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

242 `MyModel::GeneratedFeatureMethods`. It is included into the model class immediately after

416 * 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.
417
418 So if you were doing this and expecting the second argument to be nil:
419
420 User.find_by_username_and_group("sikachu")
421
422 You'll now get `ArgumentError: wrong number of arguments (1 for 2).` You'll then have to do this:
423
424 User.find_by_username_and_group("sikachu", nil)
425

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

750 ## Rails 3.0.7 (April 18, 2011) ##
751
752 * Destroying records via nested attributes works independent of reject_if LH #6006 *Durran Jordan*
753
754 * Delegate any? and many? to Model.scoped for consistency *Andrew White*
755
756 * Quote the ORDER BY clause in batched finds - fixes #6620 *Andrew White*
757
758 * Change exists? so records are not instantiated - fixes #6127. This prevents after_find
759 and after_initialize callbacks being triggered when checking for record existence.
760 *Andrew White*
761
762 * Fix performance bug with attribute accessors which only occurred on Ruby 1.8.7, and ensure we
763 cache type-casted values when the column returned from the db contains non-standard chars.
764 *Jon Leighton*
765
766 * Fix a performance regression introduced here 86acbf1cc050c8fa8c74a10c735e467fb6fd7df8

770 ## Rails 3.0.6 (April 5, 2011) ##
771
772 * Un-deprecate reorder method *Sebastian Martinez*
773
774 * Extensions are applied when calling +except+ or +only+ on relations.
775 Thanks to Iain Hecker.
776
777 * Schemas set in set_table_name are respected by the mysql adapter. LH #5322
778
779 * Fixed a bug when empty? was called on a grouped Relation that wasn't loaded.
780 LH #5829
781
782 * Reapply extensions when using except and only. Thanks Iain Hecker.
783
784 * Binary data is escaped when being inserted to SQLite3 Databases. Thanks
785 Naruse!
786
787
788 ## Rails 3.0.5 (February 26, 2011) ##
789
790 * Model.where(:column => 1).where(:column => 2) will always produce an AND
791 query.
792 *Aaron Patterson*
793
794 * Deprecated support for interpolated association conditions in the form of :conditions => 'foo = #{bar}'.
795
796 Instead, you should use a proc, like so:
797
798 Before:
799
800 has_many :things, :conditions => 'foo = #{bar}'
801
802 After:
803
804 has_many :things, :conditions => proc { "foo = #{bar}" }
805
806 Inside the proc, 'self' is the object which is the owner of the association, unless you are
807 eager loading the association, in which case 'self' is the class which the association is within.
808
809 You can have any "normal" conditions inside the proc, so the following will work too:
810
811 has_many :things, :conditions => proc { ["foo = ?", bar] }
812
813 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
814 'record' to get the record being inserted or deleted. This is now passed as an argument to
815 the proc.
816
817 *Jon Leighton*
818
819
820 ## Rails 3.0.4 (February 8, 2011) ##
821
822 * Added deprecation warning for has_and_belongs_to_many associations where the join table has
823 additional attributes other than the keys. Access to these attributes is removed in 3.1.
824 Please use has_many :through instead. *Jon Leighton*
825
826
827 ## Rails 3.0.3 (November 16, 2010) ##
828
829 * Support find by class like this: Post.where(:name => Post)
830
831
832 ## Rails 3.0.2 (November 15, 2010) ##
833
834 * Dramatic speed increase (see: http://engineering.attinteractive.com/2010/10/arel-two-point-ohhhhh-yaaaaaa/) *Aaron Patterson*
835
836 * reorder is deprecated in favor of except(:order).order(...) *Santiago Pastorino*
837
838 * except is now AR public API
839
840 Model.order('name').except(:order).order('salary')
841
842 generates:
843
844 SELECT * FROM models ORDER BY salary
845
846 *Santiago Pastorino*
847
848 * The following code:
849
850 Model.limit(10).scoping { Model.count }
851
852 now generates the following SQL:
853
854 SELECT COUNT(*) FROM models LIMIT 10
855
856 This may not return what you want. Instead, you may with to do something
857 like this:
858
859 Model.limit(10).scoping { Model.all.size }
860
861 *Aaron Patterson*
862
863
864 ## Rails 3.0.1 (October 15, 2010) ##
865
866 * Introduce a fix for CVE-2010-3993
867
868
869 ## Rails 3.0.0 (August 29, 2010) ##
870
871 * Changed update_attribute to not run callbacks and update the record directly in the database *Neeraj Singh*
872
873 * Add scoping and unscoped as the syntax to replace the old with_scope and with_exclusive_scope *José Valim*
874
875 * New rake task, db:migrate:status, displays status of migrations #4947 *Kevin Skoglund*
876
877 * select and order for ActiveRecord now always concatenate nested calls. Use reorder if you want the original order to be overwritten *Santiago Pastorino*
878
879 * PostgreSQL: ensure the database time zone matches Ruby's time zone #4895 *Aaron Patterson*
880
881 * Fixed that ActiveRecord::Base.compute_type would swallow NoMethodError #4751 *Andrew Bloomgarden, Andrew White*
882
883 * Add index length support for MySQL. #1852 *Emili Parreno, Pratik Naik*
884
885 Example:
886
887 add_index(:accounts, :name, :name => 'by_name', :length => 10)
888 => CREATE INDEX by_name ON accounts(name(10))
889
890 add_index(:accounts, [:name, :surname], :name => 'by_name_surname', :length => {:name => 10, :surname => 15})
891 => CREATE INDEX by_name_surname ON accounts(name(10), surname(15))
892
893 * find_or_create_by_attr(value, ...) works when attr is protected. #4457 *Santiago Pastorino, Marc-André Lafortune*
894
895 * New callbacks: after_commit and after_rollback. Do expensive operations like image thumbnailing after_commit instead of after_save. #2991 *Brian Durand*
896
897 * 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*
898
899 * 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*
900
901 * PostgreSQL: drop support for old postgres driver. Use pg 0.9.0 or later. *Jeremy Kemper*
902
903 * Observers can prevent records from saving by returning false, just like before_save and friends. #4087 *Mislav Marohnić*
904
905 * Add Relation extensions. *Pratik Naik*
906
907 users = User.where(:admin => true).extending(User::AdminPowers)
908
909 latest_users = User.order('created_at DESC') do
910 def posts_count
911 Post.count(:user_id => to_a.map(&:id))
912 end
913 end
914
915 * To prefix the table names of all models in a module, define self.table_name_prefix on the module. #4032 *Andrew White*
916
917 * 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*
918
919 * 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*
920
921 * Allow relations to be used as scope.
922
923 class Item
924 scope :red, where(:colour => 'red')
925 end
926
927 Item.red.limit(10) # Ten red items
928
929 * Rename named_scope to scope. *Pratik Naik*
930
931 * Changed ActiveRecord::Base.store_full_sti_class to be true by default reflecting the previously announced Rails 3 default *DHH*
932
933 * Add Relation#except. *Pratik Naik*
934
935 one_red_item = Item.where(:colour => 'red').limit(1)
936 all_items = one_red_item.except(:where, :limit)
937
938 * Add Relation#delete_all. *Pratik Naik*
939
940 Item.where(:colour => 'red').delete_all
941
942 * Add Model.having and Relation#having. *Pratik Naik*
943
944 Developer.group("salary").having("sum(salary) > 10000").select("salary")
945
946 * Add Relation#count. *Pratik Naik*
947
948 legends = People.where("age > 100")
949 legends.count
950 legends.count(:age, :distinct => true)
951 legends.select('id').count
952
953 * Add Model.readonly and association_collection#readonly finder method. *Pratik Naik*
954
955 Post.readonly.to_a # Load all posts in readonly mode
956 @user.items.readonly(false).to_a # Load all the user items in writable mode
957
958 * Add .lock finder method *Pratik Naik*
959
960 User.lock.where(:name => 'lifo').to_a
961
962 old_items = Item.where("age > 100")
963 old_items.lock.each {|i| .. }
964

