You either need to serve the CSS file in a way that isn't being handled
by django, or create a django application to serve CSS. Note that the
same applies to image files, or any other media - the chances are they
are static and should thus be served statically, but they could be
generated (or merely output by) a django application.
On my server, which runs Apache, static media is served by using the
following configuration directive:
<Location /static/>
SetHandler None
</Location>
This means that anything in /static is served directly by apache and
doesn't touch Django.
However, as my site is fairly fluid and different applications require
different combinations of CSS (and I love the ability to edit CSS online
as well as the actual pages of my site) I created a relatively simple
single-model application, the details of which are below. Simply, it
searches through the database for files to serve from the /css/
'directory' on the server, so my base template includes the CSS using
the following line:
<link rel="stylesheet" type="text/css" href="/css/default/" />
The important details of the CSS application are below. Note the
somewhat hacky way the regex objects are compiled when the models module
is imported and the models are generated. This is necessary because code
in lambda functions isn't evaluated until the function is called and it
is run, meaning that re objects are no longer in the code's scope. I'm
still not happy with this, as it means that the useragents I can check
for and the regexes that I use are statically emplaced into the code,
but it will do until I find a better solution.
