"""Add permissions for proxy model.

This is needed because of the bug https://code.djangoproject.com/ticket/11154
in Django (as of 1.6, it's not fixed).

When a permission is created for a proxy model, it actually creates if for it's
base model app_label (eg: for "article" instead of "about", for the About proxy
model).

Install Postgres 10, and then:

sudo pg_dropcluster 10 main --stop
sudo pg_upgradecluster 9.6 main
sudo pg_dropcluster 9.6 main

"""
This module provides very simple Django middleware that sleeps on every request.

This is useful when you want to simulate slow response times (as might be
encountered, say, on a cell network).

To use, add this middleware, and add a value for SLEEP_TIME to your settings.

Possible future feature: Look for an X-Django-Sleep header on each request,
to let the client specify per-request sleep time.
