76 ## Rails 3.1.1 (October 7, 2011) ##
77
78 * Raise an exception if the primary key of a model in an association is needed
79 but unknown. Fixes #3207.
80
81 *Jon Leighton*
82
83 * Add deprecation for the preload_associations method. Fixes #3022.
84
85 *Jon Leighton*
86
87 * Don't require a DB connection when loading a model that uses set_primary_key. GH #2807.
88
89 *Jon Leighton*
90
91 * Fix using select() with a habtm association, e.g. Person.friends.select(:name). GH #3030 and
92 \#2923.
93
94 *Hendy Tanata*
95
96 * Fix belongs_to polymorphic with custom primary key on target. GH #3104.
97
98 *Jon Leighton*
99
100 * CollectionProxy#replace should change the DB records rather than just mutating the array.
101 Fixes #3020.
102
103 *Jon Leighton*
104
105 * LRU cache in mysql and sqlite are now per-process caches.
106
107 * lib/active_record/connection_adapters/mysql_adapter.rb: LRU cache
108 keys are per process id.
109 * lib/active_record/connection_adapters/sqlite_adapter.rb: ditto
110
111 *Aaron Patterson*
112
113 * Database adapters use a statement pool for limiting the number of open
114 prepared statments on the database. The limit defaults to 1000, but can
115 be adjusted in your database config by changing 'statement_limit'.
116
117 * Fix clash between using 'preload', 'joins' or 'eager_load' in a default scope and including the
118 default scoped model in a nested through association. (GH #2834.) *Jon Leighton*
119
120 * Ensure we are not comparing a string with a symbol in HasManyAssociation#inverse_updates_counter_cache?.
121 Fixes GH #2755, where a counter cache could be decremented twice as far as it was supposed to be.
122
123 *Jon Leighton*
124
125 * Don't send any queries to the database when the foreign key of a belongs_to is nil. Fixes
126 GH #2828. *Georg Friedrich*
127
128 * Fixed find_in_batches method to not include order from default_scope. See GH #2832 *Arun Agrawal*
129
130 * Don't compute table name for abstract classes. Fixes problem with setting the primary key
131 in an abstract class. See GH #2791. *Akira Matsuda*
132
133 * Psych errors with poor yaml formatting are proxied. Fixes GH #2645 and
134 GH #2731
135
136 * Use the LIMIT word with the methods #last and #first. Fixes GH #2783 *Damien Mathieu*
137
138 ## Rails 3.1.0 (August 30, 2011) ##
139
140 * Add a proxy_association method to association proxies, which can be called by association
141 extensions to access information about the association. This replaces proxy_owner etc with
142 proxy_association.owner.
143
144 *Jon Leighton*
145
146 * Active Record's dynamic finder will now show a deprecation warning if you passing in less number of arguments than what you call in method signature. This behavior will raise ArgumentError in the next version of Rails *Prem Sichanugrist*
147
148 * Deprecated the AssociationCollection constant. CollectionProxy is now the appropriate constant
149 to use, though be warned that this is not really a public API.
150
151 This should solve upgrade problems with the will_paginate plugin (and perhaps others). Thanks
152 Paul Battley for reporting.
153
154 *Jon Leighton*
155
156 * ActiveRecord::MacroReflection::AssociationReflection#build_record has a new method signature.
157
158 Before: def build_association(*options)
159 After: def build_association(*options, &block)
160
161 Users who are redefining this method to extend functionality should ensure that the block is
162 passed through to ActiveRecord::Base#new.
163
164 This change is necessary to fix https://github.com/rails/rails/issues/1842.
165
166 A deprecation warning and workaround has been added to 3.1, but authors will need to update
167 their code for it to work correctly in 3.2.
168
169 *Jon Leighton*
170
171 * AR#pluralize_table_names can be used to singularize/pluralize table name of an individual model:
172
173 class User < ActiveRecord::Base
174 self.pluralize_table_names = false
175 end
176
177 Previously this could only be set globally for all models through ActiveRecord::Base.pluralize_table_names. *Guillermo Iguaran*
178
179 * Add block setting of attributes to singular associations:
180
181 class User < ActiveRecord::Base
182 has_one :account
183 end
184
185 user.build_account{ |a| a.credit_limit => 100.0 }
186
187 The block is called after the instance has been initialized. *Andrew White*
188
189 * 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*
190
191 * CSV Fixtures are deprecated and support will be removed in Rails 3.2.0
192
193 * AR#new, AR#create, AR#create!, AR#update_attributes and AR#update_attributes! all accept a second hash as option that allows you
194 to specify which role to consider when assigning attributes. This is built on top of ActiveModel's
195 new mass assignment capabilities:
196
197 class Post < ActiveRecord::Base
198 attr_accessible :title
199 attr_accessible :title, :published_at, :as => :admin
200 end
201
202 Post.new(params[:post], :as => :admin)
203
204 assign_attributes() with similar API was also added and attributes=(params, guard) was deprecated.
205
206 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.
207
208 *Josh Kalderimis*
209
210 * default_scope can take a block, lambda, or any other object which responds to `call` for lazy
211 evaluation:
212
213 default_scope { ... }
214 default_scope lambda { ... }
215 default_scope method(:foo)
216
217 This feature was originally implemented by Tim Morgan, but was then removed in favour of
218 defining a 'default_scope' class method, but has now been added back in by Jon Leighton.
219 The relevant lighthouse ticket is #1812.
220
221 * Default scopes are now evaluated at the latest possible moment, to avoid problems where
222 scopes would be created which would implicitly contain the default scope, which would then
223 be impossible to get rid of via Model.unscoped.
224
225 Note that this means that if you are inspecting the internal structure of an
226 ActiveRecord::Relation, it will *not* contain the default scope, though the resulting
227 query will do. You can get a relation containing the default scope by calling
228 ActiveRecord#with_default_scope, though this is not part of the public API.
229
230 *Jon Leighton*
231
232 * If you wish to merge default scopes in special ways, it is recommended to define your default
233 scope as a class method and use the standard techniques for sharing code (inheritance, mixins,
234 etc.):
235
236 class Post < ActiveRecord::Base
237 def self.default_scope
238 where(:published => true).where(:hidden => false)
239 end
240 end
241
242 *Jon Leighton*
243
244 * PostgreSQL adapter only supports PostgreSQL version 8.2 and higher.
245
246 * ConnectionManagement middleware is changed to clean up the connection pool
247 after the rack body has been flushed.
248
249 * Added an update_column method on ActiveRecord. This new method updates a given attribute on an object, skipping validations and callbacks.
250 It is recommended to use #update_attribute unless you are sure you do not want to execute any callback, including the modification of
251 the updated_at column. It should not be called on new records.
252 Example:
253
254 User.first.update_column(:name, "sebastian") # => true
255
256 *Sebastian Martinez*
257
258 * Associations with a :through option can now use *any* association as the
259 through or source association, including other associations which have a
260 :through option and has_and_belongs_to_many associations
261
262 *Jon Leighton*
263
264 * The configuration for the current database connection is now accessible via
265 ActiveRecord::Base.connection_config. *fxn*
266
267 * limits and offsets are removed from COUNT queries unless both are supplied.
268 For example:
269
270 People.limit(1).count # => 'SELECT COUNT(*) FROM people'
271 People.offset(1).count # => 'SELECT COUNT(*) FROM people'
272 People.limit(1).offset(1).count # => 'SELECT COUNT(*) FROM people LIMIT 1 OFFSET 1'
273
274 *lighthouse #6262*
275
