6764b7b @spastorino Add missing CHANGELOG entries
spastorino authored
8 * Do not eager load AR session store. ActiveRecord::SessionStore depends on the abstract store in Action Pack. Eager loading this class would break client code that eager loads Active Record standalone. Fixes #7160 *Xavier Noria*

10 * Do not set RAILS_ENV to "development" when using `db:test:prepare` and related rake tasks.

44
959fb8e @jonleighton Revert "Perf: Don't load the association for #delete_all."
jonleighton authored
45 * Revert earlier 'perf fix' (see 3.2.4 changelog / GH #6289). This
46 change introduced a regression (GH #6609). assoc.clear and
47 assoc.delete_all have loaded the association before doing the delete
48 since at least Rails 2.3. Doing the delete without loading the
49 records means that the `before_remove` and `after_remove` callbacks do
50 not get invoked. Therefore, this change was less a fix a more an
51 optimisation, which should only have gone into master.

117 * Added a `with_lock` method to ActiveRecord objects, which starts
118 a transaction, locks the object (pessimistically) and yields to the block.
119 The method takes one (optional) parameter and passes it to `lock!`.
120

163
164 A new configuration parameter `config.active_record.auto_explain_threshold_in_seconds`

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

jonleighton authored
249 * Allow the :class_name option for associations to take a symbol (:Client) in addition to
250 a string ('Client').
251
252 This is to avoid confusing newbies, and to be consistent with the fact that other options
253 like :foreign_key already allow a symbol or a string.
254
255 *Jon Leighton*
256
257 * In development mode the db:drop task also drops the test database. For symmetry with
258 the db:create task. *Dmitriy Kiriyenko*
259
260 * Added ActiveRecord::Base.store for declaring simple single-column key/value stores *DHH*
261
262 class User < ActiveRecord::Base
263 store :settings, accessors: [ :color, :homepage ]

272 the column already uses a case-insensitive collation. Fixes #561.

276 * Transactional fixtures enlist all active database connections. You can test
277 models on different connections without disabling transactional fixtures.
278
279 *Jeremy Kemper*
280
281 * Add first_or_create, first_or_create!, first_or_initialize methods to Active Record. This is a
282 better approach over the old find_or_create_by dynamic methods because it's clearer which
283 arguments are used to find the record and which are used to create it:

379
380 * CollectionProxy#replace should change the DB records rather than just mutating the array.
381 Fixes #3020.
382
383 *Jon Leighton*
384
385 * LRU cache in mysql and sqlite are now per-process caches.
386
387 * lib/active_record/connection_adapters/mysql_adapter.rb: LRU cache keys are per process id.
388 * lib/active_record/connection_adapters/sqlite_adapter.rb: ditto
389 *Aaron Patterson*
390

392
393 * If multiple parameters are sent representing a date, and some are blank, the
394 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]
395 * ActiveRecord::Base.establish_connection now takes a string that contains
396 a URI that specifies the connection configuration. For example:
397 ActiveRecord::Base.establish_connection 'postgres://localhost/foo'
398
399 * 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.
400
401 So if you were doing this and expecting the second argument to be nil:
402
403 User.find_by_username_and_group("sikachu")
404
405 You'll now get `ArgumentError: wrong number of arguments (1 for 2).` You'll then have to do this:

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

735 * Destroying records via nested attributes works independent of reject_if LH #6006 *Durran Jordan*
736
737 * Delegate any? and many? to Model.scoped for consistency *Andrew White*
738
739 * Quote the ORDER BY clause in batched finds - fixes #6620 *Andrew White*
740
741 * Change exists? so records are not instantiated - fixes #6127. This prevents after_find
742 and after_initialize callbacks being triggered when checking for record existence.
743 *Andrew White*
744
745 * Fix performance bug with attribute accessors which only occurred on Ruby 1.8.7, and ensure we
746 cache type-casted values when the column returned from the db contains non-standard chars.
747 *Jon Leighton*
748
749 * Fix a performance regression introduced here 86acbf1cc050c8fa8c74a10c735e467fb6fd7df8

