* Use bind values for joined tables in where statementsSean Griffin2014-11-011-0/+1
| | | | | | | | | | | | | | | In practical terms, this allows serialized columns and tz aware columns to be used in wheres that go through joins, where they previously would not behave correctly. Internally, this removes 1/3 of the cases where we rely on Arel to perform type casting for us. There were two non-obvious changes required for this. `update_all` on relation was merging its bind values with arel's in the wrong order. Additionally, through associations were assuming there would be no bind parameters in the preloader (presumably because the where would always be part of a join) [Melanie Gilman & Sean Griffin]

* Ambiguous reflections are on :through relationships are no longer supported.Aaron Patterson2013-06-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For example, you need to change this: class Author < ActiveRecord::Base has_many :posts has_many :taggings, :through => :posts end class Post < ActiveRecord::Base has_one :tagging has_many :taggings end class Tagging < ActiveRecord::Base end To this: class Author < ActiveRecord::Base has_many :posts has_many :taggings, :through => :posts, :source => :tagging end class Post < ActiveRecord::Base has_one :tagging has_many :taggings end class Tagging < ActiveRecord::Base end
* rename `Relation#uniq` to `Relation#distinct`. `#uniq` still works.Yves Senn2013-03-151-4/+4
| | | | | | | | The similarity of `Relation#uniq` to `Array#uniq` is confusing. Since our Relation API is close to SQL terms I renamed `#uniq` to `#distinct`. There is no deprecation. `#uniq` and `#uniq!` are aliases and will continue to work. I also updated the documentation to promote the use of `#distinct`.
* Fix cases where delete_records on a has_many association caused errorsDerek Kraan2013-01-271-0/+1
| | | | | | | | | | | | | because of an ambiguous column name. This happened if the association model had a default scope that referenced a third table, and the third table also referenced the original table (with an identical foreign_key). Mysql requires that ambiguous columns are deambiguated by using the full table.column syntax. Postgresql and Sqlite use a different syntax for updates altogether (and don't tolerate table.name syntax), so the fix requires always including the full table.column and discarding it later for Sqlite and Postgresql.

* Added STI support to init and building associationsJason Rush2012-11-291-0/+1
| | | | | | | | Allows you to do BaseClass.new(:type => "SubClass") as well as parent.children.build(:type => "SubClass") or parent.build_child to initialize an STI subclass. Ensures that the class name is a valid class and that it is in the ancestors of the super class that the association is expecting.
* Use method compilation for association methodsJon Leighton2012-08-101-1/+1
| | | | | | | | | Method compilation provides better performance and I think the code comes out cleaner as well. A knock on effect is that methods that get redefined produce warnings. I think this is a good thing. I had to deal with a bunch of warnings coming from our tests, though.

* Deprecate eager-evaluated scopes.Jon Leighton2012-03-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't use this: scope :red, where(color: 'red') default_scope where(color: 'red') Use this: scope :red, -> { where(color: 'red') } default_scope { where(color: 'red') } The former has numerous issues. It is a common newbie gotcha to do the following: scope :recent, where(published_at: Time.now - 2.weeks) Or a more subtle variant: scope :recent, -> { where(published_at: Time.now - 2.weeks) } scope :recent_red, recent.where(color: 'red') Eager scopes are also very complex to implement within Active Record, and there are still bugs. For example, the following does not do what you expect: scope :remove_conditions, except(:where) where(...).remove_conditions # => still has conditions