276 * ActiveRecord::Associations::AssociationProxy has been split. There is now an Association class
277 (and subclasses) which are responsible for operating on associations, and then a separate,
278 thin wrapper called CollectionProxy, which proxies collection associations.
279
280 This prevents namespace pollution, separates concerns, and will allow further refactorings.
281
282 Singular associations (has_one, belongs_to) no longer have a proxy at all. They simply return
283 the associated record or nil. This means that you should not use undocumented methods such
284 as bob.mother.create - use bob.create_mother instead.
285
286 *Jon Leighton*
287
288 * Make has_many :through associations work correctly when you build a record and then save it. This
289 requires you to set the :inverse_of option on the source reflection on the join model, like so:
290
291 class Post < ActiveRecord::Base
292 has_many :taggings
293 has_many :tags, :through => :taggings
294 end
295
296 class Tagging < ActiveRecord::Base
297 belongs_to :post
298 belongs_to :tag, :inverse_of => :tagging # :inverse_of must be set!
299 end
300
301 class Tag < ActiveRecord::Base
302 has_many :taggings
303 has_many :posts, :through => :taggings
304 end
305
306 post = Post.first
307 tag = post.tags.build :name => "ruby"
308 tag.save # will save a Taggable linking to the post
309
310 *Jon Leighton*
311
312 * Support the :dependent option on has_many :through associations. For historical and practical
313 reasons, :delete_all is the default deletion strategy employed by association.delete(*records),
314 despite the fact that the default strategy is :nullify for regular has_many. Also, this only
315 works at all if the source reflection is a belongs_to. For other situations, you should directly
316 modify the through association.
317
318 *Jon Leighton*
319
320 * Changed the behaviour of association.destroy for has_and_belongs_to_many and has_many :through.
321 From now on, 'destroy' or 'delete' on an association will be taken to mean 'get rid of the link',
322 not (necessarily) 'get rid of the associated records'.
323
324 Previously, has_and_belongs_to_many.destroy(*records) would destroy the records themselves. It
325 would not delete any records in the join table. Now, it deletes the records in the join table.
326
327 Previously, has_many_through.destroy(*records) would destroy the records themselves, and the
328 records in the join table. [Note: This has not always been the case; previous version of Rails
329 only deleted the records themselves.] Now, it destroys only the records in the join table.
330
331 Note that this change is backwards-incompatible to an extent, but there is unfortunately no
332 way to 'deprecate' it before changing it. The change is being made in order to have
333 consistency as to the meaning of 'destroy' or 'delete' across the different types of associations.
334
335 If you wish to destroy the records themselves, you can do records.association.each(&:destroy)
336
337 *Jon Leighton*
338
339 * 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*
340
341 Example:
342
343 change_table(:users, :bulk => true) do |t|
344 t.string :company_name
345 t.change :birthdate, :datetime
346 end
347
348 This will now result in:
349
350 ALTER TABLE `users` ADD COLUMN `company_name` varchar(255), CHANGE `updated_at` `updated_at` datetime DEFAULT NULL
351
352 * Removed support for accessing attributes on a has_and_belongs_to_many join table. This has been
353 documented as deprecated behaviour since April 2006. Please use has_many :through instead.
354 *Jon Leighton*
355
356 * Added a create_association! method for has_one and belongs_to associations. *Jon Leighton*
357
358 * Migration files generated from model and constructive migration generators
359 (for example, add_name_to_users) use the reversible migration's `change`
360 method instead of the ordinary `up` and `down` methods. *Prem Sichanugrist*
361
362 * Removed support for interpolating string SQL conditions on associations. Instead, you should
363 use a proc, like so:
364
365 Before:
366
367 has_many :things, :conditions => 'foo = #{bar}'
368
369 After:
370
371 has_many :things, :conditions => proc { "foo = #{bar}" }
372
373 Inside the proc, 'self' is the object which is the owner of the association, unless you are
374 eager loading the association, in which case 'self' is the class which the association is within.
375
376 You can have any "normal" conditions inside the proc, so the following will work too:
377
378 has_many :things, :conditions => proc { ["foo = ?", bar] }
379
380 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
381 'record' to get the record being inserted or deleted. This is now passed as an argument to
382 the proc.
383
384 * Added ActiveRecord::Base#has_secure_password (via ActiveModel::SecurePassword) to encapsulate dead-simple password usage with BCrypt encryption and salting [DHH]. Example:
385
386 # Schema: User(name:string, password_digest:string, password_salt:string)
387 class User < ActiveRecord::Base
388 has_secure_password
389 end
390
391 user = User.new(:name => "david", :password => "", :password_confirmation => "nomatch")
392 user.save # => false, password required
393 user.password = "mUc3m00RsqyRe"
394 user.save # => false, confirmation doesn't match
395 user.password_confirmation = "mUc3m00RsqyRe"
396 user.save # => true
397 user.authenticate("notright") # => false
398 user.authenticate("mUc3m00RsqyRe") # => user
399 User.find_by_name("david").try(:authenticate, "notright") # => nil
400 User.find_by_name("david").try(:authenticate, "mUc3m00RsqyRe") # => user
401
402
403 * When a model is generated add_index is added by default for belongs_to or references columns
404
405 rails g model post user:belongs_to will generate the following:
406
407 class CreatePosts < ActiveRecord::Migration
408 def change
409 create_table :posts do |t|
410 t.belongs_to :user
411 t.timestamps
412 end
413 add_index :posts, :user_id
414 end
415 end
416
417 *Santiago Pastorino*
418
419 * Setting the id of a belongs_to object will update the reference to the
420 object. *#2989 state:resolved*
421
422 * ActiveRecord::Base#dup and ActiveRecord::Base#clone semantics have changed
423 to closer match normal Ruby dup and clone semantics.
424
425 * Calling ActiveRecord::Base#clone will result in a shallow copy of the record,
426 including copying the frozen state. No callbacks will be called.
427
428 * Calling ActiveRecord::Base#dup will duplicate the record, including calling
429 after initialize hooks. Frozen state will not be copied, and all associations
430 will be cleared. A duped record will return true for new_record?, have a nil
431 id field, and is saveable.
432
433 * Migrations can be defined as reversible, meaning that the migration system
434 will figure out how to reverse your migration. To use reversible migrations,
435 just define the "change" method. For example:
436
437 class MyMigration < ActiveRecord::Migration
438 def change
439 create_table(:horses) do
440 t.column :content, :text
441 t.column :remind_at, :datetime
442 end
443 end
444 end
445
446 Some things cannot be automatically reversed for you. If you know how to
447 reverse those things, you should define 'up' and 'down' in your migration. If
448 you define something in `change` that cannot be reversed, an
449 IrreversibleMigration exception will be raised when going down.
450
451 * Migrations should use instance methods rather than class methods:
452 class FooMigration < ActiveRecord::Migration
453 def up
454 ...
455 end
456 end
457
458 *Aaron Patterson*
459
460 * has_one maintains the association with separate after_create/after_update instead
461 of a single after_save. *fxn*
462
463 * The following code:
464
465 Model.limit(10).scoping { Model.count }
466
467 now generates the following SQL:
468
469 SELECT COUNT(*) FROM models LIMIT 10
470
471 This may not return what you want. Instead, you may with to do something
472 like this:
473
474 Model.limit(10).scoping { Model.all.size }
475

