Installation
|
|
------------
|
|
|
|
For instaling graphene, just run this command in your shell
|
|
|
|
.. code:: bash
|
|
|
|
pip install "graphene-django>=1.0"
|
|
|
|
Settings
|
|
~~~~~~~~
|
|
|
|
.. code:: python
|
|
|
|
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.
|
|
|
|
.. code:: python
|
|
|
|
from django.conf.urls import url
|
|
from graphene_django.views import GraphQLView
|
|
|
|
urlpatterns = [
|
|
# ...
|
|
url(r'^graphql', GraphQLView.as_view(graphiql=True)),
|
|
]
|
|
|
|
Examples
|
|
--------
|
|
|
|
Here is a simple Django model:
|
|
|
|
.. code:: python
|
|
|
|
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:
|
|
|
|
.. code:: python
|
|
|
|
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:
|
|
|
|
.. code:: python
|
|
|
|
query = '''
|
|
query {
|
|
users {
|
|
name,
|
|
lastName
|
|
}
|
|
}
|
|
'''
|
|
result = schema.execute(query)
|
|
|
|
