* Construct an actual ActiveRecord::Relation object for the association scope, ↵Jon Leighton2011-01-071-8/+0
| | | | rather than a hash which is passed to apply_finder_options. This allows more flexibility in how the scope is created, for example because scope.where(a, b) and scope.where(a).where(b) mean different things.

| | | | | | | | | | | | 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)
* When preloading a belongs_to, the target should still be set (to nil) if ↵Jon Leighton2011-01-031-0/+9
| | | | there is no foreign key present. And the loaded flag should be set on the association proxy. This then allows us to remove the foreign_key_present? check from BelongsToAssociation#find_target. Also added a test for the same thing on polymorphic associations.
* Let AssociationCollection#find use #scoped to do its finding. Note that I am ↵Jon Leighton2011-01-031-7/+0
| | | | removing test_polymorphic_has_many_going_through_join_model_with_disabled_include, since this specifies different behaviour for an association than for a regular scope. It seems reasonable to expect scopes and association proxies to behave in roughly the same way rather than having subtle differences.
* Allow assignment on has_one :through where the owner is a new record [#5137 ↵Jon Leighton2011-01-033-22/+53
| | | | | | | | | | 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!