966
967 user = User.scoped
968 user.select('*').from('users, items')
969
970 * Add relation.destroy_all *Pratik Naik*
971
972 old_items = Item.where("age > 100")

976
977 red_items = Item.where(:colours => 'red')
978 red_items.exists?
979 red_items.exists?(1)
980
981 * Add find(ids) to relations. *Pratik Naik*
982
983 old_users = User.order("age DESC")
984 old_users.find(1)
985 old_users.find(1, 2, 3)
986
987 * Add new finder methods to association collection. *Pratik Naik*
988
989 class User < ActiveRecord::Base
990 has_many :items
991 end
992
993 user = User.first
994 user.items.where(:items => {:colour => 'red'})
995 user.items.select('items.id')
996
997 * Add relation.reload to force reloading the records. *Pratik Naik*
998
999 topics = Topic.scoped
1000 topics.to_a # force load
1001 topics.first # returns a cached record
1002 topics.reload
1003 topics.first # Fetches a new record from the database
1004
1005 * Rename Model.conditions and relation.conditions to .where. *Pratik Naik*
1006
1007 Before :
1008 User.conditions(:name => 'lifo')
1009 User.select('id').conditions(["age > ?", 21])
1010

1020 posts.each {|p| puts p.id } # Fires "select id from posts order by name"
1021
1022 * Model.scoped now returns a relation if invoked without any arguments. *Pratik Naik*
1023
1024 Example :
1025
1026 posts = Post.scoped
1027 posts.size # Fires "select count(*) from posts" and returns the count
1028 posts.each {|p| puts p.name } # Fires "select * from posts" and loads post objects
1029
1030 * Association inverses for belongs_to, has_one, and has_many. Optimization to reduce database queries. #3533 *Murray Steele*
1031
1032 # post.comments sets each comment's post without needing to :include
1033 class Post < ActiveRecord::Base
1034 has_many :comments, :inverse_of => :post
1035 end
1036
1037 * MySQL: add_ and change_column support positioning. #3286 *Ben Marini*

1042
1043 * PostgreSQL: XML datatype support. #1874 *Leonardo Borges*
1044
1045 * 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*
1046
1047 * SQLite: drop support for 'dbfile' option in favor of 'database.' #2363 *Paul Hinze, Jeremy Kemper*
1048
1049 * Added :primary_key option to belongs_to associations. #765 *Szymon Nowak, Philip Hallstrom, Noel Rocha*
1050 # employees.company_name references companies.name
1051 Employee.belongs_to :company, :primary_key => 'name', :foreign_key => 'company_name'
1052
1053 * Implement #many? for NamedScope and AssociationCollection using #size. #1500 *Chris Kampmeier*

1090
1091 class Person < ActiveRecord::Base
1092 default_scope :order => 'last_name, first_name'
1093 end
1094
1095 class Company < ActiveRecord::Base
1096 has_many :people
1097 end
1098

1146
1147 * Allow conditions on multiple tables to be specified using hash. [Pratik Naik]. Example:
1148
1149 User.all :joins => :items, :conditions => { :age => 10, :items => { :color => 'black' } }
1150 Item.first :conditions => { :items => { :color => 'red' } }

1229
1230 Post.find(1).to_json # => {"title": ...}
1231 config.active_record.include_root_in_json = true
1232 Post.find(1).to_json # => {"post": {"title": ...}}

1235
1236 * PostgreSQL: create_ and drop_database support. #9042 *ez, pedz, Nick Sieger*
1237
1238 * Ensure that validates_uniqueness_of works with with_scope. Closes #9235. *Nik Wakelin, cavalle*
1239
1240 * Partial updates include only unsaved attributes. Off by default; set YourClass.partial_updates = true to enable. *Jeremy Kemper*

1245
1246 * Track changes to unsaved attributes. *Jeremy Kemper*
1247

Also added rake db:migrate:up/down to apply individual migrations that may need to be run when you merge branches #11458 *John Barnette*
1249
1250 * Fixed that has_many :through would ignore the hash conditions #11447 *Emilio Tagua*
1251
1252 * Fix issue where the :uniq option of a has_many :through association is ignored when find(:all) is called. Closes #9407 *cavalle*
1253
1254 * Fix duplicate table alias error when including an association with a has_many :through association on the same join table. Closes #7310 *cavalle*

1482
1483 * Assigning an instance of a foreign class to a composed_of aggregate calls an optional conversion block. Refactor and simplify composed_of implementation. #6322 *brandon, Chris Cruft*
1484
1485 * Assigning nil to a composed_of aggregate also sets its immediate value to nil. #9843 *Chris Cruft*

1539 belongs_to :article, :counter_cache => :comments_count
1540 end
1541
1542 class Article < ActiveRecord::Base
1543 attr_readonly :approved_comments_count

1562 * Added ActiveRecord::Base#to_json/from_json *David Heinemeier Hansson, Cheah Chu Yeow*
1563

1567 Person.new.from_xml(xml).name # => "David"
1568
1569 * Define dynamic finders as real methods after first usage. *bscofield*

1581 * Extract Firebird, FrontBase, and OpenBase adapters into gems. #9508, #9509, #9510 *Jeremy Kemper*
1582
1583 * RubyGem database adapters: expects a gem named activerecord-<database>-adapter with active_record/connection_adapters/<database>_adapter.rb in its load path. *Jeremy Kemper*
1584
1585 * Fixed that altering join tables in migrations would fail w/ sqlite3 #7453 *TimoMihaljov/brandon*

1607 For more information see: http://dev.rubyonrails.org/ticket/8049
1608
1609 * Don't clobber includes passed to has_many.count *Jack Danger Canty*
1610
1611 * Make sure has_many uses :include when counting *Jack Danger Canty*
1612
1613 * Change the implementation of ActiveRecord's attribute reader and writer methods *Michael Koziarski*
1614 - 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.
1615 * Perform a deep #dup on query cache results so that modifying activerecord attributes does not modify the cached attributes. *Rick Olson*
1616
1617 \# Ensure that has_many :through associations use a count query instead of loading the target when #size is called. Closes #8800 [Pratik Naik]
1618 * Added :unless clause to validations #8003 [monki]. Example:
1619
1620 def using_open_id?
1621 !identity_url.blank?
1622 end
1623
1624 validates_presence_of :identity_url, :if => using_open_id?
1625 validates_presence_of :username, :unless => using_open_id?
1626 validates_presence_of :password, :unless => using_open_id?
1627
1628 * Fix #count on a has_many :through association so that it recognizes the :uniq option. Closes #8801 *Pratik Naik*
1629
1630 * Fix and properly document/test count(column_name) usage. Closes #8999 *Pratik Naik*
1631
1632 * Remove deprecated count(conditions=nil, joins=nil) usage. Closes #8993 *Pratik Naik*
1633
1634 * Change belongs_to so that the foreign_key assumption is taken from the association name, not the class name. Closes #8992 *Josh Susser*
1635
1636 OLD
1637 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is user_id
1638
1639 NEW
1640 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is visitor_id
1641
1642 * Remove spurious tests from deprecated_associations_test, most of these aren't deprecated, and are duplicated in associations_test. Closes #8987 *Pratik Naik*
1643
1644 * Make create! on a has_many :through association return the association object. Not the collection. Closes #8786 *Pratik Naik*
1645
1646 * Move from select * to select tablename.* to avoid clobbering IDs. Closes #8889 *dasil003*
1647
1648 * Don't call unsupported methods on associated objects when using :include, :method with to_xml #7307, *Manfred Stienstra, jwilger*
1649
1650 * Define collection singular ids method for has_many :through associations. #8763 *Pratik Naik*

1652 * Array attribute conditions work with proxied association collections. #8318 *Kamal Fariz Mahyuddin, theamazingrando*
1653
1654 * Fix polymorphic has_one associations declared in an abstract class. #8638 *Pratik Naik, Dax Huiberts*
1655
1656 * Fixed validates_associated should not stop on the first error. #4276 *mrj, Manfred Stienstra, Josh Peek*

1673
1674 * Quickref for association methods. #7723 *marclove, Mindsweeper*
1675
1676 * Calculations: return nil average instead of 0 when there are no rows to average. #8298 *davidw*
1677
1678 * acts_as_nested_set: direct_children is sorted correctly. #4761 *Josh Peek, rails@33lc0.net*
1679
1680 * Raise an exception if both attr_protected and attr_accessible are declared. #8507 *stellsmi*
1681
1682 * SQLite, MySQL, PostgreSQL, Oracle: quote column names in column migration SQL statements. #8466 *marclove, lorenjohnson*
1683
1684 * Allow nil serialized attributes with a set class constraint. #7293 *sandofsky*
1685
1686 * Oracle: support binary fixtures. #7987 *Michael Schoen*
1687
1688 * Fixtures: pull fixture insertion into the database adapters. #7987 *Michael Schoen*

