Developing your website
=======================

Page models
-------------

The django app ``website`` has been created with default models based on pre-built abstract
CodeRed CMS models. You can use these as-is, override existing fields and function, and add
custom fields to these models. After making a change to any of these models, be sure to run
``python manage.py makemigrations`` and ``python manage.py migrate`` to apply the database changes.

Hooks
-----

Building on the concept of wagtail hooks, there are some additional hooks in CodeRed CMS

is_request_cacheable
^^^^^^^^^^^^^^^^^^^^

The callable passed into this hook should take a ``request`` argument, and return a ``bool``
indicating whether or not the response to this request should be cached (served from the
cache if it is already cached). Not returning, or returning anything other than a bool will
not affect the caching decision. For example::

    from wagtail.core import hooks

    @hooks.register('is_request_cacheable')
    def nocache_in_query(request):
        # if the querystring contains a "nocache" key, return False to forcibly not cache.
        # otherwise, do not return to let the CMS decide how to cache.
        if 'nocache' in request.GET:
            return False
