Django Facetools provides a set of features to ease development of Facecbook canvas apps in a Django project.

Features:

• Replacement url template tag as well as the reverse function that convert an internal url into it's facebook canvas equivalent (ex: http://my_app.mycompany.com/canvas/my_view to https://apps.facebook.com/my_app/my_view)
• Ability to define facebook test users, their permissions, and their initial friends per app. The management command sync_facebook_test_users lets you recreate your test users in your facebook app with one call.
• FacebookTestCase can be used in place of Django's TestCase. Just specify a test user's name, much like a fixture, and the test client will mock Facebook requests to your canvas app, complete with a valid signed request for the specified test user.
• Integration with Facebook package Fandjango (https://github.com/jgorset/fandjango)
