Instance Method Summary collapse
-
#associated_object_keys ⇒ Object
An array containing the primary key for the associated model.
-
#can_have_associated_objects?(obj) ⇒ Boolean
pg_array_to_many associations can only have associated objects if the array field is not nil or empty.
-
#dataset_need_primary_key? ⇒ Boolean
pg_array_to_many associations do not need a primary key.
-
#default_key ⇒ Object
Use a default key name of *_ids, for similarity to other association types that use *_id for single keys.
- #filter_by_associations_conditions_expression(obj) ⇒ Object
-
#handle_silent_modification_failure? ⇒ Boolean
Handle silent failure of add/remove methods if raise_on_save_failure is false and save_after_modify is true.
-
#predicate_key ⇒ Object
A qualified version of the associated primary key.
-
#primary_key ⇒ Object
The primary key of the associated model.
-
#primary_key_method ⇒ Object
The method to call to get value of the primary key of the associated model.