753 ## Rails 3.0.6 (April 5, 2011) ##
754
755 * Un-deprecate reorder method *Sebastian Martinez*
756
757 * Extensions are applied when calling +except+ or +only+ on relations.
758 Thanks to Iain Hecker.
759
760 * Schemas set in set_table_name are respected by the mysql adapter. LH #5322
761
762 * Fixed a bug when empty? was called on a grouped Relation that wasn't loaded.
763 LH #5829
764
765 * Reapply extensions when using except and only. Thanks Iain Hecker.
766
767 * Binary data is escaped when being inserted to SQLite3 Databases. Thanks
768 Naruse!
769
770
771 ## Rails 3.0.5 (February 26, 2011) ##
772
773 * Model.where(:column => 1).where(:column => 2) will always produce an AND
774 query.
775 *Aaron Patterson*
776
777 * Deprecated support for interpolated association conditions in the form of :conditions => 'foo = #{bar}'.
778
779 Instead, you should use a proc, like so:
780
781 Before:
782
783 has_many :things, :conditions => 'foo = #{bar}'
784
785 After:
786
787 has_many :things, :conditions => proc { "foo = #{bar}" }
788
789 Inside the proc, 'self' is the object which is the owner of the association, unless you are
790 eager loading the association, in which case 'self' is the class which the association is within.
791
792 You can have any "normal" conditions inside the proc, so the following will work too:
793
794 has_many :things, :conditions => proc { ["foo = ?", bar] }
795
796 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
797 'record' to get the record being inserted or deleted. This is now passed as an argument to
798 the proc.
799
800 *Jon Leighton*
801
802
803 ## Rails 3.0.4 (February 8, 2011) ##
804
805 * Added deprecation warning for has_and_belongs_to_many associations where the join table has
806 additional attributes other than the keys. Access to these attributes is removed in 3.1.
807 Please use has_many :through instead. *Jon Leighton*
808
809
810 ## Rails 3.0.3 (November 16, 2010) ##
811
812 * Support find by class like this: Post.where(:name => Post)
813
814
815 ## Rails 3.0.2 (November 15, 2010) ##
816
817 * Dramatic speed increase (see: http://engineering.attinteractive.com/2010/10/arel-two-point-ohhhhh-yaaaaaa/) *Aaron Patterson*
818
819 * reorder is deprecated in favor of except(:order).order(...) *Santiago Pastorino*
820
821 * except is now AR public API
822
823 Model.order('name').except(:order).order('salary')
824
825 generates:
826
827 SELECT * FROM models ORDER BY salary
828
829 *Santiago Pastorino*
830
831 * The following code:
832
833 Model.limit(10).scoping { Model.count }
834
835 now generates the following SQL:
836
837 SELECT COUNT(*) FROM models LIMIT 10
838
839 This may not return what you want. Instead, you may with to do something
840 like this:
841
842 Model.limit(10).scoping { Model.all.size }
843
844 *Aaron Patterson*
845
846
847 ## Rails 3.0.1 (October 15, 2010) ##
848
849 * Introduce a fix for CVE-2010-3993
850
851
852 ## Rails 3.0.0 (August 29, 2010) ##
853
854 * Changed update_attribute to not run callbacks and update the record directly in the database *Neeraj Singh*
855
856 * Add scoping and unscoped as the syntax to replace the old with_scope and with_exclusive_scope *José Valim*
857
858 * New rake task, db:migrate:status, displays status of migrations #4947 *Kevin Skoglund*
859
860 * select and order for ActiveRecord now always concatenate nested calls. Use reorder if you want the original order to be overwritten *Santiago Pastorino*
861
862 * PostgreSQL: ensure the database time zone matches Ruby's time zone #4895 *Aaron Patterson*
863
864 * Fixed that ActiveRecord::Base.compute_type would swallow NoMethodError #4751 *Andrew Bloomgarden, Andrew White*
865
866 * Add index length support for MySQL. #1852 *Emili Parreno, Pratik Naik*
867
868 Example:
869
870 add_index(:accounts, :name, :name => 'by_name', :length => 10)
871 => CREATE INDEX by_name ON accounts(name(10))
872
873 add_index(:accounts, [:name, :surname], :name => 'by_name_surname', :length => {:name => 10, :surname => 15})
874 => CREATE INDEX by_name_surname ON accounts(name(10), surname(15))
875
876 * find_or_create_by_attr(value, ...) works when attr is protected. #4457 *Santiago Pastorino, Marc-André Lafortune*
877
878 * New callbacks: after_commit and after_rollback. Do expensive operations like image thumbnailing after_commit instead of after_save. #2991 *Brian Durand*
879
880 * 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*
881
882 * 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*
883
884 * PostgreSQL: drop support for old postgres driver. Use pg 0.9.0 or later. *Jeremy Kemper*
885
886 * Observers can prevent records from saving by returning false, just like before_save and friends. #4087 *Mislav Marohnić*
887
888 * Add Relation extensions. *Pratik Naik*
889
890 users = User.where(:admin => true).extending(User::AdminPowers)
891
892 latest_users = User.order('created_at DESC') do
893 def posts_count
894 Post.count(:user_id => to_a.map(&:id))
895 end
896 end
897
898 * To prefix the table names of all models in a module, define self.table_name_prefix on the module. #4032 *Andrew White*
899
900 * 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*
901
902 * 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*
903
904 * Allow relations to be used as scope.
905
906 class Item
907 scope :red, where(:colour => 'red')
908 end
909
910 Item.red.limit(10) # Ten red items
911
912 * Rename named_scope to scope. *Pratik Naik*
913
914 * Changed ActiveRecord::Base.store_full_sti_class to be true by default reflecting the previously announced Rails 3 default *DHH*
915
916 * Add Relation#except. *Pratik Naik*
917
918 one_red_item = Item.where(:colour => 'red').limit(1)
919 all_items = one_red_item.except(:where, :limit)
920
921 * Add Relation#delete_all. *Pratik Naik*
922
923 Item.where(:colour => 'red').delete_all
924
925 * Add Model.having and Relation#having. *Pratik Naik*
926
927 Developer.group("salary").having("sum(salary) > 10000").select("salary")
928
929 * Add Relation#count. *Pratik Naik*
930
931 legends = People.where("age > 100")
932 legends.count
933 legends.count(:age, :distinct => true)
934 legends.select('id').count
935
936 * Add Model.readonly and association_collection#readonly finder method. *Pratik Naik*
937
938 Post.readonly.to_a # Load all posts in readonly mode
939 @user.items.readonly(false).to_a # Load all the user items in writable mode
940
941 * Add .lock finder method *Pratik Naik*
942
943 User.lock.where(:name => 'lifo').to_a
944
945 old_items = Item.where("age > 100")
946 old_items.lock.each {|i| .. }
947
948 * Add Model.from and association_collection#from finder methods *Pratik Naik*
949
950 user = User.scoped
951 user.select('*').from('users, items')
952
953 * Add relation.destroy_all *Pratik Naik*
954
955 old_items = Item.where("age > 100")
956 old_items.destroy_all
957
958 * Add relation.exists? *Pratik Naik*
959
960 red_items = Item.where(:colours => 'red')
961 red_items.exists?
962 red_items.exists?(1)
963
964 * Add find(ids) to relations. *Pratik Naik*
965
966 old_users = User.order("age DESC")
967 old_users.find(1)
968 old_users.find(1, 2, 3)
969
970 * Add new finder methods to association collection. *Pratik Naik*
971
972 class User < ActiveRecord::Base
973 has_many :items
974 end
975
976 user = User.first
977 user.items.where(:items => {:colour => 'red'})
978 user.items.select('items.id')
979
980 * Add relation.reload to force reloading the records. *Pratik Naik*
981
982 topics = Topic.scoped
983 topics.to_a # force load
984 topics.first # returns a cached record
985 topics.reload
986 topics.first # Fetches a new record from the database
987
988 * Rename Model.conditions and relation.conditions to .where. *Pratik Naik*
989
990 Before :
991 User.conditions(:name => 'lifo')
992 User.select('id').conditions(["age > ?", 21])
993
994 Now :
995 User.where(:name => 'lifo')
996 User.select('id').where(["age > ?", 21])
997
998 * Add Model.select/group/order/limit/joins/conditions/preload/eager_load class methods returning a lazy relation. *Pratik Naik*
999
1000 Examples :
1001
1002 posts = Post.select('id).order('name') # Returns a lazy relation
1003 posts.each {|p| puts p.id } # Fires "select id from posts order by name"
1004
1005 * Model.scoped now returns a relation if invoked without any arguments. *Pratik Naik*
1006
1007 Example :
1008
1009 posts = Post.scoped
1010 posts.size # Fires "select count(*) from posts" and returns the count
1011 posts.each {|p| puts p.name } # Fires "select * from posts" and loads post objects
1012
1013 * Association inverses for belongs_to, has_one, and has_many. Optimization to reduce database queries. #3533 *Murray Steele*
1014
1015 # post.comments sets each comment's post without needing to :include
1016 class Post < ActiveRecord::Base
1017 has_many :comments, :inverse_of => :post
1018 end
1019

