119 ## Rails 3.1.1 (October 7, 2011) ##
120
121 * Raise an exception if the primary key of a model in an association is needed
122 but unknown. Fixes #3207.
123
124 *Jon Leighton*
125
126 * Add deprecation for the preload_associations method. Fixes #3022.
127
128 *Jon Leighton*
129
130 * Don't require a DB connection when loading a model that uses set_primary_key. GH #2807.
131
132 *Jon Leighton*
133
134 * Fix using select() with a habtm association, e.g. Person.friends.select(:name). GH #3030 and
135 \#2923.
136
137 *Hendy Tanata*
138
139 * Fix belongs_to polymorphic with custom primary key on target. GH #3104.
140
141 *Jon Leighton*
142
143 * CollectionProxy#replace should change the DB records rather than just mutating the array.
144 Fixes #3020.
145
146 *Jon Leighton*
147
148 * LRU cache in mysql and sqlite are now per-process caches.
149
150 * lib/active_record/connection_adapters/mysql_adapter.rb: LRU cache
151 keys are per process id.
152 * lib/active_record/connection_adapters/sqlite_adapter.rb: ditto
153
154 *Aaron Patterson*
155
156 * Database adapters use a statement pool for limiting the number of open
157 prepared statments on the database. The limit defaults to 1000, but can
158 be adjusted in your database config by changing 'statement_limit'.
159
160 * Fix clash between using 'preload', 'joins' or 'eager_load' in a default scope and including the
161 default scoped model in a nested through association. (GH #2834.) *Jon Leighton*
162
163 * Ensure we are not comparing a string with a symbol in HasManyAssociation#inverse_updates_counter_cache?.
164 Fixes GH #2755, where a counter cache could be decremented twice as far as it was supposed to be.
165
166 *Jon Leighton*
167
168 * Don't send any queries to the database when the foreign key of a belongs_to is nil. Fixes
169 GH #2828. *Georg Friedrich*
170
171 * Fixed find_in_batches method to not include order from default_scope. See GH #2832 *Arun Agrawal*
172
173 * Don't compute table name for abstract classes. Fixes problem with setting the primary key
174 in an abstract class. See GH #2791. *Akira Matsuda*
175
176 * Psych errors with poor yaml formatting are proxied. Fixes GH #2645 and
177 GH #2731
178
179 * Use the LIMIT word with the methods #last and #first. Fixes GH #2783 *Damien Mathieu*
180
181 ## Rails 3.1.0 (August 30, 2011) ##
182
183 * Add a proxy_association method to association proxies, which can be called by association
184 extensions to access information about the association. This replaces proxy_owner etc with
185 proxy_association.owner.
186
187 *Jon Leighton*
188
189 * 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*
190
191 * Deprecated the AssociationCollection constant. CollectionProxy is now the appropriate constant
192 to use, though be warned that this is not really a public API.
193
194 This should solve upgrade problems with the will_paginate plugin (and perhaps others). Thanks
195 Paul Battley for reporting.
196
197 *Jon Leighton*
198
199 * ActiveRecord::MacroReflection::AssociationReflection#build_record has a new method signature.
200
201 Before: def build_association(*options)
202 After: def build_association(*options, &block)
203
204 Users who are redefining this method to extend functionality should ensure that the block is
205 passed through to ActiveRecord::Base#new.
206
207 This change is necessary to fix https://github.com/rails/rails/issues/1842.
208
209 A deprecation warning and workaround has been added to 3.1, but authors will need to update
210 their code for it to work correctly in 3.2.
211
212 *Jon Leighton*
213
214 * AR#pluralize_table_names can be used to singularize/pluralize table name of an individual model:
215
216 class User < ActiveRecord::Base
217 self.pluralize_table_names = false
218 end
219
220 Previously this could only be set globally for all models through ActiveRecord::Base.pluralize_table_names. *Guillermo Iguaran*
221
222 * Add block setting of attributes to singular associations:
223
224 class User < ActiveRecord::Base
225 has_one :account
226 end
227
228 user.build_account{ |a| a.credit_limit => 100.0 }
229
230 The block is called after the instance has been initialized. *Andrew White*
231
232 * 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*
233
234 * CSV Fixtures are deprecated and support will be removed in Rails 3.2.0
235
236 * AR#new, AR#create, AR#create!, AR#update_attributes and AR#update_attributes! all accept a second hash as option that allows you
237 to specify which role to consider when assigning attributes. This is built on top of ActiveModel's
238 new mass assignment capabilities:
239
240 class Post < ActiveRecord::Base
241 attr_accessible :title
242 attr_accessible :title, :published_at, :as => :admin
243 end
244
245 Post.new(params[:post], :as => :admin)
246
247 assign_attributes() with similar API was also added and attributes=(params, guard) was deprecated.
248
249 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.
250
251 *Josh Kalderimis*
252
253 * default_scope can take a block, lambda, or any other object which responds to `call` for lazy
254 evaluation:
255
256 default_scope { ... }
257 default_scope lambda { ... }
258 default_scope method(:foo)
259
260 This feature was originally implemented by Tim Morgan, but was then removed in favour of
261 defining a 'default_scope' class method, but has now been added back in by Jon Leighton.
262 The relevant lighthouse ticket is #1812.
263
264 * Default scopes are now evaluated at the latest possible moment, to avoid problems where
265 scopes would be created which would implicitly contain the default scope, which would then
266 be impossible to get rid of via Model.unscoped.
267
268 Note that this means that if you are inspecting the internal structure of an
269 ActiveRecord::Relation, it will *not* contain the default scope, though the resulting
270 query will do. You can get a relation containing the default scope by calling
271 ActiveRecord#with_default_scope, though this is not part of the public API.
272
273 *Jon Leighton*
274
275 * If you wish to merge default scopes in special ways, it is recommended to define your default
276 scope as a class method and use the standard techniques for sharing code (inheritance, mixins,
277 etc.):
278
279 class Post < ActiveRecord::Base
280 def self.default_scope
281 where(:published => true).where(:hidden => false)
282 end
283 end
284
285 *Jon Leighton*
286
287 * PostgreSQL adapter only supports PostgreSQL version 8.2 and higher.
288
289 * ConnectionManagement middleware is changed to clean up the connection pool
290 after the rack body has been flushed.
291
292 * Added an update_column method on ActiveRecord. This new method updates a given attribute on an object, skipping validations and callbacks.
293 It is recommended to use #update_attribute unless you are sure you do not want to execute any callback, including the modification of
294 the updated_at column. It should not be called on new records.
295 Example:
296
297 User.first.update_column(:name, "sebastian") # => true
298
299 *Sebastian Martinez*
300
301 * Associations with a :through option can now use *any* association as the
302 through or source association, including other associations which have a
303 :through option and has_and_belongs_to_many associations
304
305 *Jon Leighton*
306
307 * The configuration for the current database connection is now accessible via
308 ActiveRecord::Base.connection_config. *fxn*
309
310 * limits and offsets are removed from COUNT queries unless both are supplied.
311 For example:
312
313 People.limit(1).count # => 'SELECT COUNT(*) FROM people'
314 People.offset(1).count # => 'SELECT COUNT(*) FROM people'
315 People.limit(1).offset(1).count # => 'SELECT COUNT(*) FROM people LIMIT 1 OFFSET 1'
316
317 *lighthouse #6262*
318
319 * ActiveRecord::Associations::AssociationProxy has been split. There is now an Association class
320 (and subclasses) which are responsible for operating on associations, and then a separate,
321 thin wrapper called CollectionProxy, which proxies collection associations.
322
323 This prevents namespace pollution, separates concerns, and will allow further refactorings.
324
325 Singular associations (has_one, belongs_to) no longer have a proxy at all. They simply return
326 the associated record or nil. This means that you should not use undocumented methods such
327 as bob.mother.create - use bob.create_mother instead.
328
329 *Jon Leighton*
330
331 * Make has_many :through associations work correctly when you build a record and then save it. This
332 requires you to set the :inverse_of option on the source reflection on the join model, like so:
333
334 class Post < ActiveRecord::Base
335 has_many :taggings
336 has_many :tags, :through => :taggings
337 end
338
339 class Tagging < ActiveRecord::Base
340 belongs_to :post
341 belongs_to :tag, :inverse_of => :tagging # :inverse_of must be set!
342 end
343
344 class Tag < ActiveRecord::Base
345 has_many :taggings
346 has_many :posts, :through => :taggings
347 end
348
349 post = Post.first
350 tag = post.tags.build :name => "ruby"
351 tag.save # will save a Taggable linking to the post
352
353 *Jon Leighton*
354
355 * Support the :dependent option on has_many :through associations. For historical and practical
356 reasons, :delete_all is the default deletion strategy employed by association.delete(*records),
357 despite the fact that the default strategy is :nullify for regular has_many. Also, this only
358 works at all if the source reflection is a belongs_to. For other situations, you should directly
359 modify the through association.
360
361 *Jon Leighton*
362
363 * Changed the behaviour of association.destroy for has_and_belongs_to_many and has_many :through.
364 From now on, 'destroy' or 'delete' on an association will be taken to mean 'get rid of the link',
365 not (necessarily) 'get rid of the associated records'.
366
367 Previously, has_and_belongs_to_many.destroy(*records) would destroy the records themselves. It
368 would not delete any records in the join table. Now, it deletes the records in the join table.
369
370 Previously, has_many_through.destroy(*records) would destroy the records themselves, and the
371 records in the join table. [Note: This has not always been the case; previous version of Rails
372 only deleted the records themselves.] Now, it destroys only the records in the join table.
373
374 Note that this change is backwards-incompatible to an extent, but there is unfortunately no
375 way to 'deprecate' it before changing it. The change is being made in order to have
376 consistency as to the meaning of 'destroy' or 'delete' across the different types of associations.
377
378 If you wish to destroy the records themselves, you can do records.association.each(&:destroy)
379
380 *Jon Leighton*
381
382 * 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*
383
384 Example:
385
386 change_table(:users, :bulk => true) do |t|
387 t.string :company_name
388 t.change :birthdate, :datetime
389 end
390
391 This will now result in:
392
393 ALTER TABLE `users` ADD COLUMN `company_name` varchar(255), CHANGE `updated_at` `updated_at` datetime DEFAULT NULL
394
395 * Removed support for accessing attributes on a has_and_belongs_to_many join table. This has been
396 documented as deprecated behaviour since April 2006. Please use has_many :through instead.
397 *Jon Leighton*
398
399 * Added a create_association! method for has_one and belongs_to associations. *Jon Leighton*
400
401 * Migration files generated from model and constructive migration generators
402 (for example, add_name_to_users) use the reversible migration's `change`
403 method instead of the ordinary `up` and `down` methods. *Prem Sichanugrist*
404
405 * Removed support for interpolating string SQL conditions on associations. Instead, you should
406 use a proc, like so:
407
408 Before:
409
410 has_many :things, :conditions => 'foo = #{bar}'
411
412 After:
413
414 has_many :things, :conditions => proc { "foo = #{bar}" }
415
416 Inside the proc, 'self' is the object which is the owner of the association, unless you are
417 eager loading the association, in which case 'self' is the class which the association is within.
418
419 You can have any "normal" conditions inside the proc, so the following will work too:
420
421 has_many :things, :conditions => proc { ["foo = ?", bar] }
422
423 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
424 'record' to get the record being inserted or deleted. This is now passed as an argument to
425 the proc.
426
427 * Added ActiveRecord::Base#has_secure_password (via ActiveModel::SecurePassword) to encapsulate dead-simple password usage with BCrypt encryption and salting [DHH]. Example:
428
429 # Schema: User(name:string, password_digest:string, password_salt:string)
430 class User < ActiveRecord::Base
431 has_secure_password
432 end
433
434 user = User.new(:name => "david", :password => "", :password_confirmation => "nomatch")
435 user.save # => false, password required
436 user.password = "mUc3m00RsqyRe"
437 user.save # => false, confirmation doesn't match
438 user.password_confirmation = "mUc3m00RsqyRe"
439 user.save # => true
440 user.authenticate("notright") # => false
441 user.authenticate("mUc3m00RsqyRe") # => user
442 User.find_by_name("david").try(:authenticate, "notright") # => nil
443 User.find_by_name("david").try(:authenticate, "mUc3m00RsqyRe") # => user
444
445
446 * When a model is generated add_index is added by default for belongs_to or references columns
447
448 rails g model post user:belongs_to will generate the following:
449
450 class CreatePosts < ActiveRecord::Migration
451 def change
452 create_table :posts do |t|
453 t.belongs_to :user
454 t.timestamps
455 end
456 add_index :posts, :user_id
457 end
458 end
459
460 *Santiago Pastorino*
461
462 * Setting the id of a belongs_to object will update the reference to the
463 object. *#2989 state:resolved*
464
465 * ActiveRecord::Base#dup and ActiveRecord::Base#clone semantics have changed
466 to closer match normal Ruby dup and clone semantics.
467
468 * Calling ActiveRecord::Base#clone will result in a shallow copy of the record,
469 including copying the frozen state. No callbacks will be called.
470
471 * Calling ActiveRecord::Base#dup will duplicate the record, including calling
472 after initialize hooks. Frozen state will not be copied, and all associations
473 will be cleared. A duped record will return true for new_record?, have a nil
474 id field, and is saveable.
475
476 * Migrations can be defined as reversible, meaning that the migration system
477 will figure out how to reverse your migration. To use reversible migrations,
478 just define the "change" method. For example:
479
480 class MyMigration < ActiveRecord::Migration
481 def change
482 create_table(:horses) do
483 t.column :content, :text
484 t.column :remind_at, :datetime
485 end
486 end
487 end
488
489 Some things cannot be automatically reversed for you. If you know how to
490 reverse those things, you should define 'up' and 'down' in your migration. If
491 you define something in `change` that cannot be reversed, an
492 IrreversibleMigration exception will be raised when going down.
493
494 * Migrations should use instance methods rather than class methods:
495 class FooMigration < ActiveRecord::Migration
496 def up
497 ...
498 end
499 end
500
501 *Aaron Patterson*
502
503 * has_one maintains the association with separate after_create/after_update instead
504 of a single after_save. *fxn*
505
506 * The following code:
507
508 Model.limit(10).scoping { Model.count }
509
510 now generates the following SQL:
511
512 SELECT COUNT(*) FROM models LIMIT 10
513
514 This may not return what you want. Instead, you may with to do something
515 like this:
516
517 Model.limit(10).scoping { Model.all.size }
518

