Class Method Details

.assign_metadata_key(key) ⇒ #call(defn, value)

A helper for definitions that store their value in #metadata.

Examples:

Storing application classes with GraphQL types

# Make a custom definition
GraphQL::ObjectType.accepts_definitions(resolves_to_class_names: GraphQL::Define.assign_metadata_key(:resolves_to_class_names))

# After definition, read the key from metadata
PostType.metadata[:resolves_to_class_names] # => [...]

Parameters:

  • key (Object) —

    the key to assign in metadata

Returns:

  • (#call(defn, value)) —

    an assignment for .accepts_definitions which writes key to #metadata
