959fb8ea »
2012-06-07 Revert "Perf: Don't load the association for #delete_all."
96 * Revert earlier 'perf fix' (see 3.2.4 changelog / GH #6289). This
97 change introduced a regression (GH #6609). assoc.clear and
98 assoc.delete_all have loaded the association before doing the delete
99 since at least Rails 2.3. Doing the delete without loading the
100 records means that the `before_remove` and `after_remove` callbacks do
101 not get invoked. Therefore, this change was less a fix a more an
102 optimisation, which should only have gone into master.

276 `MyModel::GeneratedFeatureMethods`. It is included into the model class immediately after
277 the `generated_attributes_methods` module defined in ActiveModel, so association methods
278 override attribute methods of the same name. *Josh Susser*

331
332 * Add first_or_create, first_or_create!, first_or_initialize methods to Active Record. This is a
333 better approach over the old find_or_create_by dynamic methods because it's clearer which

387 * Fix bug where building the conditions of a nested through association could potentially
388 modify the conditions of the through and/or source association. If you have experienced
389 bugs with conditions appearing in the wrong queries when using nested through associations,
390 this probably solves your problems. *GH #3271*

412 ## Rails 3.1.1 (October 7, 2011) ##
413
414 * Add deprecation for the preload_associations method. Fixes #3022.
415
416 *Jon Leighton*
417
418 * Don't require a DB connection when loading a model that uses set_primary_key. GH #2807.
419
420 *Jon Leighton*
421
422 * Fix using select() with a habtm association, e.g. Person.friends.select(:name). GH #3030 and
423 \#2923.
424
425 *Hendy Tanata*
426
427 * Fix belongs_to polymorphic with custom primary key on target. GH #3104.
428
429 *Jon Leighton*
430
431 * CollectionProxy#replace should change the DB records rather than just mutating the array.
432 Fixes #3020.
433
434 *Jon Leighton*
435
436 * LRU cache in mysql and sqlite are now per-process caches.
437
438 * lib/active_record/connection_adapters/mysql_adapter.rb: LRU cache keys are per process id.
439 * lib/active_record/connection_adapters/sqlite_adapter.rb: ditto
440 *Aaron Patterson*
441
442 * Support bulk change_table in mysql2 adapter, as well as the mysql one. *Jon Leighton*
443
444 * If multiple parameters are sent representing a date, and some are blank, the
445 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]
446 * ActiveRecord::Base.establish_connection now takes a string that contains
447 a URI that specifies the connection configuration. For example:
448 ActiveRecord::Base.establish_connection 'postgres://localhost/foo'
449
450 * 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.
451
452 So if you were doing this and expecting the second argument to be nil:
453
454 User.find_by_username_and_group("sikachu")
455
456 You'll now get `ArgumentError: wrong number of arguments (1 for 2).` You'll then have to do this:
457
458 User.find_by_username_and_group("sikachu", nil)
459
460 *Prem Sichanugrist*
461
462
463 ## Rails 3.1.0 (August 30, 2011) ##
464
465 * Add a proxy_association method to association proxies, which can be called by association
466 extensions to access information about the association. This replaces proxy_owner etc with
467 proxy_association.owner.
468
469 *Jon Leighton*
470
471 * ActiveRecord::MacroReflection::AssociationReflection#build_record has a new method signature.
472
473 Before: def build_association(*options)
474 After: def build_association(*options, &block)
475
476 Users who are redefining this method to extend functionality should ensure that the block is
477 passed through to ActiveRecord::Base#new.
478
479 This change is necessary to fix https://github.com/rails/rails/issues/1842.
480
481 *Jon Leighton*
482
483 * AR#pluralize_table_names can be used to singularize/pluralize table name of an individual model:
484
485 class User < ActiveRecord::Base
486 self.pluralize_table_names = false
487 end
488
489 Previously this could only be set globally for all models through ActiveRecord::Base.pluralize_table_names. *Guillermo Iguaran*
490
491 * Add block setting of attributes to singular associations:
492
493 class User < ActiveRecord::Base
494 has_one :account
495 end
496
497 user.build_account{ |a| a.credit_limit => 100.0 }
498
499 The block is called after the instance has been initialized. *Andrew White*
500
501 * 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*
502
503 * CSV Fixtures are deprecated and support will be removed in Rails 3.2.0
504
505 * AR#new, AR#create, AR#create!, AR#update_attributes and AR#update_attributes! all accept a second hash as option that allows you
506 to specify which role to consider when assigning attributes. This is built on top of ActiveModel's
507 new mass assignment capabilities:
508
509 class Post < ActiveRecord::Base
510 attr_accessible :title
511 attr_accessible :title, :published_at, :as => :admin
512 end
513
514 Post.new(params[:post], :as => :admin)
515
516 assign_attributes() with similar API was also added and attributes=(params, guard) was deprecated.
517
518 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.
519
520 *Josh Kalderimis*
521
522 * default_scope can take a block, lambda, or any other object which responds to `call` for lazy
523 evaluation:
524
525 default_scope { ... }
526 default_scope lambda { ... }
527 default_scope method(:foo)
528
529 This feature was originally implemented by Tim Morgan, but was then removed in favour of
530 defining a 'default_scope' class method, but has now been added back in by Jon Leighton.
531 The relevant lighthouse ticket is #1812.
532
533 * Default scopes are now evaluated at the latest possible moment, to avoid problems where
534 scopes would be created which would implicitly contain the default scope, which would then
535 be impossible to get rid of via Model.unscoped.
536
537 Note that this means that if you are inspecting the internal structure of an
538 ActiveRecord::Relation, it will *not* contain the default scope, though the resulting
539 query will do. You can get a relation containing the default scope by calling
540 ActiveRecord#with_default_scope, though this is not part of the public API.
541
542 *Jon Leighton*
543
544 * If you wish to merge default scopes in special ways, it is recommended to define your default
545 scope as a class method and use the standard techniques for sharing code (inheritance, mixins,
546 etc.):
547
548 class Post < ActiveRecord::Base
549 def self.default_scope
550 where(:published => true).where(:hidden => false)
551 end
552 end
553
554 *Jon Leighton*
555
556 * PostgreSQL adapter only supports PostgreSQL version 8.2 and higher.
557
558 * ConnectionManagement middleware is changed to clean up the connection pool
559 after the rack body has been flushed.
560
561 * Added an update_column method on ActiveRecord. This new method updates a given attribute on an object, skipping validations and callbacks.
562 It is recommended to use #update_attribute unless you are sure you do not want to execute any callback, including the modification of
563 the updated_at column. It should not be called on new records.
564 Example:
565
566 User.first.update_column(:name, "sebastian") # => true
567
568 *Sebastian Martinez*
569
570 * Associations with a :through option can now use *any* association as the
571 through or source association, including other associations which have a
572 :through option and has_and_belongs_to_many associations
573
574 *Jon Leighton*
575
576 * The configuration for the current database connection is now accessible via
577 ActiveRecord::Base.connection_config. *fxn*
578
579 * limits and offsets are removed from COUNT queries unless both are supplied.
580 For example:
581
582 People.limit(1).count # => 'SELECT COUNT(*) FROM people'