522 ## Rails 3.0.7 (April 18, 2011) ##
523
524 * Destroying records via nested attributes works independent of reject_if LH #6006 *Durran Jordan*
525
526 * Delegate any? and many? to Model.scoped for consistency *Andrew White*
527
528 * Quote the ORDER BY clause in batched finds - fixes #6620 *Andrew White*
529
530 * Change exists? so records are not instantiated - fixes #6127. This prevents after_find
531 and after_initialize callbacks being triggered when checking for record existence.
532 *Andrew White*
533
534 * Fix performance bug with attribute accessors which only occurred on Ruby 1.8.7, and ensure we
535 cache type-casted values when the column returned from the db contains non-standard chars.
536 *Jon Leighton*
537
538 * Fix a performance regression introduced here 86acbf1cc050c8fa8c74a10c735e467fb6fd7df8
539 related to read_attribute method *Stian Grytøyr*
540
541
542 ## Rails 3.0.6 (April 5, 2011) ##
543
544 * Un-deprecate reorder method *Sebastian Martinez*
545
546 * Extensions are applied when calling +except+ or +only+ on relations.
547 Thanks to Iain Hecker.
548
549 * Schemas set in set_table_name are respected by the mysql adapter. LH #5322
550
551 * Fixed a bug when empty? was called on a grouped Relation that wasn't loaded.
552 LH #5829
553
554 * Reapply extensions when using except and only. Thanks Iain Hecker.
555
556 * Binary data is escaped when being inserted to SQLite3 Databases. Thanks
557 Naruse!
558
559
560 ## Rails 3.0.5 (February 26, 2011) ##
561
562 * Model.where(:column => 1).where(:column => 2) will always produce an AND
563 query.
564
565 *Aaron Patterson*
566
567 * Deprecated support for interpolated association conditions in the form of :conditions => 'foo = #{bar}'.
568
569 Instead, you should use a proc, like so:
570
571 Before:
572
573 has_many :things, :conditions => 'foo = #{bar}'
574
575 After:
576
577 has_many :things, :conditions => proc { "foo = #{bar}" }
578
579 Inside the proc, 'self' is the object which is the owner of the association, unless you are
580 eager loading the association, in which case 'self' is the class which the association is within.
581
582 You can have any "normal" conditions inside the proc, so the following will work too:
583
584 has_many :things, :conditions => proc { ["foo = ?", bar] }
585
586 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
587 'record' to get the record being inserted or deleted. This is now passed as an argument to
588 the proc.
589
590 *Jon Leighton*
591
592
593 ## Rails 3.0.4 (February 8, 2011) ##
594
595 * Added deprecation warning for has_and_belongs_to_many associations where the join table has
596 additional attributes other than the keys. Access to these attributes is removed in 3.1.
597 Please use has_many :through instead. *Jon Leighton*
598
599
600 ## Rails 3.0.3 (November 16, 2010) ##
601
602 * Support find by class like this: Post.where(:name => Post)
603
604
605 ## Rails 3.0.2 (November 15, 2010) ##
606
607 * Dramatic speed increase (see: http://engineering.attinteractive.com/2010/10/arel-two-point-ohhhhh-yaaaaaa/) *Aaron Patterson*
608
609 * reorder is deprecated in favor of except(:order).order(...) *Santiago Pastorino*
610
611 * except is now AR public API
612
613 Model.order('name').except(:order).order('salary')
614
615 generates:
616
617 SELECT * FROM models ORDER BY salary
618
619 *Santiago Pastorino*
620
621 * The following code:
622
623 Model.limit(10).scoping { Model.count }
624
625 now generates the following SQL:
626
627 SELECT COUNT(*) FROM models LIMIT 10
628
629 This may not return what you want. Instead, you may with to do something
630 like this:
631
632 Model.limit(10).scoping { Model.all.size }
633
634 *Aaron Patterson*
635
636
637 ## Rails 3.0.1 (October 15, 2010) ##
638
639 * Introduce a fix for CVE-2010-3993
640
641
642 ## Rails 3.0.0 (August 29, 2010) ##
643
644 * Add scoping and unscoped as the syntax to replace the old with_scope and with_exclusive_scope *José Valim*
645
646 * New rake task, db:migrate:status, displays status of migrations #4947 *Kevin Skoglund*
647
648 * select and order for ActiveRecord now always concatenate nested calls. Use reorder if you want the original order to be overwritten *Santiago Pastorino*
649
650 * PostgreSQL: ensure the database time zone matches Ruby's time zone #4895 *Aaron Patterson*
651
652 * Fixed that ActiveRecord::Base.compute_type would swallow NoMethodError #4751 *Andrew Bloomgarden, Andrew White*
653
654 * Add index length support for MySQL. #1852 *Emili Parreno, Pratik Naik*
655
656 Example:
657
658 add_index(:accounts, :name, :name => 'by_name', :length => 10)
659 => CREATE INDEX by_name ON accounts(name(10))
660
661 add_index(:accounts, [:name, :surname], :name => 'by_name_surname', :length => {:name => 10, :surname => 15})
662 => CREATE INDEX by_name_surname ON accounts(name(10), surname(15))
663
664 * find_or_create_by_attr(value, ...) works when attr is protected. #4457 *Santiago Pastorino, Marc-André Lafortune*
665
666 * New callbacks: after_commit and after_rollback. Do expensive operations like image thumbnailing after_commit instead of after_save. #2991 *Brian Durand*
667
668 * 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*
669
670 * 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*
671
672 * PostgreSQL: drop support for old postgres driver. Use pg 0.9.0 or later. *Jeremy Kemper*
673
674 * Observers can prevent records from saving by returning false, just like before_save and friends. #4087 *Mislav Marohnić*
675
676 * Add Relation extensions. *Pratik Naik*
677
678 users = User.where(:admin => true).extending(User::AdminPowers)
679
680 latest_users = User.order('created_at DESC') do
681 def posts_count
682 Post.count(:user_id => to_a.map(&:id))
683 end
684 end
685
686 * To prefix the table names of all models in a module, define self.table_name_prefix on the module. #4032 *Andrew White*
687
688 * 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*
689
690 * 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*
691
692 * Allow relations to be used as scope.
693
694 class Item
695 scope :red, where(:colour => 'red')
696 end
697
698 Item.red.limit(10) # Ten red items
699
700 * Rename named_scope to scope. *Pratik Naik*
701
702 * Changed ActiveRecord::Base.store_full_sti_class to be true by default reflecting the previously announced Rails 3 default *DHH*
703
704 * Add Relation#except. *Pratik Naik*
705
706 one_red_item = Item.where(:colour => 'red').limit(1)
707 all_items = one_red_item.except(:where, :limit)
708
709 * Add Relation#delete_all. *Pratik Naik*
710
711 Item.where(:colour => 'red').delete_all
712
713 * Add Model.having and Relation#having. *Pratik Naik*
714
715 Developer.group("salary").having("sum(salary) > 10000").select("salary")
716
717 * Add Relation#count. *Pratik Naik*
718
719 legends = People.where("age > 100")
720 legends.count
721 legends.count(:age, :distinct => true)
722 legends.select('id').count
723
724 * Add Model.readonly and association_collection#readonly finder method. *Pratik Naik*
725
726 Post.readonly.to_a # Load all posts in readonly mode
727 @user.items.readonly(false).to_a # Load all the user items in writable mode
728
729 * Add .lock finder method *Pratik Naik*
730
731 User.lock.where(:name => 'lifo').to_a
732
733 old_items = Item.where("age > 100")
734 old_items.lock.each {|i| .. }
735
736 * Add Model.from and association_collection#from finder methods *Pratik Naik*
737
738 user = User.scoped
739 user.select('*').from('users, items')
740
741 * Add relation.destroy_all *Pratik Naik*
742
743 old_items = Item.where("age > 100")
744 old_items.destroy_all
745
746 * Add relation.exists? *Pratik Naik*
747
748 red_items = Item.where(:colours => 'red')
749 red_items.exists?
750 red_items.exists?(1)
751
752 * Add find(ids) to relations. *Pratik Naik*
753
754 old_users = User.order("age DESC")
755 old_users.find(1)
756 old_users.find(1, 2, 3)
757
758 * Add new finder methods to association collection. *Pratik Naik*
759
760 class User < ActiveRecord::Base
761 has_many :items
762 end
763
764 user = User.first
765 user.items.where(:items => {:colour => 'red'})
766 user.items.select('items.id')
767
768 * Add relation.reload to force reloading the records. *Pratik Naik*
769
770 topics = Topic.scoped
771 topics.to_a # force load
772 topics.first # returns a cached record
773 topics.reload
774 topics.first # Fetches a new record from the database
775
776 * Rename Model.conditions and relation.conditions to .where. *Pratik Naik*
777
778 Before :
779 User.conditions(:name => 'lifo')
780 User.select('id').conditions(["age > ?", 21])
781
782 Now :
783 User.where(:name => 'lifo')
784 User.select('id').where(["age > ?", 21])
785
786 * Add Model.select/group/order/limit/joins/conditions/preload/eager_load class methods returning a lazy relation. *Pratik Naik*
787
788 Examples :
789
790 posts = Post.select('id).order('name') # Returns a lazy relation
791 posts.each {|p| puts p.id } # Fires "select id from posts order by name"
792
793 * Model.scoped now returns a relation if invoked without any arguments. *Pratik Naik*
794
795 Example :
796
797 posts = Post.scoped
798 posts.size # Fires "select count(*) from posts" and returns the count
799 posts.each {|p| puts p.name } # Fires "select * from posts" and loads post objects
800
801 * Association inverses for belongs_to, has_one, and has_many. Optimization to reduce database queries. #3533 *Murray Steele*
802
803 # post.comments sets each comment's post without needing to :include
804 class Post < ActiveRecord::Base
805 has_many :comments, :inverse_of => :post
806 end
807
808 * MySQL: add_ and change_column support positioning. #3286 *Ben Marini*
809
810 * Reset your Active Record counter caches with the reset_counter_cache class method. #1211 *Mike Breen, Gabe da Silveira*
811
812 * Remove support for SQLite 2. Please upgrade to SQLite 3+ or install the plugin from git://github.com/rails/sqlite2_adapter.git *Pratik Naik*
813
814 * PostgreSQL: XML datatype support. #1874 *Leonardo Borges*
815
816 * 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*
817
818 * SQLite: drop support for 'dbfile' option in favor of 'database.' #2363 *Paul Hinze, Jeremy Kemper*
819
820 * Added :primary_key option to belongs_to associations. #765 *Szymon Nowak, Philip Hallstrom, Noel Rocha*
821 # employees.company_name references companies.name
822 Employee.belongs_to :company, :primary_key => 'name', :foreign_key => 'company_name'
823
824 * Implement #many? for NamedScope and AssociationCollection using #size. #1500 *Chris Kampmeier*
825
826 * Added :touch option to belongs_to associations that will touch the parent record when the current record is saved or destroyed *DHH*
827
828 * Added ActiveRecord::Base#touch to update the updated_at/on attributes (or another specified timestamp) with the current time *DHH*
829

