Collectfast – A Faster Collectstatic
====================================

The fast ``collectstatic`` for Django projects with S3 as storage
backend.

Running Django's ``collectstatic`` command can become really slow as
more and more files are added to a project, especially if heavy
libraries such as jQuery UI are included in the source. This is a custom
management command that compares the md5 sum of files with S3 and
completely ignores ``modified_time``. The results of the hash lookups
are cached locally using your default Django cache. This can make
deploying much faster!

Installation
------------

Install the app using pip:

::

$ pip install Collectfast

Make sure you have this in your settings file and add ``'collectfast'``
to your ``INSTALLED_APPS``:

.. code:: python
STATICFILES_STORAGE = "storages.backends.s3boto.S3BotoStorage"
AWS_PRELOAD_METADATA = True
INSTALLED_APPS = (
#
'collectfast',
)
For Django 1.7+, ``'collectfast'`` should come before
``'django.contrib.staticfiles'``. For Django versions below 1.7, it
should come after ``'django.contrib.staticfiles'``. Please note, that
failure to do so will cause Django to use
``django.contrib.staticfiles``'s ``collectstatic``.

***Note:** ``preload_metadata`` of the storage class will be overwritten
even if ``AWS_PRELOAD_METADATA`` is not set to True see
`#30 <https://github.com/antonagestam/collectfast/issues/30>`__*

Setup Dedicated Cache Backend
-----------------------------

It's recommended to setup a dedicated cache backend for Collectfast.
Every time Collectfast does not find a lookup for a file in the cache it
will trigger a lookup to the storage backend, so it's recommended to
have a fairly high ``TIMEOUT`` setting.

Set up your dedicated cache in settings.py with the
``COLLECTFAST_CACHE`` setting:

.. code:: python
CACHES = {
'default': {
# Your default cache
},
'collectfast': {
# Your dedicated Collectfast cache
}
}
COLLECTFAST_CACHE = 'collectfast'
By default Collectfast will use the ``default`` cache.

***Note:** Collectfast will never clean the cache of obsolete files. To
clean out the entire cache, use ``cache.clear()``. `Read more about
Django's cache
framework. <https://docs.djangoproject.com/en/stable/topics/cache/>`__*

Usage
-----

Collectfast overrides Django's builtin ``collectstatic`` command so just
run ``python manage.py collectstatic`` as normal. You can disable
collectfast by using the ``--ignore-etag`` option.

You can also disable collectfast by setting
``COLLECTFAST_ENABLED = False`` in your settings file. This is useful
when using a local file storage backend for development.
