For some reason, you need to reload your Django URL config.
Normally, the root URL config will be imported and stored in memory when your server process starts up. Occasionally though, you may want to reload it. This can be the case if your URL configuration changes depending on certain parameters.
You can reload the URL config using the following snippet:
import sys from django.conf import settings def reload_urlconf(urlconf=None): if urlconf is None: urlconf = settings.ROOT_URLCONF if urlconf in sys.modules: reload(sys.modules[urlconf])
This was a problem I needed to solve while testing the checkout process for django-oscar. Oscar uses a setting flag to optionally add decorators to certain URLs, and hence I needed to patch the setting and reload the URLs as part of the set-up for a test.
This was achieved in the following way, where the setting
OSCAR_ALLOW_ANON_CHECKOUT is set to
True and the URL config is reloaded.
import sys from django.conf import settings from django.utils.importlib import import_module ... class EnabledAnonymousCheckoutViewsTests(ClientTestCase, CheckoutMixin): def reload_urlconf(self): if settings.ROOT_URLCONF in sys.modules: reload(sys.modules[settings.ROOT_URLCONF]) return import_module(settings.ROOT_URLCONF) def test_shipping_address_requires_session_email_address(self): with patch_settings(OSCAR_ALLOW_ANON_CHECKOUT=True): self.reload_urlconf() response = self.client.get(reverse('checkout:shipping-address')) self.assertIsRedirect(response)
There’s probably a better way of doing this, but it wasn’t apparent to me when working on this problem today.