1025
1026 * PostgreSQL: XML datatype support. #1874 *Leonardo Borges*
1027
1028 * 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*
1029
1030 * SQLite: drop support for 'dbfile' option in favor of 'database.' #2363 *Paul Hinze, Jeremy Kemper*
1031
1032 * Added :primary_key option to belongs_to associations. #765 *Szymon Nowak, Philip Hallstrom, Noel Rocha*
1033 # employees.company_name references companies.name
1034 Employee.belongs_to :company, :primary_key => 'name', :foreign_key => 'company_name'
1035
1036 * Implement #many? for NamedScope and AssociationCollection using #size. #1500 *Chris Kampmeier*

1073
1074 class Person < ActiveRecord::Base
1075 default_scope :order => 'last_name, first_name'
1076 end
1077
1078 class Company < ActiveRecord::Base
1079 has_many :people
1080 end
1081
1082 Person.all # => Person.find(:all, :order => 'last_name, first_name')
1083 Company.find(1).people # => Person.find(:all, :order => 'last_name, first_name', :conditions => { :company_id => 1 })

1129
1130 * Allow conditions on multiple tables to be specified using hash. [Pratik Naik]. Example:
1131
1132 User.all :joins => :items, :conditions => { :age => 10, :items => { :color => 'black' } }
1133 Item.first :conditions => { :items => { :color => 'red' } }