1702 * Migrations: add_column supports custom column types. #7742 *jsgarvin, Theory*
1703
1704 * Load database adapters on demand. Eliminates config.connection_adapters and RAILS_CONNECTION_ADAPTERS. Add your lib directory to the $LOAD_PATH and put your custom adapter in lib/active_record/connection_adapters/adaptername_adapter.rb. This way you can provide custom adapters as plugins or gems without modifying Rails. *Jeremy Kemper*
1705
1706 * Ensure that associations with :dependent => :delete_all respect :conditions option. Closes #8034 *Jack Danger Canty, Josh Peek, Rick Olson*
1707
1708 * belongs_to assignment creates a new proxy rather than modifying its target in-place. #8412 *mmangino@elevatedrails.com*

1727
1728 * Enhance documentation for increment_counter and decrement_counter. *fearoffish*
1729
1730 * Provide brief introduction to what optimistic locking is. *fearoffish*
1731
1732 * Add documentation for :encoding option to mysql adapter. *marclove*
1733
1734 * Added short-hand declaration style to migrations (inspiration from Sexy Migrations, http://errtheblog.com/post/2381) [David Heinemeier Hansson]. Example:
1735
1736 create_table "products" do |t|
1737 t.column "shop_id", :integer
1738 t.column "creator_id", :integer
1739 t.column "name", :string, :default => "Untitled"
1740 t.column "value", :string, :default => "Untitled"
1741 t.column "created_at", :datetime
1742 t.column "updated_at", :datetime
1743 end
1744
1745 ...can now be written as:
1746
1747 create_table :products do |t|
1748 t.integer :shop_id, :creator_id
1749 t.string :name, :value, :default => "Untitled"
1750 t.timestamps
1751 end
1752
1753 * 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*
1754
1755 * Improve performance of calling .create on has_many :through associations. *evan*
1756
1757 * Improved cloning performance by relying less on exception raising #8159 *Blaine*
1758
1759 * Added ActiveRecord::Base.inspect to return a column-view like #<Post id:integer, title:string, body:text> *David Heinemeier Hansson*
1760
1761 * Added yielding of Builder instance for ActiveRecord::Base#to_xml calls *David Heinemeier Hansson*
1762
1763 * Small additions and fixes for ActiveRecord documentation. Closes #7342 *Jeremy McAnally*
1764
1765 * Add helpful debugging info to the ActiveRecord::StatementInvalid exception in ActiveRecord::ConnectionAdapters::SqliteAdapter#table_structure. Closes #7925. *court3nay*
1766
1767 * SQLite: binary escaping works with $KCODE='u'. #7862 *tsuka*
1768
1769 * Base#to_xml supports serialized attributes. #7502 *jonathan*
1770
1771 * Base.update_all :order and :limit options. Useful for MySQL updates that must be ordered to avoid violating unique constraints. *Jeremy Kemper*
1772
1773 * 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*
1774
1775 * 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*
1776
1777 * 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*
1778
1779 * 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*
1780
1781 * Allow a polymorphic :source for has_many :through associations. Closes #7143 *protocool*
1782

1788
1789 * Fixtures: fix YAML ordered map support. #2665 *Manuel Holtgrewe, nfbuckley*
1790
1791 * DateTimes assume the default timezone. #7764 *Geoff Buesing*
1792
1793 * Sybase: hide timestamp columns since they're inherently read-only. #7716 *Mike Joyce*
1794
1795 * Oracle: overflow Time to DateTime. #7718 *Michael Schoen*

1799 * Fix has_many :through << with custom foreign keys. #6466, #7153 *naffis, Rich Collins*
1800
1801 * Test DateTime native type in migrations, including an edge case with dates
1802 during calendar reform. #7649, #7724 [fedot, Geoff Buesing]
1803 * SQLServer: correctly schema-dump tables with no indexes or descending indexes. #7333, #7703 *Jakob Skjerning, Tom Ward*
1804

1806
1807 * Added fixtures :all as a way of loading all fixtures in the fixture directory at once #7214 *Manfred Stienstra*
1808
1809 * Added database connection as a yield parameter to ActiveRecord::Base.transaction so you can manually rollback [David Heinemeier Hansson]. Example:
1810
1811 transaction do |transaction|
1812 david.withdrawal(100)
1813 mary.deposit(100)
1814 transaction.rollback! # rolls back the transaction that was otherwise going to be successful

1818
1819 * 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*
1820 Task.cache { Task.find(1); Task.find(1) } # => 1 query
1821
1822 * 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*

1831
1832 * MySQL: SET SQL_AUTO_IS_NULL=0 so 'where id is null' doesn't select the last inserted id. #6778 *Jonathan Viney, timc*
1833
1834 * Use Date#to_s(:db) for quoted dates. #7411 *Michael Schoen*
1835
1836 * Don't create instance writer methods for class attributes. Closes #7401 *Rick Olson*
1837
1838 * Docs: validations examples. #7343 *zackchandler*
1839
1840 * Add missing tests ensuring callbacks work with class inheritance. Closes #7339 *sandofsky*
1841
1842 * Fixtures use the table name and connection from set_fixture_class. #7330 *Anthony Eden*
1843
1844 * Remove useless code in #attribute_present? since 0 != blank?. Closes #7249 *Josh Susser*

1854 * Make sure sqlite3 driver closes open connections on disconnect *Rob Rasmussen*
1855
1856 * [DOC] clear up some ambiguity with the way has_and_belongs_to_many creates the default join table name. #7072 *Jeremy McAnally*
1857
1858 * change_column accepts :default => nil. Skip column options for primary keys. #6956, #7048 *Dan Manges, Jeremy Kemper*
1859
1860 * 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*
1861
1862 * Oracle: create_table takes a :sequence_name option to override the 'tablename_seq' default. #7000 *Michael Schoen*
1863
1864 * MySQL: retain SSL settings on reconnect. #6976 *randyv2*
1865
1866 * Apply scoping during initialize instead of create. Fixes setting of foreign key when using find_or_initialize_by with scoping. *Cody Fauser*
1867
1868 * SQLServer: handle [quoted] table names. #6635 *rrich*
1869
1870 * acts_as_nested_set works with single-table inheritance. #6030 *Josh Susser*

1875 Student.find(:all, :conditions => { :grade => 9..12 })
1876
1877 * Fix the Oracle adapter for serialized attributes stored in CLOBs. Closes #6825 *mschoen, tdfowler*
1878
1879 * [DOCS] Apply more documentation for ActiveRecord Reflection. Closes #4055 *Robby Russell*

1888
1889 * Oracle: fix connection reset failure. #6846 *leonlleslie*
1890
1891 * Subclass instantiation doesn't try to explicitly require the corresponding subclass. #6840 *leei, Jeremy Kemper*
1892
1893 * 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*
1894
1895 * 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*
1896
1897 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
1898
1899 * Add AssociationCollection#create! to be consistent with AssociationCollection#create when dealing with a foreign key that is a protected attribute *Cody Fauser*
1900
1901 * 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*
1902
1903 * Change fixture_path to a class inheritable accessor allowing test cases to have their own custom set of fixtures. #6672 *Zach Dennis*
1904
1905 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
1906
1907 * Simplify query_attribute by typecasting the attribute value and checking whether it's nil, false, zero or blank. #6659 *Jonathan Viney*
1908
1909 * 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*
1910
1911 * Run validations in the order they were declared. #6657 *obrie*
1912
1913 * 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*
1914
1915 * Simplify association proxy implementation by factoring construct_scope out of method_missing. #6643 *martin*
1916
1917 * Oracle: automatically detect the primary key. #6594 *vesaria, Michael Schoen*

1934 find(:all, :conditions => { :topic_id => [1, 2, 3], :last_read => nil }
1935
1936 * 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*
1937
1938 * SQLite: fix calculations workaround, remove count(distinct) query rewrite, cleanup test connection scripts. *Jeremy Kemper*
1939

1949
1950 * Make add_column use the options hash with the Sqlite Adapter. Closes #6464 *obrie*
1951
1952 * Document other options available to migration's add_column. #6419 *grg*
1953
1954 * MySQL: all_hashes compatibility with old MysqlRes class. #6429, #6601 *Jeremy Kemper*
1955
1956 * Fix has_many :through to add the appropriate conditions when going through an association using STI. Closes #5783. *Jonathan Viney*

1963
1964 * Add #delete support to has_many :through associations. Closes #6049 *Martin Landers*
1965
1966 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
1967
1968 * 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*

1975
1976 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
1977
1978 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
1979
1980 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
1981
1982 * 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*
1983
1984 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
1985

2001
2002 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
2003
2004 * 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*
2005
2006 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
2007
2008 * Document validates_presences_of behavior with booleans: you probably want validates_inclusion_of :attr, :in => [true, false]. #2253 *Bob Silva*
2009
2010 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
2011
2012 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
2013
2014 * Deprecation: update docs. #5998 *Jakob Skjerning, Kevin Clark*
2015
2016 * Add some XmlSerialization tests for ActiveRecord *Rick Olson*
2017
2018 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
2019
2020 * Tighten rescue clauses. #5985 *james@grayproductions.net*
2021
2022 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
2023
2024 * 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*
2025
2026 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
2027
2028 * 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*
2029
2030 * SQLServer: fix eager association test. #5901 *Tom Ward*
2031

2039
2040 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2041
2042 * 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*
2043
2044 * 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*
2045
2046 # Create a tagging to associate the post and tag.
2047 post.tags << Tag.find_by_name('old')
2048 post.tags.create! :name => 'general'
2049
2050 # Would have been:
2051 post.taggings.create!(:tag => Tag.find_by_name('finally')
2052 transaction do
2053 post.taggings.create!(:tag => Tag.create!(:name => 'general'))

2061 Example: Invoice::Lineitem is given table name invoice_lineitems
2062
2063 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2064 # people_active_last_name_index, people_active_deactivated_at_index
2065 add_index :people, [:active, :last_name]
2066 add_index :people, [:active, :deactivated_at]
2067 remove_index :people, [:active, :last_name]
2068 remove_index :people, [:active, :deactivated_at]
2069
2070 WARNING: backward-incompatibility. Multicolumn indexes created before this
2071 revision were named using the first column name only. Now they're uniquely
2072 named using all indexed columns.
2073
2074 To remove an old multicolumn index, remove_index :table_name, :first_column
2075

2090 * Add documentation for how to disable timestamps on a per model basis. Closes #5684. *matt@mattmargolis.net Marcel Molina Jr.*
2091
2092 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*

2166 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2167
2168 * 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*
2169 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2170 Person.transaction do
2171 # select * from people where id=1 for update
2172 person = Person.find(1, :lock => true)
2173 person.visits += 1
2174 person.save!
2175 end
2176
2177 * 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*
2178
2179 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2180
2181 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2182
2183 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2184
2185 * 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*
2186
2187 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2188
2189 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2190
2191 ...is the same as:
2192 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2193
2194 This makes it easier to pass in the options from a form or otherwise outside.
2195

2206
2207 * 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*
2208
2209 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
2210
2211 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
2212
2213 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
2214 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
2215 Foo.find(:first, :conditions => ['bar_id = ?', bar])
2216
2217 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
2218
2219 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
2220
2221 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*
2222

2224 Closes #4433 *Josh Susser*
2225

2233
2234 * Added :allow_nil option for aggregations #5091 *Ian White*
2235
2236 * Fix Oracle boolean support and tests. Closes #5139. *Michael Schoen*
2237
2238 * 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*
2239
2240 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2241
2242 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2243
2244 * 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*

