.assign_type_membership_object_type(object_type) ⇒ Object
This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.
Update a type membership whose .object_type
is a string or late-bound type
so that the type membership’s .object_type
is the given object_type
.
(This is used for updating the union after the schema as lazily loaded the union member.)