Also added rake db:migrate:up/down to apply individual migrations that may need to be run when you merge branches #11458 *John Barnette*
1232
1233 * Fixed that has_many :through would ignore the hash conditions #11447 *Emilio Tagua*
1234

1236
1237 * Fix duplicate table alias error when including an association with a has_many :through association on the same join table. Closes #7310 *cavalle*

1371
1372 * Fixed that the Query Cache should just be ignored if the database is misconfigured (so that the "About your applications environment" works even before the database has been created) *David Heinemeier Hansson*

1374 * Fixed that the truncation of strings longer than 50 chars should use inspect
1375 so newlines etc are escaped #10385 [Norbert Crombach]
1376 * Fixed that habtm associations should be able to set :select as part of their definition and have that honored *David Heinemeier Hansson*
1377

1545 * Added ActiveRecord::Base#to_json/from_json *David Heinemeier Hansson, Cheah Chu Yeow*
1546

1550 Person.new.from_xml(xml).name # => "David"
1551
1552 * Define dynamic finders as real methods after first usage. *bscofield*

1564 * Extract Firebird, FrontBase, and OpenBase adapters into gems. #9508, #9509, #9510 *Jeremy Kemper*
1565
1566 * RubyGem database adapters: expects a gem named activerecord-<database>-adapter with active_record/connection_adapters/<database>_adapter.rb in its load path. *Jeremy Kemper*
1567
1568 * Fixed that altering join tables in migrations would fail w/ sqlite3 #7453 *TimoMihaljov/brandon*

1590 For more information see: http://dev.rubyonrails.org/ticket/8049
1591
1592 * Don't clobber includes passed to has_many.count *Jack Danger Canty*
1593
1594 * Make sure has_many uses :include when counting *Jack Danger Canty*
1595
1596 * Change the implementation of ActiveRecord's attribute reader and writer methods *Michael Koziarski*
1597 - 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.
1598 * Perform a deep #dup on query cache results so that modifying activerecord attributes does not modify the cached attributes. *Rick Olson*
1599
1600 \# Ensure that has_many :through associations use a count query instead of loading the target when #size is called. Closes #8800 [Pratik Naik]
1601 * Added :unless clause to validations #8003 [monki]. Example:
1602
1603 def using_open_id?
1604 !identity_url.blank?
1605 end
1606
1607 validates_presence_of :identity_url, :if => using_open_id?
1608 validates_presence_of :username, :unless => using_open_id?
1609 validates_presence_of :password, :unless => using_open_id?

1613 * Fix and properly document/test count(column_name) usage. Closes #8999 *Pratik Naik*
1614
1615 * Remove deprecated count(conditions=nil, joins=nil) usage. Closes #8993 *Pratik Naik*
1616
1617 * Change belongs_to so that the foreign_key assumption is taken from the association name, not the class name. Closes #8992 *Josh Susser*
1618
1619 OLD
1620 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is user_id
1621
1622 NEW
1623 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is visitor_id
1624
1625 * Remove spurious tests from deprecated_associations_test, most of these aren't deprecated, and are duplicated in associations_test. Closes #8987 *Pratik Naik*
1626
1627 * Make create! on a has_many :through association return the association object. Not the collection. Closes #8786 *Pratik Naik*
1628
1629 * Move from select * to select tablename.* to avoid clobbering IDs. Closes #8889 *dasil003*
1630
1631 * Don't call unsupported methods on associated objects when using :include, :method with to_xml #7307, *Manfred Stienstra, jwilger*
1632
1633 * Define collection singular ids method for has_many :through associations. #8763 *Pratik Naik*

1636
1637 * Fix polymorphic has_one associations declared in an abstract class. #8638 *Pratik Naik, Dax Huiberts*
1638
1639 * Fixed validates_associated should not stop on the first error. #4276 *mrj, Manfred Stienstra, Josh Peek*

1656
1657 * Quickref for association methods. #7723 *marclove, Mindsweeper*
1658
1659 * Calculations: return nil average instead of 0 when there are no rows to average. #8298 *davidw*
1660
1661 * acts_as_nested_set: direct_children is sorted correctly. #4761 *Josh Peek, rails@33lc0.net*
1662
1663 * Raise an exception if both attr_protected and attr_accessible are declared. #8507 *stellsmi*
1664
1665 * SQLite, MySQL, PostgreSQL, Oracle: quote column names in column migration SQL statements. #8466 *marclove, lorenjohnson*
1666
1667 * Allow nil serialized attributes with a set class constraint. #7293 *sandofsky*
1668
1669 * Oracle: support binary fixtures. #7987 *Michael Schoen*

1685 * Migrations: add_column supports custom column types. #7742 *jsgarvin, Theory*
1686
1687 * 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*
1688
1689 * Ensure that associations with :dependent => :delete_all respect :conditions option. Closes #8034 *Jack Danger Canty, Josh Peek, Rick Olson*
1690
1691 * belongs_to assignment creates a new proxy rather than modifying its target in-place. #8412 *mmangino@elevatedrails.com*

1712
1713 * Provide brief introduction to what optimistic locking is. *fearoffish*
1714
1715 * Add documentation for :encoding option to mysql adapter. *marclove*
1716
1717 * Added short-hand declaration style to migrations (inspiration from Sexy Migrations, http://errtheblog.com/post/2381) [David Heinemeier Hansson]. Example:
1718
1719 create_table "products" do |t|
1720 t.column "shop_id", :integer
1721 t.column "creator_id", :integer
1722 t.column "name", :string, :default => "Untitled"
1723 t.column "value", :string, :default => "Untitled"
1724 t.column "created_at", :datetime
1725 t.column "updated_at", :datetime
1726 end
1727
1728 ...can now be written as:
1729
1730 create_table :products do |t|
1731 t.integer :shop_id, :creator_id
1732 t.string :name, :value, :default => "Untitled"
1733 t.timestamps
1734 end
1735
1736 * 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*
1737
1738 * Improve performance of calling .create on has_many :through associations. *evan*
1739
1740 * Improved cloning performance by relying less on exception raising #8159 *Blaine*
1741
1742 * Added ActiveRecord::Base.inspect to return a column-view like #<Post id:integer, title:string, body:text> *David Heinemeier Hansson*
1743
1744 * Added yielding of Builder instance for ActiveRecord::Base#to_xml calls *David Heinemeier Hansson*
1745
1746 * Small additions and fixes for ActiveRecord documentation. Closes #7342 *Jeremy McAnally*

1749
1750 * SQLite: binary escaping works with $KCODE='u'. #7862 *tsuka*
1751
1752 * Base#to_xml supports serialized attributes. #7502 *jonathan*
1753
1754 * Base.update_all :order and :limit options. Useful for MySQL updates that must be ordered to avoid violating unique constraints. *Jeremy Kemper*
1755
1756 * 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*
1757
1758 * 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*
1759
1760 * 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*
1761
1762 * 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*
1763
1764 * Allow a polymorphic :source for has_many :through associations. Closes #7143 *protocool*

1769
1770 * Consistently quote primary key column names. #7763 *toolmantim*
1771
1772 * Fixtures: fix YAML ordered map support. #2665 *Manuel Holtgrewe, nfbuckley*
1773
1774 * DateTimes assume the default timezone. #7764 *Geoff Buesing*
1775
1776 * Sybase: hide timestamp columns since they're inherently read-only. #7716 *Mike Joyce*
1777
1778 * Oracle: overflow Time to DateTime. #7718 *Michael Schoen*
1779
1780 * PostgreSQL: don't use async_exec and async_query with postgres-pr. #7727, #7762 *flowdelic, toolmantim*
1781
1782 * Fix has_many :through << with custom foreign keys. #6466, #7153 *naffis, Rich Collins*
1783
1784 * Test DateTime native type in migrations, including an edge case with dates
1785 during calendar reform. #7649, #7724 [fedot, Geoff Buesing]
1786 * SQLServer: correctly schema-dump tables with no indexes or descending indexes. #7333, #7703 *Jakob Skjerning, Tom Ward*
1787
1788 * SQLServer: recognize real column type as Ruby float. #7057 *sethladd, Tom Ward*
1789
1790 * Added fixtures :all as a way of loading all fixtures in the fixture directory at once #7214 *Manfred Stienstra*
1791
1792 * Added database connection as a yield parameter to ActiveRecord::Base.transaction so you can manually rollback [David Heinemeier Hansson]. Example:
1793
1794 transaction do |transaction|
1795 david.withdrawal(100)
1796 mary.deposit(100)
1797 transaction.rollback! # rolls back the transaction that was otherwise going to be successful
1798 end
1799
1800 * Made increment_counter/decrement_counter play nicely with optimistic locking, and added a more general update_counters method *Jamis Buck*
1801
1802 * 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*
1803 Task.cache { Task.find(1); Task.find(1) } # => 1 query
1804
1805 * 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*
1806
1807 * Oracle: fix lob and text default handling. #7344 *gfriedrich, Michael Schoen*
1808
1809 * SQLServer: don't choke on strings containing 'null'. #7083 *Jakob Skjerning*

1811 * MySQL: blob and text columns may not have defaults in 5.x. Update fixtures schema for strict mode. #6695 *Dan Kubb*
1812
1813 * 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*
1814
1815 * MySQL: SET SQL_AUTO_IS_NULL=0 so 'where id is null' doesn't select the last inserted id. #6778 *Jonathan Viney, timc*
1816
1817 * Use Date#to_s(:db) for quoted dates. #7411 *Michael Schoen*
1818
1819 * Don't create instance writer methods for class attributes. Closes #7401 *Rick Olson*
1820
1821 * Docs: validations examples. #7343 *zackchandler*
1822
1823 * Add missing tests ensuring callbacks work with class inheritance. Closes #7339 *sandofsky*
1824
1825 * Fixtures use the table name and connection from set_fixture_class. #7330 *Anthony Eden*
1826
1827 * Remove useless code in #attribute_present? since 0 != blank?. Closes #7249 *Josh Susser*
1828
1829 * Fix minor doc typos. Closes #7157 *Josh Susser*
1830
1831 * Fix incorrect usage of #classify when creating the eager loading join statement. Closes #7044 *Josh Susser*