2304
2305 * Ensure that Associations#include_eager_conditions? checks both scoped and explicit conditions *Rick Olson*
2306
2307 * Associations#select_limited_ids_list adds the ORDER BY columns to the SELECT DISTINCT List for postgresql. *Rick Olson*

2317 end
2318
2319 * Allow multiple association extensions with :extend option (closes #4666) *Josh Susser*
2320
2321 class Account < ActiveRecord::Base
2322 has_many :people, :extend => [FindOrCreateByNameExtension, FindRecentExtension]
2323 end
2324
2325 *1.15.3* (March 12th, 2007)

2334
2335
2336 ## 1.15.2 (February 5th, 2007) ##
2337

2339 Student.find(:all, :conditions => { :grade => 9..12 })
2340
2341 * Don't create instance writer methods for class attributes. *Rick Olson*
2342
2343 * 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*
2344
2345 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*
2346
2347 * 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*
2348
2349 * MySQL: SET SQL_AUTO_IS_NULL=0 so 'where id is null' doesn't select the last inserted id. #6778 *Jonathan Viney, timc*

2364
2365 * change_column accepts :default => nil. Skip column options for primary keys. #6956, #7048 *Dan Manges, Jeremy Kemper*
2366
2367 * 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*

2388
2389 * Subclass instantiation doesn't try to explicitly require the corresponding subclass. #6840 *leei, Jeremy Kemper*
2390
2391 * 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*
2392
2393 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
2394
2395 * Support nil and Array in :conditions => { attr => value } hashes. #6548 *Assaf, Jeremy Kemper*

2397
2398 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
2399

2439
2440 * 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*
2441
2442 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*

2447
2448 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
2449
2450 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
2451
2452 * 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*
2453
2454 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
2455
2456 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*

2467
2468 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
2469
2470 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
2471
2472 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
2473
2474 * 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*
2475
2476 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
2477
2478 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
2479
2480 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
2481
2482 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
2483
2484 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
2485
2486 * 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*
2487
2488 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
2489
2490 * 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*
2491
2492 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
2493
2494 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
2495
2496 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*
2497
2498 * MySQL: update test schema for MySQL 5 strict mode. #5861 *Tom Ward*
2499
2500 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2501
2502 * 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*
2503
2504 * 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*
2505
2506 # Create a tagging to associate the post and tag.
2507 post.tags << Tag.find_by_name('old')
2508 post.tags.create! :name => 'general'
2509
2510 # Would have been:
2511 post.taggings.create!(:tag => Tag.find_by_name('finally')
2512 transaction do
2513 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
2514 end

2518 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
2519
2520 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
2521 Example: Invoice::Lineitem is given table name invoice_lineitems
2522
2523 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2524 # people_active_last_name_index, people_active_deactivated_at_index
2525 add_index :people, [:active, :last_name]
2526 add_index :people, [:active, :deactivated_at]
2527 remove_index :people, [:active, :last_name]
2528 remove_index :people, [:active, :deactivated_at]
2529
2530 WARNING: backward-incompatibility. Multicolumn indexes created before this
2531 revision were named using the first column name only. Now they're uniquely
2532 named using all indexed columns.
2533
2534 To remove an old multicolumn index, remove_index :table_name, :first_column
2535

2539
2540 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
2541

2543
2544 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
2545
2546 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
2547
2548 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
2549
2550 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
2551
2552 * Formally deprecate the deprecated finders. *Michael Koziarski*
2553
2554 * Formally deprecate rich associations. *Michael Koziarski*
2555
2556 * Fixed that default timezones for new / initialize should uphold utc setting #5709 *daniluk@yahoo.com*
2557
2558 * Fix announcement of very long migration names. #5722 *blake@near-time.com*
2559
2560 * The exists? class method should treat a string argument as an id rather than as conditions. #5698 *jeremy@planetargon.com*
2561
2562 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
2563
2564 * Added support for conditions on Base.exists? #5689 [Josh Peek]. Examples:
2565
2566 assert (Topic.exists?(:author_name => "David"))
2567 assert (Topic.exists?(:author_name => "Mary", :approved => true))
2568 assert (Topic.exists?(["parent_id = ?", 1]))
2569
2570 * Schema dumper quotes date :default values. *Dave Thomas*
2571
2572 * Calculate sum with SQL, not Enumerable on HasManyThrough Associations. *Dan Peterson*
2573
2574 * Factor the attribute#{suffix} methods out of method_missing for easier extension. *Jeremy Kemper*
2575
2576 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
2577
2578 * Allow #count through a has_many association to accept :include. *Dan Peterson*
2579
2580 * create_table rdoc: suggest :id => false for habtm join tables. *Zed Shaw*
2581
2582 * PostgreSQL: return array fields as strings. #4664 *Robby Russell*
2583
2584 * 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*
2585
2586 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2587
2588 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2589
2590 * 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*
2591
2592 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*
2593
2594 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2595
2596 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2597
2598 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2599
2600 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2601
2602 * 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*
2603
2604 * 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*
2605
2606 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2607
2608 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2609
2610 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2611
2612 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2613
2614 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2615
2616 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2617
2618 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2619
2620 * 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*
2621 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2622 Person.transaction do
2623 # select * from people where id=1 for update
2624 person = Person.find(1, :lock => true)
2625 person.visits += 1
2626 person.save!
2627 end
2628
2629 * 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*
2630
2631 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2632
2633 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2634
2635 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2636
2637 * 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*
2638
2639 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2640
2641 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2642
2643 ...is the same as:
2644 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2645
2646 This makes it easier to pass in the options from a form or otherwise outside.
2647
2648
2649 * Fixed issues with BLOB limits, charsets, and booleans for Firebird #5194, #5191, #5189 *kennethkunz@gmail.com*
2650
2651 * Fixed usage of :limit and with_scope when the association in scope is a 1:m #5208 *alex@purefiction.net*
2652
2653 * Fixed migration trouble with SQLite when NOT NULL is used in the new definition #5215 *greg@lapcominc.com*
2654
2655 * Fixed problems with eager loading and counting on SQL Server #5212 *kajism@yahoo.com*
2656
2657 * Fixed that count distinct should use the selected column even when using :include #5251 *anna@wota.jp*
2658
2659 * 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*
2660
2661 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
2662
2663 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
2664
2665 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
2666 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
2667 Foo.find(:first, :conditions => ['bar_id = ?', bar])
2668
2669 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
2670
2671 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
2672
2673 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*
2674
2675 * Provide Association Extensions access to the instance that the association is being accessed from.
2676 Closes #4433 *Josh Susser*
2677
2678 * Update OpenBase adaterp's maintainer's email address. Closes #5176. *Derrick Spell*
2679
2680 * Add a quick note about :select and eagerly included associations. *Rick Olson*
2681
2682 * Add docs for the :as option in has_one associations. Closes #5144 *cdcarter@gmail.com*
2683
2684 * Fixed that has_many collections shouldn't load the entire association to do build or create *David Heinemeier Hansson*
2685
2686 * Added :allow_nil option for aggregations #5091 *Ian White*
2687
2688 * Fix Oracle boolean support and tests. Closes #5139. *Michael Schoen*
2689
2690 * 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*
2691
2692 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2693
2694 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2695
2696 * 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*

