Project Description

# PCassandra - Pico Cassandra utilities for Django

… because nano is too much, but femto is not enough :-P

  • store User on Cassadra (custom auth backend) - see KNOWN ISSUES
  • store Session on Cassandra (custom session store) - see KNOWN ISSUES
  • configure cqlengine connection parameters from your settings
  • management commands to create keyspace and sync models (auth, session)
  • management commands to create user and superusers
  • a WSGI middleware to setup cqlengine on development server

Since Django’s auth & session backends are by design heavyly coupled with models, the backends included here are basically and copy & paste of Django, adapted for the API of cqlengine models.

### Developed and tested with

  • Python 3.4
  • Django 1.8.3
  • cassandra-driver 2.6.0
  • Cassandra 2.1.8

## Install

$ pip install pcassandra

## Settings

PCassandra adds 2 new settings variables:

  • CASSANDRA_CONNECTION: see connection.py
  • PCASSANDRA_AUTH_USER_MODEL = 'pcassandra.dj18.auth.models.CassandraUser'

And you’ll need to override some defaults values with:

  • AUTHENTICATION_BACKENDS = `['pcassandra.dj18.auth.backend.ModelBackend']
  • AUTH_USER_MODEL = 'pcassandra.DjangoUserProxy'
  • SESSION_ENGINE = 'pcassandra.dj18.session.backend'
  • WSGI_APPLICATION: see wsgi.py for recommended setup

## TODO

  • Auth: add unittest of user model / auth backend
  • Auth: implement user’s permissions
  • Auth: create management command to change user passwords
  • Auth: update last login - DjangoUserProxy.save()
  • Auth: update password hash - EmulatedAbstractBaseUser.check_password()
  • Session: add unittest of session model / backend
  • Session: implement ‘clear_expired()’
  • Both: document the ugliest parts, and create unittests for them
  • generate docs
  • investigate if there is some way to execute Django’s unittests against this implementations

## KNOWN ISSUES

  • User model DOES NOT implements permissions api. Superusers have all the permissions, and non-superusers have no permissions.
  • Session model and session backend is not tested at all