840 has_one :author
841 has_many :pages
842
843 accepts_nested_attributes_for :author, :pages
844 end
845
846 * Make after_save callbacks fire only if the record was successfully saved. #1735 *Michael Lovitt*
847
848 Previously the callbacks would fire if a before_save cancelled saving.
849
850 * Support nested transactions using database savepoints. #383 *Jonathan Viney, Hongli Lai*
851
852 * Added dynamic scopes ala dynamic finders #1648 *Yaroslav Markin*
853
854 * Fixed that ActiveRecord::Base#new_record? should return false (not nil) for existing records #1219 *Yaroslav Markin*
855
856 * I18n the word separator for error messages. Introduces the activerecord.errors.format.separator translation key. #1294 *Akira Matsuda*
857
858 * Add :having as a key to find and the relevant associations. *Emilio Tagua*
859
860 * Added default_scope to Base #1381 [Paweł Kondzior]. Example:
861
862 class Person < ActiveRecord::Base
863 default_scope :order => 'last_name, first_name'
864 end
865
866 class Company < ActiveRecord::Base
867 has_many :people
868 end
869
870 Person.all # => Person.find(:all, :order => 'last_name, first_name')
871 Company.find(1).people # => Person.find(:all, :order => 'last_name, first_name', :conditions => { :company_id => 1 })
872
873
874 ## 2.2.1 RC2 (November 14th, 2008) ##
875
876 * Ensure indices don't flip order in schema.rb #1266 *Jordi Bunster*

