2011-11-27 changelog & docs for GeneratedFeatureMethods
25 * Generated association methods are created within a separate module to allow overriding and
26 composition using `super`. For a class named `MyModel`, the module is named
27 `MyModel::GeneratedFeatureMethods`. It is included into the model class immediately after
28 the `generated_attributes_methods` module defined in ActiveModel, so association methods
29 override attribute methods of the same name. *Josh Susser*

2011-11-04 Add ActiveRecord::Relation#uniq for toggling DISTINCT in the SQL query
33 * Add ActiveRecord::Relation#uniq for generating unique queries.
34
35 Before:
36
37 Client.select('DISTINCT name')
38
39 After:
40
41 Client.select(:name).uniq
42
43 This also allows you to revert the unqueness in a relation:
44
45 Client.select(:name).uniq.uniq(false)

2011-11-04 AR changes to support creating ordered (asc, desc) indexes
49 * Support index sort order in sqlite, mysql and postgres adapters. *Vlad Jebelev*

2011-11-04 Convert CHANGELOGs to Markdown format.
51 * Allow the :class_name option for associations to take a symbol (:Client) in addition to
52 a string ('Client').
53
54 This is to avoid confusing newbies, and to be consistent with the fact that other options
55 like :foreign_key already allow a symbol or a string.
56
57 *Jon Leighton*
58
59 * In development mode the db:drop task also drops the test database. For symmetry with
60 the db:create task. *Dmitriy Kiriyenko*
61
62 * Added ActiveRecord::Base.store for declaring simple single-column key/value stores *DHH*
63
64 class User < ActiveRecord::Base
65 store :settings, accessors: [ :color, :homepage ]
66 end
67
68 u = User.new(color: 'black', homepage: '37signals.com')
69 u.color # Accessor stored attribute
70 u.settings[:country] = 'Denmark' # Any attribute, even if not specified with an accessor
71
72
73 * MySQL: case-insensitive uniqueness validation avoids calling LOWER when
74 the column already uses a case-insensitive collation. Fixes #561.
75
76 *Joseph Palermo*
77
78 * Transactional fixtures enlist all active database connections. You can test
79 models on different connections without disabling transactional fixtures.
80
81 *Jeremy Kemper*
82
83 * Add first_or_create, first_or_create!, first_or_initialize methods to Active Record. This is a
84 better approach over the old find_or_create_by dynamic methods because it's clearer which
85 arguments are used to find the record and which are used to create it:
86
87 User.where(:first_name => "Scarlett").first_or_create!(:last_name => "Johansson")
88
89 *Andrés Mejía*
90
91 * Fix nested attributes bug where _destroy parameter is taken into account
92 during :reject_if => :all_blank (fixes #2937)

2011-11-14 Sync CHANGELOGs from 3-1-stable
111 * Fix bug with PostgreSQLAdapter#indexes. When the search path has multiple schemas, spaces
112 were not being stripped from the schema names after the first.
113
114 *Sean Kirby*
115
116 * Preserve SELECT columns on the COUNT for finder_sql when possible. *GH 3503*

2011-11-04 Convert CHANGELOGs to Markdown format.
132 * Fix bug where building the conditions of a nested through association could potentially
133 modify the conditions of the through and/or source association. If you have experienced
134 bugs with conditions appearing in the wrong queries when using nested through associations,
135 this probably solves your problems. *GH #3271*
136
137 *Jon Leighton*
138
139 * If a record is removed from a has_many :through, all of the join records relating to that
140 record should also be removed from the through association's target.
141
142 *Jon Leighton*
143
144 * Fix adding multiple instances of the same record to a has_many :through. *GH #3425*
145
146 *Jon Leighton*
147
148 * Fix creating records in a through association with a polymorphic source type. *GH #3247*

