4c5b73f @tenderlove Merge pull request #4531 from exviva/pessimistic_with_lock
tenderlove authored
63 * Added a `with_lock` method to ActiveRecord objects, which starts
64 a transaction, locks the object (pessimistically) and yields to the block.
65 The method takes one (optional) parameter and passes it to `lock!`.
66
67 Before:
68
69 class Order < ActiveRecord::Base
70 def cancel!
71 transaction do
72 lock!
73 # ... cancelling logic
74 end

10834e9 @joshsusser changelog & docs for GeneratedFeatureMethods
joshsusser authored
169 * Generated association methods are created within a separate module to allow overriding and
170 composition using `super`. For a class named `MyModel`, the module is named
171 `MyModel::GeneratedFeatureMethods`. It is included into the model class immediately after
172 the `generated_attributes_methods` module defined in ActiveModel, so association methods
173 override attribute methods of the same name. *Josh Susser*

281272a @jonleighton Convert CHANGELOGs to Markdown format.
jonleighton authored
195 * Allow the :class_name option for associations to take a symbol (:Client) in addition to
196 a string ('Client').
197
198 This is to avoid confusing newbies, and to be consistent with the fact that other options
199 like :foreign_key already allow a symbol or a string.
200
201 *Jon Leighton*
202
203 * In development mode the db:drop task also drops the test database. For symmetry with
204 the db:create task. *Dmitriy Kiriyenko*
205
206 * Added ActiveRecord::Base.store for declaring simple single-column key/value stores *DHH*
207
208 class User < ActiveRecord::Base
209 store :settings, accessors: [ :color, :homepage ]
210 end
211
212 u = User.new(color: 'black', homepage: '37signals.com')
213 u.color # Accessor stored attribute
214 u.settings[:country] = 'Denmark' # Any attribute, even if not specified with an accessor
215
216
217 * MySQL: case-insensitive uniqueness validation avoids calling LOWER when
218 the column already uses a case-insensitive collation. Fixes #561.
219
220 *Joseph Palermo*
221
222 * Transactional fixtures enlist all active database connections. You can test
223 models on different connections without disabling transactional fixtures.
224
225 *Jeremy Kemper*
226
227 * Add first_or_create, first_or_create!, first_or_initialize methods to Active Record. This is a
228 better approach over the old find_or_create_by dynamic methods because it's clearer which
229 arguments are used to find the record and which are used to create it:
230
231 User.where(:first_name => "Scarlett").first_or_create!(:last_name => "Johansson")
232