882
883 * Skip collection ids reader optimization if using :finder_sql *Jeremy Kemper*
884
885 * Add Model#delete instance method, similar to Model.delete class method. #1086 *Hongli Lai (Phusion)*
886
887 * MySQL: cope with quirky default values for not-null text columns. #1043 *Frederick Cheung*
888
889 * Multiparameter attributes skip time zone conversion for time-only columns [#1030 state:resolved] *Geoff Buesing*
890
891 * Base.skip_time_zone_conversion_for_attributes uses class_inheritable_accessor, so that subclasses don't overwrite Base [#346 state:resolved] *Emilio Tagua*
892
893 * Added find_last_by dynamic finder #762 *Emilio Tagua*
894
895 * Internal API: configurable association options and build_association method for reflections so plugins may extend and override. #985 *Hongli Lai (Phusion)*
896
897 * Changed benchmarks to be reported in milliseconds *David Heinemeier Hansson*
898
899 * Connection pooling. #936 *Nick Sieger*
900
901 * Merge scoped :joins together instead of overwriting them. May expose scoping bugs in your code! #501 *Andrew White*
902
903 * 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*
904
905 * Transactional migrations for databases which support them. #834 *divoxx, Adam Wiggins, Tarmo Tänav*
906
907 * Set config.active_record.timestamped_migrations = false to have migrations with numeric prefix instead of UTC timestamp. #446. *Andrew Stone, Nik Wakelin*
908
909 * change_column_default preserves the not-null constraint. #617 *Tarmo Tänav*
910
911 * Fixed that create database statements would always include "DEFAULT NULL" (Nick Sieger) *#334*
912
913 * Add :tokenizer option to validates_length_of to specify how to split up the attribute string. #507. [David Lowenfels] Example :
914
915 \# Ensure essay contains at least 100 words.
916 validates_length_of :essay, :minimum => 100, :too_short => "Your essay must be at least %d words."), :tokenizer => lambda {|str| str.scan(/\w+/) }
917
918 * Allow conditions on multiple tables to be specified using hash. [Pratik Naik]. Example:
919
920 User.all :joins => :items, :conditions => { :age => 10, :items => { :color => 'black' } }
921 Item.first :conditions => { :items => { :color => 'red' } }
922
923 * Always treat integer :limit as byte length. #420 *Tarmo Tänav*
924
925 * Partial updates don't update lock_version if nothing changed. #426 *Daniel Morrison*
926
927 * Fix column collision with named_scope and :joins. #46 *Duncan Beevers, Mark Catley*
928
929 * db:migrate:down and :up update schema_migrations. #369 *Michael Raidel, RaceCondition*
930
931 * PostgreSQL: support :conditions => [':foo::integer', { :foo => 1 }] without treating the ::integer typecast as a bind variable. *Tarmo Tänav*
932
933 * MySQL: rename_column preserves column defaults. #466 *Diego Algorta*
934
935 * Add :from option to calculations. #397 *Ben Munat*
936
937 * Add :validate option to associations to enable/disable the automatic validation of associated models. Resolves #301. *Jan De Poorter*
938
939 * PostgreSQL: use 'INSERT ... RETURNING id' for 8.2 and later. *Jeremy Kemper*
940
941 * Added SQL escaping for :limit and :offset in MySQL *Jonathan Wiess*
942
943
944 ## 2.1.0 (May 31st, 2008) ##
945
946 * Add ActiveRecord::Base.sti_name that checks ActiveRecord::Base#store_full_sti_class? and returns either the full or demodulized name. *Rick Olson*
947
948 * Add first/last methods to associations/named_scope. Resolved #226. *Ryan Bates*
949
950 * Added SQL escaping for :limit and :offset #288 *Aaron Bedra, Steven Bristol, Jonathan Wiess*
951
952 * Added first/last methods to associations/named_scope. Resolved #226. *Ryan Bates*
953

955
956 * Added protection against duplicate migration names (Aslak Hellesøy) *#112*
957
958 * 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*
959
960 * 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*
961
962 * Added change_table for migrations (Jeff Dean) [#71]. Example:
963
964 change_table :videos do |t|
965 t.timestamps # adds created_at, updated_at
966 t.belongs_to :goat # adds goat_id integer
967 t.string :name, :email, :limit => 20 # adds name and email both with a 20 char limit
968 t.remove :name, :email # removes the name and email columns
969 end
970
971 * Fixed has_many :through .create with no parameters caused a "can't dup NilClass" error (Steven Soroka) *#85*
972
973 * Added block-setting of attributes for Base.create like Base.new already has (Adam Meehan) *#39*
974
975 * Fixed that pessimistic locking you reference the quoted table name (Josh Susser) *#67*
976
977 * Fixed that change_column should be able to use :null => true on a field that formerly had false [Nate Wiger] *#26*
978
979 * Added that the MySQL adapter should map integer to either smallint, int, or bigint depending on the :limit just like PostgreSQL *David Heinemeier Hansson*
980
981 * Change validates_uniqueness_of :case_sensitive option default back to true (from [9160]). Love your database columns, don't LOWER them. *Rick Olson*
982
983 * Add support for interleaving migrations by storing which migrations have run in the new schema_migrations table. Closes #11493 *Jordi Bunster*
984
985 * ActiveRecord::Base#sum defaults to 0 if no rows are returned. Closes #11550 *Kamal Fariz Mahyuddin*
986
987 * Ensure that respond_to? considers dynamic finder methods. Closes #11538. *James Mead*
988
989 * Ensure that save on parent object fails for invalid has_one association. Closes #10518. *Pratik Naik*
990
991 * Remove duplicate code from associations. *Pratik Naik*
992
993 * Refactor HasManyThroughAssociation to inherit from HasManyAssociation. Association callbacks and <association>_ids= now work with hm:t. #11516 *Ruy Asan*
994
995 * Ensure HABTM#create and HABTM#build do not load entire association. *Pratik Naik*
996
997 * Improve documentation. *Xavier Noria, Jack Danger Canty, leethal*
998
999 * Tweak ActiveRecord::Base#to_json to include a root value in the returned hash: {"post": {"title": ...}} *Rick Olson*
1000
1001 Post.find(1).to_json # => {"title": ...}
1002 config.active_record.include_root_in_json = true
1003 Post.find(1).to_json # => {"post": {"title": ...}}
1004
1005 * Add efficient #include? to AssociationCollection (for has_many/has_many :through/habtm). *stopdropandrew*
1006
1007 * PostgreSQL: create_ and drop_database support. #9042 *ez, pedz, Nick Sieger*
1008
1009 * Ensure that validates_uniqueness_of works with with_scope. Closes #9235. *Nik Wakelin, cavalle*
1010
1011 * Partial updates include only unsaved attributes. Off by default; set YourClass.partial_updates = true to enable. *Jeremy Kemper*
1012
1013 * Removing unnecessary uses_tzinfo helper from tests, given that TZInfo is now bundled *Geoff Buesing*
1014
1015 * Fixed that validates_size_of :within works in associations #11295, #10019 *cavalle*
1016
1017 * Track changes to unsaved attributes. *Jeremy Kemper*
1018
1019 * Switched to UTC-timebased version numbers for migrations and the schema.