2011-11-04 Convert CHANGELOGs to Markdown format.
156 ## Rails 3.1.1 (October 7, 2011) ##
157
158 * Add deprecation for the preload_associations method. Fixes #3022.
159
160 *Jon Leighton*
161
162 * Don't require a DB connection when loading a model that uses set_primary_key. GH #2807.
163
164 *Jon Leighton*
165
166 * Fix using select() with a habtm association, e.g. Person.friends.select(:name). GH #3030 and
167 \#2923.
168
169 *Hendy Tanata*
170
171 * Fix belongs_to polymorphic with custom primary key on target. GH #3104.
172
173 *Jon Leighton*
174
175 * CollectionProxy#replace should change the DB records rather than just mutating the array.
176 Fixes #3020.
177
178 *Jon Leighton*
179
180 * LRU cache in mysql and sqlite are now per-process caches.
181
182 * lib/active_record/connection_adapters/mysql_adapter.rb: LRU cache keys are per process id.
183 * lib/active_record/connection_adapters/sqlite_adapter.rb: ditto
184 *Aaron Patterson*
185
186 * Support bulk change_table in mysql2 adapter, as well as the mysql one. *Jon Leighton*
187
188 * If multiple parameters are sent representing a date, and some are blank, the
189 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]
190 * ActiveRecord::Base.establish_connection now takes a string that contains
191 a URI that specifies the connection configuration. For example:
192 ActiveRecord::Base.establish_connection 'postgres://localhost/foo'
193
194 * 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.
195
196 So if you were doing this and expecting the second argument to be nil:
197
198 User.find_by_username_and_group("sikachu")
199
200 You'll now get `ArgumentError: wrong number of arguments (1 for 2).` You'll then have to do this:
201
202 User.find_by_username_and_group("sikachu", nil)
203
204 *Prem Sichanugrist*
205
206
207 ## Rails 3.1.0 (August 30, 2011) ##
208
209 * Add a proxy_association method to association proxies, which can be called by association
210 extensions to access information about the association. This replaces proxy_owner etc with
211 proxy_association.owner.
212
213 *Jon Leighton*
214
215 * ActiveRecord::MacroReflection::AssociationReflection#build_record has a new method signature.
216
217 Before: def build_association(*options)
218 After: def build_association(*options, &block)
219
220 Users who are redefining this method to extend functionality should ensure that the block is
221 passed through to ActiveRecord::Base#new.
222
223 This change is necessary to fix https://github.com/rails/rails/issues/1842.
224
225 *Jon Leighton*
226
227 * AR#pluralize_table_names can be used to singularize/pluralize table name of an individual model:
228
229 class User < ActiveRecord::Base
230 self.pluralize_table_names = false
231 end
232
233 Previously this could only be set globally for all models through ActiveRecord::Base.pluralize_table_names. *Guillermo Iguaran*
234
235 * Add block setting of attributes to singular associations:
236
237 class User < ActiveRecord::Base
238 has_one :account
239 end
240
241 user.build_account{ |a| a.credit_limit => 100.0 }
242
243 The block is called after the instance has been initialized. *Andrew White*
244
245 * 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*
246
247 * CSV Fixtures are deprecated and support will be removed in Rails 3.2.0
248
249 * AR#new, AR#create, AR#create!, AR#update_attributes and AR#update_attributes! all accept a second hash as option that allows you
250 to specify which role to consider when assigning attributes. This is built on top of ActiveModel's
251 new mass assignment capabilities:
252
253 class Post < ActiveRecord::Base
254 attr_accessible :title
255 attr_accessible :title, :published_at, :as => :admin
256 end
257
258 Post.new(params[:post], :as => :admin)
259
260 assign_attributes() with similar API was also added and attributes=(params, guard) was deprecated.
261
262 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.
263
264 *Josh Kalderimis*
265
266 * default_scope can take a block, lambda, or any other object which responds to `call` for lazy
267 evaluation:
268
269 default_scope { ... }
270 default_scope lambda { ... }
271 default_scope method(:foo)
272
273 This feature was originally implemented by Tim Morgan, but was then removed in favour of
274 defining a 'default_scope' class method, but has now been added back in by Jon Leighton.
275 The relevant lighthouse ticket is #1812.
276
277 * Default scopes are now evaluated at the latest possible moment, to avoid problems where
278 scopes would be created which would implicitly contain the default scope, which would then
279 be impossible to get rid of via Model.unscoped.
280
281 Note that this means that if you are inspecting the internal structure of an
282 ActiveRecord::Relation, it will *not* contain the default scope, though the resulting
283 query will do. You can get a relation containing the default scope by calling
284 ActiveRecord#with_default_scope, though this is not part of the public API.
285
286 *Jon Leighton*
287
288 * If you wish to merge default scopes in special ways, it is recommended to define your default
289 scope as a class method and use the standard techniques for sharing code (inheritance, mixins,
290 etc.):
291
292 class Post < ActiveRecord::Base
293 def self.default_scope
294 where(:published => true).where(:hidden => false)
295 end
296 end
297
298 *Jon Leighton*
299
300 * PostgreSQL adapter only supports PostgreSQL version 8.2 and higher.
301
302 * ConnectionManagement middleware is changed to clean up the connection pool
303 after the rack body has been flushed.
304
305 * Added an update_column method on ActiveRecord. This new method updates a given attribute on an object, skipping validations and callbacks.
306 It is recommended to use #update_attribute unless you are sure you do not want to execute any callback, including the modification of
307 the updated_at column. It should not be called on new records.
308 Example:
309
310 User.first.update_column(:name, "sebastian") # => true
311
312 *Sebastian Martinez*
313
314 * Associations with a :through option can now use *any* association as the
315 through or source association, including other associations which have a
316 :through option and has_and_belongs_to_many associations
317
318 *Jon Leighton*
319
320 * The configuration for the current database connection is now accessible via
321 ActiveRecord::Base.connection_config. *fxn*
322
323 * limits and offsets are removed from COUNT queries unless both are supplied.
324 For example:
325
326 People.limit(1).count # => 'SELECT COUNT(*) FROM people'
327 People.offset(1).count # => 'SELECT COUNT(*) FROM people'
328 People.limit(1).offset(1).count # => 'SELECT COUNT(*) FROM people LIMIT 1 OFFSET 1'
329
330 *lighthouse #6262*
331
332 * ActiveRecord::Associations::AssociationProxy has been split. There is now an Association class
333 (and subclasses) which are responsible for operating on associations, and then a separate,
334 thin wrapper called CollectionProxy, which proxies collection associations.
335
336 This prevents namespace pollution, separates concerns, and will allow further refactorings.
337
338 Singular associations (has_one, belongs_to) no longer have a proxy at all. They simply return
339 the associated record or nil. This means that you should not use undocumented methods such
340 as bob.mother.create - use bob.create_mother instead.
341
342 *Jon Leighton*
343
344 * Make has_many :through associations work correctly when you build a record and then save it. This
345 requires you to set the :inverse_of option on the source reflection on the join model, like so:
346
347 class Post < ActiveRecord::Base
348 has_many :taggings
349 has_many :tags, :through => :taggings
350 end
351
352 class Tagging < ActiveRecord::Base
353 belongs_to :post
354 belongs_to :tag, :inverse_of => :tagging # :inverse_of must be set!
355 end
356
357 class Tag < ActiveRecord::Base
358 has_many :taggings
359 has_many :posts, :through => :taggings
360 end
361
362 post = Post.first
363 tag = post.tags.build :name => "ruby"
364 tag.save # will save a Taggable linking to the post
365
366 *Jon Leighton*
367
368 * Support the :dependent option on has_many :through associations. For historical and practical
369 reasons, :delete_all is the default deletion strategy employed by association.delete(*records),
370 despite the fact that the default strategy is :nullify for regular has_many. Also, this only
371 works at all if the source reflection is a belongs_to. For other situations, you should directly
372 modify the through association.
373
374 *Jon Leighton*
375
376 * Changed the behaviour of association.destroy for has_and_belongs_to_many and has_many :through.
377 From now on, 'destroy' or 'delete' on an association will be taken to mean 'get rid of the link',
378 not (necessarily) 'get rid of the associated records'.
379
380 Previously, has_and_belongs_to_many.destroy(*records) would destroy the records themselves. It
381 would not delete any records in the join table. Now, it deletes the records in the join table.
382
383 Previously, has_many_through.destroy(*records) would destroy the records themselves, and the
384 records in the join table. [Note: This has not always been the case; previous version of Rails
385 only deleted the records themselves.] Now, it destroys only the records in the join table.
386
387 Note that this change is backwards-incompatible to an extent, but there is unfortunately no
388 way to 'deprecate' it before changing it. The change is being made in order to have
389 consistency as to the meaning of 'destroy' or 'delete' across the different types of associations.
390
391 If you wish to destroy the records themselves, you can do records.association.each(&:destroy)
392
393 *Jon Leighton*
394
395 * 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*
396
397 Example:
398
399 change_table(:users, :bulk => true) do |t|
400 t.string :company_name
401 t.change :birthdate, :datetime
402 end
403
404 This will now result in:
405
406 ALTER TABLE `users` ADD COLUMN `company_name` varchar(255), CHANGE `updated_at` `updated_at` datetime DEFAULT NULL
407
408 * Removed support for accessing attributes on a has_and_belongs_to_many join table. This has been
409 documented as deprecated behaviour since April 2006. Please use has_many :through instead.
410 *Jon Leighton*
411
412 * Added a create_association! method for has_one and belongs_to associations. *Jon Leighton*
413
414 * Migration files generated from model and constructive migration generators
415 (for example, add_name_to_users) use the reversible migration's `change`
416 method instead of the ordinary `up` and `down` methods. *Prem Sichanugrist*
417
418 * Removed support for interpolating string SQL conditions on associations. Instead, you should
419 use a proc, like so:
420
421 Before:
422
423 has_many :things, :conditions => 'foo = #{bar}'
424
425 After:
426
427 has_many :things, :conditions => proc { "foo = #{bar}" }
428
429 Inside the proc, 'self' is the object which is the owner of the association, unless you are
430 eager loading the association, in which case 'self' is the class which the association is within.
431
432 You can have any "normal" conditions inside the proc, so the following will work too:
433
434 has_many :things, :conditions => proc { ["foo = ?", bar] }
435
436 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
437 'record' to get the record being inserted or deleted. This is now passed as an argument to
438 the proc.
439
440 * Added ActiveRecord::Base#has_secure_password (via ActiveModel::SecurePassword) to encapsulate dead-simple password usage with BCrypt encryption and salting [DHH]. Example:
441
442 # Schema: User(name:string, password_digest:string, password_salt:string)
443 class User < ActiveRecord::Base
444 has_secure_password
445 end
446
447 user = User.new(:name => "david", :password => "", :password_confirmation => "nomatch")
448 user.save # => false, password required
449 user.password = "mUc3m00RsqyRe"
450 user.save # => false, confirmation doesn't match
451 user.password_confirmation = "mUc3m00RsqyRe"
452 user.save # => true
453 user.authenticate("notright") # => false
454 user.authenticate("mUc3m00RsqyRe") # => user
455 User.find_by_name("david").try(:authenticate, "notright") # => nil
456 User.find_by_name("david").try(:authenticate, "mUc3m00RsqyRe") # => user
457
458
459 * When a model is generated add_index is added by default for belongs_to or references columns
460
461 rails g model post user:belongs_to will generate the following:
462
463 class CreatePosts < ActiveRecord::Migration
464 def up
465 create_table :posts do |t|
466 t.belongs_to :user
467 t.timestamps
468 end
469
470 add_index :posts, :user_id
471 end
472
473 def down
474 drop_table :posts
475 end
476 end
477
478 *Santiago Pastorino*
479
480 * Setting the id of a belongs_to object will update the reference to the
481 object. [#2989 state:resolved]
482 * ActiveRecord::Base#dup and ActiveRecord::Base#clone semantics have changed
483 to closer match normal Ruby dup and clone semantics.
484 * Calling ActiveRecord::Base#clone will result in a shallow copy of the record,
485 including copying the frozen state. No callbacks will be called.
486 * Calling ActiveRecord::Base#dup will duplicate the record, including calling
487 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.
488 * Migrations can be defined as reversible, meaning that the migration system
489 will figure out how to reverse your migration. To use reversible migrations, just define the "change" method. For example:
490 class MyMigration < ActiveRecord::Migration
491 def change
492 create_table(:horses) do
493 t.column :content, :text
494 t.column :remind_at, :datetime
495 end
496 end
497 end
498
499 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.
500 * Migrations should use instance methods rather than class methods:
501 class FooMigration < ActiveRecord::Migration
502 def up
503 ...
504 end
505 end
506
507 *Aaron Patterson*
508
509 * has_one maintains the association with separate after_create/after_update instead
510 of a single after_save. *fxn*
511
512 * The following code:
513
514 Model.limit(10).scoping { Model.count }
515
516 now generates the following SQL:
517
518 SELECT COUNT(*) FROM models LIMIT 10
519
520 This may not return what you want. Instead, you may with to do something
521 like this:
522

528 ## Rails 3.0.7 (April 18, 2011) ##
529
530 * Destroying records via nested attributes works independent of reject_if LH #6006 *Durran Jordan*
531
532 * Delegate any? and many? to Model.scoped for consistency *Andrew White*
533
534 * Quote the ORDER BY clause in batched finds - fixes #6620 *Andrew White*
535
536 * Change exists? so records are not instantiated - fixes #6127. This prevents after_find
537 and after_initialize callbacks being triggered when checking for record existence.
538 *Andrew White*
539
540 * Fix performance bug with attribute accessors which only occurred on Ruby 1.8.7, and ensure we
541 cache type-casted values when the column returned from the db contains non-standard chars.
542 *Jon Leighton*
543
544 * Fix a performance regression introduced here 86acbf1cc050c8fa8c74a10c735e467fb6fd7df8
545 related to read_attribute method *Stian Grytøyr*
546
547
548 ## Rails 3.0.6 (April 5, 2011) ##
549
550 * Un-deprecate reorder method *Sebastian Martinez*
551
552 * Extensions are applied when calling +except+ or +only+ on relations.
553 Thanks to Iain Hecker.
554
555 * Schemas set in set_table_name are respected by the mysql adapter. LH #5322
556
557 * Fixed a bug when empty? was called on a grouped Relation that wasn't loaded.
558 LH #5829
559
560 * Reapply extensions when using except and only. Thanks Iain Hecker.
561
562 * Binary data is escaped when being inserted to SQLite3 Databases. Thanks
563 Naruse!
564
565
566 ## Rails 3.0.5 (February 26, 2011) ##
567
568 * Model.where(:column => 1).where(:column => 2) will always produce an AND
569 query.
570 *Aaron Patterson*
571
572 * Deprecated support for interpolated association conditions in the form of :conditions => 'foo = #{bar}'.
573
574 Instead, you should use a proc, like so:
575
576 Before:
577
578 has_many :things, :conditions => 'foo = #{bar}'
579
580 After:
581
582 has_many :things, :conditions => proc { "foo = #{bar}" }
583
584 Inside the proc, 'self' is the object which is the owner of the association, unless you are
585 eager loading the association, in which case 'self' is the class which the association is within.
586
587 You can have any "normal" conditions inside the proc, so the following will work too:
588
589 has_many :things, :conditions => proc { ["foo = ?", bar] }
590
591 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
592 'record' to get the record being inserted or deleted. This is now passed as an argument to
593 the proc.
594
595 *Jon Leighton*
596
597
598 ## Rails 3.0.4 (February 8, 2011) ##
599
600 * Added deprecation warning for has_and_belongs_to_many associations where the join table has
601 additional attributes other than the keys. Access to these attributes is removed in 3.1.
602 Please use has_many :through instead. *Jon Leighton*
603
604
605 ## Rails 3.0.3 (November 16, 2010) ##
606
607 * Support find by class like this: Post.where(:name => Post)
608
609
610 ## Rails 3.0.2 (November 15, 2010) ##
611
612 * Dramatic speed increase (see: http://engineering.attinteractive.com/2010/10/arel-two-point-ohhhhh-yaaaaaa/) *Aaron Patterson*
613
614 * reorder is deprecated in favor of except(:order).order(...) *Santiago Pastorino*
615
616 * except is now AR public API
617
618 Model.order('name').except(:order).order('salary')
619
620 generates:
621
622 SELECT * FROM models ORDER BY salary
623
624 *Santiago Pastorino*
625
626 * The following code:
627
628 Model.limit(10).scoping { Model.count }
629
630 now generates the following SQL:
631
632 SELECT COUNT(*) FROM models LIMIT 10
633
634 This may not return what you want. Instead, you may with to do something
635 like this:
636
637 Model.limit(10).scoping { Model.all.size }
638
639 *Aaron Patterson*
640
641
642 ## Rails 3.0.1 (October 15, 2010) ##
643
644 * Introduce a fix for CVE-2010-3993
645
646
647 ## Rails 3.0.0 (August 29, 2010) ##
648
649 * Changed update_attribute to not run callbacks and update the record directly in the database *Neeraj Singh*
650
651 * Add scoping and unscoped as the syntax to replace the old with_scope and with_exclusive_scope *José Valim*
652
653 * New rake task, db:migrate:status, displays status of migrations #4947 *Kevin Skoglund*
654
655 * select and order for ActiveRecord now always concatenate nested calls. Use reorder if you want the original order to be overwritten *Santiago Pastorino*
656
657 * PostgreSQL: ensure the database time zone matches Ruby's time zone #4895 *Aaron Patterson*
658
659 * Fixed that ActiveRecord::Base.compute_type would swallow NoMethodError #4751 *Andrew Bloomgarden, Andrew White*
660
661 * Add index length support for MySQL. #1852 *Emili Parreno, Pratik Naik*
662
663 Example:
664
665 add_index(:accounts, :name, :name => 'by_name', :length => 10)
666 => CREATE INDEX by_name ON accounts(name(10))
667
668 add_index(:accounts, [:name, :surname], :name => 'by_name_surname', :length => {:name => 10, :surname => 15})
669 => CREATE INDEX by_name_surname ON accounts(name(10), surname(15))
670
671 * find_or_create_by_attr(value, ...) works when attr is protected. #4457 *Santiago Pastorino, Marc-André Lafortune*
672
673 * New callbacks: after_commit and after_rollback. Do expensive operations like image thumbnailing after_commit instead of after_save. #2991 *Brian Durand*
674
675 * 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*
676
677 * 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*
678
679 * PostgreSQL: drop support for old postgres driver. Use pg 0.9.0 or later. *Jeremy Kemper*
680
681 * Observers can prevent records from saving by returning false, just like before_save and friends. #4087 *Mislav Marohnić*
682
683 * Add Relation extensions. *Pratik Naik*
684
685 users = User.where(:admin => true).extending(User::AdminPowers)
686
687 latest_users = User.order('created_at DESC') do
688 def posts_count
689 Post.count(:user_id => to_a.map(&:id))
690 end
691 end
692
693 * To prefix the table names of all models in a module, define self.table_name_prefix on the module. #4032 *Andrew White*
694
695 * 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*
696
697 * 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*
698
699 * Allow relations to be used as scope.
700
701 class Item
702 scope :red, where(:colour => 'red')
703 end
704
705 Item.red.limit(10) # Ten red items
706
707 * Rename named_scope to scope. *Pratik Naik*
708
709 * Changed ActiveRecord::Base.store_full_sti_class to be true by default reflecting the previously announced Rails 3 default *DHH*
710
711 * Add Relation#except. *Pratik Naik*
712
713 one_red_item = Item.where(:colour => 'red').limit(1)
714 all_items = one_red_item.except(:where, :limit)
715
716 * Add Relation#delete_all. *Pratik Naik*
717
718 Item.where(:colour => 'red').delete_all
719
720 * Add Model.having and Relation#having. *Pratik Naik*
721
722 Developer.group("salary").having("sum(salary) > 10000").select("salary")
723
724 * Add Relation#count. *Pratik Naik*
725
726 legends = People.where("age > 100")
727 legends.count
728 legends.count(:age, :distinct => true)
729 legends.select('id').count
730
731 * Add Model.readonly and association_collection#readonly finder method. *Pratik Naik*
732
733 Post.readonly.to_a # Load all posts in readonly mode
734 @user.items.readonly(false).to_a # Load all the user items in writable mode
735
736 * Add .lock finder method *Pratik Naik*
737
738 User.lock.where(:name => 'lifo').to_a
739
740 old_items = Item.where("age > 100")
741 old_items.lock.each {|i| .. }
742
743 * Add Model.from and association_collection#from finder methods *Pratik Naik*
744
745 user = User.scoped
746 user.select('*').from('users, items')
747
748 * Add relation.destroy_all *Pratik Naik*
749
750 old_items = Item.where("age > 100")
751 old_items.destroy_all
752
753 * Add relation.exists? *Pratik Naik*
754
755 red_items = Item.where(:colours => 'red')
756 red_items.exists?
757 red_items.exists?(1)
758
759 * Add find(ids) to relations. *Pratik Naik*
760
761 old_users = User.order("age DESC")
762 old_users.find(1)
763 old_users.find(1, 2, 3)
764
765 * Add new finder methods to association collection. *Pratik Naik*
766
767 class User < ActiveRecord::Base
768 has_many :items
769 end
770
771 user = User.first
772 user.items.where(:items => {:colour => 'red'})
773 user.items.select('items.id')
774
775 * Add relation.reload to force reloading the records. *Pratik Naik*
776
777 topics = Topic.scoped
778 topics.to_a # force load
779 topics.first # returns a cached record
780 topics.reload
781 topics.first # Fetches a new record from the database
782
783 * Rename Model.conditions and relation.conditions to .where. *Pratik Naik*
784
785 Before :
786 User.conditions(:name => 'lifo')
787 User.select('id').conditions(["age > ?", 21])
788
789 Now :
790 User.where(:name => 'lifo')
791 User.select('id').where(["age > ?", 21])
792
793 * Add Model.select/group/order/limit/joins/conditions/preload/eager_load class methods returning a lazy relation. *Pratik Naik*
794
795 Examples :
796
797 posts = Post.select('id).order('name') # Returns a lazy relation
798 posts.each {|p| puts p.id } # Fires "select id from posts order by name"
799
800 * Model.scoped now returns a relation if invoked without any arguments. *Pratik Naik*
801
802 Example :
803
804 posts = Post.scoped
805 posts.size # Fires "select count(*) from posts" and returns the count
806 posts.each {|p| puts p.name } # Fires "select * from posts" and loads post objects
807
808 * Association inverses for belongs_to, has_one, and has_many. Optimization to reduce database queries. #3533 *Murray Steele*
809
810 # post.comments sets each comment's post without needing to :include
811 class Post < ActiveRecord::Base
812 has_many :comments, :inverse_of => :post
813 end
814
815 * MySQL: add_ and change_column support positioning. #3286 *Ben Marini*
816
817 * Reset your Active Record counter caches with the reset_counter_cache class method. #1211 *Mike Breen, Gabe da Silveira*
818
819 * Remove support for SQLite 2. Please upgrade to SQLite 3+ or install the plugin from git://github.com/rails/sqlite2_adapter.git *Pratik Naik*
820
821 * PostgreSQL: XML datatype support. #1874 *Leonardo Borges*
822
823 * 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*
824
825 * SQLite: drop support for 'dbfile' option in favor of 'database.' #2363 *Paul Hinze, Jeremy Kemper*
826
827 * Added :primary_key option to belongs_to associations. #765 *Szymon Nowak, Philip Hallstrom, Noel Rocha*
828 # employees.company_name references companies.name
829 Employee.belongs_to :company, :primary_key => 'name', :foreign_key => 'company_name'
830
831 * Implement #many? for NamedScope and AssociationCollection using #size. #1500 *Chris Kampmeier*
832
833 * Added :touch option to belongs_to associations that will touch the parent record when the current record is saved or destroyed *DHH*
834
835 * Added ActiveRecord::Base#touch to update the updated_at/on attributes (or another specified timestamp) with the current time *DHH*
836
837
838 ## 2.3.2 Final (March 15, 2009) ##