1833 * SQLServer: quote table name in indexes query. #2928 *keithm@infused.org*
1834
1835 * Subclasses of an abstract class work with single-table inheritance. #5704, #7284 *BertG, nick+rails@ag.arizona.edu*
1836
1837 * Make sure sqlite3 driver closes open connections on disconnect *Rob Rasmussen*
1838
1839 * [DOC] clear up some ambiguity with the way has_and_belongs_to_many creates the default join table name. #7072 *Jeremy McAnally*
1840
1841 * change_column accepts :default => nil. Skip column options for primary keys. #6956, #7048 *Dan Manges, Jeremy Kemper*
1842
1843 * 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*
1844
1845 * Oracle: create_table takes a :sequence_name option to override the 'tablename_seq' default. #7000 *Michael Schoen*
1846
1847 * MySQL: retain SSL settings on reconnect. #6976 *randyv2*
1848
1849 * Apply scoping during initialize instead of create. Fixes setting of foreign key when using find_or_initialize_by with scoping. *Cody Fauser*
1850
1851 * SQLServer: handle [quoted] table names. #6635 *rrich*
1852
1853 * acts_as_nested_set works with single-table inheritance. #6030 *Josh Susser*
1854
1855 * PostgreSQL, Oracle: correctly perform eager finds with :limit and :order. #4668, #7021 *eventualbuddha, Michael Schoen*
1856
1857 * Pass a range in :conditions to use the SQL BETWEEN operator. #6974 *Dan Manges*
1858 Student.find(:all, :conditions => { :grade => 9..12 })
1859
1860 * Fix the Oracle adapter for serialized attributes stored in CLOBs. Closes #6825 *mschoen, tdfowler*
1861
1862 * [DOCS] Apply more documentation for ActiveRecord Reflection. Closes #4055 *Robby Russell*
1863
1864 * [DOCS] Document :allow_nil option of #validate_uniqueness_of. Closes #3143 *Caio Chassot*
1865
1866 * Bring the sybase adapter up to scratch for 1.2 release. *jsheets*
1867
1868 * Rollback new_record? and id when an exception is raised in a save callback. #6910 *Ben Curren, outerim*
1869
1870 * Pushing a record on an association collection doesn't unnecessarily load all the associated records. *Obie Fernandez, Jeremy Kemper*
1871
1872 * Oracle: fix connection reset failure. #6846 *leonlleslie*
1873
1874 * Subclass instantiation doesn't try to explicitly require the corresponding subclass. #6840 *leei, Jeremy Kemper*
1875
1876 * 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*
1877
1878 * 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*
1879
1880 * find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 *vitaly, Jeremy Kemper*
1881
1882 * Add AssociationCollection#create! to be consistent with AssociationCollection#create when dealing with a foreign key that is a protected attribute *Cody Fauser*
1883
1884 * 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*
1885
1886 * Change fixture_path to a class inheritable accessor allowing test cases to have their own custom set of fixtures. #6672 *Zach Dennis*
1887
1888 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*
1889
1890 * Simplify query_attribute by typecasting the attribute value and checking whether it's nil, false, zero or blank. #6659 *Jonathan Viney*
1891
1892 * 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*
1893
1894 * Run validations in the order they were declared. #6657 *obrie*
1895
1896 * 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*
1897
1898 * Simplify association proxy implementation by factoring construct_scope out of method_missing. #6643 *martin*
1899
1900 * Oracle: automatically detect the primary key. #6594 *vesaria, Michael Schoen*
1901
1902 * 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*
1903
1904 * Don't inspect unloaded associations. #2905 *lmarlow*
1905
1906 * SQLite: use AUTOINCREMENT primary key in >= 3.1.0. #6588, #6616 *careo, lukfugl*
1907
1908 * Cache inheritance_column. #6592 *Stefan Kaes*
1909
1910 * Firebird: decimal/numeric support. #6408 *macrnic*
1911
1912 * make add_order a tad faster. #6567 *Stefan Kaes*
1913
1914 * Find with :include respects scoped :order. #5850
1915
1916 * Support nil and Array in :conditions => { attr => value } hashes. #6548 *Assaf, Jeremy Kemper*
1917 find(:all, :conditions => { :topic_id => [1, 2, 3], :last_read => nil }
1918
1919 * 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*
1920
1921 * SQLite: fix calculations workaround, remove count(distinct) query rewrite, cleanup test connection scripts. *Jeremy Kemper*
1922
1923 * SQLite: count(distinct) queries supported in >= 3.2.6. #6544 *Bob Silva*
1924
1925 * Dynamically generate reader methods for serialized attributes. #6362 *Stefan Kaes*
1926
1927 * Deprecation: object transactions warning. *Jeremy Kemper*
1928

