URL Based Database Routing

Question

I set up URL-based database routing inspired by this to use the same application for different projects / databases. Projects do not need to share any data, access control is managed by each project on its own, and I need an admin site for each project. As in the original post, I use a database router and middleware that determines which database will be used from the query path, for example. /test/process/1will be redirected to the database testand /default/process/2to the database default.

import threading
from django.conf import settings

request_cfg = threading.local()

class RouterMiddleware(object):
    def process_view(self, request, view_func, view_args, view_kwargs):
        path = request.path.lstrip('/').split('/')
        if path[0] in settings.DATABASES:
            request_cfg.db = path[0]

    def process_response(self, request, response):
        if hasattr(request_cfg, 'db'):
            del request_cfg.db
        return response

class DatabaseRouter(object):
    def _default_db(self):
        if hasattr(request_cfg, 'db') and request_cfg.db in settings.DATABASES:
            return request_cfg.db
        else:
            return 'default'

    def db_for_read(self, model, **hints):
        return self._default_db()

    def db_for_write(self, model, **hints):
        return self._default_db()
