When creating a package, how do I manage migrations of a weak dependency?
I have a Django app that I would like to package and offer the community through Pipy. Its only strong dependance is Django. It also integrates nicely with Django CMS and offers additional integration for Django CMS. I plan to offer this additional functionality only to projects with Django CMS installed. (This is what I call a weak dependency - will install and work without it, but work even bitter with it.) Specifically, some models are only defined if the base model CMSPlugin from Django CMS is installed. Is there a good/right way to manage migrations, though? I cannot include migrations of models depending on CMSPlugin in the package since users w/o a Django CMS installations will not be able to run it. If I omit the migrations depending on CMSPlugin users with Django CMS will create them on first installation. I fear, however, that on every update of the package those migrations will be lost on pip install upgrade when the package is overwritten. -

django rest framework how to check if phone already exist?

My serializer class teacherInfoCustomSer(serializers.ModelSerializer): class Meta: model = CustomUser fields = ['first_name', 'last_name', 'phone'] apiView def teacherInfoCustom(request, pk): custom = CustomUser.object.get(id=pk) serializer = teacherInfoCustomSer(instance = custom, data = request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data) and my JS let data1 = JSON.stringify({ "first_name": tch_name.value, "last_name": tch_lastname.value, "phone": tch_phone.value }) const teacherInfoCustom = ('/p/teacherInfoCustom/' + "{{ request.user.id }}") fetch(teacherInfoCustom, { method: 'POST', headers: { 'Content-Type': 'application/json', 'X-CSRFToken': csrftoken }, body: data1, }).then((response) => { console.log(response) }).catch(err => { console.log(err.response.message) }) In model's phone field phone = models.CharField(max_length=15, unique=True, blank=True, null=True) and if a phone number already exist it won't give me status 400 but gives status 200 and it didn't save(i think because I set unique=True in my model). And if I enter phone number that didn't exist it will save. -
ValueError: The view did not return an HttpResponse object
I am writing a Django server. I had to use generic views for my API class. Now, Whenever I test the code using postman, everything works fine. But if I test it using other clients like Talend API tester or my Chrome browser, it returns 500 Error saying API did not return any HttpResponse object. Here's my skeleton codebase @method_decorator(csrf_exempt, name='dispatch') class ClassName(View): @throttle def post(self, request) -> JsonResponse: try: data = (json.loads(request.body)) except JSONDecodeError: # decoding error of Json File. msg = "An error occurred while decoding the input" return message_handler(msg, 500) ...... some other application logic ...... return JsonResponse({ "status": True, "message": "", }, status=200) All of my API is using the same format, they are returning a JsonResponse, so what am I doing wrong? -
How to give priority to a certain field in SearchFilter fields in django rest framework?
I have a simple search api which search the db based on the query parameter provided to the search keyboard. It works fine, but it has some issues. For example, I have a category named Tv and home appliances. It has products like LG speakers and led tv. I have search qeury parameters for both category name and product name. When I search tv, speaksers products are coming in the first page while tv products are coming in the 5th page which I dont want. It is because, category name has Tv and Home. What I want is tv prodcuts to be appear in the first page while speakers to the other pages. For this I have to prioritise the product name field rather than category name. How to do that?? { id:1 category: TV and Home, product: 1500 W Speakers } { id:2 category: Tv and Home, product: Led Tv 32" } I want id:2 to be appeared first then, the id:1, if I search with Tv. class PrdouctSearchAPIView(ListAPIView): permission_classes = [AllowAny] queryset = Product.objects.all() print(queryset) serializer_class = ProductSerializer filter_backends = [SearchFilter,OrderingFilter] search_fields = ['name','brand__name','collection__name','sub_category__name', 'description','variants__color','category__name'] pagination_class = CustomPagination My local endpoint is: http://127.0.0.1:8000/api/productsearch?search=tv My model: class Product(models.Model): merchant … -

Django "No Patterns" / Circular Import Error
I've scoured all of the issues I can find about this error and tried all of the solutions, yet none (save one; more on that later) worked for me. Every time I start up my app, I get the following error: django.core.exceptions.ImproperlyConfigured: The included URLconf 'gamerank.urls' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import. I've checked my files for circular imports, and cannot find any at all. voting/urls.py only imports voting/views.py voting/views.py imports voting/models.py, voting/helpers.py, and voting/forms.py voting/models.py imports from libraries only voting/helpers.py imports from libraries only voting/forms.py imports from voting/models.py (which does not import from voting/forms.py) This answer works for me, but I cannot access any of my application after that (because I just commented out the routes), so it's not really a solution in my case.

Is it possible to map all static files or url routes of a website?
I want to make a few static files available in my server, but I don't want people to access it unless they know the exact URL. This is meant to work like a game, solve a puzzle and move to the next phase by finding out the URL. Surely there are several similar games in the web. What I'm worried is if someone could just avoid the puzzle by "mapping" all the static files in a server. Is that possible? [Assuming the puzzle solution would lead to a static file served] I would like to extend the same question for URL routes, is it possible to discover all the url routes of a website? For example I have mysite.com and mysite.com/hidden/solution.html if there are no links to the second URL, can someone get this information? [Except bruteforcing] I'm hosting this page using AWS lightsail (django and apache). Is there something I can/need to do in the django/apache side to prevent this? -

This is my view.py class PersonListCreateAPIView(generics.ListCreateAPIView): serializer_class = PersonSerializer lookup_field = 'uuid' def perform_create(self, serializer): serializer.save(contact_of=self.request.user.get_team) def get_queryset(self): ''' This view should return a list of all the Person objects for the currently authenticated user team. ''' user = self.request.user return Person.objects.filter(contact_of=user.get_team) class PersonRetrieveUpdateDestroyAPIView(generics.RetrieveAPIView): serializer_class = PersonSerializer lookup_field = 'uuid' def get_queryset(self): user = self.request.user return Person.objects.filter(contact_of=user.get_team) This is my urls.py app_name = 'people' urlpatterns = [ # api/people/<uuid> path( route='<uuid:uuid>/', view=PersonRetrieveUpdateDestroyAPIView.as_view(), name='retrieve_update_destroy', ), # api/people/ path( route='', view=PersonListCreateAPIView.as_view(), name='list_create', ), ] Any help? -
