Module to store the nested_attributes setter methods, so they can call be overridden and call super to get the default behavior
Allow nested attributes to be set for the given associations. Options:
:destroy - Allow destruction of nested records.
:fields - If provided, should be an Array. Restricts the fields allowed to be modified through the association_attributes= method to the specific fields given.
:limit - For *_to_many associations, a limit on the number of records that will be processed, to prevent denial of service attacks.
:remove - Allow disassociation of nested records (can remove the associated object from the parent object, but not destroy the associated object).
:strict - Set to false to not raise an error message if a primary key is provided in a record, but it doesn't match an existing associated object.
If a block is provided, it is passed each nested attribute hash. If the hash should be ignored, the block should return anything except false or nil.
