How to handle multiple notifications model in Django?
I'm trying to build website which monitor multiple websites for changes. For example - if keyword [XYZ] occurs on website A then send notification to user. Currently I'm stuck on adding more notification channels without creating mess in my code. I want to create a abstract class with args target, message, methods like send_message and then inherence from it to SMSNotification, PusherNotification, EmailNotification. Where should I put that logic into project? I was thinking about adding it to models.py, but I'm not sure if this won't cause troubles during further development. What's the proper approach for this? -

testing detail actions in viewsets
I wrote a viewset with a set authentication, permissions and serializers, and would like now to unit test it. The problem is that when executing UserViewSet.as_view(actions={'get': 'retrieve'}) from my test, the viewset dispatch method doesn't set self.detail = True. class UserViewSet(viewsets.ModelViewSet): serializer_class = UserSerializer lookup_field = 'pk' authentication_classes = (FirebaseAuthentication,) permission_classes = (IsFirebaseVerified, IsAuthenticatedOrReadOnly) queryset = User.objects.all() def get_serializer_class(self): ''' if a user queries his own details, or signs up, return his private info ''' # BUG: self.detail is undefined if (self.detail and self.request.user.pk == self.kwargs.get('pk'))\ or self.action == 'create': return PrivateUserSerializer return UserSerializer Related test: def generate_fake_user_data(pk, name): return { 'pk': pk, 'email': '{}@example.com'.format(name.lower()), 'password': 'password{}'.format(name), } class UserViewSetTestCase(TestCase): @classmethod def setUpClass(cls): cls.users = MockSet( User(**generate_fake_user_data(1, 'A')), User(**generate_fake_user_data(2, 'B')), model=User, ) cls.factory = APIRequestFactory() UserViewSet.queryset = cls.users @classmethod def tearDownClass(cls): UserViewSet.queryset = User.objects.all def test_authed_user_retrieves_himself(self): request = self.factory.get('/api/users/1/') force_authenticate(request, user=self.users.first()) retrieve_view = UserViewSet.as_view(actions={'get': 'retrieve'}) response = retrieve_view(request, pk=1) # BUG: response.data has been returned by UserSerializer self.assertDictContainsSubset({ 'pk': 1, 'full_name': 'John A', 'email': 'a@example.com', }, response.data) self.assertFalse('password' in response.data) What would be the proper way to call my view from my test with self.detail being set to True ? -

Django Many2Many Annotation
I have two Django tables: A and B. There's a many2many relationship between them, written in table A. The problem I have is that when I serve this as an API and I present the objects as A.objects.all().values(), the values of B don't showup. I want to annotate Django table A with the ids of the many2many relationship, so that I can pull them when I do A.objects.all().values(), to get A.B_ids=['134','141','1414']. -

Django redirects to /accounts/profile
I have written some middleware that restricts access to all URLs except the exempted ones. A user can access all the URLs only if they are logged in, if not logged-in, a user can only access exempted URLs. The problem comes when the user is logged-in and then tries to access one of the exempted URLs, that is when the redirect occurs (i.e. redirected to /accounts/profile). How can I solve this problem? -
Django Rest Framework: How to show serialized value in django template?
I am trying to show the serialized data in the Django template. I am using Django Rest framework. Using Ajax I have just tried to show the serialized data in a textarea in the html template view. In view.py, at first, I tried to make a dictionary from a list. And then send it to the serializer.py to make it JSON data. After doing this I just send that serialized data. And from the template, I am using ajax to get this data and set this value in a textarea which is get by ID identifier. But it does not show the value in the textarea. In the textarea, it just prints "[object Object]". So, how do I show the serialized data in the textarea? Here is my view.py: @csrf_exempt def result(request): text = request.POST['test'] triples = getTriples(text) keys = ['sub','predi','obj'] demo_data = dict(zip(keys,triples[0])) serializer = SentenceListSerializer(data=demo_data) if serializer.is_valid(): serializer.save() return JsonResponse(serializer.data, safe=False) Ajax code: $.ajax({ url: "{%url 'result' %}", method: 'POST', dataType: 'json', async: true, headers: { 'X-CSRFToken': $("input[name='csrfmiddlewaretoken']").val() }, data: {'test': info}, success: function(response_data){ $('#textareashow').val(response_data); } }); -

How Do I See Which User/Group is Running My Django Application?
I am currently developing my Django loggers and I have a question when it comes to writing to a new file that has not been created yet. I know Django is supposed to create the new file if it is not already there (the log file) and then write to it there. My issue is that, whichever user is running the Django application (presumably the one I launched it under, or even www-data?) does not have access to that directory. How I got it to finally do as I needed, is I opened up the directory to be writable by all. This is, in my opinion very unsafe and definitely not wanted. I tried this to make sure my loggers were properly setup and it works as desired when I make this change. I have since closed off those permissions and now I am back to square 1 until I find out a solution. Main Question How do I find out which user is running Django, or at least whatever it is that is trying to create the file, in order to add them to a group that has write access to that directory? -

Different errors coming from different host values for mysql config in docker project

Which host value is correct and what should be done about the respective error? I'm not actually sure if mysql is running, where it should be running, and how to check its status. -

Django Memcached Authentication Tokens // is_authenticated attribute
I was looking into caching (memcached or redis) user tokens so that we can save a round-trip to DB on every request of our django-rest-framework-api. Had a few questions Is this entirely irresponsible? What method would we override/extend to make this possible? I can't seem to find a single source: we use both the rest_framework IsAuthenticated, and the request.user.is_authenticated across our endpoints If it were safe, what length cache would you recommend? Any advice? Where should I start? -
