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

tenderlove authored
106 * Added a `with_lock` method to ActiveRecord objects, which starts
107 a transaction, locks the object (pessimistically) and yields to the block.
108 The method takes one (optional) parameter and passes it to `lock!`.
109

111
112 class Order < ActiveRecord::Base

joshsusser authored
212 * Generated association methods are created within a separate module to allow overriding and
213 composition using `super`. For a class named `MyModel`, the module is named
214 `MyModel::GeneratedFeatureMethods`. It is included into the model class immediately after
215 the `generated_attributes_methods` module defined in ActiveModel, so association methods
216 override attribute methods of the same name. *Josh Susser*

jonleighton authored
238 * Allow the :class_name option for associations to take a symbol (:Client) in addition to
239 a string ('Client').
240
241 This is to avoid confusing newbies, and to be consistent with the fact that other options
242 like :foreign_key already allow a symbol or a string.
243
244 *Jon Leighton*
245
246 * In development mode the db:drop task also drops the test database. For symmetry with
247 the db:create task. *Dmitriy Kiriyenko*
248
249 * Added ActiveRecord::Base.store for declaring simple single-column key/value stores *DHH*
250
251 class User < ActiveRecord::Base
252 store :settings, accessors: [ :color, :homepage ]
253 end

255 u = User.new(color: 'black', homepage: '37signals.com')
256 u.color # Accessor stored attribute
257 u.settings[:country] = 'Denmark' # Any attribute, even if not specified with an accessor

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

265 * Transactional fixtures enlist all active database connections. You can test
266 models on different connections without disabling transactional fixtures.
267
268 *Jeremy Kemper*
269
270 * Add first_or_create, first_or_create!, first_or_initialize methods to Active Record. This is a
271 better approach over the old find_or_create_by dynamic methods because it's clearer which
272 arguments are used to find the record and which are used to create it:

368
369 * CollectionProxy#replace should change the DB records rather than just mutating the array.
370 Fixes #3020.
371
372 *Jon Leighton*
373
374 * LRU cache in mysql and sqlite are now per-process caches.
375
376 * lib/active_record/connection_adapters/mysql_adapter.rb: LRU cache keys are per process id.
377 * lib/active_record/connection_adapters/sqlite_adapter.rb: ditto
378 *Aaron Patterson*
379
380 * Support bulk change_table in mysql2 adapter, as well as the mysql one. *Jon Leighton*
381
382 * If multiple parameters are sent representing a date, and some are blank, the
383 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]
384 * ActiveRecord::Base.establish_connection now takes a string that contains
385 a URI that specifies the connection configuration. For example:
386 ActiveRecord::Base.establish_connection 'postgres://localhost/foo'
387
388 * 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.
389
390 So if you were doing this and expecting the second argument to be nil:
391
392 User.find_by_username_and_group("sikachu")
393
394 You'll now get `ArgumentError: wrong number of arguments (1 for 2).` You'll then have to do this:

410
411 Before: def build_association(*options)

413
414 Users who are redefining this method to extend functionality should ensure that the block is
415 passed through to ActiveRecord::Base#new.

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

760 ## Rails 3.0.5 (February 26, 2011) ##
761
762 * Model.where(:column => 1).where(:column => 2) will always produce an AND
763 query.
764 *Aaron Patterson*
765
766 * Deprecated support for interpolated association conditions in the form of :conditions => 'foo = #{bar}'.
767
768 Instead, you should use a proc, like so:
769
770 Before:
771
772 has_many :things, :conditions => 'foo = #{bar}'
773
774 After:
775
776 has_many :things, :conditions => proc { "foo = #{bar}" }
777
778 Inside the proc, 'self' is the object which is the owner of the association, unless you are
779 eager loading the association, in which case 'self' is the class which the association is within.
780
781 You can have any "normal" conditions inside the proc, so the following will work too:
782
783 has_many :things, :conditions => proc { ["foo = ?", bar] }
784
785 Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call
786 'record' to get the record being inserted or deleted. This is now passed as an argument to
787 the proc.
788
789 *Jon Leighton*
790
791
792 ## Rails 3.0.4 (February 8, 2011) ##
793
794 * Added deprecation warning for has_and_belongs_to_many associations where the join table has
795 additional attributes other than the keys. Access to these attributes is removed in 3.1.
796 Please use has_many :through instead. *Jon Leighton*
797
798
799 ## Rails 3.0.3 (November 16, 2010) ##
800
801 * Support find by class like this: Post.where(:name => Post)
802
803
804 ## Rails 3.0.2 (November 15, 2010) ##
805
806 * Dramatic speed increase (see: http://engineering.attinteractive.com/2010/10/arel-two-point-ohhhhh-yaaaaaa/) *Aaron Patterson*
807
808 * reorder is deprecated in favor of except(:order).order(...) *Santiago Pastorino*
809
810 * except is now AR public API
811
812 Model.order('name').except(:order).order('salary')
813
814 generates:
815
816 SELECT * FROM models ORDER BY salary
817
818 *Santiago Pastorino*
819
820 * The following code:
821
822 Model.limit(10).scoping { Model.count }
823
824 now generates the following SQL:
825
826 SELECT COUNT(*) FROM models LIMIT 10
827
828 This may not return what you want. Instead, you may with to do something

