Graphene: Python DSL for GraphQL

Project description

Graphene is a Python library for creating GraphQL schemas/types easly. It maps the models/fields to internal GraphQL objects without effort. Including automatic Django models conversion.


For instaling graphene, just run this command in your shell

pip install graphene


Example code of a GraphQL schema using Graphene:

Schema definition

class Character(graphene.Interface):
    id = graphene.IDField()
    name = graphene.StringField()
    friends = graphene.ListField('self')

    def resolve_friends(self, args, *_):
        return [Human(f) for f in self.instance.friends]

class Human(Character):
    homePlanet = graphene.StringField()

class Query(graphene.ObjectType):
    human = graphene.Field(Human)

schema = graphene.Schema(query=Query)


Querying graphene.Schema is as simple as:

query = '''
    query HeroNameQuery {
      hero {
result = schema.execute(query)

Relay Schema

Graphene also supports Relay, check the Starwars Relay example!

class Ship(relay.Node):
    '''A ship in the Star Wars saga'''
    name = graphene.StringField(description='The name of the ship.')

    def get_node(cls, id):
        return Ship(getShip(id))

class Query(graphene.ObjectType):
    ships = relay.ConnectionField(Ship, description='The ships used by the faction.')
    node = relay.NodeField()

    def resolve_ships(self):
        return [Ship(s) for s in getShips()]

Django+Relay Schema

If you want to use graphene with your Django Models check the Starwars Django example!

class Ship(DjangoNode):
    class Meta:
        model = YourDjangoModelHere
        # only_fields = ('id', 'name') # Only map this fields from the model
        # excluxe_fields ('field_to_excluxe', ) # Exclude mapping this fields from the model

class Query(graphene.ObjectType):
    node = relay.NodeField()


After cloning this repo, ensure dependencies are installed by running:

python install

After developing, the full test suite can be evaluated by running:

python test # Use --pytest-args="-v -s" for verbose mode