1312 belongs_to :article, :counter_cache => :comments_count
1313 end

1335 * Added ActiveRecord::Base#to_json/from_json *David Heinemeier Hansson, Cheah Chu Yeow*
1336

1341
1342 * Define dynamic finders as real methods after first usage. *bscofield*

1354 * Extract Firebird, FrontBase, and OpenBase adapters into gems. #9508, #9509, #9510 *Jeremy Kemper*
1355
1356 * RubyGem database adapters: expects a gem named activerecord-<database>-adapter with active_record/connection_adapters/<database>_adapter.rb in its load path. *Jeremy Kemper*

1379
1380 For more information see: http://dev.rubyonrails.org/ticket/8049
1381
1382 * Don't clobber includes passed to has_many.count *Jack Danger Canty*
1383
1384 * Make sure has_many uses :include when counting *Jack Danger Canty*
1385
1386 * Change the implementation of ActiveRecord's attribute reader and writer methods *Michael Koziarski*
1387 - Generate Reader and Writer methods which cache attribute values in hashes. This is to avoid repeatedly parsing the same date or integer columns.
1388 - 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.
1389 - Move method definition to the class, instead of the instance
1390 - Always generate the readers, writers and predicate methods.
1391
1392 * Perform a deep #dup on query cache results so that modifying activerecord attributes does not modify the cached attributes. *Rick Olson*

1397
1398 def using_open_id?
1399 !identity_url.blank?
1400 end
1401
1402 validates_presence_of :identity_url, :if => using_open_id?
1403 validates_presence_of :username, :unless => using_open_id?
1404 validates_presence_of :password, :unless => using_open_id?
1405
1406 * Fix #count on a has_many :through association so that it recognizes the :uniq option. Closes #8801 *Pratik Naik*
1407
1408 * Fix and properly document/test count(column_name) usage. Closes #8999 *Pratik Naik*
1409
1410 * Remove deprecated count(conditions=nil, joins=nil) usage. Closes #8993 *Pratik Naik*
1411
1412 * Change belongs_to so that the foreign_key assumption is taken from the association name, not the class name. Closes #8992 *Josh Susser*
1413
1414 OLD
1415 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is user_id
1416
1417 NEW

1451
1452 * Quickref for association methods. #7723 *marclove, Mindsweeper*
1453
1454 * Calculations: return nil average instead of 0 when there are no rows to average. #8298 *davidw*
1455
1456 * acts_as_nested_set: direct_children is sorted correctly. #4761 *Josh Peek, rails@33lc0.net*

1475
1476 * Find with a list of ids supports limit/offset. #8437 *hrudududu*
1477
1478 * Optimistic locking: revert the lock version when an update fails. #7840 *plang*
1479
1480 * Migrations: add_column supports custom column types. #7742 *jsgarvin, Theory*
1481
1482 * Load database adapters on demand. Eliminates config.connection_adapters and RAILS_CONNECTION_ADAPTERS. Add your lib directory to the $LOAD_PATH and put your custom adapter in lib/active_record/connection_adapters/adaptername_adapter.rb. This way you can provide custom adapters as plugins or gems without modifying Rails. *Jeremy Kemper*
1483
1484 * Ensure that associations with :dependent => :delete_all respect :conditions option. Closes #8034 *Jack Danger Canty, Josh Peek, Rick Olson*

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

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

1544
1545 * SQLite: binary escaping works with $KCODE='u'. #7862 *tsuka*
1546
1547 * Base#to_xml supports serialized attributes. #7502 *jonathan*
1548
1549 * Base.update_all :order and :limit options. Useful for MySQL updates that must be ordered to avoid violating unique constraints. *Jeremy Kemper*
1550
1551 * Remove deprecated object transactions. People relying on this functionality should install the object_transactions plugin at http://code.bitsweat.net/svn/object_transactions. Closes #5637 *Michael Koziarski, Jeremy Kemper*
1552
1553 * PostgreSQL: remove DateTime -> Time downcast. Warning: do not enable translate_results for the C bindings if you have timestamps outside Time's domain. *Jeremy Kemper*
1554
1555 * find_or_create_by_* takes a hash so you can create with more attributes than are in the method name. For example, Person.find_or_create_by_name(:name => 'Henry', :comments => 'Hi new user!') is equivalent to Person.find_by_name('Henry') || Person.create(:name => 'Henry', :comments => 'Hi new user!'). #7368 *Josh Susser*
1556
1557 * Make sure with_scope takes both :select and :joins into account when setting :readonly. Allows you to save records you retrieve using method_missing on a has_many :through associations. *Michael Koziarski*
1558
1559 * Allow a polymorphic :source for has_many :through associations. Closes #7143 *protocool*
1560
1561 * Consistent public/protected/private visibility for chained methods. #7813 *Dan Manges*
1562

1564
1565 * Consistently quote primary key column names. #7763 *toolmantim*
1566
1567 * Fixtures: fix YAML ordered map support. #2665 *Manuel Holtgrewe, nfbuckley*
1568
1569 * DateTimes assume the default timezone. #7764 *Geoff Buesing*
1570
1571 * Sybase: hide timestamp columns since they're inherently read-only. #7716 *Mike Joyce*
1572
1573 * Oracle: overflow Time to DateTime. #7718 *Michael Schoen*
1574
1575 * PostgreSQL: don't use async_exec and async_query with postgres-pr. #7727, #7762 *flowdelic, toolmantim*
1576
1577 * Fix has_many :through << with custom foreign keys. #6466, #7153 *naffis, Rich Collins*
1578
1579 * Test DateTime native type in migrations, including an edge case with dates
1580 during calendar reform. #7649, #7724 *fedot, Geoff Buesing*
1581
1582 * SQLServer: correctly schema-dump tables with no indexes or descending indexes. #7333, #7703 *Jakob Skjerning, Tom Ward*
1583
1584 * SQLServer: recognize real column type as Ruby float. #7057 *sethladd, Tom Ward*
1585
1586 * Added fixtures :all as a way of loading all fixtures in the fixture directory at once #7214 *Manfred Stienstra*
1587
1588 * Added database connection as a yield parameter to ActiveRecord::Base.transaction so you can manually rollback [David Heinemeier Hansson]. Example:
1589
1590 transaction do |transaction|
1591 david.withdrawal(100)
1592 mary.deposit(100)
1593 transaction.rollback! # rolls back the transaction that was otherwise going to be successful
1594 end
1595
1596 * Made increment_counter/decrement_counter play nicely with optimistic locking, and added a more general update_counters method *Jamis Buck*
1597
1598 * 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*
1599 Task.cache { Task.find(1); Task.find(1) } # => 1 query
1600
1601 * 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*
1602
1603 * Oracle: fix lob and text default handling. #7344 *gfriedrich, Michael Schoen*
1604
1605 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
1606
1607 * MySQL: blob and text columns may not have defaults in 5.x. Update fixtures schema for strict mode. #6695 *Dan Kubb*
1608
1609 * 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*
1610
1611 * MySQL: SET SQL_AUTO_IS_NULL=0 so 'where id is null' doesn't select the last inserted id. #6778 *Jonathan Viney, timc*
1612
1613 * Use Date#to_s(:db) for quoted dates. #7411 *Michael Schoen*
1614
1615 * Don't create instance writer methods for class attributes. Closes #7401 *Rick Olson*
1616
1617 * Docs: validations examples. #7343 *zackchandler*
1618
1619 * Add missing tests ensuring callbacks work with class inheritance. Closes #7339 *sandofsky*
1620
1621 * Fixtures use the table name and connection from set_fixture_class. #7330 *Anthony Eden*
1622
1623 * Remove useless code in #attribute_present? since 0 != blank?. Closes #7249 *Josh Susser*
1624
1625 * Fix minor doc typos. Closes #7157 *Josh Susser*
1626
1627 * Fix incorrect usage of #classify when creating the eager loading join statement. Closes #7044 *Josh Susser*

1633 * Make sure sqlite3 driver closes open connections on disconnect *Rob Rasmussen*
1634
1635 * [DOC] clear up some ambiguity with the way has_and_belongs_to_many creates the default join table name. #7072 *Jeremy McAnally*
1636
1637 * change_column accepts :default => nil. Skip column options for primary keys. #6956, #7048 *Dan Manges, Jeremy Kemper*
1638
1639 * 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*
1640
1641 * Oracle: create_table takes a :sequence_name option to override the 'tablename_seq' default. #7000 *Michael Schoen*
1642
1643 * MySQL: retain SSL settings on reconnect. #6976 *randyv2*
1644
1645 * Apply scoping during initialize instead of create. Fixes setting of foreign key when using find_or_initialize_by with scoping. *Cody Fauser*
1646
1647 * SQLServer: handle [quoted] table names. #6635 *rrich*
1648
1649 * acts_as_nested_set works with single-table inheritance. #6030 *Josh Susser*
1650
1651 * PostgreSQL, Oracle: correctly perform eager finds with :limit and :order. #4668, #7021 *eventualbuddha, Michael Schoen*
1652
1653 * Pass a range in :conditions to use the SQL BETWEEN operator. #6974 *Dan Manges*
1654 Student.find(:all, :conditions => { :grade => 9..12 })
1655
1656 * Fix the Oracle adapter for serialized attributes stored in CLOBs. Closes #6825 *mschoen, tdfowler*
1657
1658 * [DOCS] Apply more documentation for ActiveRecord Reflection. Closes #4055 *Robby Russell*
1659
1660 * [DOCS] Document :allow_nil option of #validate_uniqueness_of. Closes #3143 *Caio Chassot*
1661
1662 * Bring the sybase adapter up to scratch for 1.2 release. *jsheets*
1663
1664 * Rollback new_record? and id when an exception is raised in a save callback. #6910 *Ben Curren, outerim*
1665
1666 * Pushing a record on an association collection doesn't unnecessarily load all the associated records. *Obie Fernandez, Jeremy Kemper*
1667
1668 * Oracle: fix connection reset failure. #6846 *leonlleslie*
1669
1670 * Subclass instantiation doesn't try to explicitly require the corresponding subclass. #6840 *leei, Jeremy Kemper*
1671
1672 * 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*
1673
1674 * 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*
1675
1676 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
1677
1678 * Add AssociationCollection#create! to be consistent with AssociationCollection#create when dealing with a foreign key that is a protected attribute *Cody Fauser*
1679
1680 * 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*
1681
1682 * Change fixture_path to a class inheritable accessor allowing test cases to have their own custom set of fixtures. #6672 *Zach Dennis*
1683
1684 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
1685
1686 * Simplify query_attribute by typecasting the attribute value and checking whether it's nil, false, zero or blank. #6659 *Jonathan Viney*
1687
1688 * 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*
1689
1690 * Run validations in the order they were declared. #6657 *obrie*
1691
1692 * 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*
1693
1694 * Simplify association proxy implementation by factoring construct_scope out of method_missing. #6643 *martin*
1695
1696 * Oracle: automatically detect the primary key. #6594 *vesaria, Michael Schoen*
1697
1698 * 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*
1699
1700 * Don't inspect unloaded associations. #2905 *lmarlow*