838 * Introduce a fix for CVE-2010-3993
839
840
841 ## Rails 3.0.0 (August 29, 2010) ##
842
843 * Changed update_attribute to not run callbacks and update the record directly in the database *Neeraj Singh*
844
845 * Add scoping and unscoped as the syntax to replace the old with_scope and with_exclusive_scope *José Valim*
846
847 * New rake task, db:migrate:status, displays status of migrations #4947 *Kevin Skoglund*
848
849 * select and order for ActiveRecord now always concatenate nested calls. Use reorder if you want the original order to be overwritten *Santiago Pastorino*
850
851 * PostgreSQL: ensure the database time zone matches Ruby's time zone #4895 *Aaron Patterson*
852
853 * Fixed that ActiveRecord::Base.compute_type would swallow NoMethodError #4751 *Andrew Bloomgarden, Andrew White*
854
855 * Add index length support for MySQL. #1852 *Emili Parreno, Pratik Naik*
856
857 Example:
858
859 add_index(:accounts, :name, :name => 'by_name', :length => 10)
860 => CREATE INDEX by_name ON accounts(name(10))
861
862 add_index(:accounts, [:name, :surname], :name => 'by_name_surname', :length => {:name => 10, :surname => 15})
863 => CREATE INDEX by_name_surname ON accounts(name(10), surname(15))
864
865 * find_or_create_by_attr(value, ...) works when attr is protected. #4457 *Santiago Pastorino, Marc-André Lafortune*
866
867 * New callbacks: after_commit and after_rollback. Do expensive operations like image thumbnailing after_commit instead of after_save. #2991 *Brian Durand*
868
869 * 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*
870
871 * 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*
872
873 * PostgreSQL: drop support for old postgres driver. Use pg 0.9.0 or later. *Jeremy Kemper*
874
875 * Observers can prevent records from saving by returning false, just like before_save and friends. #4087 *Mislav Marohnić*
876
877 * Add Relation extensions. *Pratik Naik*
878
879 users = User.where(:admin => true).extending(User::AdminPowers)
880
881 latest_users = User.order('created_at DESC') do
882 def posts_count
883 Post.count(:user_id => to_a.map(&:id))
884 end
885 end
886
887 * To prefix the table names of all models in a module, define self.table_name_prefix on the module. #4032 *Andrew White*
888
889 * 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*
890
891 * 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*
892
893 * Allow relations to be used as scope.
894
895 class Item
896 scope :red, where(:colour => 'red')
897 end
898
899 Item.red.limit(10) # Ten red items
900
901 * Rename named_scope to scope. *Pratik Naik*
902
903 * Changed ActiveRecord::Base.store_full_sti_class to be true by default reflecting the previously announced Rails 3 default *DHH*
904
905 * Add Relation#except. *Pratik Naik*
906
907 one_red_item = Item.where(:colour => 'red').limit(1)
908 all_items = one_red_item.except(:where, :limit)
909
910 * Add Relation#delete_all. *Pratik Naik*
911
912 Item.where(:colour => 'red').delete_all
913
914 * Add Model.having and Relation#having. *Pratik Naik*
915
916 Developer.group("salary").having("sum(salary) > 10000").select("salary")
917
918 * Add Relation#count. *Pratik Naik*
919
920 legends = People.where("age > 100")
921 legends.count
922 legends.count(:age, :distinct => true)
923 legends.select('id').count
924
925 * Add Model.readonly and association_collection#readonly finder method. *Pratik Naik*
926
927 Post.readonly.to_a # Load all posts in readonly mode
928 @user.items.readonly(false).to_a # Load all the user items in writable mode
929
930 * Add .lock finder method *Pratik Naik*
931
932 User.lock.where(:name => 'lifo').to_a
933
934 old_items = Item.where("age > 100")
935 old_items.lock.each {|i| .. }
936
937 * Add Model.from and association_collection#from finder methods *Pratik Naik*
938
939 user = User.scoped
940 user.select('*').from('users, items')
941
942 * Add relation.destroy_all *Pratik Naik*
943
944 old_items = Item.where("age > 100")
945 old_items.destroy_all
946
947 * Add relation.exists? *Pratik Naik*
948
949 red_items = Item.where(:colours => 'red')
950 red_items.exists?
951 red_items.exists?(1)
952
953 * Add find(ids) to relations. *Pratik Naik*
954
955 old_users = User.order("age DESC")
956 old_users.find(1)
957 old_users.find(1, 2, 3)
958
959 * Add new finder methods to association collection. *Pratik Naik*
960
961 class User < ActiveRecord::Base
962 has_many :items
963 end
964
965 user = User.first
966 user.items.where(:items => {:colour => 'red'})
967 user.items.select('items.id')
968
969 * Add relation.reload to force reloading the records. *Pratik Naik*
970
971 topics = Topic.scoped
972 topics.to_a # force load
973 topics.first # returns a cached record
974 topics.reload
975 topics.first # Fetches a new record from the database
976
977 * Rename Model.conditions and relation.conditions to .where. *Pratik Naik*
978
979 Before :
980 User.conditions(:name => 'lifo')
981 User.select('id').conditions(["age > ?", 21])
982
983 Now :
984 User.where(:name => 'lifo')
985 User.select('id').where(["age > ?", 21])
986
987 * Add Model.select/group/order/limit/joins/conditions/preload/eager_load class methods returning a lazy relation. *Pratik Naik*
988
989 Examples :
990
991 posts = Post.select('id).order('name') # Returns a lazy relation
992 posts.each {|p| puts p.id } # Fires "select id from posts order by name"
993
994 * Model.scoped now returns a relation if invoked without any arguments. *Pratik Naik*
995
996 Example :
997
998 posts = Post.scoped
999 posts.size # Fires "select count(*) from posts" and returns the count
1000 posts.each {|p| puts p.name } # Fires "select * from posts" and loads post objects
1001
1002 * Association inverses for belongs_to, has_one, and has_many. Optimization to reduce database queries. #3533 *Murray Steele*
1003
1004 # post.comments sets each comment's post without needing to :include
1005 class Post < ActiveRecord::Base
1006 has_many :comments, :inverse_of => :post
1007 end

