How can I disable the static cache in django?

The solutions depend on the web server technologies used. If you are using nginx as a web server for instance, you can kill the cache for some specific files like:

location ~* \.(css|js)$ {
    expires -1;
}

But I do not recommend doing it that way. This will disable caching completely and force the clients to always download the assets even they have not changed. This is not good practice.

For this reason, I recommend the following approach: simply add a GET parameter after the assets you want to force to download:

<link href="style.css?v=1" rel="stylesheet" type="text/css">

That way, you can control whenever you want the frontend should load the assets again (change the parameter value), and you can still profit from caching your static assets.

This approach applies not only to Django but to all websites.

You can monkey patch view responsible for serving static files:

from functools import wraps

import django.views.static


def no_cache_static(f):
    @wraps(f)
    def static(*a, **kw):
        response = f(*a, **kw)
        response.headers["Cache-Control"] = "no-cache"
        return response

    return static


django.views.static.serve = no_cache_static(django.views.static.serve)