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

1726
1727 * 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*
1728
1729 * Make add_column use the options hash with the Sqlite Adapter. Closes #6464 *obrie*
1730
1731 * Document other options available to migration's add_column. #6419 *grg*
1732

1742
1743 * Add #delete support to has_many :through associations. Closes #6049 *Martin Landers*
1744
1745 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
1746
1747 * 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*
1748
1749 * 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*
1750
1751 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*
1752
1753 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
1754
1755 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
1756
1757 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
1758
1759 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
1760
1761 * 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*
1762
1763 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
1764
1765 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*
1766
1767 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*

1776
1777 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
1778
1779 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
1780
1781 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
1782
1783 * 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*
1784
1785 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
1786
1787 * Document validates_presences_of behavior with booleans: you probably want validates_inclusion_of :attr, :in => [true, false]. #2253 *Bob Silva*
1788
1789 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
1790
1791 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
1792
1793 * Deprecation: update docs. #5998 *Jakob Skjerning, Kevin Clark*
1794
1795 * Add some XmlSerialization tests for ActiveRecord *Rick Olson*
1796
1797 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
1798
1799 * Tighten rescue clauses. #5985 *james@grayproductions.net*
1800
1801 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
1802
1803 * 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*
1804
1805 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
1806

1818
1819 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
1820
1821 * 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*
1822
1823 * 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*
1824
1825 # Create a tagging to associate the post and tag.
1826 post.tags << Tag.find_by_name('old')
1827 post.tags.create! :name => 'general'
1828
1829 # Would have been:
1830 post.taggings.create!(:tag => Tag.find_by_name('finally')
1831 transaction do
1832 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
1833 end

1838
1839 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
1840 Example: Invoice::Lineitem is given table name invoice_lineitems
1841
1842 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
1843 # people_active_last_name_index, people_active_deactivated_at_index
1844 add_index :people, [:active, :last_name]
1845 add_index :people, [:active, :deactivated_at]
1846 remove_index :people, [:active, :last_name]
1847 remove_index :people, [:active, :deactivated_at]
1848
1849 WARNING: backward-incompatibility. Multicolumn indexes created before this
1850 revision were named using the first column name only. Now they're uniquely
1851 named using all indexed columns.
1852
1853 To remove an old multicolumn index, remove_index :table_name, :first_column
1854
1855 * Fix for deep includes on the same association. *richcollins@gmail.com*
1856
1857 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
1858
1859 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
1860
1861 * Document find's :from option. Closes #5762. *andrew@redlinesoftware.com*
1862
1863 * 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*
1864
1865 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
1866
1867 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
1868
1869 * Add documentation for how to disable timestamps on a per model basis. Closes #5684. *matt@mattmargolis.net Marcel Molina Jr.*
1870
1871 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
1872
1873 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
1874
1875 * Formally deprecate the deprecated finders. *Michael Koziarski*

1888
1889 assert (Topic.exists?(:author_name => "David"))
1890 assert (Topic.exists?(:author_name => "Mary", :approved => true))
1891 assert (Topic.exists?(["parent_id = ?", 1]))
1892

1898
1899 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
1900
1901 * Allow #count through a has_many association to accept :include. *Dan Peterson*
1902

1910
1911 * Oracle: BigDecimal support. #5667 *Michael Schoen*

1913 * 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*
1914
1915 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*

1917 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
1918
1919 * Update callbacks documentation. #3970 *Robby Russell <robby@planetargon.com>*
1920
1921 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
1922
1923 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
1924
1925 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
1926
1927 * 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*
1928
1929 * 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*
1930
1931 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
1932
1933 * Minor tweak to improve performance of ActiveRecord::Base#to_param.
1934
1935 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
1936
1937 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
1938
1939 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
1940
1941 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
1942
1943 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
1944
1945 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
1946
1947 * 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*
1948 # Obtain an exclusive lock on person 1 so we can safely increment visits.
1949 Person.transaction do
1950 # select * from people where id=1 for update
1951 person = Person.find(1, :lock => true)
1952 person.visits += 1
1953 person.save!
1954 end
1955
1956 * 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*
1957
1958 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
1959
1960 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
1961
1962 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
1963
1964 * 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*
1965
1966 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
1967
1968 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
1969
1970 ...is the same as:
1971
1972 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
1973
1974 This makes it easier to pass in the options from a form or otherwise outside.
1975

1984
1985 * Fixed that count distinct should use the selected column even when using :include #5251 *anna@wota.jp*
1986
1987 * 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*
1988
1989 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
1990
1991 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
1992
1993 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
1994 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
1995 Foo.find(:first, :conditions => ['bar_id = ?', bar])
1996
1997 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
1998
1999 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
2000
2001 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*

2019
2020 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2021
2022 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2023
2024 * 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*

2199
2200 * Make add_column use the options hash with the Sqlite Adapter. Closes #6464 *obrie*
2201
2202 * Document other options available to migration's add_column. #6419 *grg*
2203
2204 * MySQL: all_hashes compatibility with old MysqlRes class. #6429, #6601 *Jeremy Kemper*
2205
2206 * Fix has_many :through to add the appropriate conditions when going through an association using STI. Closes #5783. *Jonathan Viney*
2207

2209
2210 * Restore eager condition interpolation, document it's differences *Rick Olson*
2211
2212 * 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*
2213
2214 * Add #delete support to has_many :through associations. Closes #6049 *Martin Landers*
2215
2216 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
2217
2218 * 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*
2219
2220 * 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*
2221
2222 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*
2223
2224 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
2225
2226 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
2227
2228 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
2229
2230 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
2231
2232 * 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*
2233
2234 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
2235
2236 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*
2237
2238 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*
2239

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

2341
2342 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
2343

2345
2346 assert (Topic.exists?(:author_name => "David"))
2347 assert (Topic.exists?(:author_name => "Mary", :approved => true))
2348 assert (Topic.exists?(["parent_id = ?", 1]))
2349

2353
2354 * Factor the attribute#{suffix} methods out of method_missing for easier extension. *Jeremy Kemper*
2355
2356 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
2357
2358 * Allow #count through a has_many association to accept :include. *Dan Peterson*
2359
2360 * create_table rdoc: suggest :id => false for habtm join tables. *Zed Shaw*
2361
2362 * PostgreSQL: return array fields as strings. #4664 *Robby Russell*
2363
2364 * 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*
2365
2366 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2367
2368 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2369
2370 * 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*
2371
2372 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*
2373
2374 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2375
2376 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2377
2378 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2379
2380 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2381
2382 * 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*
2383
2384 * 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*
2385
2386 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2387
2388 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2389
2390 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2391
2392 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2393
2394 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2395
2396 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2397
2398 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2399
2400 * 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*
2401 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2402 Person.transaction do
2403 # select * from people where id=1 for update
2404 person = Person.find(1, :lock => true)
2405 person.visits += 1
2406 person.save!
2407 end
2408
2409 * 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*
2410
2411 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2412
2413 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2414
2415 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2416
2417 * 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*
2418
2419 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2420
2421 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2422
2423 ...is the same as:
2424
2425 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2426
2427 This makes it easier to pass in the options from a form or otherwise outside.
2428
2429
2430 * Fixed issues with BLOB limits, charsets, and booleans for Firebird #5194, #5191, #5189 *kennethkunz@gmail.com*

