Caches the groups a user is in so requests don't have to make calls to the database to check group status.

Support
-------

Currently supporting Django 1.8, 1.11, and 2.0 with Python 2.7/Python 3 where support for versions aligns with
Django's support. See the `tox.ini` file for specific Python and Django version pairings.

Documentation
-------------

The full documentation is at https://django-groups-cache.readthedocs.io.

Quickstart
----------

Install django-groups-cache::

    pip install django-groups-cache

Add it to your `INSTALLED_APPS`:

.. code-block:: python

    INSTALLED_APPS = (
        ...
        'groups_cache.apps.GroupsCacheConfig',
        ...
    )

Add the middleware to your `MIDDLEWARE_CLASSES`:

.. code-block:: python

    MIDDLEWARE_CLASSES = (
        'django.contrib.sessions.middleware.SessionMiddleware',
        'django.contrib.auth.middleware.AuthenticationMiddleware',
        ...
        'groups_cache.middleware.GroupsCacheMiddleware',
    )

Checking in a Django Template if the user is in a group name:

.. code-block:: python

    {% if "admins" in request.groups_cache %}
      <a href="/admin">Admin Panel</a>
    {% endif %}

    # or use templatetag, note that templatetag is slower

    {% load has_group %}

    {% if request.user|has_group:"admins" %}
      <a href="/admin">Admin Panel</a>
    {% endif %}

Turn on caching:

.. code-block:: python

    CACHES = {
        'default': {
            'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
            'LOCATION': '127.0.0.1:11211',
        }
    }

See https://docs.djangoproject.com/en/1.10/topics/cache/#memcached for more details on setting
up memcached.

Note**

Using `django.core.cache.backends.locmem.LocMemCache` is not safe for production unless you are
only running a single process (and odds are you aren't).

See https://docs.djangoproject.com/en/1.10/topics/cache/#local-memory-caching for more details.

Features
--------

* Adds `groups_cache` property to `request` object
* Provides templatetag `has_group`
* Invalidates cache on `User` or `Group` model changes and on m2m `groups` ManyToManyField changes
* Fully tested with high coverage


Running Tests
-------------

::

    source <YOURVIRTUALENV>/bin/activate
    (myenv) $ pip install tox
    (myenv) $ tox
