thecoderscamp.com 2👍 I’ve read the code. Looking at LiveServerTestCase for inspiration makes sense but trying to cook up something by extending or somehow calling LiveServerTestCase is asking for trouble and increased maintenance costs. A robust way to run which looks like what LiveServerTestCase does is to create from unittest.TestCase a test case class with custom setUpClass … Read more

The documentation for this is in celery.contrib.methods, and also mentions some caveats you should be aware of: http://docs.celeryproject.org/en/latest/reference/celery.contrib.methods.html Used this as reference 👤securecurve Poor performance of Django ORM with Oracle Source:stackexchange.com
1👍 ✅ After working with our DBAs, it turned out that for some reason the Django get(upi=’xxxxxxxxxxxx’) queries didn’t use the database index. When the same query was rewritten using filter(upi=’xxxxxxxxxxxx’)[:1].get(), the query was fast. The get query was fast only with integer primary keys (it was string in the original question). FINAL SOLUTION create … Read more
1👍 ✅ The request is constructed by the web server. By using the Django development environment, you are presumably using the Werkzeug web server.

3👍 ✅ Django source code (1.8 branch here, line 254) suggests that you can add your ForeignKey to radio_fields or raw_id_fields, resulting in a different widget. In this case, add the field name “Sound” to PlaylistMemberInline.raw_id_fields, consider adding it to PlaylistMemberInline.radio_fields. 👤Freek Wiekmeijer Include list_route methods in Django REST framework's API root Source:stackexchange.com
2👍 ✅ You could try to inherit from DefaultRouter which is responsible for api root view and redefine get_api_root_view method. class MyRouter(routers.DefaultRouter): def get_api_root_view(self): “”” Return a view to use as the API root. “”” api_root_dict = OrderedDict() list_name = self.routes[0].name for prefix, viewset, basename in self.registry: api_root_dict[prefix] = list_name.format(basename=basename) class APIRoot(views.APIView): _ignore_model_permissions = True … Read more
2👍 Looking at Django design philosophies I think they use/combine a lot of different design patterns trying to fulfill the philosophies. It’s difficult to map to a single concept. Tip is to look at Software Design Pattern and it should be possible to identify many patterns are used in django. Many patterns are of course … Read more
