2011-11-04 Convert CHANGELOGs to Markdown format.
109 ## Rails 3.1.1 (October 7, 2011) ##
110
111 * Raise an exception if the primary key of a model in an association is needed
112 but unknown. Fixes #3207.
113
114 *Jon Leighton*
115
116 * Add deprecation for the preload_associations method. Fixes #3022.
117
118 *Jon Leighton*
119
120 * Don't require a DB connection when loading a model that uses set_primary_key. GH #2807.
121
122 *Jon Leighton*
123
124 * Fix using select() with a habtm association, e.g. Person.friends.select(:name). GH #3030 and
125 \#2923.
126
127 *Hendy Tanata*
128
129 * Fix belongs_to polymorphic with custom primary key on target. GH #3104.
130
131 *Jon Leighton*
132
133 * CollectionProxy#replace should change the DB records rather than just mutating the array.
134 Fixes #3020.
135
136 *Jon Leighton*
137
138 * LRU cache in mysql and sqlite are now per-process caches.
139
140 * lib/active_record/connection_adapters/mysql_adapter.rb: LRU cache
141 keys are per process id.
142 * lib/active_record/connection_adapters/sqlite_adapter.rb: ditto
143
144 *Aaron Patterson*
145
146 * Database adapters use a statement pool for limiting the number of open
147 prepared statments on the database. The limit defaults to 1000, but can
148 be adjusted in your database config by changing 'statement_limit'.
149
150 * Fix clash between using 'preload', 'joins' or 'eager_load' in a default scope and including the
151 default scoped model in a nested through association. (GH #2834.) *Jon Leighton*
152
153 * Ensure we are not comparing a string with a symbol in HasManyAssociation#inverse_updates_counter_cache?.
154 Fixes GH #2755, where a counter cache could be decremented twice as far as it was supposed to be.
155
156 *Jon Leighton*
157
158 * Don't send any queries to the database when the foreign key of a belongs_to is nil. Fixes
159 GH #2828. *Georg Friedrich*
160
161 * Fixed find_in_batches method to not include order from default_scope. See GH #2832 *Arun Agrawal*
162
163 * Don't compute table name for abstract classes. Fixes problem with setting the primary key
164 in an abstract class. See GH #2791. *Akira Matsuda*
165
166 * Psych errors with poor yaml formatting are proxied. Fixes GH #2645 and
167 GH #2731
168
169 * Use the LIMIT word with the methods #last and #first. Fixes GH #2783 *Damien Mathieu*
170
171 ## Rails 3.1.0 (August 30, 2011) ##
172
173 * Add a proxy_association method to association proxies, which can be called by association
174 extensions to access information about the association. This replaces proxy_owner etc with
175 proxy_association.owner.
176
177 *Jon Leighton*
178
179 * 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*
180
181 * Deprecated the AssociationCollection constant. CollectionProxy is now the appropriate constant
182 to use, though be warned that this is not really a public API.
183
184 This should solve upgrade problems with the will_paginate plugin (and perhaps others). Thanks
185 Paul Battley for reporting.
186
187 *Jon Leighton*
188
189 * ActiveRecord::MacroReflection::AssociationReflection#build_record has a new method signature.
190
191 Before: def build_association(*options)
192 After: def build_association(*options, &block)
193
194 Users who are redefining this method to extend functionality should ensure that the block is
195 passed through to ActiveRecord::Base#new.
196
197 This change is necessary to fix https://github.com/rails/rails/issues/1842.
198
199 A deprecation warning and workaround has been added to 3.1, but authors will need to update
200 their code for it to work correctly in 3.2.
201
202 *Jon Leighton*
203
204 * AR#pluralize_table_names can be used to singularize/pluralize table name of an individual model:
205
206 class User < ActiveRecord::Base
207 self.pluralize_table_names = false
208 end
209
210 Previously this could only be set globally for all models through ActiveRecord::Base.pluralize_table_names. *Guillermo Iguaran*
211
212 * Add block setting of attributes to singular associations:
213
214 class User < ActiveRecord::Base
215 has_one :account
216 end
217
218 user.build_account{ |a| a.credit_limit => 100.0 }
219
220 The block is called after the instance has been initialized. *Andrew White*
221
222 * 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*
223
224 * CSV Fixtures are deprecated and support will be removed in Rails 3.2.0
225
226 * AR#new, AR#create, AR#create!, AR#update_attributes and AR#update_attributes! all accept a second hash as option that allows you
227 to specify which role to consider when assigning attributes. This is built on top of ActiveModel's
228 new mass assignment capabilities:
229
230 class Post < ActiveRecord::Base
231 attr_accessible :title
232 attr_accessible :title, :published_at, :as => :admin
233 end
234
235 Post.new(params[:post], :as => :admin)
236
237 assign_attributes() with similar API was also added and attributes=(params, guard) was deprecated.
238
239 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.
240
241 *Josh Kalderimis*
242
243 * default_scope can take a block, lambda, or any other object which responds to `call` for lazy
244 evaluation:
245
246 default_scope { ... }
247 default_scope lambda { ... }
248 default_scope method(:foo)
249
250 This feature was originally implemented by Tim Morgan, but was then removed in favour of
251 defining a 'default_scope' class method, but has now been added back in by Jon Leighton.
252 The relevant lighthouse ticket is #1812.
253
254 * Default scopes are now evaluated at the latest possible moment, to avoid problems where
255 scopes would be created which would implicitly contain the default scope, which would then
256 be impossible to get rid of via Model.unscoped.
257
258 Note that this means that if you are inspecting the internal structure of an
259 ActiveRecord::Relation, it will *not* contain the default scope, though the resulting
260 query will do. You can get a relation containing the default scope by calling
261 ActiveRecord#with_default_scope, though this is not part of the public API.
262
263 *Jon Leighton*
264
265 * If you wish to merge default scopes in special ways, it is recommended to define your default
266 scope as a class method and use the standard techniques for sharing code (inheritance, mixins,
267 etc.):
268
269 class Post < ActiveRecord::Base
270 def self.default_scope
271 where(:published => true).where(:hidden => false)
272 end
273 end
274
275 *Jon Leighton*
276
277 * PostgreSQL adapter only supports PostgreSQL version 8.2 and higher.
278
279 * ConnectionManagement middleware is changed to clean up the connection pool
280 after the rack body has been flushed.
281
282 * Added an update_column method on ActiveRecord. This new method updates a given attribute on an object, skipping validations and callbacks.
283 It is recommended to use #update_attribute unless you are sure you do not want to execute any callback, including the modification of
284 the updated_at column. It should not be called on new records.
285 Example:
286
287 User.first.update_column(:name, "sebastian") # => true
288
289 *Sebastian Martinez*
290
291 * Associations with a :through option can now use *any* association as the
292 through or source association, including other associations which have a
293 :through option and has_and_belongs_to_many associations
294
295 *Jon Leighton*
296
297 * The configuration for the current database connection is now accessible via
298 ActiveRecord::Base.connection_config. *fxn*
299
300 * limits and offsets are removed from COUNT queries unless both are supplied.
301 For example:
302
303 People.limit(1).count # => 'SELECT COUNT(*) FROM people'
304 People.offset(1).count # => 'SELECT COUNT(*) FROM people'
305 People.limit(1).offset(1).count # => 'SELECT COUNT(*) FROM people LIMIT 1 OFFSET 1'
306
307 *lighthouse #6262*
308
309 * ActiveRecord::Associations::AssociationProxy has been split. There is now an Association class