1930
1931 * 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*
1932
1933 * Make add_column use the options hash with the Sqlite Adapter. Closes #6464 *obrie*
1934
1935 * Document other options available to migration's add_column. #6419 *grg*
1936
1937 * MySQL: all_hashes compatibility with old MysqlRes class. #6429, #6601 *Jeremy Kemper*
1938
1939 * Fix has_many :through to add the appropriate conditions when going through an association using STI. Closes #5783. *Jonathan Viney*
1940
1941 * fix select_limited_ids_list issues in postgresql, retain current behavior in other adapters *Rick Olson*
1942
1943 * Restore eager condition interpolation, document it's differences *Rick Olson*
1944

1946
1947 * Add #delete support to has_many :through associations. Closes #6049 *Martin Landers*
1948
1949 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
1950
1951 * 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*
1952
1953 * 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*
1954
1955 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*
1956
1957 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
1958
1959 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
1960
1961 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
1962
1963 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
1964
1965 * 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*
1966
1967 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
1968
1969 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*
1970
1971 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*
1972

1974
1975 * Add a :namespace option to AR::Base#to_xml *Michael Koziarski*
1976
1977 * Deprecation tests. Remove warnings for dynamic finders and for the foo_count method if it's also an attribute. *Jeremy Kemper*
1978
1979 * Mock Time.now for more accurate Touch mixin tests. #6213 *Dan Peterson*
1980
1981 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
1982
1983 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
1984
1985 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
1986
1987 * 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*
1988
1989 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
1990
1991 * Document validates_presences_of behavior with booleans: you probably want validates_inclusion_of :attr, :in => [true, false]. #2253 *Bob Silva*
1992
1993 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
1994
1995 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
1996
1997 * Deprecation: update docs. #5998 *Jakob Skjerning, Kevin Clark*
1998
1999 * Add some XmlSerialization tests for ActiveRecord *Rick Olson*
2000
2001 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
2002
2003 * Tighten rescue clauses. #5985 *james@grayproductions.net*
2004
2005 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
2006
2007 * 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*
2008
2009 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
2010
2011 * 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*
2012
2013 * SQLServer: fix eager association test. #5901 *Tom Ward*
2014
2015 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
2016
2017 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
2018
2019 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*
2020
2021 * MySQL: update test schema for MySQL 5 strict mode. #5861 *Tom Ward*
2022
2023 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2024
2025 * 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*
2026
2027 * 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*
2028
2029 # Create a tagging to associate the post and tag.
2030 post.tags << Tag.find_by_name('old')
2031 post.tags.create! :name => 'general'
2032
2033 # Would have been:
2034 post.taggings.create!(:tag => Tag.find_by_name('finally')
2035 transaction do
2036 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
2037 end
2038
2039 * Cache nil results for :included has_one associations also. #5787 *Michael Schoen*
2040
2041 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
2042
2043 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
2044 Example: Invoice::Lineitem is given table name invoice_lineitems
2045
2046 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2047 # people_active_last_name_index, people_active_deactivated_at_index
2048 add_index :people, [:active, :last_name]
2049 add_index :people, [:active, :deactivated_at]
2050 remove_index :people, [:active, :last_name]
2051 remove_index :people, [:active, :deactivated_at]
2052
2053 WARNING: backward-incompatibility. Multicolumn indexes created before this
2054 revision were named using the first column name only. Now they're uniquely
2055 named using all indexed columns.
2056
2057 To remove an old multicolumn index, remove_index :table_name, :first_column
2058
2059 * Fix for deep includes on the same association. *richcollins@gmail.com*
2060
2061 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
2062
2063 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
2064
2065 * Document find's :from option. Closes #5762. *andrew@redlinesoftware.com*
2066
2067 * 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*
2068
2069 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
2070
2071 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
2072
2073 * Add documentation for how to disable timestamps on a per model basis. Closes #5684. *matt@mattmargolis.net Marcel Molina Jr.*
2074
2075 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
2076
2077 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
2078

2084
2085 * Fix announcement of very long migration names. #5722 *blake@near-time.com*
2086
2087 * The exists? class method should treat a string argument as an id rather than as conditions. #5698 *jeremy@planetargon.com*
2088
2089 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
2090
2091 * Added support for conditions on Base.exists? #5689 [Josh Peek]. Examples:
2092
2093 assert (Topic.exists?(:author_name => "David"))
2094 assert (Topic.exists?(:author_name => "Mary", :approved => true))
2095 assert (Topic.exists?(["parent_id = ?", 1]))
2096
2097 * Schema dumper quotes date :default values. *Dave Thomas*
2098
2099 * Calculate sum with SQL, not Enumerable on HasManyThrough Associations. *Dan Peterson*
2100
2101 * Factor the attribute#{suffix} methods out of method_missing for easier extension. *Jeremy Kemper*
2102
2103 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
2104
2105 * Allow #count through a has_many association to accept :include. *Dan Peterson*
2106
2107 * create_table rdoc: suggest :id => false for habtm join tables. *Zed Shaw*
2108
2109 * PostgreSQL: return array fields as strings. #4664 *Robby Russell*
2110
2111 * 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*
2112
2113 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2114
2115 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2116
2117 * 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*
2118
2119 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*
2120
2121 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2122
2123 * Update callbacks documentation. #3970 *Robby Russell <robby@planetargon.com>*
2124
2125 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2126
2127 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2128
2129 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2130
2131 * 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*
2132
2133 * 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*
2134
2135 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2136
2137 * Minor tweak to improve performance of ActiveRecord::Base#to_param.
2138
2139 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2140
2141 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2142
2143 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2144
2145 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2146
2147 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2148
2149 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2150
2151 * 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*
2152 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2153 Person.transaction do
2154 # select * from people where id=1 for update
2155 person = Person.find(1, :lock => true)
2156 person.visits += 1
2157 person.save!
2158 end
2159
2160 * 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*
2161
2162 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2163
2164 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2165
2166 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2167
2168 * 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*
2169
2170 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2171
2172 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2173
2174 ...is the same as:
2175 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2176
2177 This makes it easier to pass in the options from a form or otherwise outside.

2323
2324 * Don't create instance writer methods for class attributes. *Rick Olson*

2430
2431 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
2432
2433 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
2434
2435 * Association collections have an _ids reader method to match the existing writer for collection_select convenience (e.g. employee.task_ids).

2436
2437 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*

2462
2463 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
2464
2465 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
2466
2467 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
2468
2469 * 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*
2470
2471 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
2472
2473 * 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*
2474
2475 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*
2476
2477 * Fixtures: correct escaping of \n and \r. #5859 *evgeny.zislis@gmail.com*
2478
2479 * Migrations: gracefully handle missing migration files. #5857 *eli.gordon@gmail.com*
2480

2482
2483 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2484
2485 * 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*
2486
2487 * 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*
2488
2489 # Create a tagging to associate the post and tag.
2490 post.tags << Tag.find_by_name('old')
2491 post.tags.create! :name => 'general'
2492
2493 # Would have been:
2494 post.taggings.create!(:tag => Tag.find_by_name('finally')
2495 transaction do

2503 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
2504 Example: Invoice::Lineitem is given table name invoice_lineitems
2505
2506 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2507 # people_active_last_name_index, people_active_deactivated_at_index
2508 add_index :people, [:active, :last_name]
2509 add_index :people, [:active, :deactivated_at]
2510 remove_index :people, [:active, :last_name]
2511 remove_index :people, [:active, :deactivated_at]
2512
2513 WARNING: backward-incompatibility. Multicolumn indexes created before this
2514 revision were named using the first column name only. Now they're uniquely
2515 named using all indexed columns.
2516
2517 To remove an old multicolumn index, remove_index :table_name, :first_column

2526
2527 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
2528
2529 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
2530
2531 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
2532
2533 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*

2565 * PostgreSQL: return array fields as strings. #4664 *Robby Russell*
2566
2567 * 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*
2568
2569 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2570
2571 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2572
2573 * 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*
2574
2575 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*
2576
2577 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2578
2579 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2580
2581 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2582
2583 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2584
2585 * 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*
2586
2587 * 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*
2588
2589 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2590
2591 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2592
2593 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2594
2595 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2596
2597 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2598
2599 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2600
2601 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2602
2603 * 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*
2604 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2605 Person.transaction do
2606 # select * from people where id=1 for update
2607 person = Person.find(1, :lock => true)
2608 person.visits += 1
2609 person.save!
2610 end
2611
2612 * 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*
2613
2614 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2615
2616 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2617
2618 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2619
2620 * 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*
2621
2622 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2623
2624 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2625
2626 ...is the same as:
2627 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2628
2629 This makes it easier to pass in the options from a form or otherwise outside.
2630
2631

2640 * Fixed that count distinct should use the selected column even when using :include #5251 *anna@wota.jp*
2641
2642 * 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*
2643
2644 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
2645
2646 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
2647
2648 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
2649 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
2650 Foo.find(:first, :conditions => ['bar_id = ?', bar])
2651
2652 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
2653
2654 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
2655
2656 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*

2668
2669 * Added :allow_nil option for aggregations #5091 *Ian White*
2670
2671 * Fix Oracle boolean support and tests. Closes #5139. *Michael Schoen*
2672
2673 * 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*
2674
2675 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2676
2677 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2678
2679 * 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*
