Djheroku 0.4.1

Some helper functionality for binding Heroku configuration to Django

Djheroku is a helper script that reads Heroku configuration from environment variables and injects them to Django configuration.

Configuration helpers

Example:

# settings.py from djheroku import sendgrid vars().update(sendgrid())

This is equivalent of typing in:

# settings.py import os

if ‘SENDGRID_USERNAME’ in os.environ and ‘SENDGRID_PASSWORD’ in os.environ:

EMAIL_HOST = ‘smtp.sendgrid.net’ EMAIL_HOST_USER = os.environ[‘SENDGRID_USERNAME’] EMAIL_HOST_PASSWORD = os.environ[‘SENDGRID_PASSWORD’] EMAIL_PORT = 587 EMAIL_USE_TLS = True

If any of the variables are not present, the configuration will be left as it is. Currently there are two helpers: sendgrid() and mailgun().

Middleware

There are three middleware classes in Djheroku. They are used to redirect permanently from one URL to another.

• NoWwwMiddleware removed www. from URLs of incoming requests. The opposite is built-in functionality of Django. Enable this Middleware and set NO_WWW = True in settings.py to activate.

• PreferredDomainMiddleware redirects all domains directed to the application to a preferred one.

• ForceSSLMiddleware redirects all non-SSL connections to a secure connection.

Each of these middlewares does one thing only and combined they will lead into three separate redirects or even a eternal loop if configured properly wrong.