1019 * SQLite: drop support for 'dbfile' option in favor of 'database.' #2363 *Paul Hinze, Jeremy Kemper*
1020
1021 * Added :primary_key option to belongs_to associations. #765 *Szymon Nowak, Philip Hallstrom, Noel Rocha*
1022 # employees.company_name references companies.name
1023 Employee.belongs_to :company, :primary_key => 'name', :foreign_key => 'company_name'
1024
1025 * Implement #many? for NamedScope and AssociationCollection using #size. #1500 *Chris Kampmeier*

1062
1063 class Person < ActiveRecord::Base
1064 default_scope :order => 'last_name, first_name'
1065 end
1066
1067 class Company < ActiveRecord::Base
1068 has_many :people
1069 end
1070
1071 Person.all # => Person.find(:all, :order => 'last_name, first_name')

1118
1119 * Allow conditions on multiple tables to be specified using hash. [Pratik Naik]. Example:
1120
1121 User.all :joins => :items, :conditions => { :age => 10, :items => { :color => 'black' } }
1122 Item.first :conditions => { :items => { :color => 'red' } }

1511 belongs_to :article, :counter_cache => :comments_count
1512 end
1513
1514 class Article < ActiveRecord::Base
1515 attr_readonly :approved_comments_count

1533
1534 * Added ActiveRecord::Base#to_json/from_json *David Heinemeier Hansson, Cheah Chu Yeow*
1535
1536 * Added ActiveRecord::Base#from_xml [David Heinemeier Hansson]. Example:

1539 Person.new.from_xml(xml).name # => "David"
1540
1541 * Define dynamic finders as real methods after first usage. *bscofield*

1553 * Extract Firebird, FrontBase, and OpenBase adapters into gems. #9508, #9509, #9510 *Jeremy Kemper*
1554