484
485 * Quote the ORDER BY clause in batched finds - fixes #6620 *Andrew White*
486

517 ## Rails 3.0.5 (February 26, 2011) ##
518
519 * Model.where(:column => 1).where(:column => 2) will always produce an AND
520 query.
521
522 *Aaron Patterson*
523
524 * Deprecated support for interpolated association conditions in the form of :conditions => 'foo = #{bar}'.
525
526 Instead, you should use a proc, like so:
527
528 Before:
529
530 has_many :things, :conditions => 'foo = #{bar}'
531
532 After:
533
534 has_many :things, :conditions => proc { "foo = #{bar}" }
535
536 Inside the proc, 'self' is the object which is the owner of the association, unless you are
537 eager loading the association, in which case 'self' is the class which the association is within.
538
539 You can have any "normal" conditions inside the proc, so the following will work too:
540
541 has_many :things, :conditions => proc { ["foo = ?", bar] }
542
543 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
544 'record' to get the record being inserted or deleted. This is now passed as an argument to
545 the proc.

550 ## Rails 3.0.4 (February 8, 2011) ##
551
552 * Added deprecation warning for has_and_belongs_to_many associations where the join table has
553 additional attributes other than the keys. Access to these attributes is removed in 3.1.
554 Please use has_many :through instead. *Jon Leighton*
555
556
557 ## Rails 3.0.3 (November 16, 2010) ##
558
559 * Support find by class like this: Post.where(:name => Post)
560
561
562 ## Rails 3.0.2 (November 15, 2010) ##
563
564 * Dramatic speed increase (see: http://engineering.attinteractive.com/2010/10/arel-two-point-ohhhhh-yaaaaaa/) *Aaron Patterson*
565
566 * reorder is deprecated in favor of except(:order).order(...) *Santiago Pastorino*
567
568 * except is now AR public API
569
570 Model.order('name').except(:order).order('salary')
571
572 generates:
573
574 SELECT * FROM models ORDER BY salary
575
576 *Santiago Pastorino*
577
578 * The following code:
579
580 Model.limit(10).scoping { Model.count }
581
582 now generates the following SQL:
583
584 SELECT COUNT(*) FROM models LIMIT 10
585
586 This may not return what you want. Instead, you may with to do something
587 like this:
588
589 Model.limit(10).scoping { Model.all.size }
590
591 *Aaron Patterson*
592
593
594 ## Rails 3.0.1 (October 15, 2010) ##
595
596 * Introduce a fix for CVE-2010-3993
597
598
599 ## Rails 3.0.0 (August 29, 2010) ##
600
601 * Changed update_attribute to not run callbacks and update the record directly in the database *Neeraj Singh*
602
603 * Add scoping and unscoped as the syntax to replace the old with_scope and with_exclusive_scope *José Valim*
604
605 * New rake task, db:migrate:status, displays status of migrations #4947 *Kevin Skoglund*
606
607 * select and order for ActiveRecord now always concatenate nested calls. Use reorder if you want the original order to be overwritten *Santiago Pastorino*
608
609 * PostgreSQL: ensure the database time zone matches Ruby's time zone #4895 *Aaron Patterson*
610
611 * Fixed that ActiveRecord::Base.compute_type would swallow NoMethodError #4751 *Andrew Bloomgarden, Andrew White*
612
613 * Add index length support for MySQL. #1852 *Emili Parreno, Pratik Naik*
614
615 Example:
616
617 add_index(:accounts, :name, :name => 'by_name', :length => 10)
618 => CREATE INDEX by_name ON accounts(name(10))
619
620 add_index(:accounts, [:name, :surname], :name => 'by_name_surname', :length => {:name => 10, :surname => 15})
621 => CREATE INDEX by_name_surname ON accounts(name(10), surname(15))
622
623 * find_or_create_by_attr(value, ...) works when attr is protected. #4457 *Santiago Pastorino, Marc-André Lafortune*
624
625 * New callbacks: after_commit and after_rollback. Do expensive operations like image thumbnailing after_commit instead of after_save. #2991 *Brian Durand*
626
627 * 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*
628
629 * 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*
630
631 * PostgreSQL: drop support for old postgres driver. Use pg 0.9.0 or later. *Jeremy Kemper*
632
633 * Observers can prevent records from saving by returning false, just like before_save and friends. #4087 *Mislav Marohnić*
634
635 * Add Relation extensions. *Pratik Naik*
636
637 users = User.where(:admin => true).extending(User::AdminPowers)
638
639 latest_users = User.order('created_at DESC') do
640 def posts_count
641 Post.count(:user_id => to_a.map(&:id))
642 end
643 end
644
645 * To prefix the table names of all models in a module, define self.table_name_prefix on the module. #4032 *Andrew White*
646
647 * 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*
648
649 * 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*
650
651 * Allow relations to be used as scope.
652
653 class Item
654 scope :red, where(:colour => 'red')
655 end
656
657 Item.red.limit(10) # Ten red items
658
659 * Rename named_scope to scope. *Pratik Naik*
660
661 * Changed ActiveRecord::Base.store_full_sti_class to be true by default reflecting the previously announced Rails 3 default *DHH*
662
663 * Add Relation#except. *Pratik Naik*
664
665 one_red_item = Item.where(:colour => 'red').limit(1)
666 all_items = one_red_item.except(:where, :limit)
667
668 * Add Relation#delete_all. *Pratik Naik*
669
670 Item.where(:colour => 'red').delete_all
671
672 * Add Model.having and Relation#having. *Pratik Naik*
673
674 Developer.group("salary").having("sum(salary) > 10000").select("salary")
675
676 * Add Relation#count. *Pratik Naik*
677
678 legends = People.where("age > 100")
679 legends.count
680 legends.count(:age, :distinct => true)
681 legends.select('id').count
682
683 * Add Model.readonly and association_collection#readonly finder method. *Pratik Naik*
684
685 Post.readonly.to_a # Load all posts in readonly mode
686 @user.items.readonly(false).to_a # Load all the user items in writable mode
687
688 * Add .lock finder method *Pratik Naik*
689
690 User.lock.where(:name => 'lifo').to_a
691
692 old_items = Item.where("age > 100")
693 old_items.lock.each {|i| .. }
694
695 * Add Model.from and association_collection#from finder methods *Pratik Naik*
696
697 user = User.scoped
698 user.select('*').from('users, items')
699
700 * Add relation.destroy_all *Pratik Naik*
701
702 old_items = Item.where("age > 100")
703 old_items.destroy_all
704
705 * Add relation.exists? *Pratik Naik*
706
707 red_items = Item.where(:colours => 'red')
708 red_items.exists?
709 red_items.exists?(1)
710
711 * Add find(ids) to relations. *Pratik Naik*
712
713 old_users = User.order("age DESC")
714 old_users.find(1)
715 old_users.find(1, 2, 3)
716
717 * Add new finder methods to association collection. *Pratik Naik*
718
719 class User < ActiveRecord::Base
720 has_many :items
721 end
722
723 user = User.first
724 user.items.where(:items => {:colour => 'red'})
725 user.items.select('items.id')
726
727 * Add relation.reload to force reloading the records. *Pratik Naik*
728
729 topics = Topic.scoped
730 topics.to_a # force load
731 topics.first # returns a cached record
732 topics.reload
733 topics.first # Fetches a new record from the database
734
735 * Rename Model.conditions and relation.conditions to .where. *Pratik Naik*
736
737 Before :
738 User.conditions(:name => 'lifo')
739 User.select('id').conditions(["age > ?", 21])
740
741 Now :
742 User.where(:name => 'lifo')
743 User.select('id').where(["age > ?", 21])
744
745 * Add Model.select/group/order/limit/joins/conditions/preload/eager_load class methods returning a lazy relation. *Pratik Naik*
746
747 Examples :
748
749 posts = Post.select('id).order('name') # Returns a lazy relation
750 posts.each {|p| puts p.id } # Fires "select id from posts order by name"
751
752 * Model.scoped now returns a relation if invoked without any arguments. *Pratik Naik*
753
754 Example :
755
756 posts = Post.scoped
757 posts.size # Fires "select count(*) from posts" and returns the count
758 posts.each {|p| puts p.name } # Fires "select * from posts" and loads post objects
759
760 * Association inverses for belongs_to, has_one, and has_many. Optimization to reduce database queries. #3533 *Murray Steele*
761
762 # post.comments sets each comment's post without needing to :include
763 class Post < ActiveRecord::Base
764 has_many :comments, :inverse_of => :post
765 end
766
767 * MySQL: add_ and change_column support positioning. #3286 *Ben Marini*
768
769 * Reset your Active Record counter caches with the reset_counter_cache class method. #1211 *Mike Breen, Gabe da Silveira*
770
771 * Remove support for SQLite 2. Please upgrade to SQLite 3+ or install the plugin from git://github.com/rails/sqlite2_adapter.git *Pratik Naik*
772
773 * PostgreSQL: XML datatype support. #1874 *Leonardo Borges*
774
775 * 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*
776
777 * SQLite: drop support for 'dbfile' option in favor of 'database.' #2363 *Paul Hinze, Jeremy Kemper*
778
779 * Added :primary_key option to belongs_to associations. #765 *Szymon Nowak, Philip Hallstrom, Noel Rocha*
780 # employees.company_name references companies.name
781 Employee.belongs_to :company, :primary_key => 'name', :foreign_key => 'company_name'
782
783 * Implement #many? for NamedScope and AssociationCollection using #size. #1500 *Chris Kampmeier*
784
785 * Added :touch option to belongs_to associations that will touch the parent record when the current record is saved or destroyed *DHH*
786
787 * Added ActiveRecord::Base#touch to update the updated_at/on attributes (or another specified timestamp) with the current time *DHH*
788
789
790 ## 2.3.2 Final (March 15, 2009) ##

793
794 * Added that ActiveRecord::Base.exists? can be called with no arguments #1817 *Scott Taylor*
795
796 * Add Support for updating deeply nested models from a single form. #1202 *Eloy Duran*