310 (and subclasses) which are responsible for operating on associations, and then a separate,
311 thin wrapper called CollectionProxy, which proxies collection associations.
312
313 This prevents namespace pollution, separates concerns, and will allow further refactorings.
314
315 Singular associations (has_one, belongs_to) no longer have a proxy at all. They simply return
316 the associated record or nil. This means that you should not use undocumented methods such
317 as bob.mother.create - use bob.create_mother instead.
318
319 *Jon Leighton*
320
321 * Make has_many :through associations work correctly when you build a record and then save it. This
322 requires you to set the :inverse_of option on the source reflection on the join model, like so:
323
324 class Post < ActiveRecord::Base
325 has_many :taggings
326 has_many :tags, :through => :taggings
327 end
328
329 class Tagging < ActiveRecord::Base
330 belongs_to :post
331 belongs_to :tag, :inverse_of => :tagging # :inverse_of must be set!
332 end
333
334 class Tag < ActiveRecord::Base
335 has_many :taggings
336 has_many :posts, :through => :taggings
337 end
338
339 post = Post.first
340 tag = post.tags.build :name => "ruby"
341 tag.save # will save a Taggable linking to the post
342
343 *Jon Leighton*
344
345 * Support the :dependent option on has_many :through associations. For historical and practical
346 reasons, :delete_all is the default deletion strategy employed by association.delete(*records),
347 despite the fact that the default strategy is :nullify for regular has_many. Also, this only
348 works at all if the source reflection is a belongs_to. For other situations, you should directly
349 modify the through association.
350
351 *Jon Leighton*
352
353 * Changed the behaviour of association.destroy for has_and_belongs_to_many and has_many :through.
354 From now on, 'destroy' or 'delete' on an association will be taken to mean 'get rid of the link',
355 not (necessarily) 'get rid of the associated records'.
356
357 Previously, has_and_belongs_to_many.destroy(*records) would destroy the records themselves. It
358 would not delete any records in the join table. Now, it deletes the records in the join table.
359
360 Previously, has_many_through.destroy(*records) would destroy the records themselves, and the
361 records in the join table. [Note: This has not always been the case; previous version of Rails
362 only deleted the records themselves.] Now, it destroys only the records in the join table.
363
364 Note that this change is backwards-incompatible to an extent, but there is unfortunately no
365 way to 'deprecate' it before changing it. The change is being made in order to have
366 consistency as to the meaning of 'destroy' or 'delete' across the different types of associations.
367
368 If you wish to destroy the records themselves, you can do records.association.each(&:destroy)
369
370 *Jon Leighton*
371
372 * 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*
373
374 Example:
375
376 change_table(:users, :bulk => true) do |t|
377 t.string :company_name
378 t.change :birthdate, :datetime
379 end
380
381 This will now result in:
382
383 ALTER TABLE `users` ADD COLUMN `company_name` varchar(255), CHANGE `updated_at` `updated_at` datetime DEFAULT NULL
384
385 * Removed support for accessing attributes on a has_and_belongs_to_many join table. This has been
386 documented as deprecated behaviour since April 2006. Please use has_many :through instead.
387 *Jon Leighton*
388
389 * Added a create_association! method for has_one and belongs_to associations. *Jon Leighton*
390
391 * Migration files generated from model and constructive migration generators
392 (for example, add_name_to_users) use the reversible migration's `change`
393 method instead of the ordinary `up` and `down` methods. *Prem Sichanugrist*
394
395 * Removed support for interpolating string SQL conditions on associations. Instead, you should
396 use a proc, like so:
397
398 Before:
399
400 has_many :things, :conditions => 'foo = #{bar}'
401
402 After:
403
404 has_many :things, :conditions => proc { "foo = #{bar}" }
405
406 Inside the proc, 'self' is the object which is the owner of the association, unless you are
407 eager loading the association, in which case 'self' is the class which the association is within.
408
409 You can have any "normal" conditions inside the proc, so the following will work too:
410
411 has_many :things, :conditions => proc { ["foo = ?", bar] }
412
413 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
414 'record' to get the record being inserted or deleted. This is now passed as an argument to
415 the proc.
416
417 * Added ActiveRecord::Base#has_secure_password (via ActiveModel::SecurePassword) to encapsulate dead-simple password usage with BCrypt encryption and salting [DHH]. Example:
418
419 # Schema: User(name:string, password_digest:string, password_salt:string)
420 class User < ActiveRecord::Base
421 has_secure_password
422 end
423
424 user = User.new(:name => "david", :password => "", :password_confirmation => "nomatch")
425 user.save # => false, password required
426 user.password = "mUc3m00RsqyRe"
427 user.save # => false, confirmation doesn't match
428 user.password_confirmation = "mUc3m00RsqyRe"
429 user.save # => true
430 user.authenticate("notright") # => false
431 user.authenticate("mUc3m00RsqyRe") # => user
432 User.find_by_name("david").try(:authenticate, "notright") # => nil
433 User.find_by_name("david").try(:authenticate, "mUc3m00RsqyRe") # => user
434
435
436 * When a model is generated add_index is added by default for belongs_to or references columns
437
438 rails g model post user:belongs_to will generate the following:
439
440 class CreatePosts < ActiveRecord::Migration
441 def change
442 create_table :posts do |t|
443 t.belongs_to :user
444 t.timestamps
445 end
446 add_index :posts, :user_id
447 end
448 end
449
450 *Santiago Pastorino*
451
452 * Setting the id of a belongs_to object will update the reference to the
453 object. *#2989 state:resolved*
454
455 * ActiveRecord::Base#dup and ActiveRecord::Base#clone semantics have changed
456 to closer match normal Ruby dup and clone semantics.
457
458 * Calling ActiveRecord::Base#clone will result in a shallow copy of the record,
459 including copying the frozen state. No callbacks will be called.
460
461 * Calling ActiveRecord::Base#dup will duplicate the record, including calling
462 after initialize hooks. Frozen state will not be copied, and all associations
463 will be cleared. A duped record will return true for new_record?, have a nil
464 id field, and is saveable.
465
466 * Migrations can be defined as reversible, meaning that the migration system
467 will figure out how to reverse your migration. To use reversible migrations,
468 just define the "change" method. For example:
469
470 class MyMigration < ActiveRecord::Migration
471 def change
472 create_table(:horses) do
473 t.column :content, :text
474 t.column :remind_at, :datetime
475 end
476 end
477 end
478
479 Some things cannot be automatically reversed for you. If you know how to
480 reverse those things, you should define 'up' and 'down' in your migration. If
481 you define something in `change` that cannot be reversed, an
482 IrreversibleMigration exception will be raised when going down.
483
484 * Migrations should use instance methods rather than class methods:
485 class FooMigration < ActiveRecord::Migration
486 def up
487 ...
488 end
489 end
490
491 *Aaron Patterson*
492
493 * has_one maintains the association with separate after_create/after_update instead
494 of a single after_save. *fxn*
495
496 * The following code:
497
498 Model.limit(10).scoping { Model.count }
499
500 now generates the following SQL:
501
502 SELECT COUNT(*) FROM models LIMIT 10
503
504 This may not return what you want. Instead, you may with to do something
505 like this:
506
507 Model.limit(10).scoping { Model.all.size }
508
509 *Aaron Patterson*