1556
1557 * Fixed that altering join tables in migrations would fail w/ sqlite3 #7453 *TimoMihaljov/brandon*

1574
1575 * Fixed that eager loading queries and with_scope should respect the :group option *David Heinemeier Hansson*

1578
1579 For more information see: http://dev.rubyonrails.org/ticket/8049
1580
1581 * Don't clobber includes passed to has_many.count *Jack Danger Canty*
1582
1583 * Make sure has_many uses :include when counting *Jack Danger Canty*
1584
1585 * Change the implementation of ActiveRecord's attribute reader and writer methods *Michael Koziarski*
1586 - 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.
1587 * Perform a deep #dup on query cache results so that modifying activerecord attributes does not modify the cached attributes. *Rick Olson*
1588
1589 \# Ensure that has_many :through associations use a count query instead of loading the target when #size is called. Closes #8800 [Pratik Naik]
1590 * Added :unless clause to validations #8003 [monki]. Example:
1591
1592 def using_open_id?
1593 !identity_url.blank?
1594 end
1595
1596 validates_presence_of :identity_url, :if => using_open_id?
1597 validates_presence_of :username, :unless => using_open_id?
1598 validates_presence_of :password, :unless => using_open_id?
1599
1600 * Fix #count on a has_many :through association so that it recognizes the :uniq option. Closes #8801 *Pratik Naik*
1601
1602 * Fix and properly document/test count(column_name) usage. Closes #8999 *Pratik Naik*
1603
1604 * Remove deprecated count(conditions=nil, joins=nil) usage. Closes #8993 *Pratik Naik*
1605
1606 * Change belongs_to so that the foreign_key assumption is taken from the association name, not the class name. Closes #8992 *Josh Susser*
1607
1608 OLD
1609 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is user_id
1610
1611 NEW
1612 belongs_to :visitor, :class_name => 'User' # => inferred foreign_key is visitor_id
1613
1614 * Remove spurious tests from deprecated_associations_test, most of these aren't deprecated, and are duplicated in associations_test. Closes #8987 *Pratik Naik*
1615
1616 * Make create! on a has_many :through association return the association object. Not the collection. Closes #8786 *Pratik Naik*
1617
1618 * Move from select * to select tablename.* to avoid clobbering IDs. Closes #8889 *dasil003*
1619
1620 * Don't call unsupported methods on associated objects when using :include, :method with to_xml #7307, *Manfred Stienstra, jwilger*
1621
1622 * Define collection singular ids method for has_many :through associations. #8763 *Pratik Naik*

1624 * Array attribute conditions work with proxied association collections. #8318 *Kamal Fariz Mahyuddin, theamazingrando*
1625
1626 * Fix polymorphic has_one associations declared in an abstract class. #8638 *Pratik Naik, Dax Huiberts*
1627
1628 * Fixed validates_associated should not stop on the first error. #4276 *mrj, Manfred Stienstra, Josh Peek*
1629

1639
1640 * Fixtures: people(:technomancy, :josh) returns both fixtures. #7880 *technomancy, Josh Peek*
1641
1642 * Calculations support non-numeric foreign keys. #8154 *Kamal Fariz Mahyuddin*
1643
1644 * with_scope is protected. #8524 *Josh Peek*
1645
1646 * Quickref for association methods. #7723 *marclove, Mindsweeper*
1647
1648 * Calculations: return nil average instead of 0 when there are no rows to average. #8298 *davidw*
1649
1650 * acts_as_nested_set: direct_children is sorted correctly. #4761 *Josh Peek, rails@33lc0.net*
1651
1652 * Raise an exception if both attr_protected and attr_accessible are declared. #8507 *stellsmi*
1653
1654 * SQLite, MySQL, PostgreSQL, Oracle: quote column names in column migration SQL statements. #8466 *marclove, lorenjohnson*
1655
1656 * Allow nil serialized attributes with a set class constraint. #7293 *sandofsky*
1657
1658 * Oracle: support binary fixtures. #7987 *Michael Schoen*
1659
1660 * Fixtures: pull fixture insertion into the database adapters. #7987 *Michael Schoen*
1661
1662 * Announce migration versions as they're performed. *Jeremy Kemper*

1674 * Migrations: add_column supports custom column types. #7742 *jsgarvin, Theory*
1675
1676 * 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*
1677
1678 * Ensure that associations with :dependent => :delete_all respect :conditions option. Closes #8034 *Jack Danger Canty, Josh Peek, Rick Olson*
1679
1680 * belongs_to assignment creates a new proxy rather than modifying its target in-place. #8412 *mmangino@elevatedrails.com*
1681
1682 * Fix column type detection while loading fixtures. Closes #7987 *roderickvd*

