes #4226) *Josh Susser*
2628
2629 * Fixed has_many :through to include :conditions set on the :through association. closes #4020 *Jonathan Viney*
2630
2631 * Fix that has_many :through honors the foreign key set by the belongs_to association in the join model (closes #4259) *andylien@gmail.com / Rick Olson*
2632
2633 * SQL Server adapter gets some love #4298 *Ryan Tomayko*
2634
2635 * Added OpenBase database adapter that builds on top of the http://www.spice-of-life.net/ruby-openbase/ driver. All functionality except LIMIT/OFFSET is supported #3528 *derrickspell@cdmplus.com*
2636
2637 * Rework table aliasing to account for truncated table aliases. Add smarter table aliasing when doing eager loading of STI associations. This allows you to use the association name in the order/where clause. [Jonathan Viney / Rick Olson] #4108 Example (SpecialComment is using STI):
2638
2639 Author.find(:all, :include => { :posts => :special_comments }, :order => 'special_comments.body')
2640
2641 * Add AbstractAdapter#table_alias_for to create table aliases according to the rules of the current adapter. *Rick Olson*
2642
2643 * Provide access to the underlying database connection through Adapter#raw_connection. Enables the use of db-specific methods without complicating the adapters. #2090 *Michael Koziarski*
2644
2645 * Remove broken attempts at handling columns with a default of 'now()' in the postgresql adapter. #2257 *Michael Koziarski*
2646
2647 * Added connection#current_database that'll return of the current database (only works in MySQL, SQL Server, and Oracle so far -- please help implement for the rest of the adapters) #3663 *Tom Ward*
2648
2649 * Fixed that Migration#execute would have the table name prefix appended to its query #4110 *mark.imbriaco@pobox.com*
2650
2651 * Make all tinyint(1) variants act like boolean in mysql (tinyint(1) unsigned, etc.) *Jamis Buck*
2652
2653 * Use association's :conditions when eager loading. [Jeremy Evans] #4144
2654
2655 * Alias the has_and_belongs_to_many join table on eager includes. #4106 *Jeremy Evans*
2656
2657 This statement would normally error because the projects_developers table is joined twice, and therefore joined_on would be ambiguous.
2658
2659 Developer.find(:all, :include => {:projects => :developers}, :conditions => 'join_project_developers.joined_on IS NOT NULL')
2660
2661 * Oracle adapter gets some love #4230 *Michael Schoen*
2662
2663 * Changes :text to CLOB rather than BLOB [Moses Hohman]
2664 * Fixes an issue with nil numeric length/scales (several)
2665 * Implements support for XMLTYPE columns [wilig / Kubo Takehiro]
2666 * Tweaks a unit test to get it all green again
2667 * Adds support for #current_database
2668
2669 * Added Base.abstract_class? that marks which classes are not part of the Active Record hierarchy #3704 *Rick Olson*
