instance method
generate_association_writer
Ruby on Rails edge
Since v4.0.13 Private — implementation detail, not part of the public APISignature
generate_association_writer(association_name, type)Generates a writer method for this association. Serves as a point for accessing the objects in the association. For example, this method could generate the following:
“‘ def pirate_attributes=(attributes)
assign_nested_attributes_for_one_to_one_association(:pirate, attributes)
end “‘
This redirects the attempts to write objects in an association through the helper methods defined below. Makes it seem like the nested associations are just regular associations.
Parameters
-
association_namereq -
typereq
