django-on-heroku

django-on-heroku (Python Library)

This has been forked from django-heroku <https://github.com/heroku/django-heroku>_ because it was abandoned and then renamed to django-on-heroku because old project has been archived.

Current updates:

• renamed package from django-heroku to django-on-heroku
• changed psycopg2 to psycopg2-binary so it works and is installable
• added installation instructions
• fixed wipe'ing tables in Postgres
• whitenoise.middleware.WhiteNoiseMiddleware is injected after django.middleware.security.SecurityMiddleware

This is a Django library for Heroku applications that ensures a seamless deployment and development experience.

This library provides:

• Settings configuration (Static files / WhiteNoise).
• Logging configuration.
• Test runner (important for Heroku CI <https://www.heroku.com/continuous-integration>_).

Django 2.0 is targeted, but older versions of Django should be compatible. Only Python 3 is supported.

Installation

pip install django-on-heroku

Usage of Django-Heroku

In settings.py, at the very bottom::

# Configure Django App for Heroku.
import django_on_heroku
django_on_heroku.settings(locals())

This will automatically configure DATABASE_URL, ALLOWED_HOSTS, WhiteNoise (for static assets), Logging, and Heroku CI for your application.

Bonus points!

If you set the SECRET_KEY environment variable, it will automatically be used in your Django settings, too!

If you set the CONN_MAX_AGE environment variable, it will automatically be used in your database settings, too!

Enabling Functionality ///////////////////////

settings() accepts keyword arguments that are by default set to False

• geodjango - set it to True if you want to use GeoDjango in our app

Disabling Functionality ///////////////////////

settings() also accepts keyword arguments that can be passed False as a value, which will disable automatic configuration for their specific areas of responsibility:

• databases
• test_runner
• staticfiles
• allowed_hosts
• logging
• secret_key
• db_ssl_required

You can also just use this library to provide a test runner for your Django application, for use on Heroku CI::

import django_on_heroku
TEST_RUNNER = 'django_on_heroku.HerokuDiscoverRunner'