583 People.offset(1).count # => 'SELECT COUNT(*) FROM people'
584 People.limit(1).offset(1).count # => 'SELECT COUNT(*) FROM people LIMIT 1 OFFSET 1'
585
586 *lighthouse #6262*
587
588 * ActiveRecord::Associations::AssociationProxy has been split. There is now an Association class
589 (and subclasses) which are responsible for operating on associations, and then a separate,
590 thin wrapper called CollectionProxy, which proxies collection associations.
591
592 This prevents namespace pollution, separates concerns, and will allow further refactorings.
593
594 Singular associations (has_one, belongs_to) no longer have a proxy at all. They simply return
595 the associated record or nil. This means that you should not use undocumented methods such
596 as bob.mother.create - use bob.create_mother instead.
597
598 *Jon Leighton*
599
600 * Make has_many :through associations work correctly when you build a record and then save it. This
601 requires you to set the :inverse_of option on the source reflection on the join model, like so:
602
603 class Post < ActiveRecord::Base
604 has_many :taggings
605 has_many :tags, :through => :taggings
606 end
607
608 class Tagging < ActiveRecord::Base
609 belongs_to :post
610 belongs_to :tag, :inverse_of => :tagging # :inverse_of must be set!
611 end
612
613 class Tag < ActiveRecord::Base
614 has_many :taggings
615 has_many :posts, :through => :taggings
616 end
617
618 post = Post.first
619 tag = post.tags.build :name => "ruby"
620 tag.save # will save a Taggable linking to the post
621
622 *Jon Leighton*
623
624 * Support the :dependent option on has_many :through associations. For historical and practical
625 reasons, :delete_all is the default deletion strategy employed by association.delete(*records),
626 despite the fact that the default strategy is :nullify for regular has_many. Also, this only
627 works at all if the source reflection is a belongs_to. For other situations, you should directly
628 modify the through association.
629
630 *Jon Leighton*
631
632 * Changed the behaviour of association.destroy for has_and_belongs_to_many and has_many :through.
633 From now on, 'destroy' or 'delete' on an association will be taken to mean 'get rid of the link',
634 not (necessarily) 'get rid of the associated records'.
635
636 Previously, has_and_belongs_to_many.destroy(*records) would destroy the records themselves. It
637 would not delete any records in the join table. Now, it deletes the records in the join table.
638
639 Previously, has_many_through.destroy(*records) would destroy the records themselves, and the
640 records in the join table. [Note: This has not always been the case; previous version of Rails
641 only deleted the records themselves.] Now, it destroys only the records in the join table.
642
643 Note that this change is backwards-incompatible to an extent, but there is unfortunately no
644 way to 'deprecate' it before changing it. The change is being made in order to have
645 consistency as to the meaning of 'destroy' or 'delete' across the different types of associations.
646
647 If you wish to destroy the records themselves, you can do records.association.each(&:destroy)
648
649 *Jon Leighton*
650
651 * 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*
652
653 Example:
654
655 change_table(:users, :bulk => true) do |t|
656 t.string :company_name
657 t.change :birthdate, :datetime
658 end
659
660 This will now result in:
661
662 ALTER TABLE `users` ADD COLUMN `company_name` varchar(255), CHANGE `updated_at` `updated_at` datetime DEFAULT NULL
663
664 * Removed support for accessing attributes on a has_and_belongs_to_many join table. This has been
665 documented as deprecated behaviour since April 2006. Please use has_many :through instead.
666 *Jon Leighton*
667
668 * Added a create_association! method for has_one and belongs_to associations. *Jon Leighton*
669
670 * Migration files generated from model and constructive migration generators
671 (for example, add_name_to_users) use the reversible migration's `change`
672 method instead of the ordinary `up` and `down` methods. *Prem Sichanugrist*
673
674 * Removed support for interpolating string SQL conditions on associations. Instead, you should
675 use a proc, like so:
676
677 Before:
678
679 has_many :things, :conditions => 'foo = #{bar}'
680
681 After:
682
683 has_many :things, :conditions => proc { "foo = #{bar}" }
684
685 Inside the proc, 'self' is the object which is the owner of the association, unless you are
686 eager loading the association, in which case 'self' is the class which the association is within.
687
688 You can have any "normal" conditions inside the proc, so the following will work too:
689
690 has_many :things, :conditions => proc { ["foo = ?", bar] }
691
692 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
693 'record' to get the record being inserted or deleted. This is now passed as an argument to
694 the proc.
695
696 * Added ActiveRecord::Base#has_secure_password (via ActiveModel::SecurePassword) to encapsulate dead-simple password usage with BCrypt encryption and salting [DHH]. Example:
697
698 # Schema: User(name:string, password_digest:string, password_salt:string)
699 class User < ActiveRecord::Base
700 has_secure_password
701 end
702
703 user = User.new(:name => "david", :password => "", :password_confirmation => "nomatch")
704 user.save # => false, password required
705 user.password = "mUc3m00RsqyRe"
706 user.save # => false, confirmation doesn't match
707 user.password_confirmation = "mUc3m00RsqyRe"
708 user.save # => true
709 user.authenticate("notright") # => false
710 user.authenticate("mUc3m00RsqyRe") # => user
711 User.find_by_name("david").try(:authenticate, "notright") # => nil
712 User.find_by_name("david").try(:authenticate, "mUc3m00RsqyRe") # => user
713
714
715 * When a model is generated add_index is added by default for belongs_to or references columns
716
717 rails g model post user:belongs_to will generate the following:
718
719 class CreatePosts < ActiveRecord::Migration
720 def up
721 create_table :posts do |t|
722 t.belongs_to :user
723 t.timestamps
724 end
725
726 add_index :posts, :user_id
727 end
728
729 def down
730 drop_table :posts
731 end
732 end
733
734 *Santiago Pastorino*
735
736 * Setting the id of a belongs_to object will update the reference to the
737 object. [#2989 state:resolved]
738 * ActiveRecord::Base#dup and ActiveRecord::Base#clone semantics have changed
739 to closer match normal Ruby dup and clone semantics.
740 * Calling ActiveRecord::Base#clone will result in a shallow copy of the record,
741 including copying the frozen state. No callbacks will be called.
742 * Calling ActiveRecord::Base#dup will duplicate the record, including calling
743 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.
744 * Migrations can be defined as reversible, meaning that the migration system
745 will figure out how to reverse your migration. To use reversible migrations, just define the "change" method. For example:
746 class MyMigration < ActiveRecord::Migration
747 def change
748 create_table(:horses) do
749 t.column :content, :text
750 t.column :remind_at, :datetime
751 end
752 end
753 end
754
755 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.
756 * Migrations should use instance methods rather than class methods:
757 class FooMigration < ActiveRecord::Migration
758 def up
759 ...
760 end
761 end
762
763 *Aaron Patterson*
764
765 * has_one maintains the association with separate after_create/after_update instead
766 of a single after_save. *fxn*
767
768 * The following code:
769
770 Model.limit(10).scoping { Model.count }
771
772 now generates the following SQL:
773
774 SELECT COUNT(*) FROM models LIMIT 10
775
776 This may not return what you want. Instead, you may with to do something
777 like this:
778
779 Model.limit(10).scoping { Model.all.size }
780
781 *Aaron Patterson*

784 ## Rails 3.0.7 (April 18, 2011) ##
785
786 * Destroying records via nested attributes works independent of reject_if LH #6006 *Durran Jordan*
787
788 * Delegate any? and many? to Model.scoped for consistency *Andrew White*
789
790 * Quote the ORDER BY clause in batched finds - fixes #6620 *Andrew White*
791
792 * Change exists? so records are not instantiated - fixes #6127. This prevents after_find
793 and after_initialize callbacks being triggered when checking for record existence.
794 *Andrew White*
795
796 * Fix performance bug with attribute accessors which only occurred on Ruby 1.8.7, and ensure we
797 cache type-casted values when the column returned from the db contains non-standard chars.
798 *Jon Leighton*
799
800 * Fix a performance regression introduced here 86acbf1cc050c8fa8c74a10c735e467fb6fd7df8
801 related to read_attribute method *Stian Grytøyr*
802
803
804 ## Rails 3.0.6 (April 5, 2011) ##
805
806 * Un-deprecate reorder method *Sebastian Martinez*
807
808 * Extensions are applied when calling +except+ or +only+ on relations.
809 Thanks to Iain Hecker.
810
811 * Schemas set in set_table_name are respected by the mysql adapter. LH #5322
812
813 * Fixed a bug when empty? was called on a grouped Relation that wasn't loaded.
814 LH #5829
815
816 * Reapply extensions when using except and only. Thanks Iain Hecker.
817
818 * Binary data is escaped when being inserted to SQLite3 Databases. Thanks
819 Naruse!
820
821
822 ## Rails 3.0.5 (February 26, 2011) ##
823
824 * Model.where(:column => 1).where(:column => 2) will always produce an AND
825 query.
826 *Aaron Patterson*
827
828 * Deprecated support for interpolated association conditions in the form of :conditions => 'foo = #{bar}'.
829
830 Instead, you should use a proc, like so:
831
832 Before:
833
834 has_many :things, :conditions => 'foo = #{bar}'
835
836 After:
837
838 has_many :things, :conditions => proc { "foo = #{bar}" }
839
840 Inside the proc, 'self' is the object which is the owner of the association, unless you are
841 eager loading the association, in which case 'self' is the class which the association is within.
842
843 You can have any "normal" conditions inside the proc, so the following will work too:
844
845 has_many :things, :conditions => proc { ["foo = ?", bar] }
846
847 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
848 'record' to get the record being inserted or deleted. This is now passed as an argument to
849 the proc.
850
851 *Jon Leighton*
852
853
854 ## Rails 3.0.4 (February 8, 2011) ##
855
856 * Added deprecation warning for has_and_belongs_to_many associations where the join table has
857 additional attributes other than the keys. Access to these attributes is removed in 3.1.
858 Please use has_many :through instead. *Jon Leighton*
859
860
861 ## Rails 3.0.3 (November 16, 2010) ##
862
863 * Support find by class like this: Post.where(:name => Post)
864
865
866 ## Rails 3.0.2 (November 15, 2010) ##
867
868 * Dramatic speed increase (see: http://engineering.attinteractive.com/2010/10/arel-two-point-ohhhhh-yaaaaaa/) *Aaron Patterson*
869
870 * reorder is deprecated in favor of except(:order).order(...) *Santiago Pastorino*
871
872 * except is now AR public API
873
874 Model.order('name').except(:order).order('salary')
875
876 generates:
877
878 SELECT * FROM models ORDER BY salary
879
880 *Santiago Pastorino*
881
882 * The following code:
883
884 Model.limit(10).scoping { Model.count }
885
886 now generates the following SQL:
887
888 SELECT COUNT(*) FROM models LIMIT 10
889
890 This may not return what you want. Instead, you may with to do something
891 like this:
892
893 Model.limit(10).scoping { Model.all.size }
894
895 *Aaron Patterson*
896
897
898 ## Rails 3.0.1 (October 15, 2010) ##
899
900 * Introduce a fix for CVE-2010-3993
901
902
903 ## Rails 3.0.0 (August 29, 2010) ##
904
905 * Changed update_attribute to not run callbacks and update the record directly in the database *Neeraj Singh*
906
907 * Add scoping and unscoped as the syntax to replace the old with_scope and with_exclusive_scope *José Valim*
908
909 * New rake task, db:migrate:status, displays status of migrations #4947 *Kevin Skoglund*
910
911 * select and order for ActiveRecord now always concatenate nested calls. Use reorder if you want the original order to be overwritten *Santiago Pastorino*
912
913 * PostgreSQL: ensure the database time zone matches Ruby's time zone #4895 *Aaron Patterson*
914
915 * Fixed that ActiveRecord::Base.compute_type would swallow NoMethodError #4751 *Andrew Bloomgarden, Andrew White*
916
917 * Add index length support for MySQL. #1852 *Emili Parreno, Pratik Naik*
918
919 Example:
920
921 add_index(:accounts, :name, :name => 'by_name', :length => 10)
922 => CREATE INDEX by_name ON accounts(name(10))
923
924 add_index(:accounts, [:name, :surname], :name => 'by_name_surname', :length => {:name => 10, :surname => 15})
925 => CREATE INDEX by_name_surname ON accounts(name(10), surname(15))
926
927 * find_or_create_by_attr(value, ...) works when attr is protected. #4457 *Santiago Pastorino, Marc-André Lafortune*
928
929 * New callbacks: after_commit and after_rollback. Do expensive operations like image thumbnailing after_commit instead of after_save. #2991 *Brian Durand*
930
931 * 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*
932
933 * 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*

944 def posts_count
945 Post.count(:user_id => to_a.map(&:id))
946 end
947 end
948
949 * To prefix the table names of all models in a module, define self.table_name_prefix on the module. #4032 *Andrew White*
950
951 * 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*
952
953 * 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*
954
955 * Allow relations to be used as scope.
956
957 class Item
958 scope :red, where(:colour => 'red')
959 end
960
961 Item.red.limit(10) # Ten red items
962

978 Developer.group("salary").having("sum(salary) > 10000").select("salary")
979
980 * Add Relation#count. *Pratik Naik*
981
982 legends = People.where("age > 100")
983 legends.count
984 legends.count(:age, :distinct => true)
985 legends.select('id').count
986
987 * Add Model.readonly and association_collection#readonly finder method. *Pratik Naik*
988
989 Post.readonly.to_a # Load all posts in readonly mode
990 @user.items.readonly(false).to_a # Load all the user items in writable mode
991
992 * Add .lock finder method *Pratik Naik*
993
994 User.lock.where(:name => 'lifo').to_a
995

1014
1015 * Add find(ids) to relations. *Pratik Naik*
1016
1017 old_users = User.order("age DESC")
1018 old_users.find(1)
1019 old_users.find(1, 2, 3)
1020
1021 * Add new finder methods to association collection. *Pratik Naik*
1022
1023 class User < ActiveRecord::Base
1024 has_many :items
1025 end
1026
1027 user = User.first
1028 user.items.where(:items => {:colour => 'red'})

1030
1031 * Add relation.reload to force reloading the records. *Pratik Naik*
1032
1033 topics = Topic.scoped
1034 topics.to_a # force load
1035 topics.first # returns a cached record
1036 topics.reload
1037 topics.first # Fetches a new record from the database
1038
1039 * Rename Model.conditions and relation.conditions to .where. *Pratik Naik*
1040
1041 Before :
1042 User.conditions(:name => 'lifo')
1043 User.select('id').conditions(["age > ?", 21])
1044

1054 posts.each {|p| puts p.id } # Fires "select id from posts order by name"
1055
1056 * Model.scoped now returns a relation if invoked without any arguments. *Pratik Naik*
1057
1058 Example :
1059
1060 posts = Post.scoped
1061 posts.size # Fires "select count(*) from posts" and returns the count
1062 posts.each {|p| puts p.name } # Fires "select * from posts" and loads post objects
1063
1064 * Association inverses for belongs_to, has_one, and has_many. Optimization to reduce database queries. #3533 *Murray Steele*
1065
1066 # post.comments sets each comment's post without needing to :include
1067 class Post < ActiveRecord::Base
1068 has_many :comments, :inverse_of => :post
1069 end
1070
1071 * MySQL: add_ and change_column support positioning. #3286 *Ben Marini*

1076
1077 * PostgreSQL: XML datatype support. #1874 *Leonardo Borges*
1078
1079 * 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*
1080
1081 * SQLite: drop support for 'dbfile' option in favor of 'database.' #2363 *Paul Hinze, Jeremy Kemper*
1082
1083 * Added :primary_key option to belongs_to associations. #765 *Szymon Nowak, Philip Hallstrom, Noel Rocha*
1084 # employees.company_name references companies.name
1085 Employee.belongs_to :company, :primary_key => 'name', :foreign_key => 'company_name'
1086
1087 * Implement #many? for NamedScope and AssociationCollection using #size. #1500 *Chris Kampmeier*

1124
1125 class Person < ActiveRecord::Base
1126 default_scope :order => 'last_name, first_name'
1127 end
1128
1129 class Company < ActiveRecord::Base
1130 has_many :people
1131 end
1132

1155
1156 * Added find_last_by dynamic finder #762 *Emilio Tagua*
1157
1158 * Internal API: configurable association options and build_association method for reflections so plugins may extend and override. #985 *Hongli Lai (Phusion)*

1180
1181 * Allow conditions on multiple tables to be specified using hash. [Pratik Naik]. Example:
1182
1183 User.all :joins => :items, :conditions => { :age => 10, :items => { :color => 'black' } }
1184 Item.first :conditions => { :items => { :color => 'red' } }
1185
1186 * Always treat integer :limit as byte length. #420 *Tarmo Tänav*

1263
1264 Post.find(1).to_json # => {"title": ...}
1265 config.active_record.include_root_in_json = true
1266 Post.find(1).to_json # => {"post": {"title": ...}}

1270 * PostgreSQL: create_ and drop_database support. #9042 *ez, pedz, Nick Sieger*
1271
1272 * Ensure that validates_uniqueness_of works with with_scope. Closes #9235. *Nik Wakelin, cavalle*
1273
1274 * Partial updates include only unsaved attributes. Off by default; set YourClass.partial_updates = true to enable. *Jeremy Kemper*

1279
1280 * Track changes to unsaved attributes. *Jeremy Kemper*
1281

Also added rake db:migrate:up/down to apply individual migrations that may need to be run when you merge branches #11458 *John Barnette*
1283
1284 * Fixed that has_many :through would ignore the hash conditions #11447 *Emilio Tagua*
1285
1286 * Fix issue where the :uniq option of a has_many :through association is ignored when find(:all) is called. Closes #9407 *cavalle*
1287
1288 * Fix duplicate table alias error when including an association with a has_many :through association on the same join table. Closes #7310 *cavalle*

1573 belongs_to :article, :counter_cache => :comments_count
1574 end
1575
1576 class Article < ActiveRecord::Base

1602
1603 * Define dynamic finders as real methods after first usage. *bscofield*

1615 * Extract Firebird, FrontBase, and OpenBase adapters into gems. #9508, #9509, #9510 *Jeremy Kemper*
1616

1641 For more information see: http://dev.rubyonrails.org/ticket/8049
1642
1643 * Don't clobber includes passed to has_many.count *Jack Danger Canty*
1644
1645 * Make sure has_many uses :include when counting *Jack Danger Canty*
1646
1647 * Change the implementation of ActiveRecord's attribute reader and writer methods *Michael Koziarski*
1648 - 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.
1649 * Perform a deep #dup on query cache results so that modifying activerecord attributes does not modify the cached attributes. *Rick Olson*

1657
1658 validates_presence_of :identity_url, :if => using_open_id?
1659 validates_presence_of :username, :unless => using_open_id?
1660 validates_presence_of :password, :unless => using_open_id?

1664 * Fix and properly document/test count(column_name) usage. Closes #8999 *Pratik Naik*
1665
1666 * Remove deprecated count(conditions=nil, joins=nil) usage. Closes #8993 *Pratik Naik*
1667
1668 * Change belongs_to so that the foreign_key assumption is taken from the association name, not the class name. Closes #8992 *Josh Susser*
1669
1670 OLD
1671 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is user_id
1672
1673 NEW
1674 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is visitor_id
1675
1676 * Remove spurious tests from deprecated_associations_test, most of these aren't deprecated, and are duplicated in associations_test. Closes #8987 *Pratik Naik*
1677
1678 * Make create! on a has_many :through association return the association object. Not the collection. Closes #8786 *Pratik Naik*
1679

1687
1688 * Fix polymorphic has_one associations declared in an abstract class. #8638 *Pratik Naik, Dax Huiberts*
1689
1690 * Fixed validates_associated should not stop on the first error. #4276 *mrj, Manfred Stienstra, Josh Peek*

1713
1714 * Raise an exception if both attr_protected and attr_accessible are declared. #8507 *stellsmi*
1715
1716 * SQLite, MySQL, PostgreSQL, Oracle: quote column names in column migration SQL statements. #8466 *marclove, lorenjohnson*
1717
1718 * Allow nil serialized attributes with a set class constraint. #7293 *sandofsky*
1719
1720 * Oracle: support binary fixtures. #7987 *Michael Schoen*
1721
1722 * Fixtures: pull fixture insertion into the database adapters. #7987 *Michael Schoen*

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*
1739
1740 * Ensure that associations with :dependent => :delete_all respect :conditions option. Closes #8034 *Jack Danger Canty, Josh Peek, Rick Olson*

1760 * Add documentation caveat about when to use count_by_sql. *fearoffish*
1761
1762 * Enhance documentation for increment_counter and decrement_counter. *fearoffish*
1763
1764 * Provide brief introduction to what optimistic locking is. *fearoffish*
1765
1766 * Add documentation for :encoding option to mysql adapter. *marclove*
1767
1768 * Added short-hand declaration style to migrations (inspiration from Sexy Migrations, http://errtheblog.com/post/2381) [David Heinemeier Hansson]. Example:
1769
1770 create_table "products" do |t|
1771 t.column "shop_id", :integer
1772 t.column "creator_id", :integer
1773 t.column "name", :string, :default => "Untitled"
1774 t.column "value", :string, :default => "Untitled"
1775 t.column "created_at", :datetime
1776 t.column "updated_at", :datetime
1777 end
1778
1779 ...can now be written as:
1780
1781 create_table :products do |t|
1782 t.integer :shop_id, :creator_id
1783 t.string :name, :value, :default => "Untitled"
1784 t.timestamps
1785 end
1786
1787 * 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*
1788
1789 * Improve performance of calling .create on has_many :through associations. *evan*
1790
1791 * Improved cloning performance by relying less on exception raising #8159 *Blaine*
1792
1793 * Added ActiveRecord::Base.inspect to return a column-view like #<Post id:integer, title:string, body:text> *David Heinemeier Hansson*
1794
1795 * Added yielding of Builder instance for ActiveRecord::Base#to_xml calls *David Heinemeier Hansson*
1796
1797 * Small additions and fixes for ActiveRecord documentation. Closes #7342 *Jeremy McAnally*
1798
1799 * Add helpful debugging info to the ActiveRecord::StatementInvalid exception in ActiveRecord::ConnectionAdapters::SqliteAdapter#table_structure. Closes #7925. *court3nay*
1800
1801 * SQLite: binary escaping works with $KCODE='u'. #7862 *tsuka*
1802
1803 * Base#to_xml supports serialized attributes. #7502 *jonathan*
1804
1805 * Base.update_all :order and :limit options. Useful for MySQL updates that must be ordered to avoid violating unique constraints. *Jeremy Kemper*
1806
1807 * 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*
1808
1809 * 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*
1810
1811 * 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*
1812
1813 * 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*
1814
1815 * Allow a polymorphic :source for has_many :through associations. Closes #7143 *protocool*
1816
1817 * Consistent public/protected/private visibility for chained methods. #7813 *Dan Manges*
1818
1819 * Oracle: fix quoted primary keys and datetime overflow. #7798 *Michael Schoen*
1820
1821 * Consistently quote primary key column names. #7763 *toolmantim*
1822
1823 * Fixtures: fix YAML ordered map support. #2665 *Manuel Holtgrewe, nfbuckley*
1824
1825 * DateTimes assume the default timezone. #7764 *Geoff Buesing*
1826
1827 * Sybase: hide timestamp columns since they're inherently read-only. #7716 *Mike Joyce*
1828
1829 * Oracle: overflow Time to DateTime. #7718 *Michael Schoen*
1830
1831 * PostgreSQL: don't use async_exec and async_query with postgres-pr. #7727, #7762 *flowdelic, toolmantim*
1832
1833 * Fix has_many :through << with custom foreign keys. #6466, #7153 *naffis, Rich Collins*
1834
1835 * Test DateTime native type in migrations, including an edge case with dates
1836 during calendar reform. #7649, #7724 [fedot, Geoff Buesing]
1837 * SQLServer: correctly schema-dump tables with no indexes or descending indexes. #7333, #7703 *Jakob Skjerning, Tom Ward*
1838
1839 * SQLServer: recognize real column type as Ruby float. #7057 *sethladd, Tom Ward*
1840
1841 * Added fixtures :all as a way of loading all fixtures in the fixture directory at once #7214 *Manfred Stienstra*
1842
1843 * Added database connection as a yield parameter to ActiveRecord::Base.transaction so you can manually rollback [David Heinemeier Hansson]. Example:
1844
1845 transaction do |transaction|
1846 david.withdrawal(100)
1847 mary.deposit(100)
1848 transaction.rollback! # rolls back the transaction that was otherwise going to be successful
1849 end
1850
1851 * Made increment_counter/decrement_counter play nicely with optimistic locking, and added a more general update_counters method *Jamis Buck*
1852
1853 * 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*
1854 Task.cache { Task.find(1); Task.find(1) } # => 1 query
1855
1856 * 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*
1857
1858 * Oracle: fix lob and text default handling. #7344 *gfriedrich, Michael Schoen*
1859
1860 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
1861
1862 * MySQL: blob and text columns may not have defaults in 5.x. Update fixtures schema for strict mode. #6695 *Dan Kubb*
1863
1864 * 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*
1865
1866 * MySQL: SET SQL_AUTO_IS_NULL=0 so 'where id is null' doesn't select the last inserted id. #6778 *Jonathan Viney, timc*
1867
1868 * Use Date#to_s(:db) for quoted dates. #7411 *Michael Schoen*
1869
1870 * Don't create instance writer methods for class attributes. Closes #7401 *Rick Olson*
1871
1872 * Docs: validations examples. #7343 *zackchandler*
1873
1874 * Add missing tests ensuring callbacks work with class inheritance. Closes #7339 *sandofsky*
1875
1876 * Fixtures use the table name and connection from set_fixture_class. #7330 *Anthony Eden*
1877
1878 * Remove useless code in #attribute_present? since 0 != blank?. Closes #7249 *Josh Susser*
1879
1880 * Fix minor doc typos. Closes #7157 *Josh Susser*
1881
1882 * Fix incorrect usage of #classify when creating the eager loading join statement. Closes #7044 *Josh Susser*
1883
1884 * SQLServer: quote table name in indexes query. #2928 *keithm@infused.org*
1885
1886 * Subclasses of an abstract class work with single-table inheritance. #5704, #7284 *BertG, nick+rails@ag.arizona.edu*
1887
1888 * Make sure sqlite3 driver closes open connections on disconnect *Rob Rasmussen*
1889
1890 * [DOC] clear up some ambiguity with the way has_and_belongs_to_many creates the default join table name. #7072 *Jeremy McAnally*
1891
1892 * change_column accepts :default => nil. Skip column options for primary keys. #6956, #7048 *Dan Manges, Jeremy Kemper*
1893
1894 * 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*
1895
1896 * Oracle: create_table takes a :sequence_name option to override the 'tablename_seq' default. #7000 *Michael Schoen*
1897
1898 * MySQL: retain SSL settings on reconnect. #6976 *randyv2*
1899
1900 * Apply scoping during initialize instead of create. Fixes setting of foreign key when using find_or_initialize_by with scoping. *Cody Fauser*
1901
1902 * SQLServer: handle [quoted] table names. #6635 *rrich*
1903
1904 * acts_as_nested_set works with single-table inheritance. #6030 *Josh Susser*
1905
1906 * PostgreSQL, Oracle: correctly perform eager finds with :limit and :order. #4668, #7021 *eventualbuddha, Michael Schoen*
1907
1908 * Pass a range in :conditions to use the SQL BETWEEN operator. #6974 *Dan Manges*
1909 Student.find(:all, :conditions => { :grade => 9..12 })
1910
1911 * Fix the Oracle adapter for serialized attributes stored in CLOBs. Closes #6825 *mschoen, tdfowler*
1912
1913 * [DOCS] Apply more documentation for ActiveRecord Reflection. Closes #4055 *Robby Russell*
1914
1915 * [DOCS] Document :allow_nil option of #validate_uniqueness_of. Closes #3143 *Caio Chassot*
1916
1917 * Bring the sybase adapter up to scratch for 1.2 release. *jsheets*
1918
1919 * Rollback new_record? and id when an exception is raised in a save callback. #6910 *Ben Curren, outerim*
1920
1921 * Pushing a record on an association collection doesn't unnecessarily load all the associated records. *Obie Fernandez, Jeremy Kemper*
1922
1923 * Oracle: fix connection reset failure. #6846 *leonlleslie*
1924
1925 * Subclass instantiation doesn't try to explicitly require the corresponding subclass. #6840 *leei, Jeremy Kemper*
1926
1927 * 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*
1928
1929 * 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*
1930
1931 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
1932
1933 * Add AssociationCollection#create! to be consistent with AssociationCollection#create when dealing with a foreign key that is a protected attribute *Cody Fauser*
1934
1935 * 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*
1936
1937 * Change fixture_path to a class inheritable accessor allowing test cases to have their own custom set of fixtures. #6672 *Zach Dennis*
1938
1939 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
1940
1941 * Simplify query_attribute by typecasting the attribute value and checking whether it's nil, false, zero or blank. #6659 *Jonathan Viney*
1942
1943 * 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*
1944
1945 * Run validations in the order they were declared. #6657 *obrie*
1946
1947 * 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*
1948
1949 * Simplify association proxy implementation by factoring construct_scope out of method_missing. #6643 *martin*
1950
1951 * Oracle: automatically detect the primary key. #6594 *vesaria, Michael Schoen*
1952
1953 * 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*
1954
1955 * Don't inspect unloaded associations. #2905 *lmarlow*
1956
1957 * SQLite: use AUTOINCREMENT primary key in >= 3.1.0. #6588, #6616 *careo, lukfugl*
1958
1959 * Cache inheritance_column. #6592 *Stefan Kaes*
1960
1961 * Firebird: decimal/numeric support. #6408 *macrnic*
1962
1963 * make add_order a tad faster. #6567 *Stefan Kaes*
1964
1965 * Find with :include respects scoped :order. #5850
1966
1967 * Support nil and Array in :conditions => { attr => value } hashes. #6548 *Assaf, Jeremy Kemper*
1968 find(:all, :conditions => { :topic_id => [1, 2, 3], :last_read => nil }
1969
1970 * 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*
1971
1972 * SQLite: fix calculations workaround, remove count(distinct) query rewrite, cleanup test connection scripts. *Jeremy Kemper*
1973
1974 * SQLite: count(distinct) queries supported in >= 3.2.6. #6544 *Bob Silva*
1975
1976 * Dynamically generate reader methods for serialized attributes. #6362 *Stefan Kaes*
1977
1978 * Deprecation: object transactions warning. *Jeremy Kemper*
1979
1980 * has_one :dependent => :nullify ignores nil associates. #4848, #6528 *bellis@deepthought.org, janovetz, Jeremy Kemper*
1981
1982 * 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*
1983
1984 * Make add_column use the options hash with the Sqlite Adapter. Closes #6464 *obrie*
1985
1986 * Document other options available to migration's add_column. #6419 *grg*
1987
1988 * MySQL: all_hashes compatibility with old MysqlRes class. #6429, #6601 *Jeremy Kemper*
1989
1990 * Fix has_many :through to add the appropriate conditions when going through an association using STI. Closes #5783. *Jonathan Viney*
1991
1992 * fix select_limited_ids_list issues in postgresql, retain current behavior in other adapters *Rick Olson*
1993
1994 * Restore eager condition interpolation, document it's differences *Rick Olson*

1997
1998 * Add #delete support to has_many :through associations. Closes #6049 *Martin Landers*
1999
2000 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
2001
2002 * 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*
2003
2004 * 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*
2005
2006 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*
2007
2008 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
2009
2010 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
2011
2012 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
2013
2014 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
2015
2016 * 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*
2017
2018 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
2019
2020 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*
2021
2022 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*

2029
2030 * Mock Time.now for more accurate Touch mixin tests. #6213 *Dan Peterson*
2031
2032 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
2033
2034 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
2035
2036 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
2037
2038 * 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*
2039
2040 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
2041
2042 * Document validates_presences_of behavior with booleans: you probably want validates_inclusion_of :attr, :in => [true, false]. #2253 *Bob Silva*
2043
2044 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
2045
2046 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
2047
2048 * Deprecation: update docs. #5998 *Jakob Skjerning, Kevin Clark*
2049
2050 * Add some XmlSerialization tests for ActiveRecord *Rick Olson*
2051
2052 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
2053
2054 * Tighten rescue clauses. #5985 *james@grayproductions.net*
2055
2056 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
2057
2058 * 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*
2059
2060 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
2061
2062 * 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*
2063
2064 * SQLServer: fix eager association test. #5901 *Tom Ward*
2065
2066 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
2067
2068 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
2069
2070 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*
2071
2072 * MySQL: update test schema for MySQL 5 strict mode. #5861 *Tom Ward*
2073
2074 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2075
2076 * 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*
2077
2078 * 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*
2079
2080 # Create a tagging to associate the post and tag.
2081 post.tags << Tag.find_by_name('old')
2082 post.tags.create! :name => 'general'
2083
2084 # Would have been:
2085 post.taggings.create!(:tag => Tag.find_by_name('finally')
2086 transaction do
2087 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
2088 end
2089
2090 * Cache nil results for :included has_one associations also. #5787 *Michael Schoen*
2091
2092 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
2093
2094 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
2095 Example: Invoice::Lineitem is given table name invoice_lineitems
2096
2097 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2098 # people_active_last_name_index, people_active_deactivated_at_index
2099 add_index :people, [:active, :last_name]
2100 add_index :people, [:active, :deactivated_at]
2101 remove_index :people, [:active, :last_name]
2102 remove_index :people, [:active, :deactivated_at]
2103
2104 WARNING: backward-incompatibility. Multicolumn indexes created before this
2105 revision were named using the first column name only. Now they're uniquely
2106 named using all indexed columns.
2107
2108 To remove an old multicolumn index, remove_index :table_name, :first_column
2109
2110 * Fix for deep includes on the same association. *richcollins@gmail.com*
2111
2112 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
2113
2114 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
2115
2116 * Document find's :from option. Closes #5762. *andrew@redlinesoftware.com*
2117
2118 * 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*
2119
2120 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
2121
2122 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
2123
2124 * Add documentation for how to disable timestamps on a per model basis. Closes #5684. *matt@mattmargolis.net Marcel Molina Jr.*
2125
2126 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
2127
2128 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
2129
2130 * Formally deprecate the deprecated finders. *Michael Koziarski*
2131

2135
2136 * Fix announcement of very long migration names. #5722 *blake@near-time.com*
2137
2138 * The exists? class method should treat a string argument as an id rather than as conditions. #5698 *jeremy@planetargon.com*
2139
2140 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
2141
2142 * Added support for conditions on Base.exists? #5689 [Josh Peek]. Examples:
2143
2144 assert (Topic.exists?(:author_name => "David"))
2145 assert (Topic.exists?(:author_name => "Mary", :approved => true))

2161
2162 * 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*
2163
2164 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2165
2166 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2167
2168 * 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*
2169
2170 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*
2171
2172 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2173
2174 * Update callbacks documentation. #3970 *Robby Russell <robby@planetargon.com>*
2175
2176 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2177
2178 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2179
2180 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2181
2182 * 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*
2183
2184 * 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*
2185
2186 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2187
2188 * Minor tweak to improve performance of ActiveRecord::Base#to_param.
2189
2190 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2191
2192 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2193
2194 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2195
2196 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2197
2198 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2199
2200 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2201
2202 * 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*
2203 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2204 Person.transaction do
2205 # select * from people where id=1 for update
2206 person = Person.find(1, :lock => true)
2207 person.visits += 1
2208 person.save!
2209 end
2210
2211 * 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*
2212
2213 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*

2215 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2216
2217 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2218
2219 * 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*
2220
2221 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2222
2223 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2224
2225 ...is the same as:
2226 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2227
2228 This makes it easier to pass in the options from a form or otherwise outside.
2229

2240
2241 * 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*
2242
2243 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
2244
2245 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
2246
2247 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
2248 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
2249 Foo.find(:first, :conditions => ['bar_id = ?', bar])
2250
2251 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
2252
2253 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
2254
2255 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*

2270 * Fix Oracle boolean support and tests. Closes #5139. *Michael Schoen*
2271
2272 * 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*
2273
2274 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2275
2276 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2277
2278 * 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*

2374
2375 * Don't create instance writer methods for class attributes. *Rick Olson*
2376
2377 * 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*
2378
2379 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
2380
2381 * 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*
2382

2424
2425 * 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*
2426
2427 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
2428

2431
2432 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
2433
2434 * 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*
2435

2487
2488 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
