Bad rewrite of html pages

[BoAnd]

I have only rewrite/create the base, index, error and usermenu page. And create some create functions in views.py to handle the requests.

Some activity, wooho :)

This way of rendering views is a bit old and not really used anymore. A rewritten index function with a modern approach (though still function based) could be something along the lines of:

from django.shortcuts import render

def index(request):
    args = {
        'head_title': 'Stregsystem',
        'products': Listing.objects.all()
    }
    return render(request, 'stregsystem/index.html', args)

You might want to consider not sending the head title with all responses, though. I'll comment below on a prettier way to handle this :)