512 ## Rails 3.0.7 (April 18, 2011) ##
513
514 * Destroying records via nested attributes works independent of reject_if LH #6006 *Durran Jordan*
515
516 * Delegate any? and many? to Model.scoped for consistency *Andrew White*
517
518 * Quote the ORDER BY clause in batched finds - fixes #6620 *Andrew White*
519
520 * Change exists? so records are not instantiated - fixes #6127. This prevents after_find
521 and after_initialize callbacks being triggered when checking for record existence.
522 *Andrew White*
523
524 * Fix performance bug with attribute accessors which only occurred on Ruby 1.8.7, and ensure we
525 cache type-casted values when the column returned from the db contains non-standard chars.
526 *Jon Leighton*
527
528 * Fix a performance regression introduced here 86acbf1cc050c8fa8c74a10c735e467fb6fd7df8
529 related to read_attribute method *Stian Grytøyr*
530

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

826
827 * Added that ActiveRecord::Base.exists? can be called with no arguments #1817 *Scott Taylor*
828
829 * Add Support for updating deeply nested models from a single form. #1202 *Eloy Duran*
830
831 class Book < ActiveRecord::Base
832 has_one :author
833 has_many :pages
834
835 accepts_nested_attributes_for :author, :pages
836 end
837
838 * Make after_save callbacks fire only if the record was successfully saved. #1735 *Michael Lovitt*
839
840 Previously the callbacks would fire if a before_save cancelled saving.
841
842 * Support nested transactions using database savepoints. #383 *Jonathan Viney, Hongli Lai*
843
844 * Added dynamic scopes ala dynamic finders #1648 *Yaroslav Markin*
845
846 * Fixed that ActiveRecord::Base#new_record? should return false (not nil) for existing records #1219 *Yaroslav Markin*
847
848 * I18n the word separator for error messages. Introduces the activerecord.errors.format.separator translation key. #1294 *Akira Matsuda*
849
850 * Add :having as a key to find and the relevant associations. *Emilio Tagua*
851
852 * Added default_scope to Base #1381 [Paweł Kondzior]. Example:
853
854 class Person < ActiveRecord::Base
855 default_scope :order => 'last_name, first_name'
856 end
857
858 class Company < ActiveRecord::Base
859 has_many :people
860 end
861
862 Person.all # => Person.find(:all, :order => 'last_name, first_name')
863 Company.find(1).people # => Person.find(:all, :order => 'last_name, first_name', :conditions => { :company_id => 1 })
864
865
866 ## 2.2.1 RC2 (November 14th, 2008) ##
867
868 * Ensure indices don't flip order in schema.rb #1266 *Jordi Bunster*
869
870 * Fixed that serialized strings should never be type-casted (i.e. turning "Yes" to a boolean) #857 *Andreas Korth*
871
872
873 ## 2.2.0 RC1 (October 24th, 2008) ##
874
875 * Skip collection ids reader optimization if using :finder_sql *Jeremy Kemper*
876
877 * Add Model#delete instance method, similar to Model.delete class method. #1086 *Hongli Lai (Phusion)*
878
879 * MySQL: cope with quirky default values for not-null text columns. #1043 *Frederick Cheung*
880
881 * Multiparameter attributes skip time zone conversion for time-only columns [#1030 state:resolved] *Geoff Buesing*
882
883 * Base.skip_time_zone_conversion_for_attributes uses class_inheritable_accessor, so that subclasses don't overwrite Base [#346 state:resolved] *Emilio Tagua*
884
885 * Added find_last_by dynamic finder #762 *Emilio Tagua*
886
887 * Internal API: configurable association options and build_association method for reflections so plugins may extend and override. #985 *Hongli Lai (Phusion)*
888
889 * Changed benchmarks to be reported in milliseconds *David Heinemeier Hansson*
890
891 * Connection pooling. #936 *Nick Sieger*
892
893 * Merge scoped :joins together instead of overwriting them. May expose scoping bugs in your code! #501 *Andrew White*
894
895 * 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*
896
897 * Transactional migrations for databases which support them. #834 *divoxx, Adam Wiggins, Tarmo Tänav*
898
899 * Set config.active_record.timestamped_migrations = false to have migrations with numeric prefix instead of UTC timestamp. #446. *Andrew Stone, Nik Wakelin*
900
901 * change_column_default preserves the not-null constraint. #617 *Tarmo Tänav*
902
903 * Fixed that create database statements would always include "DEFAULT NULL" (Nick Sieger) *#334*
904
905 * Add :tokenizer option to validates_length_of to specify how to split up the attribute string. #507. [David Lowenfels] Example :
906
907 \# Ensure essay contains at least 100 words.
908 validates_length_of :essay, :minimum => 100, :too_short => "Your essay must be at least %d words."), :tokenizer => lambda {|str| str.scan(/\w+/) }
909
910 * Allow conditions on multiple tables to be specified using hash. [Pratik Naik]. Example:
911
912 User.all :joins => :items, :conditions => { :age => 10, :items => { :color => 'black' } }
