Heroku support

Heroku Conversion

• django-secure settings (see ce8a8095622c914f9e442ec7da0cbddc7d63bdf0)
  • Check with django-admin.py checksecure and make them pass tests, unless they cause bugs like the above
• Config vars (e-mail etc.)
  • https://devcenter.heroku.com/articles/config-vars
• postinstall/deploy hook
  • https://devcenter.heroku.com/articles/deploy-hooks

.slugignore - which only works for Heroku, apparently.

Maybe I should just adapt it to AWS/Cloud 66 considering the RapGenius imbroglio.

Going to retire this, until Pony Forum moves to something resembling production. I’m not very keen on supporting Heroku with what they’ve done right now.

Signs of postinstall hook: https://github.com/heroku/ruby-rails-sample/blob/b1e1000fedb6ca448dd78702de4fc78dedfee48c/app.json#L7-L9 for one-ish-click deployment.

An example of a more extensive Heroku Deploy script: https://github.com/swanson/stringer/blob/master/app.json.