2670
2671 class CachedModel < ActiveRecord::Base
2672 self.abstract_class = true
2673 end
2674
2675 class Post < CachedModel
2676 end
2677
2678 CachedModel.abstract_class?
2679 => true
2680
2681 Post.abstract_class?
2682 => false
2683
2684 Post.base_class
2685 => Post
2686
2687 Post.table_name
2688 => 'posts'
2689
2690 * Allow :dependent options to be used with polymorphic joins. #3820 *Rick Olson*
2691
2692 class Foo < ActiveRecord::Base
2693 has_many :attachments, :as => :attachable, :dependent => :delete_all
2694 end
2695
2696 * Nicer error message on has_many :through when :through reflection can not be found. #4042 *court3nay*
2697
2698 * Upgrade to Transaction::Simple 1.3 *Jamis Buck*
2699
2700 * Catch FixtureClassNotFound when using instantiated fixtures on a fixture that has no ActiveRecord model *Rick Olson*
2701
2702 * Allow ordering of calculated results and/or grouped fields in calculations *solo@gatelys.com*
2703
2704 * Make ActiveRecord::Base#save! return true instead of nil on success. #4173 *johan@johansorensen.com*
2705
2706 * Dynamically set allow_concurrency. #4044 *Stefan Kaes*
2707
2708 * Added Base#to_xml that'll turn the current record into a XML representation [David Heinemeier Hansson]. Example:
2709
2710 topic.to_xml
2711
2712 ...returns:
2713

2771
2772 * Allow :counter_cache to take a column name for custom counter cache columns *Jamis Buck*
2773
2774 * Documentation fixes for :dependent *robby@planetargon.com*
2775
2776 * Stop the MySQL adapter crashing when views are present. #3782 *Jonathan Viney*
2777
2778 * Don't classify the belongs_to class, it is already singular #4117 *keithm@infused.org*
2779
2780 * Allow set_fixture_class to take Classes instead of strings for a class in a module. Raise FixtureClassNotFound if a fixture can't load. *Rick Olson*
2781
2782 * Fix quoting of inheritance column for STI eager loading #4098 *Jonathan Viney <jonathan@bluewire.net.nz>*
2783
2784 * Added smarter table aliasing for eager associations for multiple self joins #3580 *Rick Olson*
2785
2786 * The first time a table is referenced in a join, no alias is used.
2787 * After that, the parent class name and the reflection name are used.
2788
2789 Tree.find(:all, :include => :children) # LEFT OUTER JOIN trees AS tree_children ...
2790
2791 * Any additional join references get a numerical suffix like '_2', '_3', etc.
2792
2793 * Fixed eager loading problems with single-table inheritance #3580 [Rick Olson]. Post.find(:all, :include => :special_comments) now returns all posts, and any special comments that the posts may have. And made STI work with has_many :through and polymorphic belongs_to.
2794
2795 * Added cascading eager loading that allows for queries like Author.find(:all, :include=> { :posts=> :comments }), which will fetch all authors, their posts, and the comments belonging to those posts in a single query (using LEFT OUTER JOIN) #3913 [anna@wota.jp]. Examples:
2796
2797 # cascaded in two levels
2798 >> Author.find(:all, :include=>{:posts=>:comments})
2799 => authors
2800 +- posts
2801 +- comments
2802
2803 # cascaded in two levels and normal association
2804 >> Author.find(:all, :include=>[{:posts=>:comments}, :categorizations])
2805 => authors
2806 +- posts
2807 +- comments
2808 +- categorizations
2809
2810 # cascaded in two levels with two has_many associations
2811 >> Author.find(:all, :include=>{:posts=>[:comments, :categorizations]})
2812 => authors
2813 +- posts
2814 +- comments
2815 +- categorizations
2816
2817 # cascaded in three levels
2818 >> Company.find(:all, :include=>{:groups=>{:members=>{:favorites}}})
2819 => companies
2820 +- groups
2821 +- members
2822 +- favorites
2823
2824 * Make counter cache work when replacing an association #3245 *eugenol@gmail.com*
2825
2826 * Make migrations verbose *Jamis Buck*
2827
2828 * Make counter_cache work with polymorphic belongs_to *Jamis Buck*
2829
2830 * Fixed that calling HasOneProxy#build_model repeatedly would cause saving to happen #4058 *anna@wota.jp*
2831
2832 * Added Sybase database adapter that relies on the Sybase Open Client bindings (see http://raa.ruby-lang.org/project/sybase-ctlib) #3765 [John Sheets]. It's almost completely Active Record compliant (including migrations), but has the following caveats:
2833
2834 * Does not support DATE SQL column types; use DATETIME instead.
2835 * Date columns on HABTM join tables are returned as String, not Time.
