Please read
UPGRADE-v2.0.md
to learn how to upgrade to Graphene 2.0
.
A Django integration for Graphene.
For installing graphene, just run this command in your shell
pip install "graphene-django>=2.0"
INSTALLED_APPS = (
# ...
'graphene_django',
)
GRAPHENE = {
'SCHEMA': 'app.schema.schema' # Where your Graphene schema lives
}
We need to set up a GraphQL
endpoint in our Django app, so we can
serve the queries.
from django.conf.urls import url
from graphene_django.views import GraphQLView
urlpatterns = [
# ...
url(r'^graphql', GraphQLView.as_view(graphiql=True)),
]
Here is a simple Django model:
from django.db import models
class UserModel(models.Model):
name = models.CharField(max_length=100)
last_name = models.CharField(max_length=100)
To create a GraphQL schema for it you simply have to write the following:
from graphene_django import DjangoObjectType
import graphene
class User(DjangoObjectType):
class Meta:
model = UserModel
class Query(graphene.ObjectType):
users = graphene.List(User)
@graphene.resolve_only_args
def resolve_users(self):
return UserModel.objects.all()
schema = graphene.Schema(query=Query)
Then you can simply query the schema:
query = '''
query {
users {
name,
lastName
}
}
'''
result = schema.execute(query)