913 Item.first :conditions => { :items => { :color => 'red' } }
914
915 * Always treat integer :limit as byte length. #420 *Tarmo Tänav*
916
917 * Partial updates don't update lock_version if nothing changed. #426 *Daniel Morrison*
918
919 * Fix column collision with named_scope and :joins. #46 *Duncan Beevers, Mark Catley*
920
921 * db:migrate:down and :up update schema_migrations. #369 *Michael Raidel, RaceCondition*
922
923 * PostgreSQL: support :conditions => [':foo::integer', { :foo => 1 }] without treating the ::integer typecast as a bind variable. *Tarmo Tänav*
924
925 * MySQL: rename_column preserves column defaults. #466 *Diego Algorta*
926
927 * Add :from option to calculations. #397 *Ben Munat*
928
929 * Add :validate option to associations to enable/disable the automatic validation of associated models. Resolves #301. *Jan De Poorter*
930
931 * PostgreSQL: use 'INSERT ... RETURNING id' for 8.2 and later. *Jeremy Kemper*
932
933 * Added SQL escaping for :limit and :offset in MySQL *Jonathan Wiess*
934
935
936 ## 2.1.0 (May 31st, 2008) ##
937
938 * Add ActiveRecord::Base.sti_name that checks ActiveRecord::Base#store_full_sti_class? and returns either the full or demodulized name. *Rick Olson*
939
940 * Add first/last methods to associations/named_scope. Resolved #226. *Ryan Bates*
941
942 * Added SQL escaping for :limit and :offset #288 *Aaron Bedra, Steven Bristol, Jonathan Wiess*
943
944 * Added first/last methods to associations/named_scope. Resolved #226. *Ryan Bates*
945
946 * Ensure hm:t preloading honours reflection options. Resolves #137. *Frederick Cheung*
947
948 * Added protection against duplicate migration names (Aslak Hellesøy) *#112*
949
950 * 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*
951
952 * 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*
953
954 * Added change_table for migrations (Jeff Dean) [#71]. Example:
955
956 change_table :videos do |t|
957 t.timestamps # adds created_at, updated_at
958 t.belongs_to :goat # adds goat_id integer
959 t.string :name, :email, :limit => 20 # adds name and email both with a 20 char limit
960 t.remove :name, :email # removes the name and email columns
961 end
962
963 * Fixed has_many :through .create with no parameters caused a "can't dup NilClass" error (Steven Soroka) *#85*
964
965 * Added block-setting of attributes for Base.create like Base.new already has (Adam Meehan) *#39*
966
967 * Fixed that pessimistic locking you reference the quoted table name (Josh Susser) *#67*
968
969 * Fixed that change_column should be able to use :null => true on a field that formerly had false [Nate Wiger] *#26*
970
971 * Added that the MySQL adapter should map integer to either smallint, int, or bigint depending on the :limit just like PostgreSQL *David Heinemeier Hansson*
972
973 * Change validates_uniqueness_of :case_sensitive option default back to true (from [9160]). Love your database columns, don't LOWER them. *Rick Olson*
974
975 * Add support for interleaving migrations by storing which migrations have run in the new schema_migrations table. Closes #11493 *Jordi Bunster*
976
977 * ActiveRecord::Base#sum defaults to 0 if no rows are returned. Closes #11550 *Kamal Fariz Mahyuddin*
978
979 * Ensure that respond_to? considers dynamic finder methods. Closes #11538. *James Mead*
980
981 * Ensure that save on parent object fails for invalid has_one association. Closes #10518. *Pratik Naik*
982
983 * Remove duplicate code from associations. *Pratik Naik*
984
985 * Refactor HasManyThroughAssociation to inherit from HasManyAssociation. Association callbacks and <association>_ids= now work with hm:t. #11516 *Ruy Asan*
986
987 * Ensure HABTM#create and HABTM#build do not load entire association. *Pratik Naik*
988
989 * Improve documentation. *Xavier Noria, Jack Danger Canty, leethal*
990
991 * Tweak ActiveRecord::Base#to_json to include a root value in the returned hash: {"post": {"title": ...}} *Rick Olson*
992
993 Post.find(1).to_json # => {"title": ...}
994 config.active_record.include_root_in_json = true
995 Post.find(1).to_json # => {"post": {"title": ...}}
996
997 * Add efficient #include? to AssociationCollection (for has_many/has_many :through/habtm). *stopdropandrew*
998
999 * PostgreSQL: create_ and drop_database support. #9042 *ez, pedz, Nick Sieger*
1000
1001 * Ensure that validates_uniqueness_of works with with_scope. Closes #9235. *Nik Wakelin, cavalle*
1002
1003 * Partial updates include only unsaved attributes. Off by default; set YourClass.partial_updates = true to enable. *Jeremy Kemper*
1004
1005 * Removing unnecessary uses_tzinfo helper from tests, given that TZInfo is now bundled *Geoff Buesing*
1006
1007 * Fixed that validates_size_of :within works in associations #11295, #10019 *cavalle*
1008
1009 * Track changes to unsaved attributes. *Jeremy Kemper*
1010
1011 * 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.

