The Google APIs Client Library for Python has special support for the Django web framework. In particular, there are classes that simplify the OAuth 2.0 protocol steps. This document describes the Django-specific classes available for working with Flow, Credentials, and Storage objects.

Flows

Use the oauth2client.contrib.django_orm.FlowField class as a Django model field so that Flow objects can easily be stored. When your application is simultaneously going through OAuth 2.0 steps for many users, it's normally best to store per-user Flow objects before the first redirection. This way, your redirection handlers can retrieve the Flow object already created for the user. In the following code, a model is defined that allows Flow objects to be stored and keyed by User:

from django.contrib.auth.models import User
from django.db import models
from oauth2client.contrib.django_orm import FlowField
...
class FlowModel(models.Model):
  id = models.ForeignKey(User, primary_key=True)
  flow = FlowField()

Credentials

Use the oauth2client.contrib.django_orm.CredentialsField class as a Django model field so that Credentials objects can easily be stored. Similar to Flow objects, it's normally best to store per-user Credentials objects. In the following code, a model is defined that allows Credentials objects to be stored and keyed by User:

from django.contrib.auth.models import User
from django.db import models
from oauth2client.contrib.django_orm import CredentialsField
...
class CredentialsModel(models.Model):
  id = models.ForeignKey(User, primary_key=True)
  credential = CredentialsField()

Storage

Use the oauth2client.contrib.django_orm.Storage class to store and retrieve Credentials objects using a model defined with a CredentialsField object. You pass the model, field name for the model key, value for the model key, and field name to the CredentialsField constructor. The following shows how to create, read, and write Credentials objects using the example CredentialsModel class above:

from django.contrib.auth.models import User
from oauth2client.contrib.django_orm import Storage
from your_project.your_app.models import CredentialsModel
...
user = # A User object usually obtained from request.
storage = Storage(CredentialsModel, 'id', user, 'credential')
credential = storage.get()
...
storage.put(credential)
