Enum is a special
GraphQL type that represents a set of
symbolic names (members) bound to unique, constant values.
You can create an
Enum using classes:
import graphene class Episode(graphene.Enum): NEWHOPE = 4 EMPIRE = 5 JEDI = 6
But also using instances of Enum:
Episode = graphene.Enum('Episode', [('NEWHOPE', 4), ('EMPIRE', 5), ('JEDI', 6)])
It’s possible to add a description to a enum value, for that the the enum value
needs to have the
description property on it.
class Episode(graphene.Enum): NEWHOPE = 4 EMPIRE = 5 JEDI = 6 @property def description(self): if self == Episode.NEWHOPE: return 'New Hope Episode' return 'Other episode'
Usage with Python Enums¶
In case the Enums are already defined it’s possible to reuse them using