1327 * Added ActiveRecord::Base#to_json/from_json *David Heinemeier Hansson, Cheah Chu Yeow*
1328
1329 * Added ActiveRecord::Base#from_xml [David Heinemeier Hansson]. Example:

1333
1334 * Define dynamic finders as real methods after first usage. *bscofield*

1346 * Extract Firebird, FrontBase, and OpenBase adapters into gems. #9508, #9509, #9510 *Jeremy Kemper*
1347
1348 * RubyGem database adapters: expects a gem named activerecord-<database>-adapter with active_record/connection_adapters/<database>_adapter.rb in its load path. *Jeremy Kemper*

1371
1372 For more information see: http://dev.rubyonrails.org/ticket/8049
1373
1374 * Don't clobber includes passed to has_many.count *Jack Danger Canty*
1375
1376 * Make sure has_many uses :include when counting *Jack Danger Canty*
1377
1378 * Change the implementation of ActiveRecord's attribute reader and writer methods *Michael Koziarski*
1379 - Generate Reader and Writer methods which cache attribute values in hashes. This is to avoid repeatedly parsing the same date or integer columns.
1380 - Change exception raised when users use find with :select then try to access a skipped column. Plugins could override missing_attribute() to lazily load the columns.
1381 - Move method definition to the class, instead of the instance
1382 - Always generate the readers, writers and predicate methods.
1383
1384 * Perform a deep #dup on query cache results so that modifying activerecord attributes does not modify the cached attributes. *Rick Olson*

1389
1390 def using_open_id?
1391 !identity_url.blank?
1392 end
1393
1394 validates_presence_of :identity_url, :if => using_open_id?
1395 validates_presence_of :username, :unless => using_open_id?
1396 validates_presence_of :password, :unless => using_open_id?
1397
1398 * Fix #count on a has_many :through association so that it recognizes the :uniq option. Closes #8801 *Pratik Naik*
1399
1400 * Fix and properly document/test count(column_name) usage. Closes #8999 *Pratik Naik*
1401
1402 * Remove deprecated count(conditions=nil, joins=nil) usage. Closes #8993 *Pratik Naik*
1403
1404 * Change belongs_to so that the foreign_key assumption is taken from the association name, not the class name. Closes #8992 *Josh Susser*
1405
1406 OLD
1407 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is user_id
1408
1409 NEW
1410 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is visitor_id
1411

1443
1444 * Quickref for association methods. #7723 *marclove, Mindsweeper*
1445
1446 * Calculations: return nil average instead of 0 when there are no rows to average. #8298 *davidw*
1447
1448 * acts_as_nested_set: direct_children is sorted correctly. #4761 *Josh Peek, rails@33lc0.net*

1469
1470 * Optimistic locking: revert the lock version when an update fails. #7840 *plang*
1471
1472 * Migrations: add_column supports custom column types. #7742 *jsgarvin, Theory*
1473
1474 * 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*
1475
1476 * Ensure that associations with :dependent => :delete_all respect :conditions option. Closes #8034 *Jack Danger Canty, Josh Peek, Rick Olson*

1499
1500 * Provide brief introduction to what optimistic locking is. *fearoffish*
1501
1502 * Add documentation for :encoding option to mysql adapter. *marclove*
1503
1504 * Added short-hand declaration style to migrations (inspiration from Sexy Migrations, http://errtheblog.com/post/2381) [David Heinemeier Hansson]. Example:
1505
1506 create_table "products" do |t|
1507 t.column "shop_id", :integer
1508 t.column "creator_id", :integer
1509 t.column "name", :string, :default => "Untitled"
1510 t.column "value", :string, :default => "Untitled"
1511 t.column "created_at", :datetime
1512 t.column "updated_at", :datetime
1513 end
1514
1515 ...can now be written as:
1516
1517 create_table :products do |t|
1518 t.integer :shop_id, :creator_id
1519 t.string :name, :value, :default => "Untitled"
1520 t.timestamps
1521 end
1522
1523 * 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*
1524
1525 * Improve performance of calling .create on has_many :through associations. *evan*
1526
1527 * Improved cloning performance by relying less on exception raising #8159 *Blaine*

1530
1531 * Added yielding of Builder instance for ActiveRecord::Base#to_xml calls *David Heinemeier Hansson*
1532

1536
1537 * SQLite: binary escaping works with $KCODE='u'. #7862 *tsuka*
1538
1539 * Base#to_xml supports serialized attributes. #7502 *jonathan*
1540
1541 * Base.update_all :order and :limit options. Useful for MySQL updates that must be ordered to avoid violating unique constraints. *Jeremy Kemper*
1542
1543 * 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*
1544
1545 * 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*
1546
1547 * 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*
1548
1549 * 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*
1550
1551 * Allow a polymorphic :source for has_many :through associations. Closes #7143 *protocool*
1552
1553 * Consistent public/protected/private visibility for chained methods. #7813 *Dan Manges*
1554