799 has_one :author
800 has_many :pages
801
802 accepts_nested_attributes_for :author, :pages
803 end
804
805 * Make after_save callbacks fire only if the record was successfully saved. #1735 *Michael Lovitt*
806
807 Previously the callbacks would fire if a before_save cancelled saving.
808
809 * Support nested transactions using database savepoints. #383 *Jonathan Viney, Hongli Lai*
810
811 * Added dynamic scopes ala dynamic finders #1648 *Yaroslav Markin*
812
813 * Fixed that ActiveRecord::Base#new_record? should return false (not nil) for existing records #1219 *Yaroslav Markin*
814
815 * I18n the word separator for error messages. Introduces the activerecord.errors.format.separator translation key. #1294 *Akira Matsuda*
816
817 * Add :having as a key to find and the relevant associations. *Emilio Tagua*
818
819 * Added default_scope to Base #1381 [Paweł Kondzior]. Example:
820
821 class Person < ActiveRecord::Base
822 default_scope :order => 'last_name, first_name'
823 end
824
825 class Company < ActiveRecord::Base
826 has_many :people
827 end
828
829 Person.all # => Person.find(:all, :order => 'last_name, first_name')
830 Company.find(1).people # => Person.find(:all, :order => 'last_name, first_name', :conditions => { :company_id => 1 })
831
832
833 ## 2.2.1 RC2 (November 14th, 2008) ##
834
835 * Ensure indices don't flip order in schema.rb #1266 *Jordi Bunster*
836
837 * Fixed that serialized strings should never be type-casted (i.e. turning "Yes" to a boolean) #857 *Andreas Korth*
838
839
840 ## 2.2.0 RC1 (October 24th, 2008) ##
841
842 * Skip collection ids reader optimization if using :finder_sql *Jeremy Kemper*
843
844 * Add Model#delete instance method, similar to Model.delete class method. #1086 *Hongli Lai (Phusion)*
845
846 * MySQL: cope with quirky default values for not-null text columns. #1043 *Frederick Cheung*
847
848 * Multiparameter attributes skip time zone conversion for time-only columns [#1030 state:resolved] *Geoff Buesing*
849
850 * Base.skip_time_zone_conversion_for_attributes uses class_inheritable_accessor, so that subclasses don't overwrite Base [#346 state:resolved] *Emilio Tagua*
851
852 * Added find_last_by dynamic finder #762 *Emilio Tagua*
853
854 * Internal API: configurable association options and build_association method for reflections so plugins may extend and override. #985 *Hongli Lai (Phusion)*
855
856 * Changed benchmarks to be reported in milliseconds *David Heinemeier Hansson*
857
858 * Connection pooling. #936 *Nick Sieger*
859
860 * Merge scoped :joins together instead of overwriting them. May expose scoping bugs in your code! #501 *Andrew White*
861
862 * 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*
863
864 * Transactional migrations for databases which support them. #834 *divoxx, Adam Wiggins, Tarmo Tänav*
865
866 * Set config.active_record.timestamped_migrations = false to have migrations with numeric prefix instead of UTC timestamp. #446. *Andrew Stone, Nik Wakelin*
867
868 * change_column_default preserves the not-null constraint. #617 *Tarmo Tänav*
869
870 * Fixed that create database statements would always include "DEFAULT NULL" (Nick Sieger) *#334*
871
872 * Add :tokenizer option to validates_length_of to specify how to split up the attribute string. #507. [David Lowenfels] Example :
873
874 \# Ensure essay contains at least 100 words.
875 validates_length_of :essay, :minimum => 100, :too_short => "Your essay must be at least %d words."), :tokenizer => lambda {|str| str.scan(/\w+/) }
876
877 * Allow conditions on multiple tables to be specified using hash. [Pratik Naik]. Example:
878
879 User.all :joins => :items, :conditions => { :age => 10, :items => { :color => 'black' } }
880 Item.first :conditions => { :items => { :color => 'red' } }
881
882 * Always treat integer :limit as byte length. #420 *Tarmo Tänav*
883
884 * Partial updates don't update lock_version if nothing changed. #426 *Daniel Morrison*
885
886 * Fix column collision with named_scope and :joins. #46 *Duncan Beevers, Mark Catley*
887
888 * db:migrate:down and :up update schema_migrations. #369 *Michael Raidel, RaceCondition*
889
890 * PostgreSQL: support :conditions => [':foo::integer', { :foo => 1 }] without treating the ::integer typecast as a bind variable. *Tarmo Tänav*
891
892 * MySQL: rename_column preserves column defaults. #466 *Diego Algorta*
893
894 * Add :from option to calculations. #397 *Ben Munat*
895
896 * Add :validate option to associations to enable/disable the automatic validation of associated models. Resolves #301. *Jan De Poorter*
897
898 * PostgreSQL: use 'INSERT ... RETURNING id' for 8.2 and later. *Jeremy Kemper*
899
900 * Added SQL escaping for :limit and :offset in MySQL *Jonathan Wiess*
901
902
903 ## 2.1.0 (May 31st, 2008) ##
904
905 * Add ActiveRecord::Base.sti_name that checks ActiveRecord::Base#store_full_sti_class? and returns either the full or demodulized name. *Rick Olson*
906
907 * Add first/last methods to associations/named_scope. Resolved #226. *Ryan Bates*
908
909 * Added SQL escaping for :limit and :offset #288 *Aaron Bedra, Steven Bristol, Jonathan Wiess*
910
911 * Added first/last methods to associations/named_scope. Resolved #226. *Ryan Bates*

914
915 * Added protection against duplicate migration names (Aslak Hellesøy) *#112*
916
917 * 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*
918
919 * 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*
920
921 * Added change_table for migrations (Jeff Dean) [#71]. Example:
922
923 change_table :videos do |t|
924 t.timestamps # adds created_at, updated_at
925 t.belongs_to :goat # adds goat_id integer
926 t.string :name, :email, :limit => 20 # adds name and email both with a 20 char limit
927 t.remove :name, :email # removes the name and email columns
928 end
929
930 * Fixed has_many :through .create with no parameters caused a "can't dup NilClass" error (Steven Soroka) *#85*
931
932 * Added block-setting of attributes for Base.create like Base.new already has (Adam Meehan) *#39*
933
934 * Fixed that pessimistic locking you reference the quoted table name (Josh Susser) *#67*
935
936 * Fixed that change_column should be able to use :null => true on a field that formerly had false [Nate Wiger] *#26*
937
938 * Added that the MySQL adapter should map integer to either smallint, int, or bigint depending on the :limit just like PostgreSQL *David Heinemeier Hansson*
939
940 * Change validates_uniqueness_of :case_sensitive option default back to true (from [9160]). Love your database columns, don't LOWER them. *Rick Olson*
941
942 * Add support for interleaving migrations by storing which migrations have run in the new schema_migrations table. Closes #11493 *Jordi Bunster*
943
944 * ActiveRecord::Base#sum defaults to 0 if no rows are returned. Closes #11550 *Kamal Fariz Mahyuddin*
945
946 * Ensure that respond_to? considers dynamic finder methods. Closes #11538. *James Mead*
947
948 * Ensure that save on parent object fails for invalid has_one association. Closes #10518. *Pratik Naik*
949
950 * Remove duplicate code from associations. *Pratik Naik*
951
952 * Refactor HasManyThroughAssociation to inherit from HasManyAssociation. Association callbacks and <association>_ids= now work with hm:t. #11516 *Ruy Asan*
953
954 * Ensure HABTM#create and HABTM#build do not load entire association. *Pratik Naik*
955
956 * Improve documentation. *Xavier Noria, Jack Danger Canty, leethal*
957
958 * Tweak ActiveRecord::Base#to_json to include a root value in the returned hash: {"post": {"title": ...}} *Rick Olson*
959
960 Post.find(1).to_json # => {"title": ...}
961 config.active_record.include_root_in_json = true
962 Post.find(1).to_json # => {"post": {"title": ...}}
963
964 * Add efficient #include? to AssociationCollection (for has_many/has_many :through/habtm). *stopdropandrew*
965
966 * PostgreSQL: create_ and drop_database support. #9042 *ez, pedz, Nick Sieger*
967
968 * Ensure that validates_uniqueness_of works with with_scope. Closes #9235. *Nik Wakelin, cavalle*
969
970 * Partial updates include only unsaved attributes. Off by default; set YourClass.partial_updates = true to enable. *Jeremy Kemper*
971
972 * Removing unnecessary uses_tzinfo helper from tests, given that TZInfo is now bundled *Geoff Buesing*
973
974 * Fixed that validates_size_of :within works in associations #11295, #10019 *cavalle*
975
976 * Track changes to unsaved attributes. *Jeremy Kemper*
977
978 * 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*
979
980 * Fixed that has_many :through would ignore the hash conditions #11447 *Emilio Tagua*
981
982 * Fix issue where the :uniq option of a has_many :through association is ignored when find(:all) is called. Closes #9407 *cavalle*
983
984 * Fix duplicate table alias error when including an association with a has_many :through association on the same join table. Closes #7310 *cavalle*
985
986 * More efficient association preloading code that compacts a through_records array in a central location. Closes #11427 *Jack Danger Canty*
987
988 * Improve documentation. *Ryan Bigg, Jan De Poorter, Cheah Chu Yeow, Xavier Shay, Jack Danger Canty, Emilio Tagua, Xavier Noria, Sunny Ripert*
989
990 * Fixed that ActiveRecord#Base.find_or_create/initialize would not honor attr_protected/accessible when used with a hash #11422 *Emilio Tagua*
991
992 * Added ActiveRecord#Base.all/first/last as aliases for find(:all/:first/:last) #11413 *nkallen, Chris O'Sullivan*
993
994 * Merge the has_finder gem, renamed as 'named_scope'. #11404 *nkallen*

1340
1341 * Don't clobber includes passed to has_many.count *Jack Danger Canty*
1342
1343 * Make sure has_many uses :include when counting *Jack Danger Canty*
1344

1348 - Move method definition to the class, instead of the instance
1349 - Always generate the readers, writers and predicate methods.

