Hi @Mikiya83

Thanks for the patch. I had to research myself, but in the back of my head there was something why this was not enabled. The reason is that this static file serving is only suitable for development, and not for production. This is the reason why it is not enabled in default instances.

The usual approach is to do a collectstatic and expose that directoy in your webserver (Apache, nginx, etc).
In the default docker images we use gunicorn, which does not provide a way to serve static files, so there it is still an unsolved issue.

Ok, indeed if gunicorn is not the "recommended" web server to use, this pull is not necessary, but it could be cool if the default docker image can use static files (without css files it's not very user-friendly ;) )

Indeed! Also, other parts like the web-client which rely on static files will not work at all. But using the static function in production seems to be discouraged by the Django devs.

Maybe we can add it behind the DEBUG flag like in this article?

if settings.DEBUG:
    urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

Why not, it's a good compromise to use DEBUG flag for that !