2436 * Fixed problems with eager loading and counting on SQL Server #5212 *kajism@yahoo.com*
2437
2438 * Fixed that count distinct should use the selected column even when using :include #5251 *anna@wota.jp*
2439
2440 * 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*
2441
2442 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
2443
2444 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
2445
2446 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
2447 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
2448 Foo.find(:first, :conditions => ['bar_id = ?', bar])
2449
2450 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
2451
2452 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
2453
2454 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*
2455
2456 * Provide Association Extensions access to the instance that the association is being accessed from.
2457 Closes #4433 *Josh Susser*
2458
2459 * Update OpenBase adaterp's maintainer's email address. Closes #5176. *Derrick Spell*
2460
2461 * Add a quick note about :select and eagerly included associations. *Rick Olson*
2462
2463 * Add docs for the :as option in has_one associations. Closes #5144 *cdcarter@gmail.com*
2464
2465 * Fixed that has_many collections shouldn't load the entire association to do build or create *David Heinemeier Hansson*
2466
2467 * Added :allow_nil option for aggregations #5091 *Ian White*
2468
2469 * Fix Oracle boolean support and tests. Closes #5139. *Michael Schoen*
2470
2471 * 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*
2472
2473 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2474
2475 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2476
2477 * 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*
2478
2479 * Dates and times interpret empty strings as nil rather than 2000-01-01. #4830 *kajism@yahoo.com*

2592 * Added descriptive error messages for invalid has_many :through associations: going through :has_one or :has_and_belongs_to_many *Rick Olson*
2593
2594 * Added support for going through a polymorphic has_many association: (closes #4401) *Rick Olson*
2595
2596 class PhotoCollection < ActiveRecord::Base
2597 has_many :photos, :as => :photographic
2598 belongs_to :firm
2599 end
2600
2601 class Firm < ActiveRecord::Base
2602 has_many :photo_collections
2603 has_many :photos, :through => :photo_collections
2604 end
2605
2606 * Multiple fixes and optimizations in PostgreSQL adapter, allowing ruby-postgres gem to work properly. *ruben.nine@gmail.com*
2607
2608 * Fixed that AssociationCollection#delete_all should work even if the records of the association are not loaded yet. *Florian Weber*
2609
2610 * Changed those private ActiveRecord methods to take optional third argument :auto instead of nil for performance optimizations. (closes #4456) *Stefan*
2611
2612 * Private ActiveRecord methods add_limit!, add_joins!, and add_conditions! take an OPTIONAL third argument 'scope' (closes #4456) *Rick Olson*
2613
2614 * DEPRECATED: Using additional attributes on has_and_belongs_to_many associations. Instead upgrade your association to be a real join model *David Heinemeier Hansson*
2615
2616 * Fixed that records returned from has_and_belongs_to_many associations with additional attributes should be marked as read only (fixes #4512) *David Heinemeier Hansson*
2617
2618 * Do not implicitly mark recordss of has_many :through as readonly but do mark habtm records as readonly (eventually only on join tables without rich attributes). *Marcel Mollina Jr.*
2619
2620 * Fixed broken OCIAdapter #4457 *Michael Schoen*
2621
2622
2623 ## 1.14.0 (March 27th, 2006) ##
2624
2625 * Replace 'rescue Object' with a finer grained rescue. Closes #4431. *Nicholas Seckar*
2626
2627 * Fixed eager loading so that an aliased table cannot clash with a has_and_belongs_to_many join table *Rick Olson*
2628
2629 * Add support for :include to with_scope *andrew@redlinesoftware.com*
2630
2631 * Support the use of public synonyms with the Oracle adapter; required ruby-oci8 v0.1.14 #4390 *Michael Schoen*
2632
2633 * Change periods (.) in table aliases to _'s. Closes #4251 *jeff@ministrycentered.com*
2634
2635 * Changed has_and_belongs_to_many join to INNER JOIN for Mysql 3.23.x. Closes #4348 *Rick Olson*
2636
2637 * Fixed issue that kept :select options from being scoped *Rick Olson*
2638
2639 * Fixed db_schema_import when binary types are present #3101 *David Heinemeier Hansson*
2640
2641 * Fixed that MySQL enums should always be returned as strings #3501 *David Heinemeier Hansson*
2642
2643 * Change has_many :through to use the :source option to specify the source association. :class_name is now ignored. *Rick Olson*
2644
2645 class Connection < ActiveRecord::Base
2646 belongs_to :user
2647 belongs_to :channel
2648 end
2649
2650 class Channel < ActiveRecord::Base
2651 has_many :connections
2652 has_many :contacts, :through => :connections, :class_name => 'User' # OLD
2653 has_many :contacts, :through => :connections, :source => :user # NEW
2654 end
2655
2656 * 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*
2657
2658 * Allow overriding of find parameters in scoped has_many :through calls *Rick Olson*
2659
2660 In this example, :include => false disables the default eager association from loading. :select changes the standard
2661 select clause. :joins specifies a join that is added to the end of the has_many :through query.
2662
2663 class Post < ActiveRecord::Base
2664 has_many :tags, :through => :taggings, :include => :tagging do
2665 def add_joins_and_select
2666 find :all, :select => 'tags.*, authors.id as author_id', :include => false,
2667 :joins => 'left outer join posts on taggings.taggable_id = posts.id left outer join authors on posts.author_id = authors.id'
2668 end
2669 end
2670 end
2671
2672 * 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*
2673
2674 * Don't classify the has_one class when eager loading, it is already singular. Add tests. (closes #4117) *Jonathan Viney*
2675
2676 * Quit ignoring default :include options in has_many :through calls *Mark James*
2677
2678 * Allow has_many :through associations to find the source association by setting a custom class (closes #4307) *Jonathan Viney*
2679
2680 * Eager Loading support added for has_many :through => :has_many associations (see below). *Rick Olson*
2681
2682 * Allow has_many :through to work on has_many associations (closes #3864) [sco@scottraymond.net] Example:
2683
2684 class Firm < ActiveRecord::Base
2685 has_many :clients
2686 has_many :invoices, :through => :clients
2687 end
2688
2689 class Client < ActiveRecord::Base
2690 belongs_to :firm
2691 has_many :invoices
2692 end
2693
2694 class Invoice < ActiveRecord::Base
2695 belongs_to :client
2696 end
2697
2698 * Raise error when trying to select many polymorphic objects with has_many :through or :include (closes #4226) *Josh Susser*
2699
2700 * Fixed has_many :through to include :conditions set on the :through association. closes #4020 *Jonathan Viney*
2701
2702 * 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*
2703
2704 * SQL Server adapter gets some love #4298 *Ryan Tomayko*
2705
2706 * 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*
2707
2708 * 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):
2709
2710 Author.find(:all, :include => { :posts => :special_comments }, :order => 'special_comments.body')
2711
2712 * Add AbstractAdapter#table_alias_for to create table aliases according to the rules of the current adapter. *Rick Olson*
2713
2714 * 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*
2715
2716 * Remove broken attempts at handling columns with a default of 'now()' in the postgresql adapter. #2257 *Michael Koziarski*
2717
2718 * 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*
2719
2720 * Fixed that Migration#execute would have the table name prefix appended to its query #4110 *mark.imbriaco@pobox.com*
2721
2722 * Make all tinyint(1) variants act like boolean in mysql (tinyint(1) unsigned, etc.) *Jamis Buck*
2723
2724 * Use association's :conditions when eager loading. [Jeremy Evans] #4144
2725
2726 * Alias the has_and_belongs_to_many join table on eager includes. #4106 *Jeremy Evans*
2727
2728 This statement would normally error because the projects_developers table is joined twice, and therefore joined_on would be ambiguous.
2729
2730 Developer.find(:all, :include => {:projects => :developers}, :conditions => 'join_project_developers.joined_on IS NOT NULL')
2731
2732 * Oracle adapter gets some love #4230 *Michael Schoen*
2733
2734 * Changes :text to CLOB rather than BLOB [Moses Hohman]
2735 * Fixes an issue with nil numeric length/scales (several)
2736 * Implements support for XMLTYPE columns [wilig / Kubo Takehiro]
2737 * Tweaks a unit test to get it all green again
2738 * Adds support for #current_database
2739
2740 * Added Base.abstract_class? that marks which classes are not part of the Active Record hierarchy #3704 *Rick Olson*
2741
2742 class CachedModel < ActiveRecord::Base
2743 self.abstract_class = true
2744 end
2745
2746 class Post < CachedModel
2747 end
2748
2749 CachedModel.abstract_class?
2750 => true
2751
2752 Post.abstract_class?
2753 => false
2754
2755 Post.base_class
2756 => Post
2757
2758 Post.table_name
2759 => 'posts'
2760
2761 * Allow :dependent options to be used with polymorphic joins. #3820 *Rick Olson*
2762
2763 class Foo < ActiveRecord::Base
2764 has_many :attachments, :as => :attachable, :dependent => :delete_all
2765 end
2766
2767 * Nicer error message on has_many :through when :through reflection can not be found. #4042 *court3nay*
2768
2769 * Upgrade to Transaction::Simple 1.3 *Jamis Buck*
2770
2771 * Catch FixtureClassNotFound when using instantiated fixtures on a fixture that has no ActiveRecord model *Rick Olson*
2772
2773 * Allow ordering of calculated results and/or grouped fields in calculations *solo@gatelys.com*
2774
2775 * Make ActiveRecord::Base#save! return true instead of nil on success. #4173 *johan@johansorensen.com*
2776
2777 * Dynamically set allow_concurrency. #4044 *Stefan Kaes*
2778
2779 * Added Base#to_xml that'll turn the current record into a XML representation [David Heinemeier Hansson]. Example:
2780
2781 topic.to_xml
2782
2783 ...returns:
2784
2785 <?xml version="1.0" encoding="UTF-8"?>
2786 <topic>

