pyramid_heroku 0.7.0

A bunch of helpers for successfully running Pyramid on Heroku.

Introduction

pyramid_heroku is a collection of tweens and helpers to successfully run Pyramid on Heroku

It provides the following:

• ClientAddr tween that sets real user’s IP to request.client_addr

• Host tween that sets request.host to proxied X-Forwarded-Host header (note: potential security risk)

• HerokuappAccess tween that denies access to your app’s <app>.herokuapp.com domain for any non-whitelisted IPs.

• migrate.py script for automatically running alembic migrations on deploy.

Installation

Just do

pip install pyramid_heroku

or

easy_install pyramid_heroku

Compatibility

pyramid_heroku runs with pyramid>=1.7 and python>=3.6. Other versions might also work.

Documentation

Usage example for tweens:

def main(global_config, **settings):$ cat .heroku/release.sh
    config = Configurator(settings=settings)
    config.include('pyramid_heroku.client_addr')
    config.include('pyramid_heroku.herokuapp_access')
    return config.make_wsgi_app()

The pyramid_heroku.herokuapp_access tween depends on pyramid_heroku.client_addr tween and it requires you to list whitelisted IPs in the pyramid_heroku.herokuapp_whitelist setting.

Usage example for automatic alembic migration script:

$ cat .heroku/release.sh
#!/usr/bin/env bash

set -e

echo "Running migrations"
python -m pyramid_heroku.migrate my_app etc/production.ini

echo "DONE!"

For migration script to work, you need to set the MIGRATE_API_SECRET_HEROKU env var in Heroku. This allows the migration script to use the Heroku API.

See tests for more examples.

If you use structlog, add the following configuration setting to your INI file to enable structlog-like logging:

pyramid_heroku.structlog = true