841
842 * Added that ActiveRecord::Base.exists? can be called with no arguments #1817 *Scott Taylor*
843
844 * Add Support for updating deeply nested models from a single form. #1202 *Eloy Duran*
845
846 class Book < ActiveRecord::Base
847 has_one :author
848 has_many :pages
849
850 accepts_nested_attributes_for :author, :pages
851 end
852
853 * Make after_save callbacks fire only if the record was successfully saved. #1735 *Michael Lovitt*
854
855 Previously the callbacks would fire if a before_save cancelled saving.
856
857 * Support nested transactions using database savepoints. #383 *Jonathan Viney, Hongli Lai*
858
859 * Added dynamic scopes ala dynamic finders #1648 *Yaroslav Markin*
860
861 * Fixed that ActiveRecord::Base#new_record? should return false (not nil) for existing records #1219 *Yaroslav Markin*
862
863 * I18n the word separator for error messages. Introduces the activerecord.errors.format.separator translation key. #1294 *Akira Matsuda*
864
865 * Add :having as a key to find and the relevant associations. *Emilio Tagua*
866
867 * Added default_scope to Base #1381 [Paweł Kondzior]. Example:
868
869 class Person < ActiveRecord::Base
870 default_scope :order => 'last_name, first_name'
871 end
872
873 class Company < ActiveRecord::Base
874 has_many :people
875 end
876
877 Person.all # => Person.find(:all, :order => 'last_name, first_name')
878 Company.find(1).people # => Person.find(:all, :order => 'last_name, first_name', :conditions => { :company_id => 1 })
879
880
881 ## 2.2.1 RC2 (November 14th, 2008) ##
882
883 * Ensure indices don't flip order in schema.rb #1266 *Jordi Bunster*