2709
2710 * Add support for FrontBase (http://www.frontbase.com/) with a new adapter thanks to the hard work of one Mike Laster. Closes #4093. *mlaster@metavillage.com*
2711
2712 * Add warning about the proper way to validate the presence of a foreign key. Closes #4147. *Francois Beausoleil <francois.beausoleil@gmail.com>*

2755 class Account < ActiveRecord::Base
2756 has_many :people, :extend => [FindOrCreateByNameExtension, FindRecentExtension]
2757 end
2758
2759
2760 ## 1.14.4 (August 8th, 2006) ##

2783
2784 * Fixed calculations for the Oracle Adapter (closes #4626) *Michael Schoen*
2785
2786
2787 ## 1.14.1 (April 6th, 2006) ##

2789 * Fix type_name_with_module to handle type names that begin with '::'. Closes #4614. *Nicholas Seckar*
2790
2791 * Fixed that that multiparameter assignment doesn't work with aggregations (closes #4620) *Lars Pind*
2792
2793 * Enable Limit/Offset in Calculations (closes #4558) *lmarlow*
2794
2795 * Fixed that loading including associations returns all results if Load IDs For Limited Eager Loading returns none (closes #4528) *Rick Olson*
2796
2797 * Fixed HasManyAssociation#find bugs when :finder_sql is set #4600 *lagroue@free.fr*
2798
2799 * Allow AR::Base#respond_to? to behave when @attributes is nil *Ryan Davis*
2800
2801 * Support eager includes when going through a polymorphic has_many association. *Rick Olson*
2802
2803 * Added support for eagerly including polymorphic has_one associations. (closes #4525) *Rick Olson*
2804
2805 class Post < ActiveRecord::Base
2806 has_one :tagging, :as => :taggable
2807 end
2808
2809 Post.find :all, :include => :tagging
2810
2811 * Added descriptive error messages for invalid has_many :through associations: going through :has_one or :has_and_belongs_to_many *Rick Olson*
2812
2813 * Added support for going through a polymorphic has_many association: (closes #4401) *Rick Olson*
2814
2815 class PhotoCollection < ActiveRecord::Base
2816 has_many :photos, :as => :photographic
2817 belongs_to :firm
2818 end
2819
2820 class Firm < ActiveRecord::Base
2821 has_many :photo_collections
2822 has_many :photos, :through => :photo_collections
2823 end
2824
2825 * Multiple fixes and optimizations in PostgreSQL adapter, allowing ruby-postgres gem to work properly. *ruben.nine@gmail.com*
2826
2827 * Fixed that AssociationCollection#delete_all should work even if the records of the association are not loaded yet. *Florian Weber*
2828
2829 * Changed those private ActiveRecord methods to take optional third argument :auto instead of nil for performance optimizations. (closes #4456) *Stefan*
2830
2831 * Private ActiveRecord methods add_limit!, add_joins!, and add_conditions! take an OPTIONAL third argument 'scope' (closes #4456) *Rick Olson*
2832
2833 * DEPRECATED: Using additional attributes on has_and_belongs_to_many associations. Instead upgrade your association to be a real join model *David Heinemeier Hansson*
2834
2835 * Fixed that records returned from has_and_belongs_to_many associations with additional attributes should be marked as read only (fixes #4512) *David Heinemeier Hansson*
2836
2837 * Do not implicitly mark recordss of has_many :through as readonly but do mark habtm records as readonly (eventually only on join tables without rich attributes). *Marcel Mollina Jr.*
2838
2839 * Fixed broken OCIAdapter #4457 *Michael Schoen*
2840
2841
2842 ## 1.14.0 (March 27th, 2006) ##
2843
2844 * Replace 'rescue Object' with a finer grained rescue. Closes #4431. *Nicholas Seckar*
2845
2846 * Fixed eager loading so that an aliased table cannot clash with a has_and_belongs_to_many join table *Rick Olson*
2847
2848 * Add support for :include to with_scope *andrew@redlinesoftware.com*
2849
2850 * Support the use of public synonyms with the Oracle adapter; required ruby-oci8 v0.1.14 #4390 *Michael Schoen*
2851
2852 * Change periods (.) in table aliases to _'s. Closes #4251 *jeff@ministrycentered.com*
2853
2854 * Changed has_and_belongs_to_many join to INNER JOIN for Mysql 3.23.x. Closes #4348 *Rick Olson*
2855
2856 * Fixed issue that kept :select options from being scoped *Rick Olson*
2857
2858 * Fixed db_schema_import when binary types are present #3101 *David Heinemeier Hansson*
2859
2860 * Fixed that MySQL enums should always be returned as strings #3501 *David Heinemeier Hansson*
2861
2862 * Change has_many :through to use the :source option to specify the source association. :class_name is now ignored. *Rick Olson*
2863
2864 class Connection < ActiveRecord::Base
2865 belongs_to :user
2866 belongs_to :channel
2867 end
2868
2869 class Channel < ActiveRecord::Base
2870 has_many :connections
2871 has_many :contacts, :through => :connections, :class_name => 'User' # OLD
2872 has_many :contacts, :through => :connections, :source => :user # NEW
2873 end
2874
