After cloning the repository, create a virtualenv environment and install the prerequisites:

$ virtualenv _installTop_
$ source _installTop_/bin/activate
$ pip install -r testsite/requirements.txt

To use the testsite, you will need to add the payment processor keys (see Processor Backends) and Django secret key into a credentials file. Example with Stripe:

$ cat ./credentials

SECRET_KEY = "_enough_random_data_"
STRIPE_PUB_KEY = "_your_stripe_public_api_key_"
STRIPE_PRIV_KEY = "_your_stripe_private_api_key_"

It remains to create the database and populate it with test data.

$ python ./ migrate --run-syncdb --noinput
$ python ./ loaddata testsite/fixtures/test_data.json

The test_data.json fixture contains the minimal amount of data to make the testsite usable. If you want to load a bigger set of dummy data, you could run the load_test_transactions command.

$ python ./ load_test_transactions

If all is well then, you are ready to run the server and browse the testsite.

$ python runserver

# Browse http://localhost:8000/
# Login with username: alice and password: yoyo

Implementation Notes

The latest versions of django-restframework (>=3.0) implement paginators disconnected from parameters in views (i.e. no more paginate_by). You will thus need to define PAGE_SIZE in your

$ diff testsite/
+    'PAGE_SIZE': 25,
+        'rest_framework.pagination.PageNumberPagination',

This Django App does not send notification e-mails itself. All major updates that would result in a e-mail sent trigger signals though. It is straightforward to send e-mails on a signal trigger in the main Django project. We provide sample e-mail templates here in the saas/templates/notification/ directory.

Release Notes


  • Experimental vue.js front-end
  • trigger more signals when getting closer to renewal time
  • uses broker as a candidate in fail_direct
