Class Method Details

.authorized_new(object, context) ⇒ GraphQL::Schema::Object, GraphQL::Execution::Lazy

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.

Make a new instance of this type if the auth check passes, otherwise, raise an error.

Probably only the framework should call this method.

This might return a Execution::Lazy if the user-provided .authorized? hook returns some lazy value (like a Promise).

The reason that the auth check is in this wrapper method instead of new is because of how it might return a Promise. It would be weird if .new returned a promise; It would be a headache to try to maintain Promise-y state inside a GraphQL::Schema::Object instance. So, hopefully this wrapper method will do the job.