1701
1702 * Provide brief introduction to what optimistic locking is. *fearoffish*
1703
1704 * Add documentation for :encoding option to mysql adapter. *marclove*
1705
1706 * Added short-hand declaration style to migrations (inspiration from Sexy Migrations, http://errtheblog.com/post/2381) [David Heinemeier Hansson]. Example:
1707
1708 create_table "products" do |t|
1709 t.column "shop_id", :integer
1710 t.column "creator_id", :integer
1711 t.column "name", :string, :default => "Untitled"
1712 t.column "value", :string, :default => "Untitled"
1713 t.column "created_at", :datetime
1714 t.column "updated_at", :datetime
1715 end
1716
1717 ...can now be written as:
1718
1719 create_table :products do |t|
1720 t.integer :shop_id, :creator_id
1721 t.string :name, :value, :default => "Untitled"
1722 t.timestamps
1723 end
1724
1725 * 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*
1726
1727 * Improve performance of calling .create on has_many :through associations. *evan*
1728
1729 * Improved cloning performance by relying less on exception raising #8159 *Blaine*
1730
1731 * Added ActiveRecord::Base.inspect to return a column-view like #<Post id:integer, title:string, body:text> *David Heinemeier Hansson*
1732
1733 * Added yielding of Builder instance for ActiveRecord::Base#to_xml calls *David Heinemeier Hansson*
1734
1735 * Small additions and fixes for ActiveRecord documentation. Closes #7342 *Jeremy McAnally*
1736
1737 * Add helpful debugging info to the ActiveRecord::StatementInvalid exception in ActiveRecord::ConnectionAdapters::SqliteAdapter#table_structure. Closes #7925. *court3nay*
1738
1739 * SQLite: binary escaping works with $KCODE='u'. #7862 *tsuka*
1740
1741 * Base#to_xml supports serialized attributes. #7502 *jonathan*
1742
1743 * Base.update_all :order and :limit options. Useful for MySQL updates that must be ordered to avoid violating unique constraints. *Jeremy Kemper*
1744
1745 * 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*
1746
1747 * 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*
1748
1749 * 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*
1750
1751 * 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*
1752
1753 * Allow a polymorphic :source for has_many :through associations. Closes #7143 *protocool*
1754
1755 * Consistent public/protected/private visibility for chained methods. #7813 *Dan Manges*
1756
1757 * Oracle: fix quoted primary keys and datetime overflow. #7798 *Michael Schoen*
1758
1759 * Consistently quote primary key column names. #7763 *toolmantim*
1760
1761 * Fixtures: fix YAML ordered map support. #2665 *Manuel Holtgrewe, nfbuckley*
1762
1763 * DateTimes assume the default timezone. #7764 *Geoff Buesing*
1764
1765 * Sybase: hide timestamp columns since they're inherently read-only. #7716 *Mike Joyce*
1766
1767 * Oracle: overflow Time to DateTime. #7718 *Michael Schoen*
1768
1769 * PostgreSQL: don't use async_exec and async_query with postgres-pr. #7727, #7762 *flowdelic, toolmantim*
1770
1771 * Fix has_many :through << with custom foreign keys. #6466, #7153 *naffis, Rich Collins*
1772
1773 * Test DateTime native type in migrations, including an edge case with dates
1774 during calendar reform. #7649, #7724 [fedot, Geoff Buesing]
1775 * SQLServer: correctly schema-dump tables with no indexes or descending indexes. #7333, #7703 *Jakob Skjerning, Tom Ward*
1776
1777 * SQLServer: recognize real column type as Ruby float. #7057 *sethladd, Tom Ward*
1778
1779 * Added fixtures :all as a way of loading all fixtures in the fixture directory at once #7214 *Manfred Stienstra*
1780
1781 * Added database connection as a yield parameter to ActiveRecord::Base.transaction so you can manually rollback [David Heinemeier Hansson]. Example:
1782
1783 transaction do |transaction|
1784 david.withdrawal(100)
1785 mary.deposit(100)
1786 transaction.rollback! # rolls back the transaction that was otherwise going to be successful
1787 end
1788
1789 * Made increment_counter/decrement_counter play nicely with optimistic locking, and added a more general update_counters method *Jamis Buck*
1790
1791 * 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*

1830 * change_column accepts :default => nil. Skip column options for primary keys. #6956, #7048 *Dan Manges, Jeremy Kemper*
1831

1860
1861 * Oracle: fix connection reset failure. #6846 *leonlleslie*
1862
1863 * Subclass instantiation doesn't try to explicitly require the corresponding subclass. #6840 *leei, Jeremy Kemper*
1864
1865 * 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*
1866
1867 * 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*
1868

1870
1871 * Add AssociationCollection#create! to be consistent with AssociationCollection#create when dealing with a foreign key that is a protected attribute *Cody Fauser*
1872
1873 * 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*
1874
1875 * Change fixture_path to a class inheritable accessor allowing test cases to have their own custom set of fixtures. #6672 *Zach Dennis*
1876
1877 * Quote ActiveSupport::Multibyte::Chars. #6653 *Julian Tarkhanov*

1880
1881 * 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*
1882
1883 * Run validations in the order they were declared. #6657 *obrie*
1884
1885 * 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*
1886

1923
1924 * Document other options available to migration's add_column. #6419 *grg*
1925

1937
1938 * Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 *Rick Olson*
1939
1940 * 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*
1941

1944 * Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 *jonathan*
1945
1946 * Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 *Bob Silva*
1947
1948 * The has_many create method works with polymorphic associations. #6361 *Dan Peterson*
1949
1950 * MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 *Stefan Kaes*
1951
1952 * save! shouldn't validate twice. #6324 *maiha, Bob Silva*
1953
1954 * 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*
1955
1956 * Add an attribute reader method for ActiveRecord::Base.observers *Rick Olson*
1957
1958 * Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 *Bob Silva*
1959
1960 * has_one associations with a nil target may be safely marshaled. #6279 *norbauer, Jeremy Kemper*
1961

1963
1964 * Add a :namespace option to AR::Base#to_xml *Michael Koziarski*
1965
1966 * Deprecation tests. Remove warnings for dynamic finders and for the foo_count method if it's also an attribute. *Jeremy Kemper*
1967
1968 * Mock Time.now for more accurate Touch mixin tests. #6213 *Dan Peterson*
1969
1970 * Improve yaml fixtures error reporting. #6205 *Bruce Williams*
1971
1972 * Rename AR::Base#quote so people can use that name in their models. #3628 *Michael Koziarski*
1973
1974 * Add deprecation warning for inferred foreign key. #6029 *Josh Susser*
1975
1976 * 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*
1977
1978 * Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 *Josh Susser*
1979
1980 * Document validates_presences_of behavior with booleans: you probably want validates_inclusion_of :attr, :in => [true, false]. #2253 *Bob Silva*
1981
1982 * Optimistic locking: gracefully handle nil versions, treat as zero. #5908 *Tom Ward*
1983
1984 * to_xml: the :methods option works on arrays of records. #5845 *Josh Starcher*
1985
1986 * Deprecation: update docs. #5998 *Jakob Skjerning, Kevin Clark*
1987
1988 * Add some XmlSerialization tests for ActiveRecord *Rick Olson*
1989
1990 * has_many :through conditions are sanitized by the associating class. #5971 *martin.emde@gmail.com*
1991
1992 * Tighten rescue clauses. #5985 *james@grayproductions.net*
1993
1994 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
1995
1996 * 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*
1997
1998 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
1999
2000 * 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*
2001
2002 * SQLServer: fix eager association test. #5901 *Tom Ward*
2003
2004 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*