2800 ...and you can configure with:
2801
2802 topic.to_xml(:skip_instruct => true, :except => [ :id, bonus_time, :written_on, replies_count ])
2803
2804 ...that'll return:

2816 You can even do load first-level associations as part of the document:
2817
2818 firm.to_xml :include => [ :account, :clients ]
2819
2820 ...that'll return something like:

2842
2843 * Allow :counter_cache to take a column name for custom counter cache columns *Jamis Buck*
2844
2845 * Documentation fixes for :dependent *robby@planetargon.com*
2846
2847 * Stop the MySQL adapter crashing when views are present. #3782 *Jonathan Viney*
2848
2849 * Don't classify the belongs_to class, it is already singular #4117 *keithm@infused.org*
2850
2851 * 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*
2852
2853 * Fix quoting of inheritance column for STI eager loading #4098 *Jonathan Viney <jonathan@bluewire.net.nz>*
2854
2855 * Added smarter table aliasing for eager associations for multiple self joins #3580 *Rick Olson*
2856
2857 * The first time a table is referenced in a join, no alias is used.
2858 * After that, the parent class name and the reflection name are used.
2859
2860 Tree.find(:all, :include => :children) # LEFT OUTER JOIN trees AS tree_children ...
2861
2862 * Any additional join references get a numerical suffix like '_2', '_3', etc.
2863
2864 * 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.
2865
2866 * 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:
2867
2868 # cascaded in two levels
2869 >> Author.find(:all, :include=>{:posts=>:comments})
2870 => authors
2871 +- posts
2872 +- comments
2873
2874 # cascaded in two levels and normal association
2875 >> Author.find(:all, :include=>[{:posts=>:comments}, :categorizations])
2876 => authors
2877 +- posts
2878 +- comments
2879 +- categorizations
2880
2881 # cascaded in two levels with two has_many associations
2882 >> Author.find(:all, :include=>{:posts=>[:comments, :categorizations]})
2883 => authors
2884 +- posts
2885 +- comments
2886 +- categorizations
2887
2888 # cascaded in three levels
2889 >> Company.find(:all, :include=>{:groups=>{:members=>{:favorites}}})
2890 => companies
2891 +- groups
2892 +- members
2893 +- favorites
2894
2895 * Make counter cache work when replacing an association #3245 *eugenol@gmail.com*
2896
2897 * Make migrations verbose *Jamis Buck*
2898
2899 * Make counter_cache work with polymorphic belongs_to *Jamis Buck*
2900
2901 * Fixed that calling HasOneProxy#build_model repeatedly would cause saving to happen #4058 *anna@wota.jp*
2902
2903 * 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:
2904
2905 * Does not support DATE SQL column types; use DATETIME instead.
2906 * Date columns on HABTM join tables are returned as String, not Time.
2907 * Insertions are potentially broken for :polymorphic join tables
2908 * BLOB column access not yet fully supported
2909
2910 * Clear stale, cached connections left behind by defunct threads. *Jeremy Kemper*
2911
2912 * CHANGED DEFAULT: set ActiveRecord::Base.allow_concurrency to false. Most AR usage is in single-threaded applications. *Jeremy Kemper*
2913
2914 * Renamed the "oci" adapter to "oracle", but kept the old name as an alias #4017 *Michael Schoen*
2915
2916 * 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*
2917
2918 * Speed up class -> connection caching and stale connection verification. #3979 *Stefan Kaes*
2919
2920 * Add set_fixture_class to allow the use of table name accessors with models which use set_table_name. *Kevin Clark*
2921
2922 * Added that fixtures to placed in subdirectories of the main fixture files are also loaded #3937 *dblack@wobblini.net*
2923
2924 * Define attribute query methods to avoid method_missing calls. #3677 *Jonathan Viney*
2925
2926 * 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*
2927
2928 * Added support for nested scopes #3407 [anna@wota.jp]. Examples:
2929
2930 Developer.with_scope(:find => { :conditions => "salary > 10000", :limit => 10 }) do
2931 Developer.find(:all) # => SELECT * FROM developers WHERE (salary > 10000) LIMIT 10
2932
2933 # inner rule is used. (all previous parameters are ignored)
2934 Developer.with_exclusive_scope(:find => { :conditions => "name = 'Jamis'" }) do
2935 Developer.find(:all) # => SELECT * FROM developers WHERE (name = 'Jamis')
2936 end
2937
2938 # parameters are merged
2939 Developer.with_scope(:find => { :conditions => "name = 'Jamis'" }) do
2940 Developer.find(:all) # => SELECT * FROM developers WHERE (( salary > 10000 ) AND ( name = 'Jamis' )) LIMIT 10
2941 end
2942 end
2943
2944 * Fixed db2 connection with empty user_name and auth options #3622 *phurley@gmail.com*
2945
2946 * Fixed validates_length_of to work on UTF-8 strings by using characters instead of bytes #3699 *Masao Mutoh*
2947
2948 * Fixed that reflections would bleed across class boundaries in single-table inheritance setups #3796 *Lars Pind*
2949
2950 * 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:
2951
2952 Person.average :age
2953 Person.minimum :age
2954 Person.maximum :age
2955 Person.sum :salary, :group => :last_name
2956
2957 * Renamed Errors#count to Errors#size but kept an alias for the old name (and included an alias for length too) #3920 *Luke Redpath*
2958
2959 * Reflections don't attempt to resolve module nesting of association classes. Simplify type computation. *Jeremy Kemper*
2960
2961 * 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*
2962
2963 * Fixed that the schema_info table used by ActiveRecord::Schema.define should respect table pre- and suffixes #3834 *rubyonrails@atyp.de*
2964
2965 * 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*
2966
2967 * Correct syntax error in mysql DDL, and make AAACreateTablesTest run first *Bob Silva*
2968
2969 * Allow :include to be used with has_many :through associations #3611 *Michael Schoen*
2970
2971 * PostgreSQL: smarter schema dumps using pk_and_sequence_for(table). #2920 *Blair Zajac*
2972
2973 * SQLServer: more compatible limit/offset emulation. #3779 *Tom Ward*
2974
2975 * Polymorphic join support for has_one associations (has_one :foo, :as => :bar) #3785 *Rick Olson*
2976
2977 * PostgreSQL: correctly parse negative integer column defaults. #3776 *bellis@deepthought.org*
2978
2979 * Fix problems with count when used with :include *Jeremy Hopple and Kevin Clark*
2980
2981 * ActiveRecord::RecordInvalid now states which validations failed in its default error message *Tobias Lütke*
2982
2983 * Using AssociationCollection#build with arrays of hashes should call build, not create *David Heinemeier Hansson*
2984
2985 * Remove definition of reloadable? from ActiveRecord::Base to make way for new Reloadable code. *Nicholas Seckar*
2986
2987 * 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*
2988
2989 * Support the :column option for remove_index with the PostgreSQL adapter. #3661 *Shugo Maeda*
2990
2991 * Add documentation for add_index and remove_index. #3600 *Manfred Stienstra <m.stienstra@fngtps.com>*
2992
2993 * If the OCI library is not available, raise an exception indicating as much. #3593 *Michael Schoen*
2994
2995 * Add explicit :order in finder tests as postgresql orders results differently by default. #3577. *Rick Olson*
2996
2997 * Make dynamic finders honor additional passed in :conditions. #3569 *Oleg Pudeyev <pudeyo@rpi.edu>, Marcel Molina Jr.*
2998
2999 * Show a meaningful error when the DB2 adapter cannot be loaded due to missing dependencies. *Nicholas Seckar*
3000
3001 * Make .count work for has_many associations with multi line finder sql *Michael Schoen*
3002
3003 * Add AR::Base.base_class for querying the ancestor AR::Base subclass *Jamis Buck*
3004
3005 * Allow configuration of the column used for optimistic locking *wilsonb@gmail.com*
3006
3007 * Don't hardcode 'id' in acts as list. *ror@philippeapril.com*