2836 * Insertions are potentially broken for :polymorphic join tables
2837 * BLOB column access not yet fully supported
2838
2839 * Clear stale, cached connections left behind by defunct threads. *Jeremy Kemper*
2840
2841 * CHANGED DEFAULT: set ActiveRecord::Base.allow_concurrency to false. Most AR usage is in single-threaded applications. *Jeremy Kemper*
2842
2843 * Renamed the "oci" adapter to "oracle", but kept the old name as an alias #4017 *Michael Schoen*
2844
2845 * Fixed that Base.save should always return false if the save didn't succeed, including if it has halted by before_save's #1861, #2477 *David Heinemeier Hansson*
2846
2847 * Speed up class -> connection caching and stale connection verification. #3979 *Stefan Kaes*
2848
2849 * Add set_fixture_class to allow the use of table name accessors with models which use set_table_name. *Kevin Clark*
2850
2851 * Added that fixtures to placed in subdirectories of the main fixture files are also loaded #3937 *dblack@wobblini.net*
2852
2853 * Define attribute query methods to avoid method_missing calls. #3677 *Jonathan Viney*
2854
2855 * ActiveRecord::Base.remove_connection explicitly closes database connections and doesn't corrupt the connection cache. Introducing the disconnect! instance method for the PostgreSQL, MySQL, and SQL Server adapters; implementations for the others are welcome. #3591 *Simon Stapleton, Tom Ward*
2856
2857 * Added support for nested scopes #3407 [anna@wota.jp]. Examples:
2858
2859 Developer.with_scope(:find => { :conditions => "salary > 10000", :limit => 10 }) do
2860 Developer.find(:all) # => SELECT * FROM developers WHERE (salary > 10000) LIMIT 10
2861
2862 # inner rule is used. (all previous parameters are ignored)
2863 Developer.with_exclusive_scope(:find => { :conditions => "name = 'Jamis'" }) do
2864 Developer.find(:all) # => SELECT * FROM developers WHERE (name = 'Jamis')
2865 end
2866
2867 # parameters are merged
2868 Developer.with_scope(:find => { :conditions => "name = 'Jamis'" }) do
2869 Developer.find(:all) # => SELECT * FROM developers WHERE (( salary > 10000 ) AND ( name = 'Jamis' )) LIMIT 10
2870 end
2871 end
2872
2873 * Fixed db2 connection with empty user_name and auth options #3622 *phurley@gmail.com*
2874
2875 * Fixed validates_length_of to work on UTF-8 strings by using characters instead of bytes #3699 *Masao Mutoh*
2876
2877 * Fixed that reflections would bleed across class boundaries in single-table inheritance setups #3796 *Lars Pind*
2878
2879 * Added calculations: Base.count, Base.average, Base.sum, Base.minimum, Base.maxmium, and the generic Base.calculate. All can be used with :group and :having. Calculations and statitics need no longer require custom SQL. #3958 [Rick Olson]. Examples:
2880
2881 Person.average :age
2882 Person.minimum :age
2883 Person.maximum :age
2884 Person.sum :salary, :group => :last_name
2885
2886 * Renamed Errors#count to Errors#size but kept an alias for the old name (and included an alias for length too) #3920 *Luke Redpath*
2887
2888 * Reflections don't attempt to resolve module nesting of association classes. Simplify type computation. *Jeremy Kemper*
2889
2890 * Improved the Oracle OCI Adapter with better performance for column reflection (from #3210), fixes to migrations (from #3476 and #3742), tweaks to unit tests (from #3610), and improved documentation (from #2446) #3879 *Aggregated by schoenm@earthlink.net*
2891
2892 * Fixed that the schema_info table used by ActiveRecord::Schema.define should respect table pre- and suffixes #3834 *rubyonrails@atyp.de*
2893
2894 * Added :select option to Base.count that'll allow you to select something else than * to be counted on. Especially important for count queries using DISTINCT #3839 *Stefan Kaes*
2895
2896 * Correct syntax error in mysql DDL, and make AAACreateTablesTest run first *Bob Silva*
2897
2898 * Allow :include to be used with has_many :through associations #3611 *Michael Schoen*
2899
2900 * PostgreSQL: smarter schema dumps using pk_and_sequence_for(table). #2920 *Blair Zajac*
2901
2902 * SQLServer: more compatible limit/offset emulation. #3779 *Tom Ward*
2903
2904 * Polymorphic join support for has_one associations (has_one :foo, :as => :bar) #3785 *Rick Olson*
2905
2906 * PostgreSQL: correctly parse negative integer column defaults. #3776 *bellis@deepthought.org*
2907
2908 * Fix problems with count when used with :include *Jeremy Hopple and Kevin Clark*
2909
2910 * ActiveRecord::RecordInvalid now states which validations failed in its default error message *Tobias Lütke*
2911
2912 * Using AssociationCollection#build with arrays of hashes should call build, not create *David Heinemeier Hansson*
2913
2914 * Remove definition of reloadable? from ActiveRecord::Base to make way for new Reloadable code. *Nicholas Seckar*
2915
2916 * Fixed schema handling for DB2 adapter that didn't work: an initial schema could be set, but it wasn't used when getting tables and indexes #3678 *Maik Schmidt*
2917
2918 * Support the :column option for remove_index with the PostgreSQL adapter. #3661 *Shugo Maeda*
2919
2920 * Add documentation for add_index and remove_index. #3600 *Manfred Stienstra <m.stienstra@fngtps.com>*
2921
2922 * If the OCI library is not available, raise an exception indicating as much. #3593 *Michael Schoen*
2923
2924 * Add explicit :order in finder tests as postgresql orders results differently by default. #3577. *Rick Olson*
2925
2926 * Make dynamic finders honor additional passed in :conditions. #3569 *Oleg Pudeyev <pudeyo@rpi.edu>, Marcel Molina Jr.*
2927
2928 * Show a meaningful error when the DB2 adapter cannot be loaded due to missing dependencies. *Nicholas Seckar*
2929
2930 * Make .count work for has_many associations with multi line finder sql *Michael Schoen*
2931
2932 * Add AR::Base.base_class for querying the ancestor AR::Base subclass *Jamis Buck*
2933
2934 * Allow configuration of the column used for optimistic locking *wilsonb@gmail.com*
2935
2936 * Don't hardcode 'id' in acts as list. *ror@philippeapril.com*
2937
2938 * Fix date errors for SQLServer in association tests. #3406 *Kevin Clark*
2939
2940 * Escape database name in MySQL adapter when creating and dropping databases. #3409 *anna@wota.jp*
2941
2942 * Disambiguate table names for columns in validates_uniqueness_of's WHERE clause. #3423 *alex.borovsky@gmail.com*
2943
2944 * .with_scope imposed create parameters now bypass attr_protected *Tobias Lütke*
2945
2946 * Don't raise an exception when there are more keys than there are named bind variables when sanitizing conditions. *Marcel Molina Jr.*
2947
2948 * Multiple enhancements and adjustments to DB2 adaptor. #3377 *contact@maik-schmidt.de*
2949
2950 * Sanitize scoped conditions. *Marcel Molina Jr.*
2951
2952 * Added option to Base.reflection_of_all_associations to specify a specific association to scope the call. For example Base.reflection_of_all_associations(:has_many) *David Heinemeier Hansson*
2953
2954 * Added ActiveRecord::SchemaDumper.ignore_tables which tells SchemaDumper which tables to ignore. Useful for tables with funky column like the ones required for tsearch2. *Tobias Lütke*
2955
2956 * SchemaDumper now doesn't fail anymore when there are unknown column types in the schema. Instead the table is ignored and a Comment is left in the schema.rb. *Tobias Lütke*
2957
2958 * Fixed that saving a model with multiple habtm associations would only save the first one. #3244 *yanowitz-rubyonrails@quantumfoam.org, Florian Weber*
2959
2960 * Fix change_column to work with PostgreSQL 7.x and 8.x. #3141 *wejn@box.cz, Rick Olson, Scott Barron*

2981 has_many :recent_comments, :class_name => "Comment", :limit => 10, :include => :author
2982 end
2983
2984 post.recent_comments.find(:all) # Uses LIMIT 10 and includes authors
2985 post.recent_comments.find(:all, :limit => nil) # Uses no limit but include authors