2875 * Fixed DB2 adapter so nullable columns will be determines correctly now and quotes from column default values will be removed #4350 *contact@maik-schmidt.de*
2876
2877 * Allow overriding of find parameters in scoped has_many :through calls *Rick Olson*
2878
2879 In this example, :include => false disables the default eager association from loading. :select changes the standard
2880 select clause. :joins specifies a join that is added to the end of the has_many :through query.
2881
2882 class Post < ActiveRecord::Base
2883 has_many :tags, :through => :taggings, :include => :tagging do
2884 def add_joins_and_select
2885 find :all, :select => 'tags.*, authors.id as author_id', :include => false,
2886 :joins => 'left outer join posts on taggings.taggable_id = posts.id left outer join authors on posts.author_id = authors.id'
2887 end
2888 end
2889 end
2890
2891 * Fixed that schema changes while the database was open would break any connections to an SQLite database (now we reconnect if that error is throw) *David Heinemeier Hansson*
2892
2893 * Don't classify the has_one class when eager loading, it is already singular. Add tests. (closes #4117) *Jonathan Viney*
2894
2895 * Quit ignoring default :include options in has_many :through calls *Mark James*
2896
2897 * Allow has_many :through associations to find the source association by setting a custom class (closes #4307) *Jonathan Viney*
2898
2899 * Eager Loading support added for has_many :through => :has_many associations (see below). *Rick Olson*
2900
2901 * Allow has_many :through to work on has_many associations (closes #3864) [sco@scottraymond.net] Example:
2902
2903 class Firm < ActiveRecord::Base
2904 has_many :clients
2905 has_many :invoices, :through => :clients
2906 end
2907
2908 class Client < ActiveRecord::Base
2909 belongs_to :firm
2910 has_many :invoices
2911 end
2912
2913 class Invoice < ActiveRecord::Base
2914 belongs_to :client
2915 end
2916
2917 * Raise error when trying to select many polymorphic objects with has_many :through or :include (closes #4226) *Josh Susser*
2918
2919 * Fixed has_many :through to include :conditions set on the :through association. closes #4020 *Jonathan Viney*
2920
2921 * Fix that has_many :through honors the foreign key set by the belongs_to association in the join model (closes #4259) *andylien@gmail.com / Rick Olson*
2922
2923 * SQL Server adapter gets some love #4298 *Ryan Tomayko*
2924
2925 * Added OpenBase database adapter that builds on top of the http://www.spice-of-life.net/ruby-openbase/ driver. All functionality except LIMIT/OFFSET is supported #3528 *derrickspell@cdmplus.com*
2926
2927 * Rework table aliasing to account for truncated table aliases. Add smarter table aliasing when doing eager loading of STI associations. This allows you to use the association name in the order/where clause. [Jonathan Viney / Rick Olson] #4108 Example (SpecialComment is using STI):
2928
2929 Author.find(:all, :include => { :posts => :special_comments }, :order => 'special_comments.body')
2930
2931 * Add AbstractAdapter#table_alias_for to create table aliases according to the rules of the current adapter. *Rick Olson*
2932
2933 * Provide access to the underlying database connection through Adapter#raw_connection. Enables the use of db-specific methods without complicating the adapters. #2090 *Michael Koziarski*
2934
2935 * Remove broken attempts at handling columns with a default of 'now()' in the postgresql adapter. #2257 *Michael Koziarski*
2936
2937 * Added connection#current_database that'll return of the current database (only works in MySQL, SQL Server, and Oracle so far -- please help implement for the rest of the adapters) #3663 *Tom Ward*
2938
2939 * Fixed that Migration#execute would have the table name prefix appended to its query #4110 *mark.imbriaco@pobox.com*
2940
2941 * Make all tinyint(1) variants act like boolean in mysql (tinyint(1) unsigned, etc.) *Jamis Buck*
2942
2943 * Use association's :conditions when eager loading. [Jeremy Evans] #4144
2944
2945 * Alias the has_and_belongs_to_many join table on eager includes. #4106 *Jeremy Evans*
2946
2947 This statement would normally error because the projects_developers table is joined twice, and therefore joined_on would be ambiguous.
2948
2949 Developer.find(:all, :include => {:projects => :developers}, :conditions => 'join_project_developers.joined_on IS NOT NULL')
2950
2951 * Oracle adapter gets some love #4230 *Michael Schoen*
2952
2953 * Changes :text to CLOB rather than BLOB [Moses Hohman]
2954 * Fixes an issue with nil numeric length/scales (several)
2955 * Implements support for XMLTYPE columns [wilig / Kubo Takehiro]
2956 * Tweaks a unit test to get it all green again
2957 * Adds support for #current_database
2958
2959 * Added Base.abstract_class? that marks whi