307 ## Rails 3.1.1 (October 7, 2011) ##
308
309 * Add deprecation for the preload_associations method. Fixes #3022.
310
311 *Jon Leighton*
312
313 * Don't require a DB connection when loading a model that uses set_primary_key. GH #2807.
314
315 *Jon Leighton*
316
317 * Fix using select() with a habtm association, e.g. Person.friends.select(:name). GH #3030 and
318 \#2923.
319
320 *Hendy Tanata*
321
322 * Fix belongs_to polymorphic with custom primary key on target. GH #3104.
323
324 *Jon Leighton*
325
326 * CollectionProxy#replace should change the DB records rather than just mutating the array.
327 Fixes #3020.
328
329 *Jon Leighton*
330
331 * LRU cache in mysql and sqlite are now per-process caches.
332
333 * lib/active_record/connection_adapters/mysql_adapter.rb: LRU cache keys are per process id.
334 * lib/active_record/connection_adapters/sqlite_adapter.rb: ditto
335 *Aaron Patterson*
336
337 * Support bulk change_table in mysql2 adapter, as well as the mysql one. *Jon Leighton*
338
339 * If multiple parameters are sent representing a date, and some are blank, the
340 resulting object is nil. In previous releases those values defaulted to 1. This only affects existing but blank parameters, missing ones still raise an error. [Akira Matsuda]
341 * ActiveRecord::Base.establish_connection now takes a string that contains
342 a URI that specifies the connection configuration. For example:
343 ActiveRecord::Base.establish_connection 'postgres://localhost/foo'
344
345 * Active Record's dynamic finder will now raise the error if you passing in less number of arguments than what you call in method signature.
346
347 So if you were doing this and expecting the second argument to be nil:
348
349 User.find_by_username_and_group("sikachu")
350
351 You'll now get `ArgumentError: wrong number of arguments (1 for 2).` You'll then have to do this:
352
353 User.find_by_username_and_group("sikachu", nil)
354
355 *Prem Sichanugrist*
356
357
358 ## Rails 3.1.0 (August 30, 2011) ##
359
360 * Add a proxy_association method to association proxies, which can be called by association
361 extensions to access information about the association. This replaces proxy_owner etc with
362 proxy_association.owner.
363
364 *Jon Leighton*
365
366 * ActiveRecord::MacroReflection::AssociationReflection#build_record has a new method signature.
367
368 Before: def build_association(*options)
369 After: def build_association(*options, &block)
370
371 Users who are redefining this method to extend functionality should ensure that the block is
372 passed through to ActiveRecord::Base#new.
373
374 This change is necessary to fix https://github.com/rails/rails/issues/1842.
375
376 *Jon Leighton*
377
378 * AR#pluralize_table_names can be used to singularize/pluralize table name of an individual model:
379
380 class User < ActiveRecord::Base
381 self.pluralize_table_names = false
382 end
383
384 Previously this could only be set globally for all models through ActiveRecord::Base.pluralize_table_names. *Guillermo Iguaran*
385
386 * Add block setting of attributes to singular associations:
387
388 class User < ActiveRecord::Base
389 has_one :account
390 end
391
392 user.build_account{ |a| a.credit_limit => 100.0 }
393
394 The block is called after the instance has been initialized. *Andrew White*
395
396 * 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*
397
398 * CSV Fixtures are deprecated and support will be removed in Rails 3.2.0
399
400 * AR#new, AR#create, AR#create!, AR#update_attributes and AR#update_attributes! all accept a second hash as option that allows you
401 to specify which role to consider when assigning attributes. This is built on top of ActiveModel's
402 new mass assignment capabilities:
403
404 class Post < ActiveRecord::Base
405 attr_accessible :title
406 attr_accessible :title, :published_at, :as => :admin
407 end
408
409 Post.new(params[:post], :as => :admin)
410
411 assign_attributes() with similar API was also added and attributes=(params, guard) was deprecated.
412
413 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.
414
415 *Josh Kalderimis*
416
417 * default_scope can take a block, lambda, or any other object which responds to `call` for lazy
418 evaluation:
419
420 default_scope { ... }
421 default_scope lambda { ... }
422 default_scope method(:foo)
423
424 This feature was originally implemented by Tim Morgan, but was then removed in favour of
425 defining a 'default_scope' class method, but has now been added back in by Jon Leighton.
426 The relevant lighthouse ticket is #1812.
427
428 * Default scopes are now evaluated at the latest possible moment, to avoid problems where
429 scopes would be created which would implicitly contain the default scope, which would then
430 be impossible to get rid of via Model.unscoped.
431
432 Note that this means that if you are inspecting the internal structure of an
433 ActiveRecord::Relation, it will *not* contain the default scope, though the resulting
434 query will do. You can get a relation containing the default scope by calling
435 ActiveRecord#with_default_scope, though this is not part of the public API.
436
437 *Jon Leighton*
438
439 * If you wish to merge default scopes in special ways, it is recommended to define your default
440 scope as a class method and use the standard techniques for sharing code (inheritance, mixins,
441 etc.):
442
443 class Post < ActiveRecord::Base
444 def self.default_scope
445 where(:published => true).where(:hidden => false)
446 end
447 end
448
449 *Jon Leighton*
450
451 * PostgreSQL adapter only supports PostgreSQL version 8.2 and higher.
452
453 * ConnectionManagement middleware is changed to clean up the connection pool
454 after the rack body has been flushed.
455
456 * Added an update_column method on ActiveRecord. This new method updates a given attribute on an object, skipping validations and callbacks.
457 It is recommended to use #update_attribute unless you are sure you do not want to execute any callback, including the modification of
458 the updated_at column. It should not be called on new records.
459 Example:
460
461 User.first.update_column(:name, "sebastian") # => true
462
463 *Sebastian Martinez*
464
465 * Associations with a :through option can now use *any* association as the
466 through or source association, including other associations which have a
467 :through option and has_and_belongs_to_many associations
468
469 *Jon Leighton*
470
471 * The configuration for the current database connection is now accessible via
472 ActiveRecord::Base.connection_config. *fxn*
473
474 * limits and offsets are removed from COUNT queries unless both are supplied.
475 For example:
476
477 People.limit(1).count # => 'SELECT COUNT(*) FROM people'
478 People.offset(1).count # => 'SELECT COUNT(*) FROM people'
479 People.limit(1).offset(1).count # => 'SELECT COUNT(*) FROM people LIMIT 1 OFFSET 1'
480
481 *lighthouse #6262*
482
483 * ActiveRecord::Associations::AssociationProxy has been split. There is now an Association class
484 (and subclasses) which are responsible for operating on associations, and then a separate,
485 thin wrapper called CollectionProxy, which proxies collection associations.
486
487 This prevents namespace pollution, separates concerns, and will allow further refactorings.
488
489 Singular associations (has_one, belongs_to) no longer have a proxy at all. They simply return
490 the associated record or nil. This means that you should not use undocumented methods such
491 as bob.mother.create - use bob.create_mother instead.
492
493 *Jon Leighton*
494
495 * Make has_many :through associations work correctly when you build a record and then save it. This
496 requires you to set the :inverse_of option on the source reflection on the join model, like so:
497
498 class Post < ActiveRecord::Base
499 has_many :taggings
500 has_many :tags, :through => :taggings
501 end
502
503 class Tagging < ActiveRecord::Base
504 belongs_to :post
505 belongs_to :tag, :inverse_of => :tagging # :inverse_of must be set!
506 end
507
508 class Tag < ActiveRecord::Base
509 has_many :taggings
510 has_many :posts, :through => :taggings
511 end
512
513 post = Post.first
514 tag = post.tags.build :name => "ruby"
515 tag.save # will save a Taggable linking to the post
516
517 *Jon Leighton*
518
519 * Support the :dependent option on has_many :through associations. For historical and practical
520 reasons, :delete_all is the default deletion strategy employed by association.delete(*records),
521 despite the fact that the default strategy is :nullify for regular has_many. Also, this only
522 works at all if the source reflection is a belongs_to. For other situations, you should directly
523 modify the through association.
524
525 *Jon Leighton*
526
527 * Changed the behaviour of association.destroy for has_and_belongs_to_many and has_many :through.
528 From now on, 'destroy' or 'delete' on an association will be taken to mean 'get rid of the link',
529 not (necessarily) 'get rid of the associated records'.
530
531 Previously, has_and_belongs_to_many.destroy(*records) would destroy the records themselves. It
532 would not delete any records in the join table. Now, it deletes the records in the join table.
533
534 Previously, has_many_through.destroy(*records) would destroy the records themselves, and the
535 records in the join table. [Note: This has not always been the case; previous version of Rails
536 only deleted the records themselves.] Now, it destroys only the records in the join table.
537
538 Note that this change is backwards-incompatible to an extent, but there is unfortunately no
539 way to 'deprecate' it before changing it. The change is being made in order to have
540 consistency as to the meaning of 'destroy' or 'delete' across the different types of associations.
541
542 If you wish to destroy the records themselves, you can do records.association.each(&:destroy)
543
544 *Jon Leighton*
545
546 * 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*
547
548 Example:
549
550 change_table(:users, :bulk => true) do |t|
551 t.string :company_name
552 t.change :birthdate, :datetime
553 end
554
555 This will now result in:
556
557 ALTER TABLE `users` ADD COLUMN `company_name` varchar(255), CHANGE `updated_at` `updated_at` datetime DEFAULT NULL
558
559 * Removed support for accessing attributes on a has_and_belongs_to_many join table. This has been
560 documented as deprecated behaviour since April 2006. Please use has_many :through instead.
561 *Jon Leighton*
562
563 * Added a create_association! method for has_one and belongs_to associations. *Jon Leighton*
564
565 * Migration files generated from model and constructive migration generators
566 (for example, add_name_to_users) use the reversible migration's `change`
567 method instead of the ordinary `up` and `down` methods. *Prem Sichanugrist*
568
569 * Removed support for interpolating string SQL conditions on associations. Instead, you should
570 use a proc, like so:
571
572 Before:
573
574 has_many :things, :conditions => 'foo = #{bar}'
575
576 After:
577
578 has_many :things, :conditions => proc { "foo = #{bar}" }
579
580 Inside the proc, 'self' is the object which is the owner of the association, unless you are
581 eager loading the association, in which case 'self' is the class which the association is within.
582
583 You can have any "normal" conditions inside the proc, so the following will work too:
584
585 has_many :things, :conditions => proc { ["foo = ?", bar] }
586
587 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
588 'record' to get the record being inserted or deleted. This is now passed as an argument to
589 the proc.
590
591 * Added ActiveRecord::Base#has_secure_password (via ActiveModel::SecurePassword) to encapsulate dead-simple password usage with BCrypt encryption and salting [DHH]. Example:
592
593 # Schema: User(name:string, password_digest:string, password_salt:string)
594 class User < ActiveRecord::Base
595 has_secure_password
596 end
597
598 user = User.new(:name => "david", :password => "", :password_confirmation => "nomatch")
599 user.save # => false, password required
600 user.password = "mUc3m00RsqyRe"
601 user.save # => false, confirmation doesn't match
602 user.password_confirmation = "mUc3m00RsqyRe"
603 user.save # => true
604 user.authenticate("notright") # => false
605 user.authenticate("mUc3m00RsqyRe") # => user
606 User.find_by_name("david").try(:authenticate, "notright") # => nil
607 User.find_by_name("david").try(:authenticate, "mUc3m00RsqyRe") # => user
608
609
610 * When a model is generated add_index is added by default for belongs_to or references columns
611
612 rails g model post user:belongs_to will generate the following:
613
614 class CreatePosts < ActiveRecord::Migration
615 def up
616 create_table :posts do |t|
617 t.belongs_to :user
618 t.timestamps
619 end
620
621 add_index :posts, :user_id
622 end
623
624 def down
625 drop_table :posts
626 end
627 end
628
629 *Santiago Pastorino*
630
631 * Setting the id of a belongs_to object will update the reference to the
632 object. [#2989 state:resolved]
633 * ActiveRecord::Base#dup and ActiveRecord::Base#clone semantics have changed
634 to closer match normal Ruby dup and clone semantics.
635 * Calling ActiveRecord::Base#clone will result in a shallow copy of the record,
636 including copying the frozen state. No callbacks will be called.
637 * Calling ActiveRecord::Base#dup will duplicate the record, including calling
638 after initialize hooks. Frozen state will not be copied, and all associations will be cleared. A duped record will return true for new_record?, have a nil id field, and is saveable.
639 * Migrations can be defined as reversible, meaning that the migration system
640 will figure out how to reverse your migration. To use reversible migrations, just define the "change" method. For example:
641 class MyMigration < ActiveRecord::Migration
642 def change
643 create_table(:horses) do
644 t.column :content, :text
645 t.column :remind_at, :datetime
646 end
647 end
648 end
649
650 Some things cannot be automatically reversed for you. If you know how to reverse those things, you should define 'up' and 'down' in your migration. If you define something in `change` that cannot be reversed, an IrreversibleMigration exception will be raised when going down.
651 * Migrations should use instance methods rather than class methods:
652 class FooMigration < ActiveRecord::Migration
653 def up
654 ...
655 end
656 end
657
658 *Aaron Patterson*
659
660 * has_one maintains the association with separate after_create/after_update instead
661 of a single after_save. *fxn*
662
663 * The following code:
664
665 Model.limit(10).scoping { Model.count }
666
667 now generates the following SQL:
668
669 SELECT COUNT(*) FROM models LIMIT 10
670
671 This may not return what you want. Instead, you may with to do something
672 like this:
673
674 Model.limit(10).scoping { Model.all.size }
675

