-  # may use this to generate methods to compose and decompose such names. The
-  # pattern should use named placeholders as in `shelves/{shelf}/books/{book}`;
-  # those will be taken as hints for the parameter names of the generated
-  # methods. If empty, no name methods are generated.
-  # The entity_name is the name to be used as a basis for generated methods and
