Djheroku
Djheroku is a helper script that reads Heroku configuration from environment variables and injects them to Django configuration.
Autopilot for Heroku settings
This is an easier way to control what Django does. Just add a few lines to your settings.py:
from djheroku import autopilot autopilot(vars())
Then you can make runtime changes to your application settings:
heroku addons:add sendgrid heroku config:set ADDONS=sendgrid heroku addons:add memcachier heroku config:set ADDONS=sendgrid,memcachier
Djheroku will change the variables accordingly.
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.
