| | | | historical and practical reasons, :delete_all is the default deletion strategy employed by association.delete(*records), despite the fact that the default strategy is :nullify for regular has_many. Also, this only works at all if the source reflection is a belongs_to. For other situations, you should directly modify the through association.

* Construct an actual ActiveRecord::Relation object for the association scope, ↵Jon Leighton2011-01-071-13/+8

* Create the association scope directly rather than going through with_scopeJon Leighton2011-01-031-9/+6

| | | | 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.
* Rename AssociationProxy#foreign_key_present to foreign_key_present?Jon Leighton2011-01-031-1/+1

* Allow assignment on has_one :through where the owner is a new record [#5137 ↵Jon Leighton2011-01-031-13/+7
| | | | | | | | | | 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!
* Have a proper AssociationReflection#foreign_type method rather than using ↵Jon Leighton2011-01-031-2/+2

* Rename AssociationReflection#primary_key_name to foreign_key, since the ↵Jon Leighton2010-12-311-5/+5

* Add a HasAssociation module for common code for has_* associationsJon Leighton2010-12-261-0/+169