1556
1557 * Consistently quote primary key column names. #7763 *toolmantim*
1558
1559 * Fixtures: fix YAML ordered map support. #2665 *Manuel Holtgrewe, nfbuckley*
1560
1561 * DateTimes assume the default timezone. #7764 *Geoff Buesing*
1562
1563 * Sybase: hide timestamp columns since they're inherently read-only. #7716 *Mike Joyce*
1564
1565 * Oracle: overflow Time to DateTime. #7718 *Michael Schoen*
1566
1567 * PostgreSQL: don't use async_exec and async_query with postgres-pr. #7727, #7762 *flowdelic, toolmantim*
1568
1569 * Fix has_many :through << with custom foreign keys. #6466, #7153 *naffis, Rich Collins*
1570
1571 * Test DateTime native type in migrations, including an edge case with dates
1572 during calendar reform. #7649, #7724 *fedot, Geoff Buesing*
1573
1574 * SQLServer: correctly schema-dump tables with no indexes or descending indexes. #7333, #7703 *Jakob Skjerning, Tom Ward*
1575
1576 * SQLServer: recognize real column type as Ruby float. #7057 *sethladd, Tom Ward*
1577
1578 * Added fixtures :all as a way of loading all fixtures in the fixture directory at once #7214 *Manfred Stienstra*
1579
1580 * Added database connection as a yield parameter to ActiveRecord::Base.transaction so you can manually rollback [David Heinemeier Hansson]. Example:
1581
1582 transaction do |transaction|
1583 david.withdrawal(100)
1584 mary.deposit(100)
1585 transaction.rollback! # rolls back the transaction that was otherwise going to be successful
1586 end
1587
1588 * Made increment_counter/decrement_counter play nicely with optimistic locking, and added a more general update_counters method *Jamis Buck*
1589
1590 * 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*
1591 Task.cache { Task.find(1); Task.find(1) } # => 1 query
1592
1593 * 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*
1594
1595 * Oracle: fix lob and text default handling. #7344 *gfriedrich, Michael Schoen*
1596
1597 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
1598
1599 * MySQL: blob and text columns may not have defaults in 5.x. Update fixtures schema for strict mode. #6695 *Dan Kubb*
1600
1601 * 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*
1602
1603 * MySQL: SET SQL_AUTO_IS_NULL=0 so 'where id is null' doesn't select the last inserted id. #6778 *Jonathan Viney, timc*
1604
1605 * Use Date#to_s(:db) for quoted dates. #7411 *Michael Schoen*
1606
1607 * Don't create instance writer methods for class attributes. Closes #7401 *Rick Olson*
1608
1609 * Docs: validations examples. #7343 *zackchandler*
1610
1611 * Add missing tests ensuring callbacks work with class inheritance. Closes #7339 *sandofsky*
1612
1613 * Fixtures use the table name and connection from set_fixture_class. #7330 *Anthony Eden*
1614
1615 * Remove useless code in #attribute_present? since 0 != blank?. Closes #7249 *Josh Susser*
1616
1617 * Fix minor doc typos. Closes #7157 *Josh Susser*
1618
1619 * Fix incorrect usage of #classify when creating the eager loading join statement. Closes #7044 *Josh Susser*

1624
1625 * Make sure sqlite3 driver closes open connections on disconnect *Rob Rasmussen*
1626
1627 * [DOC] clear up some ambiguity with the way has_and_belongs_to_many creates the default join table name. #7072 *Jeremy McAnally*
1628
1629 * change_column accepts :default => nil. Skip column options for primary keys. #6956, #7048 *Dan Manges, Jeremy Kemper*
1630
1631 * 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*
1632
1633 * Oracle: create_table takes a :sequence_name option to override the 'tablename_seq' default. #7000 *Michael Schoen*
1634
1635 * MySQL: retain SSL settings on reconnect. #6976 *randyv2*
1636
1637 * Apply scoping during initialize instead of create. Fixes setting of foreign key when using find_or_initialize_by with scoping. *Cody Fauser*
1638
1639 * SQLServer: handle [quoted] table names. #6635 *rrich*
1640
1641 * acts_as_nested_set works with single-table inheritance. #6030 *Josh Susser*
1642
1643 * PostgreSQL, Oracle: correctly perform eager finds with :limit and :order. #4668, #7021 *eventualbuddha, Michael Schoen*
1644
1645 * Pass a range in :conditions to use the SQL BETWEEN operator. #6974 *Dan Manges*
1646 Student.find(:all, :conditions => { :grade => 9..12 })
1647
1648 * Fix the Oracle adapter for serialized attributes stored in CLOBs. Closes #6825 *mschoen, tdfowler*
1649
1650 * [DOCS] Apply more documentation for ActiveRecord Reflection. Closes #4055 *Robby Russell*
1651
1652 * [DOCS] Document :allow_nil option of #validate_uniqueness_of. Closes #3143 *Caio Chassot*
1653
1654 * Bring the sybase adapter up to scratch for 1.2 release. *jsheets*
1655
1656 * Rollback new_record? and id when an exception is raised in a save callback. #6910 *Ben Curren, outerim*
1657
1658 * Pushing a record on an association collection doesn't unnecessarily load all the associated records. *Obie Fernandez, Jeremy Kemper*
1659
1660 * Oracle: fix connection reset failure. #6846 *leonlleslie*
1661
1662 * Subclass instantiation doesn't try to explicitly require the corresponding subclass. #6840 *leei, Jeremy Kemper*
1663
1664 * 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*
1665
1666 * 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*
1667
1668 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
1669
1670 * Add AssociationCollection#create! to be consistent with AssociationCollection#create when dealing with a foreign key that is a protected attribute *Cody Fauser*
1671
1672 * 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*
1673
1674 * Change fixture_path to a class inheritable accessor allowing test cases to have their own custom set of fixtures. #6672 *Zach Dennis*
1675
1676 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
1677
1678 * Simplify query_attribute by typecasting the attribute value and checking whether it's nil, false, zero or blank. #6659 *Jonathan Viney*
1679
1680 * 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*
1681
1682 * Run validations in the order they were declared. #6657 *obrie*
1683
1684 * 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*
1685
1686 * Simplify association proxy implementation by factoring construct_scope out of method_missing. #6643 *martin*
1687
1688 * Oracle: automatically detect the primary key. #6594 *vesaria, Michael Schoen*
1689
1690 * 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*
1691
1692 * Don't inspect unloaded associations. #2905 *lmarlow*

