Graphene GAE

A Google AppEngine integration library for Graphene

Upgrade Notes

If you're upgrading from an older version (pre 2.0 version) please check out the Graphene Upgrade Guide.


To install Graphene-GAE on your AppEngine project, go to your project folder and runthis command in your shell:

pip install graphene-gae -t ./libs

This will install the library and its dependencies to the libs folder under your projects root - so the dependencies get uploaded withyour GAE project when you publish your app.

Make sure the libs folder is in your python path by adding the following to your

import sys

for path in ['libs']:
    if path not in sys.path:
        sys.path[0:0] = [path]


Here's a simple GAE model:

class Article(ndb.Model):
    headline = ndb.StringProperty()
    summary = ndb.TextProperty()
    text = ndb.TextProperty()

    author_key = ndb.KeyProperty(kind='Author')

    created_at = ndb.DateTimeProperty(auto_now_add=True)
    updated_at = ndb.DateTimeProperty(auto_now=True)

To create a GraphQL schema for it you simply have to write the following:

import graphene
from graphene_gae import NdbObjectType

class ArticleType(NdbObjectType):
    class Meta:
        model = Article

class Query(graphene.ObjectType):
    articles = graphene.List(ArticleType)

    def resolve_articles(self):
        return Article.query()

schema = graphene.Schema(query=QueryRoot)

Then you can simply query the schema:
