generate_association_writer

v8.1.1 - Show latest stable - Class: ActiveRecord::NestedAttributes::ClassMethods

generate_association_writer(association_name, type)

private

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.