1705 find(:all, :conditions => { :topic_id => [1, 2, 3], :last_read => nil }
1706
1707 * 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*
1708
1709 * SQLite: fix calculations workaround, remove count(distinct) query rewrite, cleanup test connection scripts. *Jeremy Kemper*
1710

1718
1719 * 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*
1720
1721 * Make add_column use the options hash with the Sqlite Adapter. Closes #6464 *obrie*
1722
1723 * Document other options available to migration's add_column. #6419 *grg*
1724

1734
1735 * Add #delete support to has_many :through associations. Closes #6049 *Martin Landers*
1736
1737 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
1738
1739 * 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*
1740
1741 * 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*
1742
1743 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*
1744
1745 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
1746
1747 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
1748
1749 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
1750
1751 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
1752
1753 * 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*
1754
1755 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
1756
1757 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*
1758
1759 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*

1768
1769 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
1770
1771 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
1772
1773 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
1774
1775 * 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*
1776
1777 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
1778
1779 * Document validates_presences_of behavior with booleans: you probably want validates_inclusion_of :attr, :in => [true, false]. #2253 *Bob Silva*
1780
1781 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
1782
1783 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
1784
1785 * Deprecation: update docs. #5998 *Jakob Skjerning, Kevin Clark*
1786
1787 * Add some XmlSerialization tests for ActiveRecord *Rick Olson*
1788
1789 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
1790
1791 * Tighten rescue clauses. #5985 *james@grayproductions.net*
1792
1793 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
1794
1795 * 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*
1796
1797 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
1798

1810
1811 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
1812
1813 * 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*
1814
1815 * 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*
1816
1817 # Create a tagging to associate the post and tag.
1818 post.tags << Tag.find_by_name('old')
1819 post.tags.create! :name => 'general'
1820
1821 # Would have been:
1822 post.taggings.create!(:tag => Tag.find_by_name('finally')
1823 transaction do
1824 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
1825 end
1826

1832 Example: Invoice::Lineitem is given table name invoice_lineitems
1833
1834 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
1835 # people_active_last_name_index, people_active_deactivated_at_index
1836 add_index :people, [:active, :last_name]
1837 add_index :people, [:active, :deactivated_at]
1838 remove_index :people, [:active, :last_name]
1839 remove_index :people, [:active, :deactivated_at]
1840
1841 WARNING: backward-incompatibility. Multicolumn indexes created before this
1842 revision were named using the first column name only. Now they're uniquely
1843 named using all indexed columns.
1844
1845 To remove an old multicolumn index, remove_index :table_name, :first_column
1846
1847 * Fix for deep includes on the same association. *richcollins@gmail.com*
1848
1849 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
1850
1851 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
1852
1853 * Document find's :from option. Closes #5762. *andrew@redlinesoftware.com*
1854
1855 * 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*
1856
1857 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
1858
1859 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
1860
1861 * Add documentation for how to disable timestamps on a per model basis. Closes #5684. *matt@mattmargolis.net Marcel Molina Jr.*
1862
1863 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
1864
1865 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
1866
1867 * Formally deprecate the deprecated finders. *Michael Koziarski*

1880
1881 assert (Topic.exists?(:author_name => "David"))
1882 assert (Topic.exists?(:author_name => "Mary", :approved => true))
1883 assert (Topic.exists?(["parent_id = ?", 1]))
1884

1890
1891 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
1892
1893 * Allow #count through a has_many association to accept :include. *Dan Peterson*
1894

1902
1903 * Oracle: BigDecimal support. #5667 *Michael Schoen*

1905 * 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*
1906
1907 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*

1909 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
1910
1911 * Update callbacks documentation. #3970 *Robby Russell <robby@planetargon.com>*
1912
1913 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
1914
1915 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
1916
1917 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
1918
1919 * 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*
1920
1921 * 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*
1922
1923 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
1924
1925 * Minor tweak to improve performance of ActiveRecord::Base#to_param.
1926
1927 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
1928
1929 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
1930
1931 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
1932
1933 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
1934
1935 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
1936
1937 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
1938
1939 * 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*
1940 # Obtain an exclusive lock on person 1 so we can safely increment visits.
1941 Person.transaction do
1942 # select * from people where id=1 for update
1943 person = Person.find(1, :lock => true)
1944 person.visits += 1
1945 person.save!
1946 end
1947
1948 * 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*
1949
1950 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
1951
1952 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
1953
1954 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
1955
1956 * 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*
1957
1958 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
1959
1960 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
1961
1962 ...is the same as:
1963
1964 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
1965
1966 This makes it easier to pass in the options from a form or otherwise outside.
1967

1976
1977 * Fixed that count distinct should use the selected column even when using :include #5251 *anna@wota.jp*
1978
1979 * 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*
1980
1981 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
1982
1983 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
1984
1985 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
1986 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
1987 Foo.find(:first, :conditions => ['bar_id = ?', bar])
1988
1989 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
1990
1991 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
1992
1993 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*
1994

1996 Closes #4433 *Josh Susser*
1997

2011
2012 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2013
2014 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2015
2016 * 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*

2191
2192 * Make add_column use the options hash with the Sqlite Adapter. Closes #6464 *obrie*
2193
2194 * Document other options available to migration's add_column. #6419 *grg*
2195
2196 * MySQL: all_hashes compatibility with old MysqlRes class. #6429, #6601 *Jeremy Kemper*
2197
2198 * Fix has_many :through to add the appropriate conditions when going through an association using STI. Closes #5783. *Jonathan Viney*
2199

2201
2202 * Restore eager condition interpolation, document it's differences *Rick Olson*
2203
2204 * 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*
2205
2206 * Add #delete support to has_many :through associations. Closes #6049 *Martin Landers*
2207
2208 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
2209
2210 * 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*
2211
2212 * 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*
2213
2214 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*
2215
2216 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
2217
2218 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
2219
2220 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
2221
2222 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
2223
2224 * 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*
2225
2226 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
2227
2228 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*
2229
2230 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*
2231

2233
2234 * Add a :namespace option to AR::Base#to_xml *Michael Koziarski*
2235
2236 * Deprecation tests. Remove warnings for dynamic finders and for the foo_count method if it's also an attribute. *Jeremy Kemper*
2237
2238 * Mock Time.now for more accurate Touch mixin tests. #6213 *Dan Peterson*
2239
2240 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
2241
2242 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
2243
2244 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
2245
2246 * 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*
2247
2248 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
2249
2250 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
2251
2252 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
2253
2254 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
2255
2256 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
2257
2258 * 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*
2259
2260 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
2261
2262 * 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*
2263
2264 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
2265
2266 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
2267
2268 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*
2269
2270 * MySQL: update test schema for MySQL 5 strict mode. #5861 *Tom Ward*
2271
2272 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2273
2274 * 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*
2275
2276 * 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*
2277
2278 # Create a tagging to associate the post and tag.
2279 post.tags << Tag.find_by_name('old')
2280 post.tags.create! :name => 'general'
2281
2282 # Would have been:
2283 post.taggings.create!(:tag => Tag.find_by_name('finally')
2284 transaction do
2285 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
2286 end
2287
2288 * Cache nil results for :included has_one associations also. #5787 *Michael Schoen*
2289
2290 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
2291
2292 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
2293 Example: Invoice::Lineitem is given table name invoice_lineitems
2294
2295 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2296 # people_active_last_name_index, people_active_deactivated_at_index
2297 add_index :people, [:active, :last_name]
2298 add_index :people, [:active, :deactivated_at]
2299 remove_index :people, [:active, :last_name]
2300 remove_index :people, [:active, :deactivated_at]
2301
2302 WARNING: backward-incompatibility. Multicolumn indexes created before this
2303 revision were named using the first column name only. Now they're uniquely
2304 named using all indexed columns.
2305
2306 To remove an old multicolumn index, remove_index :table_name, :first_column
2307
2308 * Fix for deep includes on the same association. *richcollins@gmail.com*
2309
2310 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
2311
2312 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
2313
2314 * 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*
2315
2316 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
2317
2318 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
2319
2320 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
2321
2322 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
2323
2324 * Formally deprecate the deprecated finders. *Michael Koziarski*
2325
2326 * Formally deprecate rich associations. *Michael Koziarski*
2327
2328 * Fixed that default timezones for new / initialize should uphold utc setting #5709 *daniluk@yahoo.com*
2329
2330 * Fix announcement of very long migration names. #5722 *blake@near-time.com*
2331

2333
2334 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
2335

2337
2338 assert (Topic.exists?(:author_name => "David"))

2340 assert (Topic.exists?(["parent_id = ?", 1]))
2341

2345
2346 * Factor the attribute#{suffix} methods out of method_missing for easier extension. *Jeremy Kemper*
2347
2348 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
2349
2350 * Allow #count through a has_many association to accept :include. *Dan Peterson*
2351
2352 * create_table rdoc: suggest :id => false for habtm join tables. *Zed Shaw*
2353
2354 * PostgreSQL: return array fields as strings. #4664 *Robby Russell*
2355
2356 * 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*
2357
2358 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2359
2360 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2361
2362 * 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*
2363
2364 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*
2365
2366 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2367
2368 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2369
2370 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2371
2372 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2373
2374 * 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*
2375
2376 * 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*
2377
2378 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2379
2380 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2381
2382 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2383
2384 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2385
2386 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2387
2388 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2389
2390 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2391
2392 * 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*
2393 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2394 Person.transaction do
2395 # select * from people where id=1 for update
2396 person = Person.find(1, :lock => true)
2397 person.visits += 1
2398 person.save!
2399 end
2400
2401 * 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*
2402
2403 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2404
2405 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2406
2407 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2408
2409 * 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*
2410
2411 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2412
2413 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2414
2415 ...is the same as:
2416
2417 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2418
2419 This makes it easier to pass in the options from a form or otherwise outside.
2420
2421
2422 * Fixed issues with BLOB limits, charsets, and booleans for Firebird #5194, #5191, #5189 *kennethkunz@gmail.com*

2429
2430 * Fixed that count distinct should use the selected column even when using :include #5251 *anna@wota.jp*
2431
2432 * 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*
2433
2434 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
2435
2436 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
2437
2438 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
2439 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
2440 Foo.find(:first, :conditions => ['bar_id = ?', bar])
2441
2442 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
2443
2444 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
2445
2446 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*
2447
2448 * Provide Association Extensions access to the instance that the association is being accessed from.
2449 Closes #4433 *Josh Susser*
2450
2451 * Update OpenBase adaterp's maintainer's email address. Closes #5176. *Derrick Spell*
2452
2453 * Add a quick note about :select and eagerly included associations. *Rick Olson*
2454
2455 * Add docs for the :as option in has_one associations. Closes #5144 *cdcarter@gmail.com*
2456
2457 * Fixed that has_many collections shouldn't load the entire association to do build or create *David Heinemeier Hansson*
2458
2459 * Added :allow_nil option for aggregations #5091 *Ian White*
2460
2461 * Fix Oracle boolean support and tests. Closes #5139. *Michael Schoen*
2462
2463 * 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*
2464
2465 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2466
2467 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2468
2469 * 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*
2470
2471 * Dates and times interpret empty strings as nil rather than 2000-01-01. #4830 *kajism@yahoo.com*
