Instance Method Summary collapse
-
#associated_object_keys ⇒ Object
The array column in the associated model containing foreign keys to the current model.
-
#can_have_associated_objects?(obj) ⇒ Boolean
many_to_pg_array associations can have associated objects as long as they have a primary key.
-
#default_key ⇒ Object
Assume that the key in the associated table uses a version of the current model’s name suffixed with _ids.
-
#predicate_key ⇒ Object
The hash key to use for the eager loading predicate (left side of IN (1, 2, 3)).
-
#primary_key ⇒ Object
The column in the current table that the keys in the array column in the associated table reference.
-
#remove_before_destroy? ⇒ Boolean
Destroying the associated object automatically removes the association, since the association is stored in the associated object.