1375
1376 NEW
1377 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is visitor_id
1378
1379 * Remove spurious tests from deprecated_associations_test, most of these aren't deprecated, and are duplicated in associations_test. Closes #8987 *Pratik Naik*

1428
1429 * find gracefully copes with blank :conditions. #7599 *Dan Manges, johnnyb*
1430
1431 * validates_numericality_of takes :greater_than, :greater_than_or_equal_to, :equal_to, :less_than, :less_than_or_equal_to, :odd, and :even options. #3952 *Bob Silva, Dan Kubb, Josh Peek*
1432
1433 * MySQL: create_database takes :charset and :collation options. Charset defaults to utf8. #8448 *matt*
1434
1435 * Find with a list of ids supports limit/offset. #8437 *hrudududu*
1436
1437 * Optimistic locking: revert the lock version when an update fails. #7840 *plang*
1438
1439 * Migrations: add_column supports custom column types. #7742 *jsgarvin, Theory*
1440
1441 * 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*
1442
1443 * Ensure that associations with :dependent => :delete_all respect :conditions option. Closes #8034 *Jack Danger Canty, Josh Peek, Rick Olson*
1444
1445 * belongs_to assignment creates a new proxy rather than modifying its target in-place. #8412 *mmangino@elevatedrails.com*
1446

1458
1459 * Document :allow_nil option for validates_acceptance_of since it defaults to true. *tzaharia*
1460
1461 * Update documentation for :dependent declaration so that it explicitly uses the non-deprecated API. *Jack Danger Canty*
1462
1463 * Add documentation caveat about when to use count_by_sql. *fearoffish*
1464
1465 * Enhance documentation for increment_counter and decrement_counter. *fearoffish*
1466
1467 * Provide brief introduction to what optimistic locking is. *fearoffish*
1468
1469 * Add documentation for :encoding option to mysql adapter. *marclove*
1470
1471 * Added short-hand declaration style to migrations (inspiration from Sexy Migrations, http://errtheblog.com/post/2381) [David Heinemeier Hansson]. Example:
1472
1473 create_table "products" do |t|
1474 t.column "shop_id", :integer
1475 t.column "creator_id", :integer
1476 t.column "name", :string, :default => "Untitled"
1477 t.column "value", :string, :default => "Untitled"
1478 t.column "created_at", :datetime
1479 t.column "updated_at", :datetime
1480 end
1481
1482 ...can now be written as:
1483
1484 create_table :products do |t|
1485 t.integer :shop_id, :creator_id
1486 t.string :name, :value, :default => "Untitled"
1487 t.timestamps
1488 end
1489
1490 * 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*
1491
1492 * Improve performance of calling .create on has_many :through associations. *evan*
1493
1494 * Improved cloning performance by relying less on exception raising #8159 *Blaine*
1495

1497
1498 * Added yielding of Builder instance for ActiveRecord::Base#to_xml calls *David Heinemeier Hansson*
1499

1502 * Add helpful debugging info to the ActiveRecord::StatementInvalid exception in ActiveRecord::ConnectionAdapters::SqliteAdapter#table_structure. Closes #7925. *court3nay*
1503
1504 * SQLite: binary escaping works with $KCODE='u'. #7862 *tsuka*
1505
1506 * Base#to_xml supports serialized attributes. #7502 *jonathan*
1507
1508 * Base.update_all :order and :limit options. Useful for MySQL updates that must be ordered to avoid violating unique constraints. *Jeremy Kemper*
1509
1510 * 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*
1511
1512 * 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*
1513
1514 * 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*
1515
1516 * 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*
1517
1518 * Allow a polymorphic :source for has_many :through associations. Closes #7143 *protocool*
1519
1520 * Consistent public/protected/private visibility for chained methods. #7813 *Dan Manges*
1521
1522 * Oracle: fix quoted primary keys and datetime overflow. #7798 *Michael Schoen*
1523
1524 * Consistently quote primary key column names. #7763 *toolmantim*
1525
1526 * Fixtures: fix YAML ordered map support. #2665 *Manuel Holtgrewe, nfbuckley*
1527
1528 * DateTimes assume the default timezone. #7764 *Geoff Buesing*
1529
1530 * Sybase: hide timestamp columns since they're inherently read-only. #7716 *Mike Joyce*
1531
1532 * Oracle: overflow Time to DateTime. #7718 *Michael Schoen*
1533
1534 * PostgreSQL: don't use async_exec and async_query with postgres-pr. #7727, #7762 *flowdelic, toolmantim*
1535
1536 * Fix has_many :through << with custom foreign keys. #6466, #7153 *naffis, Rich Collins*
1537
1538 * Test DateTime native type in migrations, including an edge case with dates
1539 during calendar reform. #7649, #7724 *fedot, Geoff Buesing*
1540
1541 * SQLServer: correctly schema-dump tables with no indexes or descending indexes. #7333, #7703 *Jakob Skjerning, Tom Ward*
1542
1543 * SQLServer: recognize real column type as Ruby float. #7057 *sethladd, Tom Ward*
1544
1545 * Added fixtures :all as a way of loading all fixtures in the fixture directory at once #7214 *Manfred Stienstra*
1546
1547 * Added database connection as a yield parameter to ActiveRecord::Base.transaction so you can manually rollback [David Heinemeier Hansson]. Example:
1548
1549 transaction do |transaction|
1550 david.withdrawal(100)
1551 mary.deposit(100)
1552 transaction.rollback! # rolls back the transaction that was otherwise going to be successful
1553 end
1554
1555 * Made increment_counter/decrement_counter play nicely with optimistic locking, and added a more general update_counters method *Jamis Buck*
1556
1557 * 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*
1558 Task.cache { Task.find(1); Task.find(1) } # => 1 query
1559
1560 * 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*
1561
1562 * Oracle: fix lob and text default handling. #7344 *gfriedrich, Michael Schoen*
1563
1564 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
1565
1566 * MySQL: blob and text columns may not have defaults in 5.x. Update fixtures schema for strict mode. #6695 *Dan Kubb*
1567
1568 * 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*
1569
1570 * MySQL: SET SQL_AUTO_IS_NULL=0 so 'where id is null' doesn't select the last inserted id. #6778 *Jonathan Viney, timc*
1571
1572 * Use Date#to_s(:db) for quoted dates. #7411 *Michael Schoen*
1573
1574 * Don't create instance writer methods for class attributes. Closes #7401 *Rick Olson*
1575
1576 * Docs: validations examples. #7343 *zackchandler*
1577
1578 * Add missing tests ensuring callbacks work with class inheritance. Closes #7339 *sandofsky*
1579
1580 * Fixtures use the table name and connection from set_fixture_class. #7330 *Anthony Eden*
1581
1582 * Remove useless code in #attribute_present? since 0 != blank?. Closes #7249 *Josh Susser*
1583
1584 * Fix minor doc typos. Closes #7157 *Josh Susser*
1585
1586 * Fix incorrect usage of #classify when creating the eager loading join statement. Closes #7044 *Josh Susser*
1587
1588 * SQLServer: quote table name in indexes query. #2928 *keithm@infused.org*