886
887
888 ## 2.2.0 RC1 (October 24th, 2008) ##
889
890 * Skip collection ids reader optimization if using :finder_sql *Jeremy Kemper*
891
892 * Add Model#delete instance method, similar to Model.delete class method. #1086 *Hongli Lai (Phusion)*
893
894 * MySQL: cope with quirky default values for not-null text columns. #1043 *Frederick Cheung*
895
896 * Multiparameter attributes skip time zone conversion for time-only columns [#1030 state:resolved] *Geoff Buesing*
897
898 * Base.skip_time_zone_conversion_for_attributes uses class_inheritable_accessor, so that subclasses don't overwrite Base [#346 state:resolved] *Emilio Tagua*
899
900 * Added find_last_by dynamic finder #762 *Emilio Tagua*
901
902 * Internal API: configurable association options and build_association method for reflections so plugins may extend and override. #985 *Hongli Lai (Phusion)*
903
904 * Changed benchmarks to be reported in milliseconds *David Heinemeier Hansson*
905
906 * Connection pooling. #936 *Nick Sieger*
907
908 * Merge scoped :joins together instead of overwriting them. May expose scoping bugs in your code! #501 *Andrew White*
909
910 * 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*
911
912 * Transactional migrations for databases which support them. #834 *divoxx, Adam Wiggins, Tarmo Tänav*
913
914 * Set config.active_record.timestamped_migrations = false to have migrations with numeric prefix instead of UTC timestamp. #446. *Andrew Stone, Nik Wakelin*
915
916 * change_column_default preserves the not-null constraint. #617 *Tarmo Tänav*
917
918 * Fixed that create database statements would always include "DEFAULT NULL" (Nick Sieger) *#334*
919
920 * Add :tokenizer option to validates_length_of to specify how to split up the attribute string. #507. [David Lowenfels] Example :
921
922 \# Ensure essay contains at least 100 words.
923 validates_length_of :essay, :minimum => 100, :too_short => "Your essay must be at least %d words."), :tokenizer => lambda {|str| str.scan(/\w+/) }
924
925 * Allow conditions on multiple tables to be specified using hash. [Pratik Naik]. Example:
926
927 User.all :joins => :items, :conditions => { :age => 10, :items => { :color => 'black' } }
928 Item.first :conditions => { :items => { :color => 'red' } }
929
930 * Always treat integer :limit as byte length. #420 *Tarmo Tänav*
931
932 * Partial updates don't update lock_version if nothing changed. #426 *Daniel Morrison*
933
934 * Fix column collision with named_scope and :joins. #46 *Duncan Beevers, Mark Catley*
935
936 * db:migrate:down and :up update schema_migrations. #369 *Michael Raidel, RaceCondition*
937
938 * PostgreSQL: support :conditions => [':foo::integer', { :foo => 1 }] without treating the ::integer typecast as a bind variable. *Tarmo Tänav*
939
940 * MySQL: rename_column preserves column defaults. #466 *Diego Algorta*
941
942 * Add :from option to calculations. #397 *Ben Munat*
943
944 * Add :validate option to associations to enable/disable the automatic validation of associated models. Resolves #301. *Jan De Poorter*
945
946 * PostgreSQL: use 'INSERT ... RETURNING id' for 8.2 and later. *Jeremy Kemper*
947
948 * Added SQL escaping for :limit and :offset in MySQL *Jonathan Wiess*
949
950
951 ## 2.1.0 (May 31st, 2008) ##
952
953 * Add ActiveRecord::Base.sti_name that checks ActiveRecord::Base#store_full_sti_class? and returns either the full or demodulized name. *Rick Olson*
954
955 * Add first/last methods to associations/named_scope. Resolved #226. *Ryan Bates*
956
957 * Added SQL escaping for :limit and :offset #288 *Aaron Bedra, Steven Bristol, Jonathan Wiess*
958
959 * Added first/last methods to associations/named_scope. Resolved #226. *Ryan Bates*
960
961 * Ensure hm:t preloading honours reflection options. Resolves #137. *Frederick Cheung*
962
963 * Added protection against duplicate migration names (Aslak Hellesøy) *#112*
964
965 * 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*
966
967 * 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*
968
969 * Added change_table for migrations (Jeff Dean) [#71]. Example:
970
971 change_table :videos do |t|
972 t.timestamps # adds created_at, updated_at
973 t.belongs_to :goat # adds goat_id integer
974 t.string :name, :email, :limit => 20 # adds name and email both with a 20 char limit
975 t.remove :name, :email # removes the name and email columns
976 end
977
978 * Fixed has_many :through .create with no parameters caused a "can't dup NilClass" error (Steven Soroka) *#85*
979
980 * Added block-setting of attributes for Base.create like Base.new already has (Adam Meehan) *#39*
981
982 * Fixed that pessimistic locking you reference the quoted table name (Josh Susser) *#67*
983
984 * Fixed that change_column should be able to use :null => true on a field that formerly had false [Nate Wiger] *#26*
985
986 * Added that the MySQL adapter should map integer to either smallint, int, or bigint depending on the :limit just like PostgreSQL *David Heinemeier Hansson*
987
988 * Change validates_uniqueness_of :case_sensitive option default back to true (from [9160]). Love your database columns, don't LOWER them. *Rick Olson*
989
990 * Add support for interleaving migrations by storing which migrations have run in the new schema_migrations table. Closes #11493 *Jordi Bunster*
991
992 * ActiveRecord::Base#sum defaults to 0 if no rows are returned. Closes #11550 *Kamal Fariz Mahyuddin*
993
994 * Ensure that respond_to? considers dynamic finder methods. Closes #11538. *James Mead*
995
996 * Ensure that save on parent object fails for invalid has_one association. Closes #10518. *Pratik Naik*
997
998 * Remove duplicate code from associations. *Pratik Naik*
999
1000 * Refactor HasManyThroughAssociation to inherit from HasManyAssociation. Association callbacks and <association>_ids= now work with hm:t. #11516 *Ruy Asan*
1001
1002 * Ensure HABTM#create and HABTM#build do not load entire association. *Pratik Naik*
1003
1004 * Improve documentation. *Xavier Noria, Jack Danger Canty, leethal*
1005
1006 * Tweak ActiveRecord::Base#to_json to include a root value in the returned hash: {"post": {"title": ...}} *Rick Olson*
1007
1008 Post.find(1).to_json # => {"title": ...}
1009 config.active_record.include_root_in_json = true
1010 Post.find(1).to_json # => {"post": {"title": ...}}
1011
1012 * Add efficient #include? to AssociationCollection (for has_many/has_many :through/habtm). *stopdropandrew*
1013
1014 * PostgreSQL: create_ and drop_database support. #9042 *ez, pedz, Nick Sieger*
1015
1016 * Ensure that validates_uniqueness_of works with with_scope. Closes #9235. *Nik Wakelin, cavalle*
1017

1317 belongs_to :article, :counter_cache => :comments_count
1318 end
1319
1320 class Article < ActiveRecord::Base
1321 attr_readonly :approved_comments_count

1339
1340 * Added ActiveRecord::Base#to_json/from_json *David Heinemeier Hansson, Cheah Chu Yeow*
1341
1342 * Added ActiveRecord::Base#from_xml [David Heinemeier Hansson]. Example:

1344 xml = "<person><name>David</name></person>"
1345 Person.new.from_xml(xml).name # => "David"
1346
1347 * Define dynamic finders as real methods after first usage. *bscofield*

1359 * Extract Firebird, FrontBase, and OpenBase adapters into gems. #9508, #9509, #9510 *Jeremy Kemper*
1360
1361 * RubyGem database adapters: expects a gem named activerecord-<database>-adapter with active_record/connection_adapters/<database>_adapter.rb in its load path. *Jeremy Kemper*
1362
1363 * Fixed that altering join tables in migrations would fail w/ sqlite3 #7453 *TimoMihaljov/brandon*

1387 * Don't clobber includes passed to has_many.count *Jack Danger Canty*
1388
1389 * Make sure has_many uses :include when counting *Jack Danger Canty*
1390
1391 * Change the implementation of ActiveRecord's attribute reader and writer methods *Michael Koziarski*
1392 - 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.
1393 * Perform a deep #dup on query cache results so that modifying activerecord attributes does not modify the cached attributes. *Rick Olson*
1394
1395 \# Ensure that has_many :through associations use a count query instead of loading the target when #size is called. Closes #8800 [Pratik Naik]
1396 * Added :unless clause to validations #8003 [monki]. Example:
1397
1398 def using_open_id?
1399 !identity_url.blank?
1400 end
1401
1402 validates_presence_of :identity_url, :if => using_open_id?
1403 validates_presence_of :username, :unless => using_open_id?
1404 validates_presence_of :password, :unless => using_open_id?
1405
1406 * Fix #count on a has_many :through association so that it recognizes the :uniq option. Closes #8801 *Pratik Naik*
1407
1408 * Fix and properly document/test count(column_name) usage. Closes #8999 *Pratik Naik*
1409
1410 * Remove deprecated count(conditions=nil, joins=nil) usage. Closes #8993 *Pratik Naik*
1411
1412 * Change belongs_to so that the foreign_key assumption is taken from the association name, not the class name. Closes #8992 *Josh Susser*

1477
1478 * Optimistic locking: revert the lock version when an update fails. #7840 *plang*
1479
1480 * Migrations: add_column supports custom column types. #7742 *jsgarvin, Theory*
1481
1482 * Load database adapters on demand. Eliminates config.connection_adapters and RAILS_CONNECTION_ADAPTERS. Add your lib directory to the $LOAD_PATH and put your custom adapter in lib/active_record/connection_adapters/adaptername_adapter.rb. This way you can provide custom adapters as plugins or gems without modifying Rails. *Jeremy Kemper*
1483
1484 * Ensure that associations with :dependent => :delete_all respect :conditions option. Closes #8034 *Jack Danger Canty, Josh Peek, Rick Olson*

1504 * Add documentation caveat about when to use count_by_sql. *fearoffish*
1505
1506 * Enhance documentation for increment_counter and decrement_counter. *fearoffish*
1507
1508 * Provide brief introduction to what optimistic locking is. *fearoffish*
1509
1510 * Add documentation for :encoding option to mysql adapter. *marclove*
1511
1512 * Added short-hand declaration style to migrations (inspiration from Sexy Migrations, http://errtheblog.com/post/2381) [David Heinemeier Hansson]. Example:
1513
1514 create_table "products" do |t|
1515 t.column "shop_id", :integer
1516 t.column "creator_id", :integer
1517 t.column "name", :string, :default => "Untitled"
1518 t.column "value", :string, :default => "Untitled"
1519 t.column "created_at", :datetime
1520 t.column "updated_at", :datetime
1521 end
1522
1523 ...can now be written as:
1524
1525 create_table :products do |t|
1526 t.integer :shop_id, :creator_id
1527 t.string :name, :value, :default => "Untitled"
1528 t.timestamps
1529 end
1530
1531 * 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*
1532
1533 * Improve performance of calling .create on has_many :through associations. *evan*
1534
1535 * Improved cloning performance by relying less on exception raising #8159 *Blaine*

1538
1539 * Added yielding of Builder instance for ActiveRecord::Base#to_xml calls *David Heinemeier Hansson*
1540

1544
1545 * SQLite: binary escaping works with $KCODE='u'. #7862 *tsuka*
1546
1547 * Base#to_xml supports serialized attributes. #7502 *jonathan*
1548
1549 * Base.update_all :order and :limit options. Useful for MySQL updates that must be ordered to avoid violating unique constraints. *Jeremy Kemper*
1550
1551 * 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*
1552
1553 * 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*
1554
1555 * 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*
1556
1557 * 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*
1558
1559 * Allow a polymorphic :source for has_many :through associations. Closes #7143 *protocool*
1560
1561 * Consistent public/protected/private visibility for chained methods. #7813 *Dan Manges*
1562

1565 * Consistently quote primary key column names. #7763 *toolmantim*
1566
1567 * Fixtures: fix YAML ordered map support. #2665 *Manuel Holtgrewe, nfbuckley*
1568
1569 * DateTimes assume the default timezone. #7764 *Geoff Buesing*
1570
1571 * Sybase: hide timestamp columns since they're inherently read-only. #7716 *Mike Joyce*
1572
1573 * Oracle: overflow Time to DateTime. #7718 *Michael Schoen*
1574
1575 * PostgreSQL: don't use async_exec and async_query with postgres-pr. #7727, #7762 *flowdelic, toolmantim*
1576
1577 * Fix has_many :through << with custom foreign keys. #6466, #7153 *naffis, Rich Collins*
1578
1579 * Test DateTime native type in migrations, including an edge case with dates
1580 during calendar reform. #7649, #7724 [fedot, Geoff Buesing]
1581 * SQLServer: correctly schema-dump tables with no indexes or descending indexes. #7333, #7703 *Jakob Skjerning, Tom Ward*
1582
1583 * SQLServer: recognize real column type as Ruby float. #7057 *sethladd, Tom Ward*
1584
1585 * Added fixtures :all as a way of loading all fixtures in the fixture directory at once #7214 *Manfred Stienstra*
1586
1587 * Added database connection as a yield parameter to ActiveRecord::Base.transaction so you can manually rollback [David Heinemeier Hansson]. Example:
1588
1589 transaction do |transaction|
1590 david.withdrawal(100)
1591 mary.deposit(100)
1592 transaction.rollback! # rolls back the transaction that was otherwise going to be successful
1593 end
1594
1595 * Made increment_counter/decrement_counter play nicely with optimistic locking, and added a more general update_counters method *Jamis Buck*
1596
1597 * 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*
1598 Task.cache { Task.find(1); Task.find(1) } # => 1 query
1599
1600 * 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*
1601
1602 * Oracle: fix lob and text default handling. #7344 *gfriedrich, Michael Schoen*
1603
1604 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
1605
1606 * MySQL: blob and text columns may not have defaults in 5.x. Update fixtures schema for strict mode. #6695 *Dan Kubb*
1607
1608 * 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*
1609
1610 * MySQL: SET SQL_AUTO_IS_NULL=0 so 'where id is null' doesn't select the last inserted id. #6778 *Jonathan Viney, timc*
1611
1612 * Use Date#to_s(:db) for quoted dates. #7411 *Michael Schoen*
1613
1614 * Don't create instance writer methods for class attributes. Closes #7401 *Rick Olson*
1615
1616 * Docs: validations examples. #7343 *zackchandler*
1617
1618 * Add missing tests ensuring callbacks work with class inheritance. Closes #7339 *sandofsky*
1619
1620 * Fixtures use the table name and connection from set_fixture_class. #7330 *Anthony Eden*
1621
1622 * Remove useless code in #attribute_present? since 0 != blank?. Closes #7249 *Josh Susser*
1623
1624 * Fix minor doc typos. Closes #7157 *Josh Susser*
1625
1626 * Fix incorrect usage of #classify when creating the eager loading join statement. Closes #7044 *Josh Susser*

