User guide

Installation
~~~~~~~~~~~~

Install with pip:

.. code-block:: console

    $ python -m pip install django-async-redis

Configure as cache backend
~~~~~~~~~~~~~~~~~~~~~~~~~~

To start using django-async-redis, you should change your Django cache settings to
something like:

.. code-block:: python

    CACHES = {
        "default": {
            "BACKEND": "django_async_redis.cache.RedisCache",
            "LOCATION": "redis://127.0.0.1:6379/1",
            "OPTIONS": {
                "CLIENT_CLASS": "django_async_redis.client.DefaultClient",
            }
        }
    }

django-async-redis uses the aioredis native URL notation for connection strings, it
allows better interoperability and has a connection string in more "standard"
way. Some examples:

- ``redis://[:password]@localhost:6379/0``
- ``rediss://[:password]@localhost:6379/0``
- ``unix://[:password]@/path/to/socket.sock?db=0``

Three URL schemes are supported:

- ``redis://``: creates a normal TCP socket connection
- ``rediss://``: creates a SSL wrapped TCP socket connection
- ``unix://`` creates a Unix Domain Socket connection

There are several ways to specify a database number:

- A ``db`` querystring option, e.g. ``redis://localhost?db=0``
- If using the ``redis://`` scheme, the path argument of the URL, e.g.
  ``redis://localhost/0``

In some circumstances the password you should use to connect Redis
is not URL-safe, in this case you can escape it or just use the
convenience option in ``OPTIONS`` dict:

.. code-block:: python

    CACHES = {
        "default": {
            "BACKEND": "django_async_redis.cache.RedisCache",
            "LOCATION": "redis://127.0.0.1:6379/1",
            "OPTIONS": {
                "CLIENT_CLASS": "django_async_redis.client.DefaultClient",
                "PASSWORD": "mysecret"
            }
        }
    }

Take care, that this option does not overwrites the password in the uri, so if
you have set the password in the uri, this settings will be ignored.

Notes
-----

Since the majority of this code was ported from django-redis, there was one
case that had needed a monkeypatch. In ``django_async_redis.util``, we implement
``CacheKey`` which subclasses ``str`` which helps us know if a cache key was
already created. Since aioredis, checks if the cache key is of type str
(and others), I had to monkeypatch that check so that a CacheKey instance could
also be accepted.

Credit

- Hey, I'm Andrew. I'm busy in college, but I wanted to help contribute
  to Django's async ecosystem.
- Lots of code is taken from django-redis, including the tests.
  I just needed to port everything to asyncio and aioredis.
- I used cookiecutter-pypackage to generate this project.
- Thank you to Python Discord server's async topical chat
  for helping me understand when to use coroutines over sync functions
  and @Bast and @hmmmm in general because they're OG.