1591
1592 * Make sure sqlite3 driver closes open connections on disconnect *Rob Rasmussen*
1593
1594 * [DOC] clear up some ambiguity with the way has_and_belongs_to_many creates the default join table name. #7072 *Jeremy McAnally*
1595
1596 * change_column accepts :default => nil. Skip column options for primary keys. #6956, #7048 *Dan Manges, Jeremy Kemper*
1597
1598 * 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*
1599
1600 * Oracle: create_table takes a :sequence_name option to override the 'tablename_seq' default. #7000 *Michael Schoen*
1601
1602 * MySQL: retain SSL settings on reconnect. #6976 *randyv2*
1603
1604 * Apply scoping during initialize instead of create. Fixes setting of foreign key when using find_or_initialize_by with scoping. *Cody Fauser*
1605
1606 * SQLServer: handle [quoted] table names. #6635 *rrich*
1607
1608 * acts_as_nested_set works with single-table inheritance. #6030 *Josh Susser*
1609
1610 * PostgreSQL, Oracle: correctly perform eager finds with :limit and :order. #4668, #7021 *eventualbuddha, Michael Schoen*
1611
1612 * Pass a range in :conditions to use the SQL BETWEEN operator. #6974 *Dan Manges*
1613 Student.find(:all, :conditions => { :grade => 9..12 })
1614
1615 * Fix the Oracle adapter for serialized attributes stored in CLOBs. Closes #6825 *mschoen, tdfowler*
1616
1617 * [DOCS] Apply more documentation for ActiveRecord Reflection. Closes #4055 *Robby Russell*
1618
1619 * [DOCS] Document :allow_nil option of #validate_uniqueness_of. Closes #3143 *Caio Chassot*
1620
1621 * Bring the sybase adapter up to scratch for 1.2 release. *jsheets*
1622
1623 * Rollback new_record? and id when an exception is raised in a save callback. #6910 *Ben Curren, outerim*
1624
1625 * Pushing a record on an association collection doesn't unnecessarily load all the associated records. *Obie Fernandez, Jeremy Kemper*
1626
1627 * Oracle: fix connection reset failure. #6846 *leonlleslie*
1628
1629 * Subclass instantiation doesn't try to explicitly require the corresponding subclass. #6840 *leei, Jeremy Kemper*
1630
1631 * 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*
1632
1633 * 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*
1634
1635 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
1636
1637 * Add AssociationCollection#create! to be consistent with AssociationCollection#create when dealing with a foreign key that is a protected attribute *Cody Fauser*
1638
1639 * 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*
1640
1641 * Change fixture_path to a class inheritable accessor allowing test cases to have their own custom set of fixtures. #6672 *Zach Dennis*
1642
1643 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
1644
1645 * Simplify query_attribute by typecasting the attribute value and checking whether it's nil, false, zero or blank. #6659 *Jonathan Viney*
1646
1647 * 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*
1648
1649 * Run validations in the order they were declared. #6657 *obrie*
1650
1651 * 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*
1652
1653 * Simplify association proxy implementation by factoring construct_scope out of method_missing. #6643 *martin*
1654
1655 * Oracle: automatically detect the primary key. #6594 *vesaria, Michael Schoen*
1656
1657 * 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*
1658
1659 * Don't inspect unloaded associations. #2905 *lmarlow*
1660
1661 * SQLite: use AUTOINCREMENT primary key in >= 3.1.0. #6588, #6616 *careo, lukfugl*
1662
1663 * Cache inheritance_column. #6592 *Stefan Kaes*
1664
1665 * Firebird: decimal/numeric support. #6408 *macrnic*
1666
1667 * make add_order a tad faster. #6567 *Stefan Kaes*
1668
1669 * Find with :include respects scoped :order. #5850
1670
1671 * Support nil and Array in :conditions => { attr => value } hashes. #6548 *Assaf, Jeremy Kemper*
1672 find(:all, :conditions => { :topic_id => [1, 2, 3], :last_read => nil }
1673
1674 * 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*
1675
1676 * SQLite: fix calculations workaround, remove count(distinct) query rewrite, cleanup test connection scripts. *Jeremy Kemper*
1677
1678 * SQLite: count(distinct) queries supported in >= 3.2.6. #6544 *Bob Silva*
1679
1680 * Dynamically generate reader methods for serialized attributes. #6362 *Stefan Kaes*
1681
1682 * Deprecation: object transactions warning. *Jeremy Kemper*
1683
1684 * has_one :dependent => :nullify ignores nil associates. #4848, #6528 *bellis@deepthought.org, janovetz, Jeremy Kemper*
1685
1686 * 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*
1687
1688 * Make add_column use the options hash with the Sqlite Adapter. Closes #6464 *obrie*
1689
1690 * Document other options available to migration's add_column. #6419 *grg*
1691
1692 * MySQL: all_hashes compatibility with old MysqlRes class. #6429, #6601 *Jeremy Kemper*
1693
1694 * Fix has_many :through to add the appropriate conditions when going through an association using STI. Closes #5783. *Jonathan Viney*
1695
1696 * fix select_limited_ids_list issues in postgresql, retain current behavior in other adapters *Rick Olson*
1697
1698 * Restore eager condition interpolation, document it's differences *Rick Olson*
1699
1700 * 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*
1701
1702 * Add #delete support to has_many :through associations. Closes #6049 *Martin Landers*
1703
1704 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
1705
1706 * 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*
1707
1708 * 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*
1709
1710 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*
1711
1712 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
1713
1714 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
1715
1716 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
1717
1718 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
1719
1720 * 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*
1721
1722 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
1723
1724 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*
1725
1726 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*
1727
1728 * Duplicate the hash provided to AR::Base#to_xml to prevent unexpected side effects *Michael Koziarski*
1729
1730 * Add a :namespace option to AR::Base#to_xml *Michael Koziarski*
1731
1732 * Deprecation tests. Remove warnings for dynamic finders and for the foo_count method if it's also an attribute. *Jeremy Kemper*
1733
1734 * Mock Time.now for more accurate Touch mixin tests. #6213 *Dan Peterson*
1735
1736 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
1737
1738 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
1739
1740 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
1741
1742 * 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*
1743
1744 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
1745
1746 * Document validates_presences_of behavior with booleans: you probably want validates_inclusion_of :attr, :in => [true, false]. #2253 *Bob Silva*
1747
1748 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
1749
1750 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
1751
1752 * Deprecation: update docs. #5998 *Jakob Skjerning, Kevin Clark*
1753
1754 * Add some XmlSerialization tests for ActiveRecord *Rick Olson*
1755
1756 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
1757
1758 * Tighten rescue clauses. #5985 *james@grayproductions.net*
1759
1760 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
1761
1762 * 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*
1763
1764 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
1765
1766 * 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*
1767
1768 * SQLServer: fix eager association test. #5901 *Tom Ward*
1769
1770 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
1771
1772 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
1773
1774 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*
1775
1776 * MySQL: update test schema for MySQL 5 strict mode. #5861 *Tom Ward*
1777
1778 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
1779
1780 * 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*
1781
1782 * 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*
1783
1784 # Create a tagging to associate the post and tag.
1785 post.tags << Tag.find_by_name('old')
1786 post.tags.create! :name => 'general'
1787
1788 # Would have been:
1789 post.taggings.create!(:tag => Tag.find_by_name('finally')
1790 transaction do
1791 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
1792 end
1793
1794 * Cache nil results for :included has_one associations also. #5787 *Michael Schoen*
1795
1796 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
1797
1798 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
1799 Example: Invoice::Lineitem is given table name invoice_lineitems
1800
1801 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
1802 # people_active_last_name_index, people_active_deactivated_at_index

1819
1820 * Document find's :from option. Closes #5762. *andrew@redlinesoftware.com*
1821
1822 * 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*
1823
1824 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*

1887
1888 * 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*
1889
1890 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
1891
1892 * Minor tweak to improve performance of ActiveRecord::Base#to_param.
1893
1894 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
1895
1896 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
1897
1898 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
1899
1900 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
1901
1902 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
1903
1904 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
1905
1906 * 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*
1907 # Obtain an exclusive lock on person 1 so we can safely increment visits.
1908 Person.transaction do
1909 # select * from people where id=1 for update
1910 person = Person.find(1, :lock => true)
1911 person.visits += 1
1912 person.save!
1913 end
1914
1915 * 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*
1916
1917 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
1918
1919 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
1920
1921 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
1922
1923 * 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*
1924
1925 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
1926
1927 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
1928
1929 ...is the same as:
1930
1931 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
1932
1933 This makes it easier to pass in the options from a form or otherwise outside.

1945
1946 * 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*
1947
1948 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
1949

1951
1952 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
1953 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
1954 Foo.find(:first, :conditions => ['bar_id = ?', bar])
1955
1956 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
1957
1958 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
1959

1978
1979 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
1980
1981 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
1982

2079
2080 * Don't create instance writer methods for class attributes. *Rick Olson*

2083
2084 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
2085

2129
2130 * 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*
2131
2132 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
2133

2136
2137 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
2138
2139 * 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*
2140

2192
2193 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
2194

2196
2197 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*
2198
2199 * Duplicate the hash provided to AR::Base#to_xml to prevent unexpected side effects *Michael Koziarski*
2200
2201 * Add a :namespace option to AR::Base#to_xml *Michael Koziarski*
2202
2203 * Deprecation tests. Remove warnings for dynamic finders and for the foo_count method if it's also an attribute. *Jeremy Kemper*
2204
2205 * Mock Time.now for more accurate Touch mixin tests. #6213 *Dan Peterson*
2206
2207 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
2208
2209 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
2210
2211 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
2212
2213 * 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*
2214
2215 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
2216
2217 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
2218
2219 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
2220
2221 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
2222
2223 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
2224
2225 * 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*
2226
2227 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
2228
2229 * 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*
2230
2231 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
2232
2233 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
2234
2235 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*
2236
2237 * MySQL: update test schema for MySQL 5 strict mode. #5861 *Tom Ward*
2238
2239 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2240
2241 * 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*
2242
2243 * 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*
2244
2245 # Create a tagging to associate the post and tag.
2246 post.tags << Tag.find_by_name('old')
2247 post.tags.create! :name => 'general'
2248
2249 # Would have been:
2250 post.taggings.create!(:tag => Tag.find_by_name('finally')
2251 transaction do
2252 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
2253 end
2254
2255 * Cache nil results for :included has_one associations also. #5787 *Michael Schoen*
2256
2257 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
2258
2259 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
2260 Example: Invoice::Lineitem is given table name invoice_lineitems
2261
2262 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2263 # people_active_last_name_index, people_active_deactivated_at_index
2264 add_index :people, [:active, :last_name]
2265 add_index :people, [:active, :deactivated_at]
2266 remove_index :people, [:active, :last_name]
2267 remove_index :people, [:active, :deactivated_at]
2268
2269 WARNING: backward-incompatibility. Multicolumn indexes created before this
2270 revision were named using the first column name only. Now they're uniquely
2271 named using all indexed columns.
2272
2273 To remove an old multicolumn index, remove_index :table_name, :first_column
2274
2275 * Fix for deep includes on the same association. *richcollins@gmail.com*
2276
2277 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
2278
2279 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
2280
2281 * 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*
2282
2283 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
2284
2285 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
2286
2287 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
2288
2289 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
2290
2291 * Formally deprecate the deprecated finders. *Michael Koziarski*
2292
2293 * Formally deprecate rich associations. *Michael Koziarski*
2294
2295 * Fixed that default timezones for new / initialize should uphold utc setting #5709 *daniluk@yahoo.com*
2296
2297 * Fix announcement of very long migration names. #5722 *blake@near-time.com*
2298

2300
2301 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
2302

2304
2305 assert (Topic.exists?(:author_name => "David"))
2306 assert (Topic.exists?(:author_name => "Mary", :approved => true))
2307 assert (Topic.exists?(["parent_id = ?", 1]))
2308