1632 * Make sure sqlite3 driver closes open connections on disconnect *Rob Rasmussen*
1633
1634 * [DOC] clear up some ambiguity with the way has_and_belongs_to_many creates the default join table name. #7072 *Jeremy McAnally*
1635
1636 * change_column accepts :default => nil. Skip column options for primary keys. #6956, #7048 *Dan Manges, Jeremy Kemper*
1637
1638 * 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*
1639
1640 * Oracle: create_table takes a :sequence_name option to override the 'tablename_seq' default. #7000 *Michael Schoen*
1641
1642 * MySQL: retain SSL settings on reconnect. #6976 *randyv2*
1643
1644 * Apply scoping during initialize instead of create. Fixes setting of foreign key when using find_or_initialize_by with scoping. *Cody Fauser*
1645
1646 * SQLServer: handle [quoted] table names. #6635 *rrich*
1647
1648 * acts_as_nested_set works with single-table inheritance. #6030 *Josh Susser*
1649
1650 * PostgreSQL, Oracle: correctly perform eager finds with :limit and :order. #4668, #7021 *eventualbuddha, Michael Schoen*
1651
1652 * Pass a range in :conditions to use the SQL BETWEEN operator. #6974 *Dan Manges*
1653 Student.find(:all, :conditions => { :grade => 9..12 })
1654
1655 * Fix the Oracle adapter for serialized attributes stored in CLOBs. Closes #6825 *mschoen, tdfowler*
1656
1657 * [DOCS] Apply more documentation for ActiveRecord Reflection. Closes #4055 *Robby Russell*
1658
1659 * [DOCS] Document :allow_nil option of #validate_uniqueness_of. Closes #3143 *Caio Chassot*
1660
1661 * Bring the sybase adapter up to scratch for 1.2 release. *jsheets*
1662
1663 * Rollback new_record? and id when an exception is raised in a save callback. #6910 *Ben Curren, outerim*
1664
1665 * Pushing a record on an association collection doesn't unnecessarily load all the associated records. *Obie Fernandez, Jeremy Kemper*
1666
1667 * Oracle: fix connection reset failure. #6846 *leonlleslie*
1668
1669 * Subclass instantiation doesn't try to explicitly require the corresponding subclass. #6840 *leei, Jeremy Kemper*
1670
1671 * 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*
1672
1673 * 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*
1674
1675 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
1676
1677 * Add AssociationCollection#create! to be consistent with AssociationCollection#create when dealing with a foreign key that is a protected attribute *Cody Fauser*
1678
1679 * 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*
1680
1681 * Change fixture_path to a class inheritable accessor allowing test cases to have their own custom set of fixtures. #6672 *Zach Dennis*
1682
1683 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
1684
1685 * Simplify query_attribute by typecasting the attribute value and checking whether it's nil, false, zero or blank. #6659 *Jonathan Viney*
1686
1687 * 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*
1688
1689 * Run validations in the order they were declared. #6657 *obrie*
1690
1691 * 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*
1692
1693 * Simplify association proxy implementation by factoring construct_scope out of method_missing. #6643 *martin*
1694
1695 * Oracle: automatically detect the primary key. #6594 *vesaria, Michael Schoen*
1696
1697 * 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*
1698
1699 * Don't inspect unloaded associations. #2905 *lmarlow*

1712 find(:all, :conditions => { :topic_id => [1, 2, 3], :last_read => nil }
1713
1714 * 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*
1715
1716 * SQLite: fix calculations workaround, remove count(distinct) query rewrite, cleanup test connection scripts. *Jeremy Kemper*
1717
1718 * SQLite: count(distinct) queries supported in >= 3.2.6. #6544 *Bob Silva*

1725
1726 * 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*
1727
1728 * Make add_column use the options hash with the Sqlite Adapter. Closes #6464 *obrie*
1729
1730 * Document other options available to migration's add_column. #6419 *grg*
1731
1732 * MySQL: all_hashes compatibility with old MysqlRes class. #6429, #6601 *Jeremy Kemper*
1733

1737
1738 * Restore eager condition interpolation, document it's differences *Rick Olson*
1739
1740 * 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*
1741
1742 * Add #delete support to has_many :through associations. Closes #6049 *Martin Landers*
1743
1744 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
1745
1746 * 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*
1747
1748 * 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*
1749
1750 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*
1751
1752 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
1753
1754 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
1755
1756 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
1757
1758 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
1759
1760 * 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*
1761
1762 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
1763
1764 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*
1765
1766 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*

1775
1776 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
1777
1778 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
1779
1780 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
1781
1782 * 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*
1783
1784 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
1785
1786 * Document validates_presences_of behavior with booleans: you probably want validates_inclusion_of :attr, :in => [true, false]. #2253 *Bob Silva*
1787
1788 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
1789
1790 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
1791
1792 * Deprecation: update docs. #5998 *Jakob Skjerning, Kevin Clark*
1793
1794 * Add some XmlSerialization tests for ActiveRecord *Rick Olson*
1795
1796 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
1797
1798 * Tighten rescue clauses. #5985 *james@grayproductions.net*
1799
1800 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*

1802 * 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*
1803
1804 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
1805
1806 * 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*

1817
1818 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
1819
1820 * 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*
1821
1822 * 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*
1823
1824 # Create a tagging to associate the post and tag.
1825 post.tags << Tag.find_by_name('old')
1826 post.tags.create! :name => 'general'
1827
1828 # Would have been:
1829 post.taggings.create!(:tag => Tag.find_by_name('finally')
1830 transaction do
1831 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
1832 end

1839 Example: Invoice::Lineitem is given table name invoice_lineitems
1840
1841 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
1842 # people_active_last_name_index, people_active_deactivated_at_index
1843 add_index :people, [:active, :last_name]
1844 add_index :people, [:active, :deactivated_at]
1845 remove_index :people, [:active, :last_name]
1846 remove_index :people, [:active, :deactivated_at]
1847
1848 WARNING: backward-incompatibility. Multicolumn indexes created before this
1849 revision were named using the first column name only. Now they're uniquely
1850 named using all indexed columns.
1851
1852 To remove an old multicolumn index, remove_index :table_name, :first_column
1853
1854 * Fix for deep includes on the same association. *richcollins@gmail.com*
1855
1856 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
1857
1858 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
1859
1860 * Document find's :from option. Closes #5762. *andrew@redlinesoftware.com*
1861
1862 * 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*
1863
1864 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
1865
1866 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
1867
1868 * Add documentation for how to disable timestamps on a per model basis. Closes #5684. *matt@mattmargolis.net Marcel Molina Jr.*
1869
1870 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
1871
1872 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
1873
1874 * Formally deprecate the deprecated finders. *Michael Koziarski*

1884 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
1885

1887
1888 assert (Topic.exists?(:author_name => "David"))
1889 assert (Topic.exists?(:author_name => "Mary", :approved => true))
1890 assert (Topic.exists?(["parent_id = ?", 1]))
1891

1897
1898 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
1899
1900 * Allow #count through a has_many association to accept :include. *Dan Peterson*
1901

1913
1914 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*

1916 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
1917
1918 * Update callbacks documentation. #3970 *Robby Russell <robby@planetargon.com>*
1919
1920 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
1921
1922 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
1923
1924 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
1925
1926 * 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*
1927
1928 * 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*
1929
1930 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
1931
1932 * Minor tweak to improve performance of ActiveRecord::Base#to_param.
1933
1934 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
1935
1936 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
1937
1938 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
1939
1940 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
1941
1942 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
1943
1944 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
1945
1946 * 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*
1947 # Obtain an exclusive lock on person 1 so we can safely increment visits.
1948 Person.transaction do
1949 # select * from people where id=1 for update
1950 person = Person.find(1, :lock => true)
1951 person.visits += 1
1952 person.save!
1953 end
1954
1955 * 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*
1956
1957 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
1958
1959 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
1960
1961 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
1962
1963 * 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*
1964
1965 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
1966
1967 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
1968
1969 ...is the same as:
1970 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
1971
1972 This makes it easier to pass in the options from a form or otherwise outside.
1973

1983 * Fixed that count distinct should use the selected column even when using :include #5251 *anna@wota.jp*
1984
1985 * 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*
1986
1987 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
1988
1989 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
1990
1991 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
1992 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
1993 Foo.find(:first, :conditions => ['bar_id = ?', bar])
1994
1995 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
1996
1997 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
1998
1999 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*

2017
2018 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2019
2020 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2021
2022 * 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*

2197
2198 * Make add_column use the options hash with the Sqlite Adapter. Closes #6464 *obrie*
2199
2200 * Document other options available to migration's add_column. #6419 *grg*
2201
2202 * MySQL: all_hashes compatibility with old MysqlRes class. #6429, #6601 *Jeremy Kemper*
2203
2204 * Fix has_many :through to add the appropriate conditions when going through an association using STI. Closes #5783. *Jonathan Viney*
2205
2206 * fix select_limited_ids_list issues in postgresql, retain current behavior in other adapters *Rick Olson*
2207
2208 * Restore eager condition interpolation, document it's differences *Rick Olson*
2209
2210 * 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*
2211
2212 * Add #delete support to has_many :through associations. Closes #6049 *Martin Landers*
2213
2214 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
2215
2216 * 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*
2217
2218 * 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*
2219
2220 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*
2221
2222 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
2223
2224 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
2225
2226 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
2227
2228 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
2229
2230 * 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*
2231
2232 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
2233
2234 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*
2235
2236 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*
2237

