* Construct an actual ActiveRecord::Relation object for the association scope, ↵Jon Leighton2011-01-071-11/+3

* Remove undocumented feature from has_one where you could pass false as the ↵Jon Leighton2011-01-031-20/+8
| | | | | | | | | | | | second parameter to build_assoc or create_assoc, and the existing associated object would be untouched (the foreign key would not be nullified, and it would not be deleted). If you want behaviour similar to this you can do the following things: * Use :dependent => :nullify (or don't specify :dependent) if you want to prevent the existing associated object from being deleted * Use has_many if you actually want multiple associated objects * Explicitly set the foreign key if, for some reason, you really need to have multiple objects associated with the same has_one. E.g. previous = obj.assoc obj.create_assoc previous.update_attributes(:obj_id => obj.id)

| | | | | | | | | | state:resolved] This required changing the code to keep the association proxy for a belongs_to around, despite its target being nil. Which in turn required various changes to the way that stale target checking is handled, in order to support various edge cases (loaded target is nil then foreign key added, foreign key is changed and then changed back, etc). A side effect is that the code is nicer and more succinct. Note that I am removing test_no_unexpected_aliasing since that is basically checking that the proxy for a belongs_to *does* change, which is the exact opposite of the intention of this commit. Also adding various tests for various edge cases and related things. Phew, long commit message!

* Providing support for :inverse_of as an option to associations.Murray Steele2009-05-041-1/+10
| | | | | | | | | | | | | | | | | | | | | | You can now add an :inverse_of option to has_one, has_many and belongs_to associations. This is best described with an example: class Man < ActiveRecord::Base has_one :face, :inverse_of => :man end class Face < ActiveRecord::Base belongs_to :man, :inverse_of => :face end m = Man.first f = m.face Without :inverse_of m and f.man would be different instances of the same object (f.man being pulled from the database again). With these new :inverse_of options m and f.man are the same in memory instance. Currently :inverse_of supports has_one and has_many (but not the :through variants) associations. It also supplies inverse support for belongs_to associations where the inverse is a has_one and it's not a polymorphic.