2314
2315 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
2316
2317 * Allow #count through a has_many association to accept :include. *Dan Peterson*
2318
2319 * create_table rdoc: suggest :id => false for habtm join tables. *Zed Shaw*
2320
2321 * PostgreSQL: return array fields as strings. #4664 *Robby Russell*
2322
2323 * 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*
2324
2325 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2326
2327 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2328
2329 * 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*
2330
2331 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*
2332
2333 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2334
2335 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2336
2337 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2338
2339 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2340
2341 * 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*
2342
2343 * 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*
2344
2345 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2346
2347 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2348
2349 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2350
2351 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2352
2353 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2354
2355 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2356
2357 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2358
2359 * 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*
2360 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2361 Person.transaction do
2362 # select * from people where id=1 for update
2363 person = Person.find(1, :lock => true)
2364 person.visits += 1
2365 person.save!
2366 end
2367
2368 * 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*
2369
2370 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2371
2372 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2373
2374 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2375
2376 * 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*
2377
2378 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2379
2380 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2381
2382 ...is the same as:
2383
2384 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2385
2386 This makes it easier to pass in the options from a form or otherwise outside.
2387
2388
2389 * Fixed issues with BLOB limits, charsets, and booleans for Firebird #5194, #5191, #5189 *kennethkunz@gmail.com*

2396
2397 * Fixed that count distinct should use the selected column even when using :include #5251 *anna@wota.jp*
2398
2399 * 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*
2400
2401 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
2402
2403 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
2404
2405 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
2406 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
2407 Foo.find(:first, :conditions => ['bar_id = ?', bar])
2408
2409 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
2410
2411 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
2412
2413 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*
2414
2415 * Provide Association Extensions access to the instance that the association is being accessed from.
2416 Closes #4433 *Josh Susser*
2417
2418 * Update OpenBase adaterp's maintainer's email address. Closes #5176. *Derrick Spell*
2419
2420 * Add a quick note about :select and eagerly included associations. *Rick Olson*
2421
2422 * Add docs for the :as option in has_one associations. Closes #5144 *cdcarter@gmail.com*
2423
2424 * Fixed that has_many collections shouldn't load the entire association to do build or create *David Heinemeier Hansson*
2425
2426 * Added :allow_nil option for aggregations #5091 *Ian White*
2427
2428 * Fix Oracle boolean support and tests. Closes #5139. *Michael Schoen*
2429
2430 * 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*
2431
2432 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2433
2434 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2435
2436 * 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*
2437
2438 * Dates and times interpret empty strings as nil rather than 2000-01-01. #4830 *kajism@yahoo.com*

2600 * Fixed that MySQL enums should always be returned as strings #3501 *David Heinemeier Hansson*
2601
2602 * Change has_many :through to use the :source option to specify the source association. :class_name is now ignored. *Rick Olson*
2603
2604 class Connection < ActiveRecord::Base
2605 belongs_to :user
2606 belongs_to :channel
2607 end
2608
2609 class Channel < ActiveRecord::Base
2610 has_many :connections
2611 has_many :contacts, :through => :connections, :class_name => 'User' # OLD
2612 has_many :contacts, :through => :connections, :source => :user # NEW
2613 end
2614
2615 * 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*
2616
2617 * Allow overriding of find parameters in scoped has_many :through calls *Rick Olson*
2618
2619 In this example, :include => false disables the default eager association from loading. :select changes the standard
2620 select clause. :joins specifies a join that is added to the end of the has_many :through query.
2621
2622 class Post < ActiveRecord::Base
2623 has_many :tags, :through => :taggings, :include => :tagging do
2624 def add_joins_and_select
2625 find :all, :select => 'tags.*, authors.id as author_id', :include => false,
2626 :joins => 'left outer join posts on taggings.taggable_id = posts.id left outer join authors on posts.author_id = authors.id'
2627 end
2628 end
2629 end
2630
2631 * 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*
2632
2633 * Don't classify the has_one class when eager loading, it is already singular. Add tests. (closes #4117) *Jonathan Viney*
2634
2635 * Quit ignoring default :include options in has_many :through calls *Mark James*
2636
2637 * Allow has_many :through associations to find the source association by setting a custom class (closes #4307) *Jonathan Viney*
2638
2639 * Eager Loading support added for has_many :through => :has_many associations (see below). *Rick Olson*
2640
2641 * Allow has_many :through to work on has_many associations (closes #3864) [sco@scottraymond.net] Example:
2642
2643 class Firm < ActiveRecord::Base
2644 has_many :clients
2645 has_many :invoices, :through => :clients
2646 end
2647
2648 class Client < ActiveRecord::Base
2649 belongs_to :firm
2650 has_many :invoices
2651 end
2652
2653 class Invoice < ActiveRecord::Base
2654 belongs_to :client
2655 end
2656
2657 * Raise error when trying to select many polymorphic objects with has_many :through or :include (closes #4226) *Josh Susser*
2658
2659 * Fixed has_many :through to include :conditions set on the :through association. closes #4020 *Jonathan Viney*
2660
2661 * 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*
2662
2663 * SQL Server adapter gets some love #4298 *Ryan Tomayko*
2664
2665 * 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*
2666
2667 * 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):
2668
2669 Author.find(:all, :include => { :posts => :special_comments }, :order => 'special_comments.body')
2670
2671 * Add AbstractAdapter#table_alias_for to create table aliases according to the rules of the current adapter. *Rick Olson*
2672
2673 * 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*
2674
2675 * Remove broken attempts at handling columns with a default of 'now()' in the postgresql adapter. #2257 *Michael Koziarski*
2676
2677 * 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*
2678
2679 * Fixed that Migration#execute would have the table name prefix appended to its query #4110 *mark.imbriaco@pobox.com*
2680
2681 * Make all tinyint(1) variants act like boolean in mysql (tinyint(1) unsigned, etc.) *Jamis Buck*
2682
2683 * Use association's :conditions when eager loading. [Jeremy Evans] #4144
2684
2685 * Alias the has_and_belongs_to_many join table on eager includes. #4106 *Jeremy Evans*
2686
2687 This statement would normally error because the projects_developers table is joined twice, and therefore joined_on would be ambiguous.
2688
2689 Developer.find(:all, :include => {:projects => :developers}, :conditions => 'join_project_developers.joined_on IS NOT NULL')
2690
2691 * Oracle adapter gets some love #4230 *Michael Schoen*
2692
2693 * Changes :text to CLOB rather than BLOB [Moses Hohman]
2694 * Fixes an issue with nil numeric length/scales (several)
2695 * Implements support for XMLTYPE columns [wilig / Kubo Takehiro]
2696 * Tweaks a unit test to get it all green again
2697 * Adds support for #current_database
2698
2699 * Added Base.abstract_class? that marks which classes are not part of the Active Record hierarchy #3704 *Rick Olson*
2700
2701 class CachedModel < ActiveRecord::Base
2702 self.abstract_class = true
2703 end
2704
2705 class Post < CachedModel
2706 end
2707
2708 CachedModel.abstract_class?
2709 => true
2710
2711 Post.abstract_class?
2712 => false
2713
2714 Post.base_class
2715 => Post
2716
2717 Post.table_name
2718 => 'posts'
2719
2720 * Allow :dependent options to be used with polymorphic joins. #3820 *Rick Olson*
2721
2722 class Foo < ActiveRecord::Base
2723 has_many :attachments, :as => :attachable, :dependent => :delete_all
2724 end
2725
2726 * Nicer error message on has_many :through when :through reflection can not be found. #4042 *court3nay*
2727
2728 * Upgrade to Transaction::Simple 1.3 *Jamis Buck*
2729
2730 * Catch FixtureClassNotFound when using instantiated fixtures on a fixture that has no ActiveRecord model *Rick Olson*
2731
2732 * Allow ordering of calculated results and/or grouped fields in calculations *solo@gatelys.com*
2733
2734 * Make ActiveRecord::Base#save! return true instead of nil on success. #4173 *johan@johansorensen.com*
2735
2736 * Dynamically set allow_concurrency. #4044 *Stefan Kaes*
2737
2738 * Added Base#to_xml that'll turn the current record into a XML representation [David Heinemeier Hansson]. Example:
2739
2740 topic.to_xml
2741
2742 ...returns:
2743
2744 <?xml version="1.0" encoding="UTF-8"?>

