Can I create a new PostgreSQL schema and make migrations with Django at runtime?
I am trying to build a multi-tenant application in Django where each tenant will have a PostgreSQL schema and a different subdomain (So shared Database with isolated schema). For every request that comes to the api I have a Django middleware that sets the PostgreSQL schema. Now I want to know what happens if I have my Django App running in production and I want to add a new schema and run the makemigrations command. Is it OK to do that at runtime, or is there a better way to do this? -

DRF, update or create in post request with multiple fields lookup
I have a DRF API with a model of months, I need to provide a way to make one endpoint for creating or updating objects (so either post or patch endpoint). I tried taking example from these two answers: Multiple Lookup fields answer overriding view's create method for update or create The second answer is using the view and not the serializer and that's a behaviour I would rather keep. My code so far: class MultipleFieldLookupMixin: def get_object(self): queryset = self.get_queryset() queryset = self.filter_queryset(queryset) filter = {} for field in self.lookup_fields: if self.kwargs.get(field, None): filter['field'] = self.kwargs['field'] obj = get_object_or_404(queryset, **filter) self.check_object_permissions(self.request, obj) return obj class MonthsViewSet(ModelViewSet, MultipleFieldLookupMixin): authentication_classes = (TokenAuthentication,) def get_queryset(self): query_set = Month.objects.all() return query_set serializer_class = MonthSerializer lookup_fields = ['month', 'year', 'farm'] def create(self, request, *args, **kwargs): kwarg_field: str = self.lookup_url_kwarg or self.lookup_fields self.kwargs[kwarg_field] = request.data[self.lookup_fields] try: return self.update(request, *args, **kwargs) except Month.DoesNotExist: return super().create(request, *args, **kwargs) serializer: class MonthSerializer(serializers.ModelSerializer): class Meta: model = Month fields = '__all__' So now trying to create or update a field raises the following error: self.kwargs[kwarg_field] = request.data[self.lookup_fields] TypeError: unhashable type: 'list' -

Custom Exceptions with Django Rest Framework
I want to create custom exceptions in DRF. As the DRF documentation states that i can do that by creating a user defined class and inheriting from APIException. That works well but the issue is my application require me to send some type of custom codes along with the HTTP status codes. For example, when an error occurred while creating a ProductCatalog it should return something like this along with HTTP status code. {"code": 4026, "message": "Unable to create catalog"} Such thing is required because although my API worked correctly so the http status code will be 200 but there were some business logic that was not fulfilled hence i need to return some sort of custom code and message to let the client application handle it accordingly. Any kind of help will be appreciated. -

Fetch Data from REST API sends two requests and can't authenticate
I'm trying to fetch data in my React app from an Django server with Django Rest Framework, I'm using the built in token authentication. componentDidMount() { let headers = { "content-type": "application/json", "authorization": "Token <token is here>" }; fetch('http://localhost:8000/api/stats/', { headers: headers, }) .then(res => res.json()) .then((data) => { this.setState({ games: data }) }) .catch(console.log) } Inspecting the page in Chrome reveals this This looks like two separate requests but I'm not sure. The requests that has status (failed) has the headers I provided in React with in it. This request seems to have failed completely, it did not even reach the server. The other request that has the status 401 doesn't have the headers I provided. The request did however get a response from the server. Anyone have an idea what's wrong? -

DRF - Unable to serialize an OrderedDict object containing Object Ids
Background I am using djongo to interface with a MongoDB database. My models make use of an auto-generated _id field of type djongo.models.ObjectIdField and my APIViews are presently executing the .get() and .filter() methods on my model querysets to perform database transactions. The Problem When serializing the aforementioned QuerySet results, my serializers successfully do so and in return yield the serialized data that I can then send across in a Response object through my APIViews. However, I have recently transitioned to executing raw NoSQL queries in place of the .get() and .filter() methods mentioned above. The following page on djongo, under section Using Pymongo commands, details how to use pymongo commands to be able to perform these raw queries. I am able to exploit this fact and have successfully refactored part of my codebase to experiment with these commands. Unfortunately, my existing model serializers will serialize all the data these pymongo commands return except for the _id field of each returned model. Most importantly, .filter(...) would return a QuerySet object, which my serializers handle perfectly fine. Now, something along the lines of .mongo_find(...), which is instead executed on an instance of the DjongoManager, would return an OrderedDict object whose _id … -