2011
2012 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2013
2014 * 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*
2015
2016 * 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*
2017
2018 # Create a tagging to associate the post and tag.
2019 post.tags << Tag.find_by_name('old')
2020 post.tags.create! :name => 'general'
2021
2022 # Would have been:
2023 post.taggings.create!(:tag => Tag.find_by_name('finally')
2024 transaction do
2025 post.taggings.create!(:tag => Tag.create!(:name => 'general'))
2026 end
2027
2028 * Cache nil results for :included has_one associations also. #5787 *Michael Schoen*
2029
2030 * Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. *Tobias Lütke*
2031
2032 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
2033 Example: Invoice::Lineitem is given table name invoice_lineitems
2034
2035 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2036 # people_active_last_name_index, people_active_deactivated_at_index
2037 add_index :people, [:active, :last_name]
2038 add_index :people, [:active, :deactivated_at]
2039 remove_index :people, [:active, :last_name]
2040 remove_index :people, [:active, :deactivated_at]
2041
2042 WARNING: backward-incompatibility. Multicolumn indexes created before this
2043 revision were named using the first column name only. Now they're uniquely
2044 named using all indexed columns.
2045
2046 To remove an old multicolumn index, remove_index :table_name, :first_column
2047
2048 * Fix for deep includes on the same association. *richcollins@gmail.com*
2049
2050 * Tweak fixtures so they don't try to use a non-ActiveRecord class. *Kevin Clark*
2051
2052 * Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. *Rick Olson*
2053
2054 * Document find's :from option. Closes #5762. *andrew@redlinesoftware.com*
2055
2056 * 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*
2057
2058 * Replace Reloadable with Reloadable::Deprecated. *Nicholas Seckar*
2059
2060 * Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. *Michael Schoen*
2061
2062 * Add documentation for how to disable timestamps on a per model basis. Closes #5684. *matt@mattmargolis.net Marcel Molina Jr.*
2063
2064 * Don't save has_one associations unnecessarily. #5735 *Jonathan Viney*
2065
2066 * Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. *Rick Olson*
2067
2068 * Formally deprecate the deprecated finders. *Michael Koziarski*
2069
2070 * Formally deprecate rich associations. *Michael Koziarski*
2071
2072 * Fixed that default timezones for new / initialize should uphold utc setting #5709 *daniluk@yahoo.com*
2073
2074 * Fix announcement of very long migration names. #5722 *blake@near-time.com*
2075
2076 * The exists? class method should treat a string argument as an id rather than as conditions. #5698 *jeremy@planetargon.com*
2077
2078 * Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 *alexkwolfe@gmail.com*
2079
2080 * Added support for conditions on Base.exists? #5689 [Josh Peek]. Examples:
2081
2082 assert (Topic.exists?(:author_name => "David"))
2083 assert (Topic.exists?(:author_name => "Mary", :approved => true))
2084 assert (Topic.exists?(["parent_id = ?", 1]))
2085
2086 * Schema dumper quotes date :default values. *Dave Thomas*
2087
2088 * Calculate sum with SQL, not Enumerable on HasManyThrough Associations. *Dan Peterson*
2089
2090 * Factor the attribute#{suffix} methods out of method_missing for easier extension. *Jeremy Kemper*
2091
2092 * Patch sql injection vulnerability when using integer or float columns. *Jamis Buck*
2093
2094 * Allow #count through a has_many association to accept :include. *Dan Peterson*
2095
2096 * create_table rdoc: suggest :id => false for habtm join tables. *Zed Shaw*
2097
2098 * PostgreSQL: return array fields as strings. #4664 *Robby Russell*
2099
2100 * 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*
2101
2102 * SQLServer: fix db:schema:dump case-sensitivity. #4684 *Will Rogers*
2103
2104 * Oracle: BigDecimal support. #5667 *Michael Schoen*
2105
2106 * 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*
2107
2108 * Firebird migrations support. #5337 *Ken Kunz <kennethkunz@gmail.com>*
2109
2110 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2111
2112 * Update callbacks documentation. #3970 *Robby Russell <robby@planetargon.com>*
2113
2114 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2115
2116 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2117
2118 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2119
2120 * 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*
2121
2122 * 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*
2123
2124 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2125
2126 * Minor tweak to improve performance of ActiveRecord::Base#to_param.
2127
2128 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2129
2130 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2131
2132 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2133
2134 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2135
2136 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2137
2138 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2139
2140 * 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*
2141 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2142 Person.transaction do
2143 # select * from people where id=1 for update
2144 person = Person.find(1, :lock => true)
2145 person.visits += 1
2146 person.save!
2147 end
2148
2149 * 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*
2150
2151 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2152
2153 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2154
2155 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2156
2157 * 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*
2158
2159 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2160
2161 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2162
2163 ...is the same as:
2164 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2165
2166 This makes it easier to pass in the options from a form or otherwise outside.
2167
2168
2169 * Fixed issues with BLOB limits, charsets, and booleans for Firebird #5194, #5191, #5189 *kennethkunz@gmail.com*
2170

2455
2456 * Fix spurious newlines and spaces in AR::Base#to_xml output *Jamis Buck*
2457
2458 * 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*
2459
2460 * Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 *Jonathan Viney*
2461
2462 * 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*
2463
2464 * Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 *Kevin Clark*

2467

2472 * to_xml: correct naming of included associations. #5831 *Josh Starcher*
2473
2474 * 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*
2475
2476 * 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*
2477
2478 # Create a tagging to associate the post and tag.
2479 post.tags << Tag.find_by_name('old')
2480 post.tags.create! :name => 'general'
2481
2482 # Would have been:
2483 post.taggings.create!(:tag => Tag.find_by_name('finally')
2484 transaction do
2485 post.taggings.create!(:tag => Tag.create!(:name => 'general'))

2492 * Nested classes are given table names prefixed by the singular form of the parent's table name. *Jeremy Kemper*
2493 Example: Invoice::Lineitem is given table name invoice_lineitems
2494
2495 * Migrations: uniquely name multicolumn indexes so you don't have to. *Jeremy Kemper*
2496 # people_active_last_name_index, people_active_deactivated_at_index

2566 * PostgreSQL: create/drop as postgres user. #4790 *mail@matthewpainter.co.uk, mlaster@metavillage.com*
2567
2568 * PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 *tietew@tietew.net*
2569
2570 * PostgreSQL: correctly quote microseconds in timestamps. #5641 *rick@rickbradley.com*
2571
2572 * Clearer has_one/belongs_to model names (account has_one :user). #5632 *matt@mattmargolis.net*
2573
2574 * 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*
2575
2576 * 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*
2577
2578 * Added :group to available options for finds done on associations #5516 *mike@michaeldewey.org*
2579
2580 * Observers also watch subclasses created after they are declared. #5535 *daniels@pronto.com.au*
2581
2582 * Removed deprecated timestamps_gmt class methods. *Jeremy Kemper*
2583
2584 * rake build_mysql_database grants permissions to rails@localhost. #5501 *brianegge@yahoo.com*
2585
2586 * PostgreSQL: support microsecond time resolution. #5492 *alex@msgpad.com*
2587
2588 * Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum.
2589
2590 * Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. *Sam Stephenson*
2591
2592 * 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*
2593 # Obtain an exclusive lock on person 1 so we can safely increment visits.
2594 Person.transaction do
2595 # select * from people where id=1 for update
2596 person = Person.find(1, :lock => true)
2597 person.visits += 1
2598 person.save!
2599 end
2600
2601 * 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*
2602
2603 * Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. *Jeremy Kemper*
2604
2605 * Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. *Nicholas Seckar*
2606
2607 * Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de)
2608
2609 * 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*
2610
2611 * Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example:
2612
2613 Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2)
2614
2615 ...is the same as:
2616 Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2)
2617
2618 This makes it easier to pass in the options from a form or otherwise outside.
2619
2620
2621 * Fixed issues with BLOB limits, charsets, and booleans for Firebird #5194, #5191, #5189 *kennethkunz@gmail.com*

2626
2627 * Fixed problems with eager loading and counting on SQL Server #5212 *kajism@yahoo.com*
2628
2629 * Fixed that count distinct should use the selected column even when using :include #5251 *anna@wota.jp*
2630
2631 * 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*
2632
2633 * Allow models to override to_xml. #4989 *Blair Zajac <blair@orcaware.com>*
2634
2635 * PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 *shimbo@is.naist.jp*
2636
2637 * Records and arrays of records are bound as quoted ids. *Jeremy Kemper*
2638 Foo.find(:all, :conditions => ['bar_id IN (?)', bars])
2639 Foo.find(:first, :conditions => ['bar_id = ?', bar])
2640
2641 * Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty *David Heinemeier Hansson*
2642
2643 * Add a list of regexes assert_queries skips in the ActiveRecord test suite. *Rick Olson*
2644
2645 * Fix the has_and_belongs_to_many #create doesn't populate the join for new records. Closes #3692 *Josh Susser*
2646
2647 * Provide Association Extensions access to the instance that the association is being accessed from.
2648 Closes #4433 *Josh Susser*

2653
2654 * Add docs for the :as option in has_one associations. Closes #5144 *cdcarter@gmail.com*
2655

2657
2658 * Added :allow_nil option for aggregations #5091 *Ian White*
2659
2660 * Fix Oracle boolean support and tests. Closes #5139. *Michael Schoen*
2661
2662 * 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*
2663
2664 * Call Inflector#demodulize on the class name when eagerly including an STI model. Closes #5077 *info@loobmedia.com*
2665
2666 * Preserve MySQL boolean column defaults when changing a column in a migration. Closes #5015. *pdcawley@bofh.org.uk*
2667
2668 * 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*