2801
2802 * Allow :counter_cache to take a column name for custom counter cache columns *Jamis Buck*
2803
2804 * Documentation fixes for :dependent *robby@planetargon.com*
2805
2806 * Stop the MySQL adapter crashing when views are present. #3782 *Jonathan Viney*
2807
2808 * Don't classify the belongs_to class, it is already singular #4117 *keithm@infused.org*
2809
2810 * 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*
2811
2812 * Fix quoting of inheritance column for STI eager loading #4098 *Jonathan Viney <jonathan@bluewire.net.nz>*
2813
2814 * Added smarter table aliasing for eager associations for multiple self joins #3580 *Rick Olson*
2815
2816 * The first time a table is referenced in a join, no alias is used.
2817 * After that, the parent class name and the reflection name are used.
2818
2819 Tree.find(:all, :include => :children) # LEFT OUTER JOIN trees AS tree_children ...
2820
2821 * Any additional join references get a numerical suffix like '_2', '_3', etc.
2822
2823 * 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.
2824
2825 * 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:
2826
2827 # cascaded in two levels
2828 >> Author.find(:all, :include=>{:posts=>:comments})
2829 => authors
2830 +- posts
2831 +- comments
2832
2833 # cascaded in two levels and normal association
2834 >> Author.find(:all, :include=>[{:posts=>:comments}, :categorizations])
2835 => authors
2836 +- posts
2837 +- comments
2838 +- categorizations
2839
2840 # cascaded in two levels with two has_many associations
2841 >> Author.find(:all, :include=>{:posts=>[:comments, :categorizations]})
2842 => authors
2843 +- posts
2844 +- comments
2845 +- categorizations
2846
2847 # cascaded in three levels
2848 >> Company.find(:all, :include=>{:groups=>{:members=>{:favorites}}})
2849 => companies
2850 +- groups
2851 +- members
2852 +- favorites
2853
2854 * Make counter cache work when replacing an association #3245 *eugenol@gmail.com*
2855
2856 * Make migrations verbose *Jamis Buck*
2857
2858 * Make counter_cache work with polymorphic belongs_to *Jamis Buck*
2859
2860 * Fixed that calling HasOneProxy#build_model repeatedly would cause saving to happen #4058 *anna@wota.jp*
2861
2862 * 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:
2863
2864 * Does not support DATE SQL column types; use DATETIME instead.
2865 * Date columns on HABTM join tables are returned as String, not Time.
2866 * Insertions are potentially broken for :polymorphic join tables
2867 * BLOB column access not yet fully supported
2868
2869 * Clear stale, cached connections left behind by defunct threads. *Jeremy Kemper*
2870
2871 * CHANGED DEFAULT: set ActiveRecord::Base.allow_concurrency to false. Most AR usage is in single-threaded applications. *Jeremy Kemper*
2872
2873 * Renamed the "oci" adapter to "oracle", but kept the old name as an alias #4017 *Michael Schoen*
2874
2875 * 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*
2876
2877 * Speed up class -> connection caching and stale connection verification. #3979 *Stefan Kaes*
2878
2879 * Add set_fixture_class to allow the use of table name accessors with models which use set_table_name. *Kevin Clark*
2880
2881 * Added that fixtures to placed in subdirectories of the main fixture files are also loaded #3937 *dblack@wobblini.net*
2882
2883 * Define attribute query methods to avoid method_missing calls. #3677 *Jonathan Viney*
2884
2885 * 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*
2886
2887 * Added support for nested scopes #3407 [anna@wota.jp]. Examples:
2888
2889 Developer.with_scope(:find => { :conditions => "salary > 10000", :limit => 10 }) do
2890 Developer.find(:all) # => SELECT * FROM developers WHERE (salary > 10000) LIMIT 10
2891
2892 # inner rule is used. (all previous parameters are ignored)
2893 Developer.with_exclusive_scope(:find => { :conditions => "name = 'Jamis'" }) do
2894 Developer.find(:all) # => SELECT * FROM developers WHERE (name = 'Jamis')
2895 end
2896
2897 # parameters are merged
2898 Developer.with_scope(:find => { :conditions => "name = 'Jamis'" }) do
2899 Developer.find(:all) # => SELECT * FROM developers WHERE (( salary > 10000 ) AND ( name = 'Jamis' )) LIMIT 10
2900 end
2901 end
2902
2903 * Fixed db2 connection with empty user_name and auth options #3622 *phurley@gmail.com*
2904
2905 * Fixed validates_length_of to work on UTF-8 strings by using characters instead of bytes #3699 *Masao Mutoh*
2906
2907 * Fixed that reflections would bleed across class boundaries in single-table inheritance setups #3796 *Lars Pind*
2908
2909 * 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:
2910
2911 Person.average :age
2912 Person.minimum :age
2913 Person.maximum :age
2914 Person.sum :salary, :group => :last_name
2915
2916 * Renamed Errors#count to Errors#size but kept an alias for the old name (and included an alias for length too) #3920 *Luke Redpath*
2917
2918 * Reflections don't attempt to resolve module nesting of association classes. Simplify type computation. *Jeremy Kemper*
2919
2920 * 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*
2921
2922 * Fixed that the schema_info table used by ActiveRecord::Schema.define should respect table pre- and suffixes #3834 *rubyonrails@atyp.de*
2923
2924 * 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*
2925
2926 * Correct syntax error in mysql DDL, and make AAACreateTablesTest run first *Bob Silva*
2927
2928 * Allow :include to be used with has_many :through associations #3611 *Michael Schoen*
2929
2930 * PostgreSQL: smarter schema dumps using pk_and_sequence_for(table). #2920 *Blair Zajac*
2931
2932 * SQLServer: more compatible limit/offset emulation. #3779 *Tom Ward*
2933
2934 * Polymorphic join support for has_one associations (has_one :foo, :as => :bar) #3785 *Rick Olson*
2935
2936 * PostgreSQL: correctly parse negative integer column defaults. #3776 *bellis@deepthought.org*
2937
2938 * Fix problems with count when used with :include *Jeremy Hopple and Kevin Clark*
2939
2940 * ActiveRecord::RecordInvalid now states which validations failed in its default error message *Tobias Lütke*
2941
2942 * Using AssociationCollection#build with arrays of hashes should call build, not create *David Heinemeier Hansson*
2943
2944 * Remove definition of reloadable? from ActiveRecord::Base to make way for new Reloadable code. *Nicholas Seckar*
2945
2946 * 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*
2947
2948 * Support the :column option for remove_index with the PostgreSQL adapter. #3661 *Shugo Maeda*
2949
2950 * Add documentation for add_index and remove_index. #3600 *Manfred Stienstra <m.stienstra@fngtps.com>*
2951
2952 * If the OCI library is not available, raise an exception indicating as much. #3593 *Michael Schoen*
2953
2954 * Add explicit :order in finder tests as postgresql orders results differently by default. #3577. *Rick Olson*
2955
2956 * Make dynamic finders honor additional passed in :conditions. #3569 *Oleg Pudeyev <pudeyo@rpi.edu>, Marcel Molina Jr.*
2957
2958 * Show a meaningful error when the DB2 adapter cannot be loaded due to missing dependencies. *Nicholas Seckar*
2959
2960 * Make .count work for has_many associations with multi line finder sql *Michael Schoen*
2961
2962 * Add AR::Base.base_class for querying the ancestor AR::Base subclass *Jamis Buck*
2963
2964 * Allow configuration of the column used for optimistic locking *wilsonb@gmail.com*
2965
2966 * Don't hardcode 'id' in acts as list. *ror@philippeapril.com*
2967
2968 * Fix date errors for SQLServer in association tests. #3406 *Kevin Clark*
2969
2970 * Escape database name in MySQL adapter when creating and dropping databases. #3409 *anna@wota.jp*
2971
2972 * Disambiguate table names for columns in validates_uniqueness_of's WHERE clause. #3423 *alex.borovsky@gmail.com*
2973
2974 * .with_scope imposed create parameters now bypass attr_protected *Tobias Lütke*
2975
2976 * Don't raise an exception when there are more keys than there are named bind variables when sanitizing conditions. *Marcel Molina Jr.*
2977
2978 * Multiple enhancements and adjustments to DB2 adaptor. #3377 *contact@maik-schmidt.de*
2979
2980 * Sanitize scoped conditions. *Marcel Molina Jr.*
2981
2982 * 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*
2983
2984 * 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*
2985
2986 * 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*
2987
2988 * Fixed that saving a model with multiple habtm associations would only save the first one. #3244 *yanowitz-rubyonrails@quantumfoam.org, Florian Weber*
2989
2990 * Fix change_column to work with PostgreSQL 7.x and 8.x. #3141 *wejn@box.cz, Rick Olson, Scott Barron*

2993
2994 * made method missing delegation to class methods on relation target work on :through associations. *Tobias Lütke*
2995
2996 * made .find() work on :through relations. *Tobias Lütke*
2997
2998 * Fix typo in association docs. #3296. *Blair Zajac*
2999
3000 * Fixed :through relations when using STI inherited classes would use the inherited class's name as foreign key on the join model *Tobias Lütke*
3001

3006 * MySQL: allow encoding option for mysql.rb driver. *Jeremy Kemper*
3007
3008 * Added option inheritance for find calls on has_and_belongs_to_many and has_many assosociations [David Heinemeier Hansson]. Example:
3009
3010 class Post
3011 has_many :recent_comments, :class_name => "Comment", :limit => 10, :include => :author
3012 end
3013
3014 post.recent_comments.find(:all) # Uses LIMIT 10 and includes authors
3015 post.recent_comments.find(:all, :limit => nil) # Uses no limit but include authors
3016 post.recent_comments.find(:all, :limit => nil, :include => nil) # Uses no limit and doesn't include authors
3017
3018 * Added option to specify :group, :limit, :offset, and :select options from find on has_and_belongs_to_many and has_many assosociations *David Heinemeier Hansson*

3033
3034 * MySQL: more robust test for nullified result hashes. #3124 *Stefan Kaes*
3035
