Django IsAuthenticated views always return 403
I have various views and viewsets, when I add the IsAuthenticated permission class I always get the 403 forbidden error Response { "detail": "You do not have permission to perform this action." } In views @api_view(["GET"]) @permission_classes([IsAuthenticated]) def protected_profile(request): In viewsets permission_classes = [IsAuthenticated] When I remove this class my requests work I've even checked if request.user.is_authenticated it returns true. It was working few hours back, I've reverted to previous git commits and now the problem continues to persist, my JWT is right as well. I'm on Django 3.2.3 and channels 3.0.3 if that helps. Any help would be appreciated. Edit: the same deployment works fine on heroku. So, I've dropped the DB locally restarted everything but its still the same. -

django transition between pages with saving data
Tell me how to implement, I just can’t figure it out, I’m still learning. Page1 opens and is created with forms.ModelForm +Meta. It has several inputs (text, selects, date) and 2 more inputs: input_hidden and input_text with the "select" button, as well as the "submit" button (sending to save to the database). By clicking on the "select" button, Page2 opens (like a reference book) with a table and a selection button, the desired row is selected in the table through the radiobutton and by pressing the selection button return to Page1 with data, so that the id of the selected element is recorded in input_hidden in value, and the text of the element string itself was written to input_text. At the same time, if before pressing the button on Page1 data were entered into some other inputs, then when returning from Page2, they retained their values. I can assume that it is possible to do something with saving data through a session, or some other simpler way to organize such a process. -

How can I override __str__ in models.py?
Apologies if this is a silly question, I am pretty new to python and django. I am following along with a django tutorial, and we are creating a fake movie site that lists movies by genre, title, etc. I am currently trying to override the __str__ function in the models.py file, so rather than displaying Genre (1), it displays the actual genre (ex. "Action"). Here's how my models.py looks currently: from tkinter import CASCADE from django.db import models from django.utils import timezone # Create your models here. class Genre(models.Model): name = models.CharField(max_length=255) def __str__ (self): return self.name class Movie(models.Model): title = models.CharField(max_length=255) release_year = models.IntegerField() number_in_stock = models.IntegerField() daily_rate = models.FloatField() genre = models.ForeignKey(Genre, on_delete=models.CASCADE) date_created = models.DateTimeField(default=timezone.now) However, vscode is underlining the def __str__ (self): When I hover over it, it tells me: str does not return str pylint(E0307: invalid -str- returned I tried looking at other solutions, but I could not find one that seemed to match my scenario, so I do apologize if this has been solved elsewhere, and I am too incompetent to understand the problem. Thanks for your patience! -

Django: How to download a file on client after an Ajax request
I have a django app where users can save their contacts. I am not building a flow to allow users to download their contacts locally. To do so, I built a CTA ("download") that if clicked Gets the id of the contact selected Triggers an Ajax request to my views In the view I get the contact id, retrieve the data from my DB and create a VCF card out of it. (A contact card - basically a text file) Now I would like to have such file downloaded on the client's machine but I don't know how to do it. I managed to do it if I redirect to a new url where the view does exactly what my view below does, I want to allow users to download the file without being redirected to a new page. Also, trying to avoid storing the contact ids in the URL. That's why I am trying to use ajax but I think that's creating problems because and Ajax request waits JsonReponse from the view. I tried both a GET or POST but it's not working. This is my view currently: def get(self, request, *args, **kwargs): #Get the ids ids = request.GET.getlist('contact_ids[]') … -

So I am trying to figure out how to display the ForeignKey name in the view I have thought about using map method and get the object from the ID and getting the name from said ID, but that doesn't seem to work. I could be doing it wrong but I am not quite sure. JSON Response [ { "id": 3, "name": "Coke", "description": "Cocaine Drink", "container": 3 }, { "id": 4, "name": "Another One", "description": "Dj Khaled Drink", "container": 3 }, { "id": 5, "name": "Testy", "description": "Westy", "container": 4 } ] View class ListDrinks(APIView): authentication_classes = [] permission_classes = [] def get(self, request, format=None): drinks = Drink.objects.all() serializer = DrinkSerializer(map(DrinksId, drinks), many=True) return Response(serializer.data) def post(self, request, format=None): serializer = DrinkSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) Models class Container(models.Model): name = models.CharField(max_length=200) def __str__(self): return self.name class Drink(models.Model): name = models.CharField(max_length=200) description = models.CharField(max_length=500) container = models.ForeignKey( Container, on_delete=models.CASCADE, null=True) def __str__(self): return self.name
