Django CreateView object.id in get_succes_url pk(id) is NONE and then after redirecting to another URL it prints out created entry ID
I have a problem that I just can't figure out. After creating a work order I want to redirect to the detail page of that work order. Here is my models.py class Radni_nalozi(models.Model): Klijent = models.ForeignKey(Klijenti, on_delete=models.CASCADE) Pacijent = models.CharField(max_length=100) Rok_isporuke = models.DateField() Cijena = models.FloatField(default=0) Napomene = models.CharField(max_length=400,blank=True) Zaduzenja = models.CharField(max_length=400,blank=True) Status = models.CharField(max_length=50, choices=STATUS_CHOICES, default = "OTVOREN") Aktivan = models.BooleanField(default=True) def __str__(self): return f"{self.id} - {self.Klijent}, {self.Pacijent}" And here is my model form: class RadniModelForm(BSModalModelForm): class Meta: model = Radni_nalozi fields = ["Klijent","Pacijent","Rok_isporuke","Napomene","Zaduzenja"] labels = {"Klijent":"Klijent: ", "Pacijent":"Pacijent: ", "Rok_isporuke":"Rok isporuke: ", "Napomene":"Napomene: ","Zaduzenja":"Zaduženja: "} widgets = {'Rok_isporuke': DatePickerInput(options={ "locale":"en-gb", })} I want to create a new work order and I'm using django BSModalCreateView.

Why isn't django recognizing my token after i'm redirecting from browser?
In my frontend i'm logging into an app's api from the browser, I'm then redirected back to a View in my backend which gets a code from the app's api, sends it back in a post request then receives an access token and stores it in a model associated with the current user. I'm using token auth. View: class APICallback(APIView): authentication_class = [authentication.TokenAuthentication] permission_class = [permissions.IsAuthenticated] def api_callback(request, format=None): code = request.GET.get('code') if not code: return Response({'Error': 'Code not found in request'}, status=status.HTTP_400_BAD_REQUEST) response = post('https://accounts.api.com/api/token', data={ 'code': code, }).json() print(response) user = request.user access_token = response.get('access_token') token = APIToken(user=user, access_token=access_token) token.save() return redirect('frontend') I have other Views that make requests and it has been able to get the token to know who the user is, but when this View is called I get a 401 Unauthorized error. How do I let Django know the token I'm receiving from the other app's api belongs to the current user? also... when I take off permissions and authentication class from the View it returns the user as Anonymous User -

How to use custom authentication class inside ListAPIView
I am using react components and to test my code I wrote a quick custom authentication class and defined in the settings for the rest_framework as follow: DEFAULT_AUTHENTICATION_CLASSES += ['restaurant.rest_api.dev.DevAuthentication'] This works great and uses the user I tell it to class DevAuthentication(authentication.BaseAuthentication): def authenticate(self, request): user = User.objects.get(id=6) return (user,None) However, I am now trying to use ListAPIView from generics and the user that prints out is an anonymous user which means that it is not using my authentication class. I found that classes can be explicitly defined inside the function and so I did class SearchUsersAPIView(generics.ListAPIView): search_fields = ['email', 'first_name', 'last_name', 'phone_number'] filter_backends = (filters.SearchFilter,) queryset = CustomUser.objects.all() authentication_classes = [restaurant.rest_api.dev.DevAuthentication] serializer_class = userSerializer @permission_classes([IsAuthenticated]) def dispatch(self,request, *args, **kwargs): self.request = request print(self.request.user) if request.user.is_anonymous or request.user.is_user_superuser()==False: response = Response({"message":"Action Denied"}, status = status.HTTP_400_BAD_REQUEST) response.accepted_renderer = JSONRenderer() response.accepted_media_type = "application/json" response.renderer_context = {} return response return super().dispatch(request,*args, **kwargs) I must add that if I write a simple function view with the api_view decorator the user authenticated is the one that I have specified. I wonder why this is not working only for this class and uses its defaults which are basic and session authentication. Is there a way … -

How to fix errors for Django's Auth/CustomUser after resetting the migrations and db?
After experimenting with setting up CustomUser and many-to-many relationships, I decided to make some (what turned out to be major) changes to the models. I had read that CustomUser/Auth needs to be set up first, or else it'll be a mess. But since I'm just learning and there was barely any data involved, I just went for it--not to mess up the CustomUser model intentionally, but I changed a model name--and (maybe this is the critical error) I updated the names everywhere it appeared. Now I'd deleted and reset the database, VENV folder, all the migration (along with __pycache__) files, and recreated test data so many times that I thought I could download the GitHub repo and set up a fresh new app easily again. But the app refuses to run and keeps asking for a missing table. Re-creating the app isn't my main concern-I'd like to understand what happened-what is this missing table (see the snippet of the error code)? AND: Why is a perfectly intact repo having the same issue with the missing table?

How to get multiple ajax functions to work correctly
I have a django template with two forms in it. When the first form is submitted, an ajax function is triggered and the second form is displayed on the page. When the second form is submitted, the ajax function linked to that form does not seem to work. For testing purposes, I tried to submit the second form before submitting the first form, and the ajax function works as expected. How do I make multiple ajax functions work correctly one after the other? This is my template <div class="form_container"> <div class="form"> <form action="{% url 'process_url' %}" method="post" id="youtube_link_form"> {% csrf_token %} <div class="input-group mb-3"> <input type="text" class="form-control youtube_link_input" placeholder="Put the youtube link or video id" aria-label="youtube_submit_input" aria-describedby="youtube_submit_button" name="youtube_submit_input"> <button class="btn youtube_submit_button" type="submit" id="youtube_submit_button">Submit</button> </div> </form> </div> </div> <div class="user_target_select"> <div class="target_buttons d-flex justify-content-between"> <form method="get" action="{% url 'user_select_positive' %}" id="positive_user_select_form"> <input type="hidden" id="positive_user_select_input" name="positive_user_select_input"> <button class="target_button btn btn-outline-success" id="user_select_positive" type="submit" data-bs-toggle="modal" data-bs-target="#thank_model">Positive</button> </form> </div> </div> Here, user_target_select div is hidden by default. When the first form is submitted, the div is displayed. This is my js file function youtube_link_form_submit(event) { event.preventDefault(); var data = new FormData($('#youtube_link_form').get(0)); $.ajax({ url: $(this).attr('action'), type: $(this).attr('method'), data: data, cache: false, processData: false, contentType: false, success: … -

Web3.Storage site can be used to upload files, but it's also quick and easy to create and run a simple upload script — making it especially convenient to add large numbers of files. The script contains logic to upload a file to Web3.Storage and get a content identifier (CID) in return which would basically be the address to access files. However, in the documentation, the in-built functions are given using Node.js. How can this be done using Django or any other Python based framework? -

Custom Decorator for Django admin.ModelAdmin to Append Actions
I'm trying to create an "export model to csv in admin panel" function and append it to actions in admin.ModelAdmin. By selecting a few rows in a table in the admin panel, the goal is to export the selected rows to csv. However, my current code in decorators.py::exportable_model didn't achieve my goal.
