About django-fancy-cache
------------------------

A Django `cache_page` decorator on steroids.

Unlike the stock `django.views.decorators.cache.change_page` this
decorator makes it possible to set a `key_prefixer` that is a
callable. This callable is passed the request and if it returns `None`
the page is not cached.

Also, you can set another callable called `post_process_response`
(which is passed the response and the request) which can do some
additional changes to the response before it's set in cache.

Lastly, you can set `post_process_response_always=True` so that the
`post_process_response` callable is always called, even when the
response is coming from the cache.


How to use it
-------------

In your Django views:

from fancy_cache import cache_page

@cache_page(60 * 60)
def myview(request):
return render(request, 'page1.html')

def prefixer(request):
if request.method != 'GET':
return None
if request.GET.get('no-cache'):
return None
return 'myprefix'

@cache_page(60 * 60, key_prefixer=prefixer)
def myotherview(request):
return render(request, 'page2.html')

def post_processor(response, request):
response.content += '<!-- this was post processed -->'
return response

@cache_page(60 * 60,
key_prefixer=prefixer,
post_process_response=post_processor)
def yetanotherotherview(request):
return render(request, 'page3.html')


Running the test suite
----------------------

The simplest way is to simply run:

$ pip install -r requirements.txt
$ fab test

Or to run it without `fab` you can simply run:

$ export PYTHONPATH=`pwd`
$ export DJANGO_SETTINGS_MODULE=fancy_cache.tests.settings
$ django-admin.py test