679 ## Rails 3.0.7 (April 18, 2011) ##
680
681 * Destroying records via nested attributes works independent of reject_if LH #6006 *Durran Jordan*
682
683 * Delegate any? and many? to Model.scoped for consistency *Andrew White*
684
685 * Quote the ORDER BY clause in batched finds - fixes #6620 *Andrew White*
686
687 * Change exists? so records are not instantiated - fixes #6127. This prevents after_find
688 and after_initialize callbacks being triggered when checking for record existence.
689 *Andrew White*
690
691 * Fix performance bug with attribute accessors which only occurred on Ruby 1.8.7, and ensure we
692 cache type-casted values when the column returned from the db contains non-standard chars.
693 *Jon Leighton*
694
695 * Fix a performance regression introduced here 86acbf1cc050c8fa8c74a10c735e467fb6fd7df8

699 ## Rails 3.0.6 (April 5, 2011) ##
700
701 * Un-deprecate reorder method *Sebastian Martinez*
702
703 * Extensions are applied when calling +except+ or +only+ on relations.
704 Thanks to Iain Hecker.
705
706 * Schemas set in set_table_name are respected by the mysql adapter. LH #5322
707
708 * Fixed a bug when empty? was called on a grouped Relation that wasn't loaded.
709 LH #5829
710
711 * Reapply extensions when using except and only. Thanks Iain Hecker.
712
713 * Binary data is escaped when being inserted to SQLite3 Databases. Thanks
714 Naruse!
715
716
717 ## Rails 3.0.5 (February 26, 2011) ##
718
719 * Model.where(:column => 1).where(:column => 2) will always produce an AND
720 query.
721 *Aaron Patterson*
722
723 * Deprecated support for interpolated association conditions in the form of :conditions => 'foo = #{bar}'.
724
725 Instead, you should use a proc, like so:
726
727 Before:
728
729 has_many :things, :conditions => 'foo = #{bar}'
730
731 After:
732
733 has_many :things, :conditions => proc { "foo = #{bar}" }
734
735 Inside the proc, 'self' is the object which is the owner of the association, unless you are
736 eager loading the association, in which case 'self' is the class which the association is within.
737
738 You can have any "normal" conditions inside the proc, so the following will work too:
739
740 has_many :things, :conditions => proc { ["foo = ?", bar] }
741
742 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
743 'record' to get the record being inserted or deleted. This is now passed as an argument to
744 the proc.
745
746 *Jon Leighton*
747
748
749 ## Rails 3.0.4 (February 8, 2011) ##
750
751 * Added deprecation warning for has_and_belongs_to_many associations where the join table has
752 additional attributes other than the keys. Access to these attributes is removed in 3.1.
753 Please use has_many :through instead. *Jon Leighton*
754
755
756 ## Rails 3.0.3 (November 16, 2010) ##
757
758 * Support find by class like this: Post.where(:name => Post)
759
760
761 ## Rails 3.0.2 (November 15, 2010) ##
762
763 * Dramatic speed increase (see: http://engineering.attinteractive.com/2010/10/arel-two-point-ohhhhh-yaaaaaa/) *Aaron Patterson*
764
765 * reorder is deprecated in favor of except(:order).order(...) *Santiago Pastorino*
766
767 * except is now AR public API
768
769 Model.order('name').except(:order).order('salary')
770
771 generates:
772
773 SELECT * FROM models ORDER BY salary
774
775 *Santiago Pastorino*
776
777 * The following code:
778
779 Model.limit(10).scoping { Model.count }
780
781 now generates the following SQL:
782
783 SELECT COUNT(*) FROM models LIMIT 10
784
785 This may not return what you want. Instead, you may with to do something
786 like this:
787
788 Model.limit(10).scoping { Model.all.size }
789
790 *Aaron Patterson*
791
792
793 ## Rails 3.0.1 (October 15, 2010) ##
794
795 * Introduce a fix for CVE-2010-3993
796
797
798 ## Rails 3.0.0 (August 29, 2010) ##
799
800 * Changed update_attribute to not run callbacks and update the record directly in the database *Neeraj Singh*
801
802 * Add scoping and unscoped as the syntax to replace the old with_scope and with_exclusive_scope *José Valim*
803
804 * New rake task, db:migrate:status, displays status of migrations #4947 *Kevin Skoglund*
805
806 * select and order for ActiveRecord now always concatenate nested calls. Use reorder if you want the original order to be overwritten *Santiago Pastorino*
807
808 * PostgreSQL: ensure the database time zone matches Ruby's time zone #4895 *Aaron Patterson*
809
810 * Fixed that ActiveRecord::Base.compute_type would swallow NoMethodError #4751 *Andrew Bloomgarden, Andrew White*
811
812 * Add index length support for MySQL. #1852 *Emili Parreno, Pratik Naik*
813
814 Example:
815
816 add_index(:accounts, :name, :name => 'by_name', :length => 10)
817 => CREATE INDEX by_name ON accounts(name(10))
818
819 add_index(:accounts, [:name, :surname], :name => 'by_name_surname', :length => {:name => 10, :surname => 15})
820 => CREATE INDEX by_name_surname ON accounts(name(10), surname(15))
821
822 * find_or_create_by_attr(value, ...) works when attr is protected. #4457 *Santiago Pastorino, Marc-André Lafortune*
823
824 * New callbacks: after_commit and after_rollback. Do expensive operations like image thumbnailing after_commit instead of after_save. #2991 *Brian Durand*
825
826 * 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*
827
828 * 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*
829
830 * PostgreSQL: drop support for old postgres driver. Use pg 0.9.0 or later. *Jeremy Kemper*
831
832 * Observers can prevent records from saving by returning false, just like before_save and friends. #4087 *Mislav Marohnić*
833
834 * Add Relation extensions. *Pratik Naik*
835
836 users = User.where(:admin => true).extending(User::AdminPowers)
837
838 latest_users = User.order('created_at DESC') do
839 def posts_count
840 Post.count(:user_id => to_a.map(&:id))
841 end
842 end
843
844 * To prefix the table names of all models in a module, define self.table_name_prefix on the module. #4032 *Andrew White*
845
846 * 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*
847
848 * 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*
849
850 * Allow relations to be used as scope.
851
852 class Item
853 scope :red, where(:colour => 'red')
854 end
855
856 Item.red.limit(10) # Ten red items
857
858 * Rename named_scope to scope. *Pratik Naik*
859
860 * Changed ActiveRecord::Base.store_full_sti_class to be true by default reflecting the previously announced Rails 3 default *DHH*
861
862 * Add Relation#except. *Pratik Naik*
863
864 one_red_item = Item.where(:colour => 'red').limit(1)
865 all_items = one_red_item.except(:where, :limit)
866
867 * Add Relation#delete_all. *Pratik Naik*
868
869 Item.where(:colour => 'red').delete_all
870
871 * Add Model.having and Relation#having. *Pratik Naik*
872
873 Developer.group("salary").having("sum(salary) > 10000").select("salary")
874
875 * Add Relation#count. *Pratik Naik*
876
877 legends = People.where("age > 100")
878 legends.count
879 legends.count(:age, :distinct => true)
880 legends.select('id').count
881
882 * Add Model.readonly and association_collection#readonly finder method. *Pratik Naik*
883
884 Post.readonly.to_a # Load all posts in readonly mode
885 @user.items.readonly(false).to_a # Load all the user items in writable mode
886
887 * Add .lock finder method *Pratik Naik*
888
889 User.lock.where(:name => 'lifo').to_a
890
891 old_items = Item.where("age > 100")
892 old_items.lock.each {|i| .. }
893
894 * Add Model.from and association_collection#from finder methods *Pratik Naik*
895
896 user = User.scoped
897 user.select('*').from('users, items')
898
899 * Add relation.destroy_all *Pratik Naik*
900
901 old_items = Item.where("age > 100")
902 old_items.destroy_all
903
904 * Add relation.exists? *Pratik Naik*
905
906 red_items = Item.where(:colours => 'red')
907 red_items.exists?
908 red_items.exists?(1)
909
910 * Add find(ids) to relations. *Pratik Naik*
911
912 old_users = User.order("age DESC")
913 old_users.find(1)
914 old_users.find(1, 2, 3)
915
916 * Add new finder methods to association collection. *Pratik Naik*
917
918 class User < ActiveRecord::Base
919 has_many :items
920 end
921
922 user = User.first
923 user.items.where(:items => {:colour => 'red'})
924 user.items.select('items.id')
925
926 * Add relation.reload to force reloading the records. *Pratik Naik*
927
928 topics = Topic.scoped
929 topics.to_a # force load
930 topics.first # returns a cached record
931 topics.reload
932 topics.first # Fetches a new record from the database
933
934 * Rename Model.conditions and relation.conditions to .where. *Pratik Naik*
935
936 Before :
937 User.conditions(:name => 'lifo')
938 User.select('id').conditions(["age > ?", 21])
939
940 Now :
941 User.where(:name => 'lifo')
942 User.select('id').where(["age > ?", 21])
943
944 * Add Model.select/group/order/limit/joins/conditions/preload/eager_load class methods returning a lazy relation. *Pratik Naik*
945
946 Examples :
947
948 posts = Post.select('id).order('name') # Returns a lazy relation
949 posts.each {|p| puts p.id } # Fires "select id from posts order by name"
950
951 * Model.scoped now returns a relation if invoked without any arguments. *Pratik Naik*
952
953 Example :
954
955 posts = Post.scoped
956 posts.size # Fires "select count(*) from posts" and returns the count
957 posts.each {|p| puts p.name } # Fires "select * from posts" and loads post objects
958
959 * Association inverses for belongs_to, has_one, and has_many. Optimization to reduce database queries. #3533 *Murray Steele*
960
961 # post.comments sets each comment's post without needing to :include
962 class Post < ActiveRecord::Base
963 has_many :comments, :inverse_of => :post
964 end
965
966 * MySQL: add_ and change_column support positioning. #3286 *Ben Marini*
967
968 * Reset your Active Record counter caches with the reset_counter_cache class method. #1211 *Mike Breen, Gabe da Silveira*
969
970 * Remove support for SQLite 2. Please upgrade to SQLite 3+ or install the plugin from git://github.com/rails/sqlite2_adapter.git *Pratik Naik*
971
972 * PostgreSQL: XML datatype support. #1874 *Leonardo Borges*
973
974 * 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*
975
976 * SQLite: drop support for 'dbfile' option in favor of 'database.' #2363 *Paul Hinze, Jeremy Kemper*
977
978 * Added :primary_key option to belongs_to associations. #765 *Szymon Nowak, Philip Hallstrom, Noel Rocha*
979 # employees.company_name references companies.name
980 Employee.belongs_to :company, :primary_key => 'name', :foreign_key => 'company_name'
981
982 * Implement #many? for NamedScope and AssociationCollection using #size. #1500 *Chris Kampmeier*
983
984 * Added :touch option to belongs_to associations that will touch the parent record when the current record is saved or destroyed *DHH*
985
986 * Added ActiveRecord::Base#touch to update the updated_at/on attributes (or another specified timestamp) with the current time *DHH*
987
988
989 ## 2.3.2 Final (March 15, 2009) ##
990
991 * Added ActiveRecord::Base.find_each and ActiveRecord::Base.find_in_batches for batch processing *DHH/Jamis Buck*
992
993 * Added that ActiveRecord::Base.exists? can be called with no arguments #1817 *Scott Taylor*
994
995 * Add Support for updating deeply nested models from a single form. #1202 *Eloy Duran*
996
997 class Book < ActiveRecord::Base
998 has_one :author
999 has_many :pages
1000
1001 accepts_nested_attributes_for :author, :pages

1411
1412 * Assigning an instance of a foreign class to a composed_of aggregate calls an optional conversion block. Refactor and simplify composed_of implementation. #6322 *brandon, Chris Cruft*
1413
1414 * Assigning nil to a composed_of aggregate also sets its immediate value to nil. #9843 *Chris Cruft*

1437 * find_and_(initialize|create)_by methods can now properly initialize protected attributes *Tobias Lütke*
1438
1439 * belongs_to infers the foreign key from the association name instead of from the class name. *Jeremy Kemper*
1440
1441 * PostgreSQL: support multiline default values. #7533 *Carl Lerche, aguynamedryan, Rein Henrichs, Tarmo Tänav*
1442
1443 * MySQL: fix change_column on not-null columns that don't accept dfeault values of ''. #6663 *Jonathan Viney, Tarmo Tänav*
1444
1445 * validates_uniqueness_of behaves well with abstract superclasses and

1465
1466 class Comment < ActiveRecord::Base
1467 # Automatically sets Article#comments_count as readonly.
1468 belongs_to :article, :counter_cache => :comments_count
1469 end
1470
1471 class Article < ActiveRecord::Base
1472 attr_readonly :approved_comments_count
1473 end
1474
1475 * Make size for has_many :through use counter cache if it exists. Closes #9734 *Xavier Shay*
1476
1477 * Remove DB2 adapter since IBM chooses to maintain their own adapter instead. *Jeremy Kemper*
1478
1479 * Extract Oracle, SQLServer, and Sybase adapters into gems. *Jeremy Kemper*
1480

1488
1489 * Added the possibility of using symbols in addition to concrete classes with ActiveRecord::Observer#observe. #3998 *Robby Russell, Tarmo Tänav*
1490
1491 * Added ActiveRecord::Base#to_json/from_json *David Heinemeier Hansson, Cheah Chu Yeow*
1492
1493 * Added ActiveRecord::Base#from_xml [David Heinemeier Hansson]. Example:
1494
1495 xml = "<person><name>David</name></person>"
1496 Person.new.from_xml(xml).name # => "David"
1497
1498 * Define dynamic finders as real methods after first usage. *bscofield*
1499
1500 * Deprecation: remove deprecated threaded_connections methods. Use allow_concurrency instead. *Jeremy Kemper*
1501
1502 * Associations macros accept extension blocks alongside modules. #9346 *Josh Peek*
1503
1504 * Speed up and simplify query caching. *Jeremy Kemper*

1509
1510 * Extract Firebird, FrontBase, and OpenBase adapters into gems. #9508, #9509, #9510 *Jeremy Kemper*
1511
1512 * RubyGem database adapters: expects a gem named activerecord-<database>-adapter with active_record/connection_adapters/<database>_adapter.rb in its load path. *Jeremy Kemper*
1513
1514 * Fixed that altering join tables in migrations would fail w/ sqlite3 #7453 *TimoMihaljov/brandon*

1516 * Fix association writer with :dependent => :nullify. #7314 *Jonathan Viney*
1517
1518 * OpenBase: update for new lib and latest Rails. Support migrations. #8748 *dcsesq*

1531
1532 * Fixed that eager loading queries and with_scope should respect the :group option *David Heinemeier Hansson*

1535
1536 For more information see: http://dev.rubyonrails.org/ticket/8049
1537
1538 * Don't clobber includes passed to has_many.count *Jack Danger Canty*
1539
1540 * Make sure has_many uses :include when counting *Jack Danger Canty*
1541
1542 * Change the implementation of ActiveRecord's attribute reader and writer methods *Michael Koziarski*
1543 - Generate Reader and Writer methods which cache attribute values in hashes. This is to avoid repeatedly parsing the same date or integer columns. - Change exception raised when users use find with :select then try to access a skipped column. Plugins could override missing_attribute() to lazily load the columns. - Move method definition to the class, instead of the instance - Always generate the readers, writers and predicate methods.
1544 * Perform a deep #dup on query cache results so that modifying activerecord attributes does not modify the cached attributes. *Rick Olson*
1545
1546 \# Ensure that has_many :through associations use a count query instead of loading the target when #size is called. Closes #8800 [Pratik Naik]
1547 * Added :unless clause to validations #8003 [monki]. Example:
1548
1549 def using_open_id?
1550 !identity_url.blank?
1551 end
1552
1553 validates_presence_of :identity_url, :if => using_open_id?
1554 validates_presence_of :username, :unless => using_open_id?
1555 validates_presence_of :password, :unless => using_open_id?
1556
1557 * Fix #count on a has_many :through association so that it recognizes the :uniq option. Closes #8801 *Pratik Naik*
1558
1559 * Fix and properly document/test count(column_name) usage. Closes #8999 *Pratik Naik*
1560
1561 * Remove deprecated count(conditions=nil, joins=nil) usage. Closes #8993 *Pratik Naik*
1562
1563 * Change belongs_to so that the foreign_key assumption is taken from the association name, not the class name. Closes #8992 *Josh Susser*
1564
1565 OLD
1566 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is user_id
1567
1568 NEW
1569 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is visitor_id
1570
1571 * Remove spurious tests from deprecated_associations_test, most of these aren't deprecated, and are duplicated in associations_test. Closes #8987 *Pratik Naik*
1572
1573 * Make create! on a has_many :through association return the association object. Not the collection. Closes #8786 *Pratik Naik*
1574
1575 * Move from select * to select tablename.* to avoid clobbering IDs. Closes #8889 *dasil003*
1576
1577 * Don't call unsupported methods on associated objects when using :include, :method with to_xml #7307, *Manfred Stienstra, jwilger*
1578
1579 * Define collection singular ids method for has_many :through associations. #8763 *Pratik Naik*

1581 * Array attribute conditions work with proxied association collections. #8318 *Kamal Fariz Mahyuddin, theamazingrando*
1582
1583 * Fix polymorphic has_one associations declared in an abstract class. #8638 *Pratik Naik, Dax Huiberts*
1584
1585 * Fixed validates_associated should not stop on the first error. #4276 *mrj, Manfred Stienstra, Josh Peek*
1586
1587 * Rollback if commit raises an exception. #8642 *kik, Jeremy Kemper*

1594
1595 * Fixtures: correctly delete and insert fixtures in a single transaction. #8553 *Michael Schuerig*
1596
1597 * Fixtures: people(:technomancy, :josh) returns both fixtures. #7880 *technomancy, Josh Peek*
1598
1599 * Calculations support non-numeric foreign keys. #8154 *Kamal Fariz Mahyuddin*
1600
1601 * with_scope is protected. #8524 *Josh Peek*
1602
1603 * Quickref for association methods. #7723 *marclove, Mindsweeper*
1604
1605 * Calculations: return nil average instead of 0 when there are no rows to average. #8298 *davidw*
1606
1607 * acts_as_nested_set: direct_children is sorted correctly. #4761 *Josh Peek, rails@33lc0.net*
1608
1609 * Raise an exception if both attr_protected and attr_accessible are declared. #8507 *stellsmi*
1610
1611 * SQLite, MySQL, PostgreSQL, Oracle: quote column names in column migration SQL statements. #8466 *marclove, lorenjohnson*
1612
1613 * Allow nil serialized attributes with a set class constraint. #7293 *sandofsky*
1614
1615 * Oracle: support binary fixtures. #7987 *Michael Schoen*
1616
1617 * Fixtures: pull fixture insertion into the database adapters. #7987 *Michael Schoen*
1618
1619 * Announce migration versions as they're performed. *Jeremy Kemper*

1626
1627 * Find with a list of ids supports limit/offset. #8437 *hrudududu*
1628

1631 * Migrations: add_column supports custom column types. #7742 *jsgarvin, Theory*
1632
1633 * 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*
1634
1635 * Ensure that associations with :dependent => :delete_all respect :conditions option. Closes #8034 *Jack Danger Canty, Josh Peek, Rick Olson*
1636

1655 * Add documentation caveat about when to use count_by_sql. *fearoffish*
1656
1657 * Enhance documentation for increment_counter and decrement_counter. *fearoffish*
1658
1659 * Provide brief introduction to what optimistic locking is. *fearoffish*
1660
1661 * Add documentation for :encoding option to mysql adapter. *marclove*
1662
1663 * Added short-hand declaration style to migrations (inspiration from Sexy Migrations, http://errtheblog.com/post/2381) [David Heinemeier Hansson]. Example:
1664
1665 create_table "products" do |t|
1666 t.column "shop_id", :integer
1667 t.column "creator_id", :integer
1668 t.column "name", :string, :default => "Untitled"
1669 t.column "value", :string, :default => "Untitled"
1670 t.column "created_at", :datetime
1671 t.column "updated_at", :datetime
1672 end
1673
1674 ...can now be written as:
1675
1676 create_table :products do |t|
1677 t.integer :shop_id, :creator_id
1678 t.string :name, :value, :default => "Untitled"
1679 t.timestamps
1680 end
1681
1682 * 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*
1683
1684 * Improve performance of calling .create on has_many :through associations. *evan*
1685
1686 * Improved cloning performance by relying less on exception raising #8159 *Blaine*
1687
1688 * Added ActiveRecord::Base.inspect to return a column-view like #<Post id:integer, title:string, body:text> *David Heinemeier Hansson*
1689
1690 * Added yielding of Builder instance for ActiveRecord::Base#to_xml calls *David Heinemeier Hansson*
1691
1692 * Small additions and fixes for ActiveRecord documentation. Closes #7342 *Jeremy McAnally*
1693
1694 * Add helpful debugging info to the ActiveRecord::StatementInvalid exception in ActiveRecord::ConnectionAdapters::SqliteAdapter#table_structure. Closes #7925. *court3nay*
1695
1696 * SQLite: binary escaping works with $KCODE='u'. #7862 *tsuka*
1697
1698 * Base#to_xml supports serialized attributes. #7502 *jonathan*
1699
1700 * Base.update_all :order and :limit options. Useful for MySQL updates that must be ordered to avoid violating unique constraints. *Jeremy Kemper*
1701
1702 * 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*
1703
1704 * 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*
1705
1706 * 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*
1707
1708 * 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*
1709
1710 * Allow a polymorphic :source for has_many :through associations. Closes #7143 *protocool*
1711
1712 * Consistent public/protected/private visibility for chained methods. #7813 *Dan Manges*
1713
1714 * Oracle: fix quoted primary keys and datetime overflow. #7798 *Michael Schoen*
1715
1716 * Consistently quote primary key column names. #7763 *toolmantim*
1717
1718 * Fixtures: fix YAML ordered map support. #2665 *Manuel Holtgrewe, nfbuckley*
1719
1720 * DateTimes assume the default timezone. #7764 *Geoff Buesing*
1721
1722 * Sybase: hide timestamp columns since they're inherently read-only. #7716 *Mike Joyce*
1723
1724 * Oracle: overflow Time to DateTime. #7718 *Michael Schoen*
1725
1726 * PostgreSQL: don't use async_exec and async_query with postgres-pr. #7727, #7762 *flowdelic, toolmantim*
1727
1728 * Fix has_many :through << with custom foreign keys. #6466, #7153 *naffis, Rich Collins*
1729
1730 * Test DateTime native type in migrations, including an edge case with dates
1731 during calendar reform. #7649, #7724 [fedot, Geoff Buesing]
1732 * SQLServer: correctly schema-dump tables with no indexes or descending indexes. #7333, #7703 *Jakob Skjerning, Tom Ward*
1733
1734 * SQLServer: recognize real column type as Ruby float. #7057 *sethladd, Tom Ward*
1735
1736 * Added fixtures :all as a way of loading all fixtures in the fixture directory at once #7214 *Manfred Stienstra*
1737
1738 * Added database connection as a yield parameter to ActiveRecord::Base.transaction so you can manually rollback [David Heinemeier Hansson]. Example:
1739
1740 transaction do |transaction|
1741 david.withdrawal(100)
1742 mary.deposit(100)
1743 transaction.rollback! # rolls back the transaction that was otherwise going to be successful
1744 end
1745
1746 * Made increment_counter/decrement_counter play nicely with optimistic locking, and added a more general update_counters method *Jamis Buck*
1747
1748 * 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*
1749 Task.cache { Task.find(1); Task.find(1) } # => 1 query
1750
1751 * 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*
1752
1753 * Oracle: fix lob and text default handling. #7344 *gfriedrich, Michael Schoen*
1754
1755 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
1756
1757 * MySQL: blob and text columns may not have defaults in 5.x. Update fixtures schema for strict mode. #6695 *Dan Kubb*
1758
1759 * 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*
1760
1761 * MySQL: SET SQL_AUTO_IS_NULL=0 so 'where id is null' doesn't select the last inserted id. #6778 *Jonathan Viney, timc*
1762
1763 * Use Date#to_s(:db) for quoted dates. #7411 *Michael Schoen*
1764
1765 * Don't create instance writer methods for class attributes. Closes #7401 *Rick Olson*
1766
1767 * Docs: validations examples. #7343 *zackchandler*
1768
1769 * Add missing tests ensuring callbacks work with class inheritance. Closes #7339 *sandofsky*
1770
1771 * Fixtures use the table name and connection from set_fixture_class. #7330 *Anthony Eden*
1772
1773 * Remove useless code in #attribute_present? since 0 != blank?. Closes #7249 *Josh Susser*
1774
1775 * Fix minor doc typos. Closes #7157 *Josh Susser*
1776
1777 * Fix incorrect usage of #classify when creating the eager loading join statement. Closes #7044 *Josh Susser*
1778
1779 * SQLServer: quote table name in indexes query. #2928 *keithm@infused.org*
1780
1781 * Subclasses of an abstract class work with single-table inheritance. #5704, #7284 *BertG, nick+rails@ag.arizona.edu*
1782
1783 * Make sure sqlite3 driver closes open connections on disconnect *Rob Rasmussen*
1784
1785 * [DOC] clear up some ambiguity with the way has_and_belongs_to_many creates the default join table name. #7072 *Jeremy McAnally*
1786
1787 * change_column accepts :default => nil. Skip column options for primary keys. #6956, #7048 *Dan Manges, Jeremy Kemper*
1788
1789 * 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*
1790
1791 * Oracle: create_table takes a :sequence_name option to override the 'tablename_seq' default. #7000 *Michael Schoen*
1792
1793 * MySQL: retain SSL settings on reconnect. #6976 *randyv2*
1794
1795 * Apply scoping during initialize instead of create. Fixes setting of foreign key when using find_or_initialize_by with scoping. *Cody Fauser*
1796
1797 * SQLServer: handle [quoted] table names. #6635 *rrich*
1798

1817
1818 * Oracle: fix connection reset failure. #6846 *leonlleslie*
1819
1820 * Subclass instantiation doesn't try to explicitly require the corresponding subclass. #6840 *leei, Jeremy Kemper*
1821
1822 * 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*
1823
1824 * 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*
1825
1826 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
1827
1828 * Add AssociationCollection#create! to be consistent with AssociationCollection#create when dealing with a foreign key that is a protected attribute *Cody Fauser*
1829
1830 * 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*
1831
1832 * Change fixture_path to a class inheritable accessor allowing test cases to have their own custom set of fixtures. #6672 *Zach Dennis*
1833
1834 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
1835
1836 * Simplify query_attribute by typecasting the attribute value and checking whether it's nil, false, zero or blank. #6659 *Jonathan Viney*
1837
1838 * 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*
1839
1840 * Run validations in the order they were declared. #6657 *obrie*
1841
1842 * 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*
1843
1844 * Simplify association proxy implementation by factoring construct_scope out of method_missing. #6643 *martin*
1845
1846 * Oracle: automatically detect the primary key. #6594 *vesaria, Michael Schoen*
1847
1848 * 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*
1849
1850 * Don't inspect unloaded associations. #2905 *lmarlow*

1853
1854 * Cache inheritance_column. #6592 *Stefan Kaes*
1855
1856 * Firebird: decimal/numeric support. #6408 *macrnic*
1857
1858 * make add_order a tad faster. #6567 *Stefan Kaes*

1863 find(:all, :conditions => { :topic_id => [1, 2, 3], :last_read => nil }
1864
1865 * 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*
1866
1867 * SQLite: fix calculations workaround, remove count(distinct) query rewrite, cleanup test connection scripts. *Jeremy Kemper*
1868

1878
1879 * Make add_column use the options hash with the Sqlite Adapter. Closes #6464 *obrie*
1880
1881 * Document other options available to migration's add_column. #6419 *grg*
1882
1883 * MySQL: all_hashes compatibility with old MysqlRes class. #6429, #6601 *Jeremy Kemper*
1884
1885 * Fix has_many :through to add the appropriate conditions when going through an association using STI. Closes #5783. *Jonathan Viney*

1892
1893 * Add #delete support to has_many :through associations. Closes #6049 *Martin Landers*
1894
1895 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
1896
1897 * 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*
1898

1903 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
1904
1905 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
1906
1907 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
1908
1909 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
1910
1911 * 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*
1912
1913 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
1914
1915 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*
1916
1917 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*
1918

1920
1921 * Add a :namespace option to AR::Base#to_xml *Michael Koziarski*

1924
1925 * Mock Time.now for more accurate Touch mixin tests. #6213 *Dan Peterson*
1926
1927 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
1928
1929 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
1930
1931 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
1932
1933 * 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*
1934
1935 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
1936
1937 * Document validates_presences_of behavior with booleans: you probably want validates_inclusion_of :attr, :in => [true, false]. #2253 *Bob Silva*
1938
1939 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
1940
1941 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
1942
1943 * Deprecation: update docs. #5998 *Jakob Skjerning, Kevin Clark*
1944
1945 * Add some XmlSerialization tests for ActiveRecord *Rick Olson*
1946
1947 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
1948
1949 * Tighten rescue clauses. #5985 *james@grayproductions.net*
1950
1951 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
1952
1953 * 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*
1954
1955 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
1956
1957 * 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*
1958
1959 * SQLServer: fix eager association test. #5901 *Tom Ward*
1960
1961 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
1962
1963 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
1964
1965 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*
1966
1967 * MySQL: update test schema for MySQL 5 strict mode. #5861 *Tom Ward*
1968
1969 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
1970
1971 * 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*
1972
1973 * 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*
1974
1975 # Create a tagging to associate the post and tag.
1976 post.tags << Tag.find_by_name('old')
1977 post.tags.create! :name => 'general'
1978
1979 # Would have been:
1980 post.taggings.create!(:tag => Tag.find_by_name('finally')
1981 transaction do
1982 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
1983 end
1984
1985 * Cache nil results for :included has_one associations also. #5787 *Michael Schoen*
1986
1987 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
1988
1989 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
1990 Example: Invoice::Lineitem is given table name invoice_lineitems
1991
1992 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
1993 # people_active_last_name_index, people_active_deactivated_at_index
1994 add_index :people, [:active, :last_name]
1995 add_index :people, [:active, :deactivated_at]
1996 remove_index :people, [:active, :last_name]
1997 remove_index :people, [:active, :deactivated_at]
1998
1999 WARNING: backward-incompatibility. Multicolumn indexes created before this
2000 revision were named using the first column name only. Now they're uniquely
2001 named using all indexed columns.
2002
2003 To remove an old multicolumn index, remove_index :table_name, :first_column
2004
2005 * Fix for deep includes on the same association. *richcollins@gmail.com*
2006
2007 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
2008
2009 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
2010
2011 * Document find's :from option. Closes #5762. *andrew@redlinesoftware.com*
2012
2013 * 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*
2014
2015 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
2016
2017 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
2018
2019 * Add documentation for how to disable timestamps on a per model basis. Closes #5684. *matt@mattmargolis.net Marcel Molina Jr.*
2020
2021 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
2022
2023 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
2024
2025 * Formally deprecate the deprecated finders. *Michael Koziarski*
2026
2027 * Formally deprecate rich associations. *Michael Koziarski*
2028
2029 * Fixed that default timezones for new / initialize should uphold utc setting #5709 *daniluk@yahoo.com*
2030
2031 * Fix announcement of very long migration names. #5722 *blake@near-time.com*
2032
2033 * The exists? class method should treat a string argument as an id rather than as conditions. #5698 *jeremy@planetargon.com*
2034
2035 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
2036
2037 * Added support for conditions on Base.exists? #5689 [Josh Peek]. Examples:
2038
2039 assert (Topic.exists?(:author_name => "David"))
2040 assert (Topic.exists?(:author_name => "Mary", :approved => true))
2041 assert (Topic.exists?(["parent_id = ?", 1]))
2042
2043 * Schema dumper quotes date :default values. *Dave Thomas*
2044
2045 * Calculate sum with SQL, not Enumerable on HasManyThrough Associations. *Dan Peterson*
2046
2047 * Factor the attribute#{suffix} methods out of method_missing for easier extension. *Jeremy Kemper*
2048
2049 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
2050
2051 * Allow #count through a has_many association to accept :include. *Dan Peterson*
2052
2053 * create_table rdoc: suggest :id => false for habtm join tables. *Zed Shaw*
2054
2055 * PostgreSQL: return array fields as strings. #4664 *Robby Russell*
2056
2057 * 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*
2058
2059 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2060
2061 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2062
2063 * 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*
2064
2065 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*
2066
2067 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2068
2069 * Update callbacks documentation. #3970 *Robby Russell <robby@planetargon.com>*
2070
2071 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2072
2073 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2074
2075 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2076
2077 * 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*
2078
2079 * 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*
2080
2081 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2082
2083 * Minor tweak to improve performance of ActiveRecord::Base#to_param.
2084
2085 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2086
2087 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2088
2089 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2090
2091 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2092
2093 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2094
2095 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2096
2097 * 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*
2098 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2099 Person.transaction do
2100 # select * from people where id=1 for update
2101 person = Person.find(1, :lock => true)
2102 person.visits += 1
2103 person.save!
2104 end
2105
2106 * 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*
2107
2108 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2109
2110 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2111
2112 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2113
2114 * 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*
2115
2116 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2117
2118 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2119
2120 ...is the same as:
2121 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2122
2123 This makes it easier to pass in the options from a form or otherwise outside.
2124
2125
2126 * Fixed issues with BLOB limits, charsets, and booleans for Firebird #5194, #5191, #5189 *kennethkunz@gmail.com*

2129
2130 * Fixed migration trouble with SQLite when NOT NULL is used in the new definition #5215 *greg@lapcominc.com*
2131
2132 * Fixed problems with eager loading and counting on SQL Server #5212 *kajism@yahoo.com*
2133
2134 * Fixed that count distinct should use the selected column even when using :include #5251 *anna@wota.jp*
2135
2136 * 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*
2137
2138 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
2139
2140 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
2141
2142 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
2143 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
2144 Foo.find(:first, :conditions => ['bar_id = ?', bar])
2145
2146 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
2147
2148 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
2149
2150 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*
2151
2152 * Provide Association Extensions access to the instance that the association is being accessed from.
2153 Closes #4433 *Josh Susser*
2154
2155 * Update OpenBase adaterp's maintainer's email address. Closes #5176. *Derrick Spell*
2156
2157 * Add a quick note about :select and eagerly included associations. *Rick Olson*
2158
2159 * Add docs for the :as option in has_one associations. Closes #5144 *cdcarter@gmail.com*
2160
2161 * Fixed that has_many collections shouldn't load the entire association to do build or create *David Heinemeier Hansson*
2162
2163 * Added :allow_nil option for aggregations #5091 *Ian White*
2164
2165 * Fix Oracle boolean support and tests. Closes #5139. *Michael Schoen*
2166
2167 * 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*
2168
2169 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2170
2171 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2172
2173 * 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*
2174
2175 * Dates and times interpret empty strings as nil rather than 2000-01-01. #4830 *kajism@yahoo.com*
2176
2177 * Allow :uniq => true with has_many :through associations. *Jeremy Kemper*

2273
2274 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
2275
2276 * 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*
2277

2293
2294 * change_column accepts :default => nil. Skip column options for primary keys. #6956, #7048 *Dan Manges, Jeremy Kemper*
2295

2319
2320 * 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*
2321
2322 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
2323

2368
2369 * 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*
2370
2371 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*

2373 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
2374
2375 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
2376
2377 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
2378
2379 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
2380
2381 * 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*
2382
2383 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
2384

2396
2397 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
2398
2399 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
2400
2401 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
2402
2403 * 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*
2404
2405 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
2406
2407 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
2408
2409 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
2410
2411 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
2412
2413 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
2414
2415 * 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*
2416
2417 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
2418
2419 * 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*
2420
2421 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
2422
2423 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
2424
2425 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*
2426
2427 * MySQL: update test schema for MySQL 5 strict mode. #5861 *Tom Ward*
2428
2429 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2430
2431 * 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*
2432
2433 * 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*
2434
2435 # Create a tagging to associate the post and tag.
2436 post.tags << Tag.find_by_name('old')
2437 post.tags.create! :name => 'general'
2438
2439 # Would have been:
2440 post.taggings.create!(:tag => Tag.find_by_name('finally')
2441 transaction do
2442 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
2443 end
2444
2445 * Cache nil results for :included has_one associations also. #5787 *Michael Schoen*
2446
2447 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
2448
2449 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
2450 Example: Invoice::Lineitem is given table name invoice_lineitems
2451
2452 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2453 # people_active_last_name_index, people_active_deactivated_at_index
2454 add_index :people, [:active, :last_name]
2455 add_index :people, [:active, :deactivated_at]
2456 remove_index :people, [:active, :last_name]
2457 remove_index :people, [:active, :deactivated_at]
2458
2459 WARNING: backward-incompatibility. Multicolumn indexes created before this
2460 revision were named using the first column name only. Now they're uniquely
2461 named using all indexed columns.
2462
2463 To remove an old multicolumn index, remove_index :table_name, :first_column
2464
2465 * Fix for deep includes on the same association. *richcollins@gmail.com*
2466
2467 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
2468
2469 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
2470
2471 * 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*
2472
2473 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
2474
2475 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
2476
2477 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
2478
2479 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
2480
2481 * Formally deprecate the deprecated finders. *Michael Koziarski*
2482
2483 * Formally deprecate rich associations. *Michael Koziarski*
2484

2486
2487 * Fix announcement of very long migration names. #5722 *blake@near-time.com*
2488
2489 * The exists? class method should treat a string argument as an id rather than as conditions. #5698 *jeremy@planetargon.com*
2490
2491 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
2492
2493 * Added support for conditions on Base.exists? #5689 [Josh Peek]. Examples:
2494
2495 assert (Topic.exists?(:author_name => "David"))
2496 assert (Topic.exists?(:author_name => "Mary", :approved => true))
2497 assert (Topic.exists?(["parent_id = ?", 1]))
2498

2504
2505 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
2506
2507 * Allow #count through a has_many association to accept :include. *Dan Peterson*
2508
2509 * create_table rdoc: suggest :id => false for habtm join tables. *Zed Shaw*
2510
2511 * PostgreSQL: return array fields as strings. #4664 *Robby Russell*
2512
2513 * 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*
2514
2515 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2516
2517 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2518
2519 * 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*
2520
2521 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*
2522
2523 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2524
2525 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2526
2527 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2528
2529 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2530
2531 * 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*
2532
2533 * 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*
2534
2535 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2536
2537 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2538
2539 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2540
2541 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2542
2543 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2544

2546
2547 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2548
2549 * 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*
2550 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2551 Person.transaction do
2552 # select * from people where id=1 for update
2553 person = Person.find(1, :lock => true)
2554 person.visits += 1
2555 person.save!
2556 end
2557
2558 * 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*
2559
2560 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2561
2562 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2563
2564 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2565
2566 * 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*
2567
2568 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2569
2570 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2571
2572 ...is the same as:
2573 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2574
2575 This makes it easier to pass in the options from a form or otherwise outside.

2736 end
2737
2738 Post.find :all, :include => :tagging

2741
2742 * Added support for going through a polymorphic has_many association: (closes #4401) *Rick Olson*
2743

2746 belongs_to :firm
2747 end
2748
2749 class Firm < ActiveRecord::Base
2750 has_many :photo_collections
2751 has_many :photos, :through => :photo_collections
2752 end
2753
2754 * Multiple fixes and optimizations in PostgreSQL adapter, allowing ruby-postgres gem to work properly. *ruben.nine@gmail.com*
2755

2767
2768 * Fixed broken OCIAdapter #4457 *Michael Schoen*
2769
2770
2771 ## 1.14.0 (March 27th, 2006) ##
2772
2773 * Replace 'rescue Object' with a finer grained rescue. Closes #4431. *Nicholas Seckar*
2774
2775 * Fixed eager loading so that an aliased table cannot clash with a has_and_belongs_to_many join table *Rick Olson*
2776
2777 * Add support for :include to with_scope *andrew@redlinesoftware.com*
2778

2782
2783 * Changed has_and_belongs_to_many join to INNER JOIN for Mysql 3.23.x. Closes #4348 *Rick Olson*
2784
2785 * Fixed issue that kept :select options from being scoped *Rick Olson*
2786
2787 * Fixed db_schema_import when binary types are present #3101 *David Heinemeier Hansson*
2788
2789 * Fixed that MySQL enums should always be returned as strings #3501 *David Heinemeier Hansson*
2790

2792
2793 class Connection < ActiveRecord::Base
2794 belongs_to :user
2795 belongs_to :channel
2796 end
2797
2798 class Channel < ActiveRecord::Base
2799 has_many :connections
2800 has_many :contacts, :through => :connections, :class_name => 'User' # OLD
2801 has_many :contacts, :through => :connections, :source => :user # NEW
2802 end
2803
2804 * 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*
2805
2806 * Allow overriding of find parameters in scoped has_many :through calls *Rick Olson*
2807
2808 In this example, :include => false disables the default eager association from loading. :select changes the standard
2809 select clause. :joins specifies a join that is added to the end of the has_many :through query.
2810
2811 class Post < ActiveRecord::Base
2812 has_many :tags, :through => :taggings, :include => :tagging do
2813 def add_joins_and_select
2814 find :all, :select => 'tags.*, authors.id as author_id', :include => false,
2815 :joins => 'left outer join posts on taggings.taggable_id = posts.id left outer join authors on posts.author_id = authors.id'
2816 end
2817 end
2818 end
2819
2820 * 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*
2821
2822 * Don't classify the has_one class when eager loading, it is already singular. Add tests. (closes #4117) *Jonathan Viney*
2823
2824 * Quit ignoring default :include options in has_many :through calls *Mark James*
2825
2826 * Allow has_many :through associations to find the source association by setting a custom class (closes #4307) *Jonathan Viney*
2827
2828 * Eager Loading support added for has_many :through => :has_many associations (see below). *Rick Olson*
2829
2830 * Allow has_many :through to work on has_many associations (closes #3864) [sco@scottraymond.net] Example:
2831
2832 class Firm < ActiveRecord::Base
2833 has_many :clients
2834 has_many :invoices, :through => :clients
2835 end
2836
2837 class Client < ActiveRecord::Base
2838 belongs_to :firm
2839 has_many :invoices
2840 end
2841
2842 class Invoice < ActiveRecord::Base
2843 belongs_to :client
2844 end
2845
2846 * Raise error when trying to select many polymorphic objects with has_many :through or :include (closes #4226) *Josh Susser*
2847
2848 * Fixed has_many :through to include :conditions set on the :through association. closes #4020 *Jonathan Viney*
2849
2850 * 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*
2851
2852 * SQL Server adapter gets some love #4298 *Ryan Tomayko*
2853
2854 * 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*
2855
2856 * 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):
2857
2858 Author.find(:all, :include => { :posts => :special_comments }, :order => 'special_comments.body')
2859
2860 * Add AbstractAdapter#table_alias_for to create table aliases according to the rules of the current adapter. *Rick Olson*
2861
2862 * 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*
2863
2864 * Remove broken attempts at handling columns with a default of 'now()' in the postgresql adapter. #2257 *Michael Koziarski*
2865
2866 * 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*
2867
2868 * Fixed that Migration#execute would have the table name prefix appended to its query #4110 *mark.imbriaco@pobox.com*
2869
2870 * Make all tinyint(1) variants act like boolean in mysql (tinyint(1) unsigned, etc.) *Jamis Buck*
2871
2872 * Use association's :conditions when eager loading. [Jeremy Evans] #4144
2873
2874 * Alias the has_and_belongs_to_many join table on eager includes. #4106 *Jeremy Evans*
2875
2876 This statement would normally error because the projects_developers table is joined twice, and therefore joined_on would be ambiguous.
2877
2878