2239
2240 * Add a :namespace option to AR::Base#to_xml *Michael Koziarski*
2241
2242 * Deprecation tests. Remove warnings for dynamic finders and for the foo_count method if it's also an attribute. *Jeremy Kemper*
2243
2244 * Mock Time.now for more accurate Touch mixin tests. #6213 *Dan Peterson*
2245
2246 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
2247
2248 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
2249
2250 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
2251
2252 * 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*
2253
2254 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
2255
2256 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
2257
2258 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
2259
2260 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
2261
2262 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
2263
2264 * 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*
2265
2266 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
2267
2268 * 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*
2269
2270 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
2271
2272 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
2273
2274 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*
2275
2276 * MySQL: update test schema for MySQL 5 strict mode. #5861 *Tom Ward*
2277
2278 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2279
2280 * 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*
2281
2282 * 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*
2283
2284 # Create a tagging to associate the post and tag.
2285 post.tags << Tag.find_by_name('old')
2286 post.tags.create! :name => 'general'
2287
2288 # Would have been:
2289 post.taggings.create!(:tag => Tag.find_by_name('finally')
2290 transaction do
2291 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
2292 end
2293
2294 * Cache nil results for :included has_one associations also. #5787 *Michael Schoen*
2295
2296 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
2297
2298 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
2299 Example: Invoice::Lineitem is given table name invoice_lineitems
2300
2301 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2302 # people_active_last_name_index, people_active_deactivated_at_index
2303 add_index :people, [:active, :last_name]
2304 add_index :people, [:active, :deactivated_at]
2305 remove_index :people, [:active, :last_name]
2306 remove_index :people, [:active, :deactivated_at]
2307
2308 WARNING: backward-incompatibility. Multicolumn indexes created before this
2309 revision were named using the first column name only. Now they're uniquely
2310 named using all indexed columns.
2311
2312 To remove an old multicolumn index, remove_index :table_name, :first_column
2313
2314 * Fix for deep includes on the same association. *richcollins@gmail.com*
2315
2316 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
2317
2318 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
2319
2320 * 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*
2321
2322 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
2323
2324 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
2325
2326 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
2327
2328 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
2329
2330 * Formally deprecate the deprecated finders. *Michael Koziarski*
2331
2332 * Formally deprecate rich associations. *Michael Koziarski*
2333
2334 * Fixed that default timezones for new / initialize should uphold utc setting #5709 *daniluk@yahoo.com*
2335
2336 * Fix announcement of very long migration names. #5722 *blake@near-time.com*
2337
2338 * The exists? class method should treat a string argument as an id rather than as conditions. #5698 *jeremy@planetargon.com*
2339
2340 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
2341
2342 * Added support for conditions on Base.exists? #5689 [Josh Peek]. Examples:
2343
2344 assert (Topic.exists?(:author_name => "David"))
2345 assert (Topic.exists?(:author_name => "Mary", :approved => true))
2346 assert (Topic.exists?(["parent_id = ?", 1]))
2347

2349
2350 * Calculate sum with SQL, not Enumerable on HasManyThrough Associations. *Dan Peterson*
2351
2352 * Factor the attribute#{suffix} methods out of method_missing for easier extension. *Jeremy Kemper*
2353
2354 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
2355
2356 * Allow #count through a has_many association to accept :include. *Dan Peterson*
2357
2358 * create_table rdoc: suggest :id => false for habtm join tables. *Zed Shaw*
2359
2360 * PostgreSQL: return array fields as strings. #4664 *Robby Russell*
2361
2362 * 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*
2363
2364 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2365
2366 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2367
2368 * 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*
2369
2370 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*
2371
2372 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2373
2374 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2375
2376 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2377
2378 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2379
2380 * 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*
2381
2382 * 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*
2383
2384 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2385
2386 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2387
2388 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2389
2390 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2391
2392 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2393
2394 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2395
2396 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2397
2398 * 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*
2399 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2400 Person.transaction do
2401 # select * from people where id=1 for update
2402 person = Person.find(1, :lock => true)
2403 person.visits += 1
2404 person.save!
2405 end
2406
2407 * 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*
2408
2409 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2410
2411 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2412
2413 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2414
2415 * 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*
2416
2417 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2418
2419 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2420
2421 ...is the same as:
2422 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2423
2424 This makes it easier to pass in the options from a form or otherwise outside.
2425
2426
2427 * Fixed issues with BLOB limits, charsets, and booleans for Firebird #5194, #5191, #5189 *kennethkunz@gmail.com*

2434
2435 * Fixed that count distinct should use the selected column even when using :include #5251 *anna@wota.jp*
2436
2437 * 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*
2438
2439 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
2440
2441 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
2442
2443 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
2444 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
2445 Foo.find(:first, :conditions => ['bar_id = ?', bar])
2446
2447 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
2448
2449 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
2450
2451 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*
2452
2453 * Provide Association Extensions access to the instance that the association is being accessed from.
2454 Closes #4433 *Josh Susser*
2455
2456 * Update OpenBase adaterp's maintainer's email address. Closes #5176. *Derrick Spell*
2457
2458 * Add a quick note about :select and eagerly included associations. *Rick Olson*
2459
2460 * Add docs for the :as option in has_one associations. Closes #5144 *cdcarter@gmail.com*
2461
2462 * Fixed that has_many collections shouldn't load the entire association to do build or create *David Heinemeier Hansson*
2463
2464 * Added :allow_nil option for aggregations #5091 *Ian White*
2465
2466 * Fix Oracle boolean support and tests. Closes #5139. *Michael Schoen*
2467
2468 * 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*
2469
2470 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2471
2472 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2473
2474 * 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*
2475
2476 * Dates and times interpret empty strings as nil rather than 2000-01-01. #4830 *kajism@yahoo.com*

2483
2484 * Remove duplicate fixture entry in comments.yml. Closes #4923. *Blair Zajac <blair@orcaware.com>*
2485

2642 class Connection < ActiveRecord::Base
2643 belongs_to :user
2644 belongs_to :channel
2645 end
2646
2647 class Channel < ActiveRecord::Base
2648 has_many :connections
2649 has_many :contacts, :through => :connections, :class_name => 'User' # OLD
2650 has_many :contacts, :through => :connections, :source => :user # NEW

2656
2657 In this example, :include => false disables the default eager association from loading. :select changes the standard
2658 select clause. :joins specifies a join that is added to the end of the has_many :through query.
2659
2660 class Post < ActiveRecord::Base
2661 has_many :tags, :through => :taggings, :include => :tagging do
2662 def add_joins_and_select
2663 find :all, :select => 'tags.*, authors.id as author_id', :include => false,
2664 :joins => 'left outer join posts on taggings.taggable_id = posts.id left outer join authors on posts.author_id = authors.id'
2665 end
2666 end
2667 end

2671 * Don't classify the has_one class when eager loading, it is already singular. Add tests. (closes #4117) *Jonathan Viney*
2672
2673 * Quit ignoring default :include options in has_many :through calls *Mark James*
2674
2675 * Allow has_many :through associations to find the source association by setting a custom class (closes #4307) *Jonathan Viney*
2676
2677 * Eager Loading support added for has_many :through => :has_many associations (see below). *Rick Olson*
2678
2679 * Allow has_many :through to work on has_many associations (closes #3864) [sco@scottraymond.net] Example:
