959fb8e @jonleighton Revert "Perf: Don't load the association for #delete_all."
jonleighton authored Jun 7, 2012
80 * Revert earlier 'perf fix' (see 3.2.4 changelog / GH #6289). This
81 change introduced a regression (GH #6609). assoc.clear and
82 assoc.delete_all have loaded the association before doing the delete
83 since at least Rails 2.3. Doing the delete without loading the
84 records means that the `before_remove` and `after_remove` callbacks do
85 not get invoked. Therefore, this change was less a fix a more an
86 optimisation, which should only have gone into master.

joshsusser authored Nov 27, 2011
258 * Generated association methods are created within a separate module to allow overriding and

260 `MyModel::GeneratedFeatureMethods`. It is included into the model class immediately after
261 the `generated_attributes_methods` module defined in ActiveModel, so association methods

281272a @jonleighton Convert CHANGELOGs to Markdown format.
jonleighton authored Nov 4, 2011
371 * Fix bug where building the conditions of a nested through association could potentially
372 modify the conditions of the through and/or source association. If you have experienced
373 bugs with conditions appearing in the wrong queries when using nested through associations,
374 this probably solves your problems. *GH #3271*
375
376 *Jon Leighton*
377
378 * If a record is removed from a has_many :through, all of the join records relating to that
379 record should also be removed from the through association's target.
380
381 *Jon Leighton*
382
383 * Fix adding multiple instances of the same record to a has_many :through. *GH #3425*
384
385 *Jon Leighton*
386
387 * Fix creating records in a through association with a polymorphic source type. *GH #3247*

jonleighton authored Nov 4, 2011
396 ## Rails 3.1.1 (October 7, 2011) ##
397
398 * Add deprecation for the preload_associations method. Fixes #3022.
399
400 *Jon Leighton*
401
402 * Don't require a DB connection when loading a model that uses set_primary_key. GH #2807.
403
404 *Jon Leighton*
405
406 * Fix using select() with a habtm association, e.g. Person.friends.select(:name). GH #3030 and
407 \#2923.
408
409 *Hendy Tanata*
410
411 * Fix belongs_to polymorphic with custom primary key on target. GH #3104.
412
413 *Jon Leighton*
414
415 * CollectionProxy#replace should change the DB records rather than just mutating the array.
416 Fixes #3020.
417
418 *Jon Leighton*
419
420 * LRU cache in mysql and sqlite are now per-process caches.
421
422 * lib/active_record/connection_adapters/mysql_adapter.rb: LRU cache keys are per process id.
423 * lib/active_record/connection_adapters/sqlite_adapter.rb: ditto
424 *Aaron Patterson*
425
426 * Support bulk change_table in mysql2 adapter, as well as the mysql one. *Jon Leighton*
427
428 * If multiple parameters are sent representing a date, and some are blank, the
429 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]
430 * ActiveRecord::Base.establish_connection now takes a string that contains
431 a URI that specifies the connection configuration. For example:
432 ActiveRecord::Base.establish_connection 'postgres://localhost/foo'
433
434 * 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.
435
436 So if you were doing this and expecting the second argument to be nil:
437
438 User.find_by_username_and_group("sikachu")
439
440 You'll now get `ArgumentError: wrong number of arguments (1 for 2).` You'll then have to do this:
441
442 User.find_by_username_and_group("sikachu", nil)
443
444 *Prem Sichanugrist*
445
446
447 ## Rails 3.1.0 (August 30, 2011) ##
448
449 * Add a proxy_association method to association proxies, which can be called by association
450 extensions to access information about the association. This replaces proxy_owner etc with
451 proxy_association.owner.
452
453 *Jon Leighton*
454
455 * ActiveRecord::MacroReflection::AssociationReflection#build_record has a new method signature.
456
457 Before: def build_association(*options)
458 After: def build_association(*options, &block)
459
460 Users who are redefining this method to extend functionality should ensure that the block is
461 passed through to ActiveRecord::Base#new.
462
463 This change is necessary to fix https://github.com/rails/rails/issues/1842.
464
465 *Jon Leighton*
466
467 * AR#pluralize_table_names can be used to singularize/pluralize table name of an individual model:
468
469 class User < ActiveRecord::Base
470 self.pluralize_table_names = false
471 end
472
473 Previously this could only be set globally for all models through ActiveRecord::Base.pluralize_table_names. *Guillermo Iguaran*
474
475 * Add block setting of attributes to singular associations:
476
477 class User < ActiveRecord::Base
478 has_one :account
479 end
480
481 user.build_account{ |a| a.credit_limit => 100.0 }
482
483 The block is called after the instance has been initialized. *Andrew White*
484
485 * 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*
486
487 * CSV Fixtures are deprecated and support will be removed in Rails 3.2.0
488
489 * AR#new, AR#create, AR#create!, AR#update_attributes and AR#update_attributes! all accept a second hash as option that allows you
490 to specify which role to consider when assigning attributes. This is built on top of ActiveModel's
491 new mass assignment capabilities:
492
493 class Post < ActiveRecord::Base
494 attr_accessible :title
495 attr_accessible :title, :published_at, :as => :admin
496 end
497
498 Post.new(params[:post], :as => :admin)
499
500 assign_attributes() with similar API was also added and attributes=(params, guard) was deprecated.
501
502 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.
503
504 *Josh Kalderimis*
505
506 * default_scope can take a block, lambda, or any other object which responds to `call` for lazy
507 evaluation:
508
509 default_scope { ... }
510 default_scope lambda { ... }
511 default_scope method(:foo)
512
513 This feature was originally implemented by Tim Morgan, but was then removed in favour of
514 defining a 'default_scope' class method, but has now been added back in by Jon Leighton.
515 The relevant lighthouse ticket is #1812.
516
517 * Default scopes are now evaluated at the latest possible moment, to avoid problems where
518 scopes would be created which would implicitly contain the default scope, which would then
519 be impossible to get rid of via Model.unscoped.
520
521 Note that this means that if you are inspecting the internal structure of an
522 ActiveRecord::Relation, it will *not* contain the default scope, though the resulting
523 query will do. You can get a relation containing the default scope by calling
524 ActiveRecord#with_default_scope, though this is not part of the public API.
525
526 *Jon Leighton*
527
528 * If you wish to merge default scopes in special ways, it is recommended to define your default
529 scope as a class method and use the standard techniques for sharing code (inheritance, mixins,
530 etc.):
531
532 class Post < ActiveRecord::Base
533 def self.default_scope
534 where(:published => true).where(:hidden => false)
535 end
536 end
537
538 *Jon Leighton*
539
540 * PostgreSQL adapter only supports PostgreSQL version 8.2 and higher.
541
542 * ConnectionManagement middleware is changed to clean up the connection pool
543 after the rack body has been flushed.
544
545 * Added an update_column method on ActiveRecord. This new method updates a given attribute on an object, skipping validations and callbacks.
546 It is recommended to use #update_attribute unless you are sure you do not want to execute any callback, including the modification of
547 the updated_at column. It should not be called on new records.
548 Example:
549
550 User.first.update_column(:name, "sebastian") # => true
551
552 *Sebastian Martinez*
553
554 * Associations with a :through option can now use *any* association as the
555 through or source association, including other associations which have a
556 :through option and has_and_belongs_to_many associations
557
558 *Jon Leighton*
559
560 * The configuration for the current database connection is now accessible via
561 ActiveRecord::Base.connection_config. *fxn*
562
563 * limits and offsets are removed from COUNT queries unless both are supplied.
564 For example:
565
566 People.limit(1).count # => 'SELECT COUNT(*) FROM people'
567 People.offset(1).count # => 'SELECT COUNT(*) FROM people'
568 People.limit(1).offset(1).count # => 'SELECT COUNT(*) FROM people LIMIT 1 OFFSET 1'
569
570 *lighthouse #6262*
571
572 * ActiveRecord::Associations::AssociationProxy has been split. There is now an Association class
573 (and subclasses) which are responsible for operating on associations, and then a separate,
574 thin wrapper called CollectionProxy, which proxies collection associations.
575
576 This prevents namespace pollution, separates concerns, and will allow further refactorings.
577
578 Singular associations (has_one, belongs_to) no longer have a proxy at all. They simply return
579 the associated record or nil. This means that you should not use undocumented methods such
580 as bob.mother.create - use bob.create_mother instead.
581
582 *Jon Leighton*
583
584 * Make has_many :through associations work correctly when you build a record and then save it. This
585 requires you to set the :inverse_of option on the source reflection on the join model, like so:
586
587 class Post < ActiveRecord::Base
588 has_many :taggings
589 has_many :tags, :through => :taggings
590 end
591
592 class Tagging < ActiveRecord::Base
593 belongs_to :post
594 belongs_to :tag, :inverse_of => :tagging # :inverse_of must be set!
595 end
596
597 class Tag < ActiveRecord::Base
598 has_many :taggings
599 has_many :posts, :through => :taggings
600 end
601
602 post = Post.first
603 tag = post.tags.build :name => "ruby"
604 tag.save # will save a Taggable linking to the post
605
606 *Jon Leighton*
607
608 * Support the :dependent option on has_many :through associations. For historical and practical
609 reasons, :delete_all is the default deletion strategy employed by association.delete(*records),
610 despite the fact that the default strategy is :nullify for regular has_many. Also, this only
611 works at all if the source reflection is a belongs_to. For other situations, you should directly
612 modify the through association.
613
614 *Jon Leighton*
615
616 * Changed the behaviour of association.destroy for has_and_belongs_to_many and has_many :through.
617 From now on, 'destroy' or 'delete' on an association will be taken to mean 'get rid of the link',
618 not (necessarily) 'get rid of the associated records'.
619
620 Previously, has_and_belongs_to_many.destroy(*records) would destroy the records themselves. It
621 would not delete any records in the join table. Now, it deletes the records in the join table.
622
623 Previously, has_many_through.destroy(*records) would destroy the records themselves, and the
624 records in the join table. [Note: This has not always been the case; previous version of Rails
625 only deleted the records themselves.] Now, it destroys only the records in the join table.
626
627 Note that this change is backwards-incompatible to an extent, but there is unfortunately no
628 way to 'deprecate' it before changing it. The change is being made in order to have
629 consistency as to the meaning of 'destroy' or 'delete' across the different types of associations.
630
631 If you wish to destroy the records themselves, you can do records.association.each(&:destroy)
632
633 *Jon Leighton*
634
635 * 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*
636
637 Example:
638
639 change_table(:users, :bulk => true) do |t|
640 t.string :company_name
641 t.change :birthdate, :datetime
642 end
643
644 This will now result in:
645
646 ALTER TABLE `users` ADD COLUMN `company_name` varchar(255), CHANGE `updated_at` `updated_at` datetime DEFAULT NULL
647
648 * Removed support for accessing attributes on a has_and_belongs_to_many join table. This has been
649 documented as deprecated behaviour since April 2006. Please use has_many :through instead.
650 *Jon Leighton*
651
652 * Added a create_association! method for has_one and belongs_to associations. *Jon Leighton*
653
654 * Migration files generated from model and constructive migration generators
655 (for example, add_name_to_users) use the reversible migration's `change`
656 method instead of the ordinary `up` and `down` methods. *Prem Sichanugrist*
657
658 * Removed support for interpolating string SQL conditions on associations. Instead, you should
659 use a proc, like so:
660
661 Before:
662
663 has_many :things, :conditions => 'foo = #{bar}'
664
665 After:
666
667 has_many :things, :conditions => proc { "foo = #{bar}" }
668
669 Inside the proc, 'self' is the object which is the owner of the association, unless you are
670 eager loading the association, in which case 'self' is the class which the association is within.
671
672 You can have any "normal" conditions inside the proc, so the following will work too:
673
674 has_many :things, :conditions => proc { ["foo = ?", bar] }
675
676 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
677 'record' to get the record being inserted or deleted. This is now passed as an argument to
678 the proc.
679
680 * Added ActiveRecord::Base#has_secure_password (via ActiveModel::SecurePassword) to encapsulate dead-simple password usage with BCrypt encryption and salting [DHH]. Example:
681
682 # Schema: User(name:string, password_digest:string, password_salt:string)
683 class User < ActiveRecord::Base
684 has_secure_password
685 end
686
687 user = User.new(:name => "david", :password => "", :password_confirmation => "nomatch")
688 user.save # => false, password required
689 user.password = "mUc3m00RsqyRe"
690 user.save # => false, confirmation doesn't match
691 user.password_confirmation = "mUc3m00RsqyRe"
692 user.save # => true
693 user.authenticate("notright") # => false
694 user.authenticate("mUc3m00RsqyRe") # => user
695 User.find_by_name("david").try(:authenticate, "notright") # => nil
696 User.find_by_name("david").try(:authenticate, "mUc3m00RsqyRe") # => user
697
698
699 * When a model is generated add_index is added by default for belongs_to or references columns
700
701 rails g model post user:belongs_to will generate the following:
702
703 class CreatePosts < ActiveRecord::Migration
704 def up
705 create_table :posts do |t|
706 t.belongs_to :user
707 t.timestamps
708 end
709
710 add_index :posts, :user_id
711 end
712
713 def down
714 drop_table :posts
715 end
716 end
717
718 *Santiago Pastorino*
719
720 * Setting the id of a belongs_to object will update the reference to the
721 object. [#2989 state:resolved]
722 * ActiveRecord::Base#dup and ActiveRecord::Base#clone semantics have changed
723 to closer match normal Ruby dup and clone semantics.
724 * Calling ActiveRecord::Base#clone will result in a shallow copy of the record,
725 including copying the frozen state. No callbacks will be called.
726 * Calling ActiveRecord::Base#dup will duplicate the record, including calling
727 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.
728 * Migrations can be defined as reversible, meaning that the migration system
729 will figure out how to reverse your migration. To use reversible migrations, just define the "change" method. For example:
730 class MyMigration < ActiveRecord::Migration
731 def change
732 create_table(:horses) do
733 t.column :content, :text
734 t.column :remind_at, :datetime
735 end
736 end
737 end
738
739 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.
740 * Migrations should use instance methods rather than class methods:
741 class FooMigration < ActiveRecord::Migration
742 def up
743 ...
744 end
745 end
746
747 *Aaron Patterson*
748
749 * has_one maintains the association with separate after_create/after_update instead
750 of a single after_save. *fxn*
751
752 * The following code:
753
754 Model.limit(10).scoping { Model.count }
755
756 now generates the following SQL:
757
758 SELECT COUNT(*) FROM models LIMIT 10
759
760 This may not return what you want. Instead, you may with to do something
761 like this:
762
763 Model.limit(10).scoping { Model.all.size }
764
765 *Aaron Patterson*

768 ## Rails 3.0.7 (April 18, 2011) ##
769
770 * Destroying records via nested attributes works independent of reject_if LH #6006 *Durran Jordan*
771
772 * Delegate any? and many? to Model.scoped for consistency *Andrew White*
773
774 * Quote the ORDER BY clause in batched finds - fixes #6620 *Andrew White*
775
776 * Change exists? so records are not instantiated - fixes #6127. This prevents after_find
777 and after_initialize callbacks being triggered when checking for record existence.
778 *Andrew White*
779
780 * Fix performance bug with attribute accessors which only occurred on Ruby 1.8.7, and ensure we
781 cache type-casted values when the column returned from the db contains non-standard chars.
782 *Jon Leighton*
783
784 * Fix a performance regression introduced here 86acbf1cc050c8fa8c74a10c735e467fb6fd7df8
785 related to read_attribute method *Stian Grytøyr*
786
787
788 ## Rails 3.0.6 (April 5, 2011) ##
789
790 * Un-deprecate reorder method *Sebastian Martinez*
791
792 * Extensions are applied when calling +except+ or +only+ on relations.
793 Thanks to Iain Hecker.
794
795 * Schemas set in set_table_name are respected by the mysql adapter. LH #5322
796
797 * Fixed a bug when empty? was called on a grouped Relation that wasn't loaded.
798 LH #5829
799
800 * Reapply extensions when using except and only. Thanks Iain Hecker.
801
802 * Binary data is escaped when being inserted to SQLite3 Databases. Thanks
803 Naruse!
804
805
806 ## Rails 3.0.5 (February 26, 2011) ##
807
808 * Model.where(:column => 1).where(:column => 2) will always produce an AND
809 query.
810 *Aaron Patterson*
811
812 * Deprecated support for interpolated association conditions in the form of :conditions => 'foo = #{bar}'.
813
814 Instead, you should use a proc, like so:
815
816 Before:
817
818 has_many :things, :conditions => 'foo = #{bar}'
819
820 After:
821
822 has_many :things, :conditions => proc { "foo = #{bar}" }
823
824 Inside the proc, 'self' is the object which is the owner of the association, unless you are
825 eager loading the association, in which case 'self' is the class which the association is within.
826
827 You can have any "normal" conditions inside the proc, so the following will work too:
828
829 has_many :things, :conditions => proc { ["foo = ?", bar] }
830
831 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
832 'record' to get the record being inserted or deleted. This is now passed as an argument to
833 the proc.
834
835 *Jon Leighton*
836
837
838 ## Rails 3.0.4 (February 8, 2011) ##
839
840 * Added deprecation warning for has_and_belongs_to_many associations where the join table has
841 additional attributes other than the keys. Access to these attributes is removed in 3.1.
842 Please use has_many :through instead. *Jon Leighton*
843
844
845 ## Rails 3.0.3 (November 16, 2010) ##
846
847 * Support find by class like this: Post.where(:name => Post)
848
849
850 ## Rails 3.0.2 (November 15, 2010) ##
851
852 * Dramatic speed increase (see: http://engineering.attinteractive.com/2010/10/arel-two-point-ohhhhh-yaaaaaa/) *Aaron Patterson*
853
854 * reorder is deprecated in favor of except(:order).order(...) *Santiago Pastorino*
855
856 * except is now AR public API
857
858 Model.order('name').except(:order).order('salary')
859
860 generates:
861
862 SELECT * FROM models ORDER BY salary
863
864 *Santiago Pastorino*
865
866 * The following code:
867
868 Model.limit(10).scoping { Model.count }
869
870 now generates the following SQL:
871
872 SELECT COUNT(*) FROM models LIMIT 10
873
874 This may not return what you want. Instead, you may with to do something
875 like this:
876
877 Model.limit(10).scoping { Model.all.size }
878
879 *Aaron Patterson*
880
881
882 ## Rails 3.0.1 (October 15, 2010) ##
883
884 * Introduce a fix for CVE-2010-3993
885
886
887 ## Rails 3.0.0 (August 29, 2010) ##
888
889 * Changed update_attribute to not run callbacks and update the record directly in the database *Neeraj Singh*
890
891 * Add scoping and unscoped as the syntax to replace the old with_scope and with_exclusive_scope *José Valim*
892
893 * New rake task, db:migrate:status, displays status of migrations #4947 *Kevin Skoglund*
894
895 * select and order for ActiveRecord now always concatenate nested calls. Use reorder if you want the original order to be overwritten *Santiago Pastorino*
896
897 * PostgreSQL: ensure the database time zone matches Ruby's time zone #4895 *Aaron Patterson*
898
899 * Fixed that ActiveRecord::Base.compute_type would swallow NoMethodError #4751 *Andrew Bloomgarden, Andrew White*
900
901 * Add index length support for MySQL. #1852 *Emili Parreno, Pratik Naik*
902
903 Example:
904
905 add_index(:accounts, :name, :name => 'by_name', :length => 10)
906 => CREATE INDEX by_name ON accounts(name(10))
907
908 add_index(:accounts, [:name, :surname], :name => 'by_name_surname', :length => {:name => 10, :surname => 15})

910
911 * find_or_create_by_attr(value, ...) works when attr is protected. #4457 *Santiago Pastorino, Marc-André Lafortune*
912
913 * New callbacks: after_commit and after_rollback. Do expensive operations like image thumbnailing after_commit instead of after_save. #2991 *Brian Durand*
914
915 * 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*
916
917 * 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*
918
919 * PostgreSQL: drop support for old postgres driver. Use pg 0.9.0 or later. *Jeremy Kemper*

928 def posts_count
929 Post.count(:user_id => to_a.map(&:id))
930 end
931 end
932
933 * To prefix the table names of all models in a module, define self.table_name_prefix on the module. #4032 *Andrew White*
934
935 * 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*
936
937 * 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*
938
939 * Allow relations to be used as scope.
940
941 class Item
942 scope :red, where(:colour => 'red')
943 end
944
945 Item.red.limit(10) # Ten red items
946

955
956 * Add Relation#delete_all. *Pratik Naik*
957

963
964 * Add Relation#count. *Pratik Naik*
965
966 legends = People.where("age > 100")
967 legends.count
968 legends.count(:age, :distinct => true)
969 legends.select('id').count
970
971 * Add Model.readonly and association_collection#readonly finder method. *Pratik Naik*
972
973 Post.readonly.to_a # Load all posts in readonly mode
974 @user.items.readonly(false).to_a # Load all the user items in writable mode
975
976 * Add .lock finder method *Pratik Naik*
977
978 User.lock.where(:name => 'lifo').to_a
979

996 red_items.exists?
997 red_items.exists?(1)
998
999 * Add find(ids) to relations. *Pratik Naik*
1000
1001 old_users = User.order("age DESC")
1002 old_users.find(1)
1003 old_users.find(1, 2, 3)
1004
1005 * Add new finder methods to association collection. *Pratik Naik*
1006
1007 class User < ActiveRecord::Base
1008 has_many :items
1009 end
1010
1011 user = User.first
1012 user.items.where(:items => {:colour => 'red'})
1013 user.items.select('items.id')
1014
1015 * Add relation.reload to force reloading the records. *Pratik Naik*
1016
1017 topics = Topic.scoped
1018 topics.to_a # force load
1019 topics.first # returns a cached record
1020 topics.reload
1021 topics.first # Fetches a new record from the database
1022
1023 * Rename Model.conditions and relation.conditions to .where. *Pratik Naik*
1024
1025 Before :
1026 User.conditions(:name => 'lifo')
1027 User.select('id').conditions(["age > ?", 21])
1028

1038 posts.each {|p| puts p.id } # Fires "select id from posts order by name"
1039
1040 * Model.scoped now returns a relation if invoked without any arguments. *Pratik Naik*
1041
1042 Example :
1043
1044 posts = Post.scoped
1045 posts.size # Fires "select count(*) from posts" and returns the count
1046 posts.each {|p| puts p.name } # Fires "select * from posts" and loads post objects
1047
1048 * Association inverses for belongs_to, has_one, and has_many. Optimization to reduce database queries. #3533 *Murray Steele*
1049
1050 # post.comments sets each comment's post without needing to :include
1051 class Post < ActiveRecord::Base
1052 has_many :comments, :inverse_of => :post
1053 end
1054
1055 * MySQL: add_ and change_column support positioning. #3286 *Ben Marini*

1060
1061 * PostgreSQL: XML datatype support. #1874 *Leonardo Borges*
1062
1063 * 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*
1064
1065 * SQLite: drop support for 'dbfile' option in favor of 'database.' #2363 *Paul Hinze, Jeremy Kemper*
1066
1067 * Added :primary_key option to belongs_to associations. #765 *Szymon Nowak, Philip Hallstrom, Noel Rocha*
1068 # employees.company_name references companies.name
1069 Employee.belongs_to :company, :primary_key => 'name', :foreign_key => 'company_name'
1070
1071 * Implement #many? for NamedScope and AssociationCollection using #size. #1500 *Chris Kampmeier*

1108
1109 class Person < ActiveRecord::Base
1110 default_scope :order => 'last_name, first_name'
1111 end
1112
1113 class Company < ActiveRecord::Base

1140 * Added find_last_by dynamic finder #762 *Emilio Tagua*
1141
1142 * Internal API: configurable association options and build_association method for reflections so plugins may extend and override. #985 *Hongli Lai (Phusion)*

1164
1165 * Allow conditions on multiple tables to be specified using hash. [Pratik Naik]. Example:
1166
1167 User.all :joins => :items, :conditions => { :age => 10, :items => { :color => 'black' } }
1168 Item.first :conditions => { :items => { :color => 'red' } }

1243
1244 * Improve documentation. *Xavier Noria, Jack Danger Canty, leethal*

1247
1248 Post.find(1).to_json # => {"title": ...}
1249 config.active_record.include_root_in_json = true
1250 Post.find(1).to_json # => {"post": {"title": ...}}

1254 * PostgreSQL: create_ and drop_database support. #9042 *ez, pedz, Nick Sieger*
1255
1256 * Ensure that validates_uniqueness_of works with with_scope. Closes #9235. *Nik Wakelin, cavalle*
1257
1258 * Partial updates include only unsaved attributes. Off by default; set YourClass.partial_updates = true to enable. *Jeremy Kemper*

Also added rake db:migrate:up/down to apply individual migrations that may need to be run when you merge branches #11458 *John Barnette*
1267
1268 * Fixed that has_many :through would ignore the hash conditions #11447 *Emilio Tagua*
1269
1270 * Fix issue where the :uniq option of a has_many :through association is ignored when find(:all) is called. Closes #9407 *cavalle*
1271
1272 * Fix duplicate table alias error when including an association with a has_many :through association on the same join table. Closes #7310 *cavalle*

1557 belongs_to :article, :counter_cache => :comments_count
1558 end
1559
1560 class Article < ActiveRecord::Base
1561 attr_readonly :approved_comments_count

1580 * Added ActiveRecord::Base#to_json/from_json *David Heinemeier Hansson, Cheah Chu Yeow*
1581
1582 * Added ActiveRecord::Base#from_xml [David Heinemeier Hansson]. Example:

1585 Person.new.from_xml(xml).name # => "David"
1586
1587 * Define dynamic finders as real methods after first usage. *bscofield*

1598
1599 * Extract Firebird, FrontBase, and OpenBase adapters into gems. #9508, #9509, #9510 *Jeremy Kemper*
1600

1625 For more information see: http://dev.rubyonrails.org/ticket/8049
1626
1627 * Don't clobber includes passed to has_many.count *Jack Danger Canty*
1628
1629 * Make sure has_many uses :include when counting *Jack Danger Canty*
1630
1631 * Change the implementation of ActiveRecord's attribute reader and writer methods *Michael Koziarski*
1632 - 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.
1633 * Perform a deep #dup on query cache results so that modifying activerecord attributes does not modify the cached attributes. *Rick Olson*

1641
1642 validates_presence_of :identity_url, :if => using_open_id?
1643 validates_presence_of :username, :unless => using_open_id?
1644 validates_presence_of :password, :unless => using_open_id?

1648 * Fix and properly document/test count(column_name) usage. Closes #8999 *Pratik Naik*
1649
1650 * Remove deprecated count(conditions=nil, joins=nil) usage. Closes #8993 *Pratik Naik*
1651
1652 * Change belongs_to so that the foreign_key assumption is taken from the association name, not the class name. Closes #8992 *Josh Susser*
1653
1654 OLD
1655 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is user_id
1656
1657 NEW
1658 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is visitor_id
1659
1660 * Remove spurious tests from deprecated_associations_test, most of these aren't deprecated, and are duplicated in associations_test. Closes #8987 *Pratik Naik*
1661
1662 * Make create! on a has_many :through association return the association object. Not the collection. Closes #8786 *Pratik Naik*

1667
1668 * Define collection singular ids method for has_many :through associations. #8763 *Pratik Naik*

1671
1672 * Fix polymorphic has_one associations declared in an abstract class. #8638 *Pratik Naik, Dax Huiberts*
1673
1674 * Fixed validates_associated should not stop on the first error. #4276 *mrj, Manfred Stienstra, Josh Peek*

1697
1698 * Raise an exception if both attr_protected and attr_accessible are declared. #8507 *stellsmi*
1699
1700 * SQLite, MySQL, PostgreSQL, Oracle: quote column names in column migration SQL statements. #8466 *marclove, lorenjohnson*
1701
1702 * Allow nil serialized attributes with a set class constraint. #7293 *sandofsky*
1703
1704 * Oracle: support binary fixtures. #7987 *Michael Schoen*
1705

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*
1723
1724 * Ensure that associations with :dependent => :delete_all respect :conditions option. Closes #8034 *Jack Danger Canty, Josh Peek, Rick Olson*

1744 * Add documentation caveat about when to use count_by_sql. *fearoffish*
1745
1746 * Enhance documentation for increment_counter and decrement_counter. *fearoffish*
1747
1748 * Provide brief introduction to what optimistic locking is. *fearoffish*
1749
1750 * Add documentation for :encoding option to mysql adapter. *marclove*
1751
1752 * Added short-hand declaration style to migrations (inspiration from Sexy Migrations, http://errtheblog.com/post/2381) [David Heinemeier Hansson]. Example:
1753
1754 create_table "products" do |t|
1755 t.column "shop_id", :integer
1756 t.column "creator_id", :integer
1757 t.column "name", :string, :default => "Untitled"
1758 t.column "value", :string, :default => "Untitled"
1759 t.column "created_at", :datetime
1760 t.column "updated_at", :datetime
1761 end
1762
1763 ...can now be written as:
1764
1765 create_table :products do |t|
1766 t.integer :shop_id, :creator_id
1767 t.string :name, :value, :default => "Untitled"
1768 t.timestamps
1769 end
1770
1771 * 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*
1772
1773 * Improve performance of calling .create on has_many :through associations. *evan*
1774
1775 * Improved cloning performance by relying less on exception raising #8159 *Blaine*
1776
1777 * Added ActiveRecord::Base.inspect to return a column-view like #<Post id:integer, title:string, body:text> *David Heinemeier Hansson*
1778
1779 * Added yielding of Builder instance for ActiveRecord::Base#to_xml calls *David Heinemeier Hansson*
1780
1781 * Small additions and fixes for ActiveRecord documentation. Closes #7342 *Jeremy McAnally*
1782
1783 * Add helpful debugging info to the ActiveRecord::StatementInvalid exception in ActiveRecord::ConnectionAdapters::SqliteAdapter#table_structure. Closes #7925. *court3nay*
1784
1785 * SQLite: binary escaping works with $KCODE='u'. #7862 *tsuka*
1786
1787 * Base#to_xml supports serialized attributes. #7502 *jonathan*
1788
1789 * Base.update_all :order and :limit options. Useful for MySQL updates that must be ordered to avoid violating unique constraints. *Jeremy Kemper*
1790
1791 * 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*
1792
1793 * 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*
1794
1795 * 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*
1796
1797 * 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*
1798
1799 * Allow a polymorphic :source for has_many :through associations. Closes #7143 *protocool*
1800
1801 * Consistent public/protected/private visibility for chained methods. #7813 *Dan Manges*
1802
1803 * Oracle: fix quoted primary keys and datetime overflow. #7798 *Michael Schoen*
1804
1805 * Consistently quote primary key column names. #7763 *toolmantim*
1806
1807 * Fixtures: fix YAML ordered map support. #2665 *Manuel Holtgrewe, nfbuckley*
1808
1809 * DateTimes assume the default timezone. #7764 *Geoff Buesing*
1810
1811 * Sybase: hide timestamp columns since they're inherently read-only. #7716 *Mike Joyce*
1812
1813 * Oracle: overflow Time to DateTime. #7718 *Michael Schoen*
1814
1815 * PostgreSQL: don't use async_exec and async_query with postgres-pr. #7727, #7762 *flowdelic, toolmantim*
1816
1817 * Fix has_many :through << with custom foreign keys. #6466, #7153 *naffis, Rich Collins*
1818
1819 * Test DateTime native type in migrations, including an edge case with dates
1820 during calendar reform. #7649, #7724 [fedot, Geoff Buesing]
1821 * SQLServer: correctly schema-dump tables with no indexes or descending indexes. #7333, #7703 *Jakob Skjerning, Tom Ward*
1822
1823 * SQLServer: recognize real column type as Ruby float. #7057 *sethladd, Tom Ward*
1824
1825 * Added fixtures :all as a way of loading all fixtures in the fixture directory at once #7214 *Manfred Stienstra*
1826
1827 * Added database connection as a yield parameter to ActiveRecord::Base.transaction so you can manually rollback [David Heinemeier Hansson]. Example:
1828
1829 transaction do |transaction|
1830 david.withdrawal(100)
1831 mary.deposit(100)
1832 transaction.rollback! # rolls back the transaction that was otherwise going to be successful
1833 end
1834
1835 * Made increment_counter/decrement_counter play nicely with optimistic locking, and added a more general update_counters method *Jamis Buck*
1836
1837 * 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*
1838 Task.cache { Task.find(1); Task.find(1) } # => 1 query
1839
1840 * 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*
1841
1842 * Oracle: fix lob and text default handling. #7344 *gfriedrich, Michael Schoen*
1843
1844 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
1845
1846 * MySQL: blob and text columns may not have defaults in 5.x. Update fixtures schema for strict mode. #6695 *Dan Kubb*
1847
1848 * 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*
1849
1850 * MySQL: SET SQL_AUTO_IS_NULL=0 so 'where id is null' doesn't select the last inserted id. #6778 *Jonathan Viney, timc*
1851
1852 * Use Date#to_s(:db) for quoted dates. #7411 *Michael Schoen*
1853
1854 * Don't create instance writer methods for class attributes. Closes #7401 *Rick Olson*
1855
1856 * Docs: validations examples. #7343 *zackchandler*
1857
1858 * Add missing tests ensuring callbacks work with class inheritance. Closes #7339 *sandofsky*
1859
1860 * Fixtures use the table name and connection from set_fixture_class. #7330 *Anthony Eden*
1861
1862 * Remove useless code in #attribute_present? since 0 != blank?. Closes #7249 *Josh Susser*
1863
1864 * Fix minor doc typos. Closes #7157 *Josh Susser*
1865
1866 * Fix incorrect usage of #classify when creating the eager loading join statement. Closes #7044 *Josh Susser*
1867
1868 * SQLServer: quote table name in indexes query. #2928 *keithm@infused.org*
1869
1870 * Subclasses of an abstract class work with single-table inheritance. #5704, #7284 *BertG, nick+rails@ag.arizona.edu*
1871
1872 * Make sure sqlite3 driver closes open connections on disconnect *Rob Rasmussen*
1873
1874 * [DOC] clear up some ambiguity with the way has_and_belongs_to_many creates the default join table name. #7072 *Jeremy McAnally*
1875
1876 * change_column accepts :default => nil. Skip column options for primary keys. #6956, #7048 *Dan Manges, Jeremy Kemper*
1877
1878 * 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*
1879
1880 * Oracle: create_table takes a :sequence_name option to override the 'tablename_seq' default. #7000 *Michael Schoen*
1881
1882 * MySQL: retain SSL settings on reconnect. #6976 *randyv2*
1883
1884 * Apply scoping during initialize instead of create. Fixes setting of foreign key when using find_or_initialize_by with scoping. *Cody Fauser*
1885
1886 * SQLServer: handle [quoted] table names. #6635 *rrich*
1887
1888 * acts_as_nested_set works with single-table inheritance. #6030 *Josh Susser*
1889
1890 * PostgreSQL, Oracle: correctly perform eager finds with :limit and :order. #4668, #7021 *eventualbuddha, Michael Schoen*
1891
1892 * Pass a range in :conditions to use the SQL BETWEEN operator. #6974 *Dan Manges*
1893 Student.find(:all, :conditions => { :grade => 9..12 })
1894
1895 * Fix the Oracle adapter for serialized attributes stored in CLOBs. Closes #6825 *mschoen, tdfowler*
1896
1897 * [DOCS] Apply more documentation for ActiveRecord Reflection. Closes #4055 *Robby Russell*
1898
1899 * [DOCS] Document :allow_nil option of #validate_uniqueness_of. Closes #3143 *Caio Chassot*
1900
1901 * Bring the sybase adapter up to scratch for 1.2 release. *jsheets*
1902
1903 * Rollback new_record? and id when an exception is raised in a save callback. #6910 *Ben Curren, outerim*
1904
1905 * Pushing a record on an association collection doesn't unnecessarily load all the associated records. *Obie Fernandez, Jeremy Kemper*
1906
1907 * Oracle: fix connection reset failure. #6846 *leonlleslie*
1908
1909 * Subclass instantiation doesn't try to explicitly require the corresponding subclass. #6840 *leei, Jeremy Kemper*
1910
1911 * 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*
1912
1913 * 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*
1914
1915 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
1916
1917 * Add AssociationCollection#create! to be consistent with AssociationCollection#create when dealing with a foreign key that is a protected attribute *Cody Fauser*
1918
1919 * 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*
1920
1921 * Change fixture_path to a class inheritable accessor allowing test cases to have their own custom set of fixtures. #6672 *Zach Dennis*
1922
1923 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
1924
1925 * Simplify query_attribute by typecasting the attribute value and checking whether it's nil, false, zero or blank. #6659 *Jonathan Viney*
1926
1927 * 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*
1928
1929 * Run validations in the order they were declared. #6657 *obrie*
1930
1931 * 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*
1932
1933 * Simplify association proxy implementation by factoring construct_scope out of method_missing. #6643 *martin*
1934
1935 * Oracle: automatically detect the primary key. #6594 *vesaria, Michael Schoen*
1936
1937 * 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*
1938
1939 * Don't inspect unloaded associations. #2905 *lmarlow*
1940
1941 * SQLite: use AUTOINCREMENT primary key in >= 3.1.0. #6588, #6616 *careo, lukfugl*
1942
1943 * Cache inheritance_column. #6592 *Stefan Kaes*
1944
1945 * Firebird: decimal/numeric support. #6408 *macrnic*
1946
1947 * make add_order a tad faster. #6567 *Stefan Kaes*
1948
1949 * Find with :include respects scoped :order. #5850
1950
1951 * Support nil and Array in :conditions => { attr => value } hashes. #6548 *Assaf, Jeremy Kemper*
1952 find(:all, :conditions => { :topic_id => [1, 2, 3], :last_read => nil }
1953
1954 * 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*
1955
1956 * SQLite: fix calculations workaround, remove count(distinct) query rewrite, cleanup test connection scripts. *Jeremy Kemper*
1957
1958 * SQLite: count(distinct) queries supported in >= 3.2.6. #6544 *Bob Silva*
1959
1960 * Dynamically generate reader methods for serialized attributes. #6362 *Stefan Kaes*
1961
1962 * Deprecation: object transactions warning. *Jeremy Kemper*
1963
1964 * has_one :dependent => :nullify ignores nil associates. #4848, #6528 *bellis@deepthought.org, janovetz, Jeremy Kemper*
1965
1966 * 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*
1967
1968 * Make add_column use the options hash with the Sqlite Adapter. Closes #6464 *obrie*
1969
1970 * Document other options available to migration's add_column. #6419 *grg*
1971
1972 * MySQL: all_hashes compatibility with old MysqlRes class. #6429, #6601 *Jeremy Kemper*
1973
1974 * Fix has_many :through to add the appropriate conditions when going through an association using STI. Closes #5783. *Jonathan Viney*
1975
1976 * fix select_limited_ids_list issues in postgresql, retain current behavior in other adapters *Rick Olson*
1977
1978 * Restore eager condition interpolation, document it's differences *Rick Olson*
1979

1981
1982 * Add #delete support to has_many :through associations. Closes #6049 *Martin Landers*
1983
1984 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
1985
1986 * 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*
1987
1988 * 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*
1989
1990 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*
1991
1992 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
1993
1994 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
1995
1996 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
1997
1998 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
1999
2000 * 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*
2001
2002 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
2003
2004 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*
2005
2006 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*

2013
2014 * Mock Time.now for more accurate Touch mixin tests. #6213 *Dan Peterson*
2015
2016 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
2017
2018 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
2019
2020 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
2021
2022 * 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*
2023
2024 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
2025
2026 * Document validates_presences_of behavior with booleans: you probably want validates_inclusion_of :attr, :in => [true, false]. #2253 *Bob Silva*
2027
2028 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
2029
2030 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
2031
2032 * Deprecation: update docs. #5998 *Jakob Skjerning, Kevin Clark*
2033
2034 * Add some XmlSerialization tests for ActiveRecord *Rick Olson*
2035
2036 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
2037
2038 * Tighten rescue clauses. #5985 *james@grayproductions.net*
2039
2040 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
2041
2042 * 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*
2043
2044 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
2045
2046 * 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*
2047
2048 * SQLServer: fix eager association test. #5901 *Tom Ward*
2049
2050 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
2051
2052 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
2053
2054 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*
2055
2056 * MySQL: update test schema for MySQL 5 strict mode. #5861 *Tom Ward*
2057
2058 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2059
2060 * 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*
2061
2062 * 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*
2063
2064 # Create a tagging to associate the post and tag.
2065 post.tags << Tag.find_by_name('old')
2066 post.tags.create! :name => 'general'
2067
2068 # Would have been:
2069 post.taggings.create!(:tag => Tag.find_by_name('finally')
2070 transaction do
2071 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
2072 end
2073
2074 * Cache nil results for :included has_one associations also. #5787 *Michael Schoen*
2075
2076 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
2077
2078 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
2079 Example: Invoice::Lineitem is given table name invoice_lineitems
2080
2081 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2082 # people_active_last_name_index, people_active_deactivated_at_index
2083 add_index :people, [:active, :last_name]
2084 add_index :people, [:active, :deactivated_at]
2085 remove_index :people, [:active, :last_name]
2086 remove_index :people, [:active, :deactivated_at]
2087
2088 WARNING: backward-incompatibility. Multicolumn indexes created before this
2089 revision were named using the first column name only. Now they're uniquely
2090 named using all indexed columns.
2091
2092 To remove an old multicolumn index, remove_index :table_name, :first_column
2093
2094 * Fix for deep includes on the same association. *richcollins@gmail.com*
2095
2096 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
2097
2098 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
2099
2100 * Document find's :from option. Closes #5762. *andrew@redlinesoftware.com*
2101
2102 * 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*
2103
2104 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
2105
2106 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
2107
2108 * Add documentation for how to disable timestamps on a per model basis. Closes #5684. *matt@mattmargolis.net Marcel Molina Jr.*
2109
2110 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
2111
2112 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
2113
2114 * Formally deprecate the deprecated finders. *Michael Koziarski*
2115
2116 * Formally deprecate rich associations. *Michael Koziarski*
2117
2118 * Fixed that default timezones for new / initialize should uphold utc setting #5709 *daniluk@yahoo.com*
2119
2120 * Fix announcement of very long migration names. #5722 *blake@near-time.com*
2121
2122 * The exists? class method should treat a string argument as an id rather than as conditions. #5698 *jeremy@planetargon.com*
2123
2124 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
2125
2126 * Added support for conditions on Base.exists? #5689 [Josh Peek]. Examples:
2127
2128 assert (Topic.exists?(:author_name => "David"))
2129 assert (Topic.exists?(:author_name => "Mary", :approved => true))

2145
2146 * 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*
2147
2148 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2149
2150 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2151
2152 * 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*
2153
2154 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*
2155
2156 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2157
2158 * Update callbacks documentation. #3970 *Robby Russell <robby@planetargon.com>*
2159
2160 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2161
2162 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2163
2164 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2165
2166 * 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*
2167
2168 * 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*
2169
2170 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2171
2172 * Minor tweak to improve performance of ActiveRecord::Base#to_param.
2173
2174 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2175
2176 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2177
2178 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2179
2180 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2181
2182 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2183
2184 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2185
2186 * 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*
2187 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2188 Person.transaction do
2189 # select * from people where id=1 for update
2190 person = Person.find(1, :lock => true)
2191 person.visits += 1
2192 person.save!
2193 end
2194
2195 * 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*
2196
2197 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*

2199 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2200
2201 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2202
2203 * 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*
2204
2205 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2206
2207 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2208
2209 ...is the same as:
2210 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2211
2212 This makes it easier to pass in the options from a form or otherwise outside.
2213

2224
2225 * 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*
2226
2227 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
2228
2229 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
2230
2231 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
2232 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
2233 Foo.find(:first, :conditions => ['bar_id = ?', bar])
2234
2235 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
2236
2237 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
2238
2239 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*

2253
2254 * Fix Oracle boolean support and tests. Closes #5139. *Michael Schoen*
2255
2256 * 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*
2257
2258 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2259
2260 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2261
2262 * 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*

2358
2359 * Don't create instance writer methods for class attributes. *Rick Olson*

2362
2363 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
2364
2365 * 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*
2366

2408
2409 * 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*
2410
2411 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
2412

2415
2416 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
2417
2418 * 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*
2419

2471
2472 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*

2495
2496 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
2497
2498 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
2499
2500 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
2501
2502 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
2503
2504 * 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*
2505
2506 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
2507
2508 * 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*
2509
2510 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
2511
2512 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
2513
2514 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*

2517
2518 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2519
2520 * 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*
2521
2522 * 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*
2523
2524 # Create a tagging to associate the post and tag.
2525 post.tags << Tag.find_by_name('old')
2526 post.tags.create! :name => 'general'
2527
2528 # Would have been:
2529 post.taggings.create!(:tag => Tag.find_by_name('finally')
2530 transaction do
2531 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
2532 end
2533
2534 * Cache nil results for :included has_one associations also. #5787 *Michael Schoen*
2535
2536 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
2537
2538 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
2539 Example: Invoice::Lineitem is given table name invoice_lineitems
2540
2541 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2542 # people_active_last_name_index, people_active_deactivated_at_index
2543 add_index :people, [:active, :last_name]
2544 add_index :people, [:active, :deactivated_at]
2545 remove_index :people, [:active, :last_name]
2546 remove_index :people, [:active, :deactivated_at]
2547
2548 WARNING: backward-incompatibility. Multicolumn indexes created before this
2549 revision were named using the first column name only. Now they're uniquely
2550 named using all indexed columns.
2551
2552 To remove an old multicolumn index, remove_index :table_name, :first_column
2553
2554 * Fix for deep includes on the same association. *richcollins@gmail.com*
2555
2556 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
2557
2558 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
2559
2560 * 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*
2561
2562 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
2563
2564 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
2565
2566 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
2567
2568 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
2569
2570 * Formally deprecate the deprecated finders. *Michael Koziarski*
2571
2572 * Formally deprecate rich associations. *Michael Koziarski*
2573
2574 * Fixed that default timezones for new / initialize should uphold utc setting #5709 *daniluk@yahoo.com*
2575
2576 * Fix announcement of very long migration names. #5722 *blake@near-time.com*
2577
2578 * The exists? class method should treat a string argument as an id rather than as conditions. #5698 *jeremy@planetargon.com*
2579
2580 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
2581
2582 * Added support for conditions on Base.exists? #5689 [Josh Peek]. Examples:
2583
2584 assert (Topic.exists?(:author_name => "David"))
2585 assert (Topic.exists?(:author_name => "Mary", :approved => true))
2586 assert (Topic.exists?(["parent_id = ?", 1]))
2587
2588 * Schema dumper quotes date :default values. *Dave Thomas*
2589
2590 * Calculate sum with SQL, not Enumerable on HasManyThrough Associations. *Dan Peterson*
2591
2592 * Factor the attribute#{suffix} methods out of method_missing for easier extension. *Jeremy Kemper*
2593
2594 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
2595
2596 * Allow #count through a has_many association to accept :include. *Dan Peterson*
2597
2598 * create_table rdoc: suggest :id => false for habtm join tables. *Zed Shaw*
2599
2600 * PostgreSQL: return array fields as strings. #4664 *Robby Russell*
2601
2602 * 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*
2603
2604 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2605
2606 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2607
2608 * 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*
2609
2610 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*
2611
2612 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2613
2614 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2615
2616 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2617
2618 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2619
2620 * 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*
2621
2622 * 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*
2623
2624 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2625
2626 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2627
2628 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2629
2630 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2631
2632 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2633
2634 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2635
2636 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2637
2638 * 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*
2639 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2640 Person.transaction do
2641 # select * from people where id=1 for update
2642 person = Person.find(1, :lock => true)
2643 person.visits += 1
2644 person.save!
2645 end
2646
2647 * 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*
2648
2649 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2650
2651 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2652
2653 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2654
2655 * 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*
2656
2657 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2658
2659 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
