Request.user gives anonymous user in JWT

Question

In my django rest framework project I used json web tocken based authentication and custom user model I want to access requested user object to pass as foreign key when I try request.user it will return AnonymousaUser

views.py

@permission_classes([IsAuthenticated])
@api_view(["POST"])
def createAppoinment(req):
   data=req.data
   serializer=AppoinmentSerializer(data=req.data)
   if serializer.is_valid():

      serializer.save(owner=req.user)   
      return Response(status=status.HTTP_201_CREATED)
   return Response(status=status.HTTP_400_BAD_REQUEST)

I get the following error

ValueError: Cannot assign "<django.contrib.auth.models.AnonymousUser object at 0x000002894FE58A00>": "Appoinment.owner" must be a "NewUser" instance.

How can I get request.user at views in JWT drf and react project

Answer 1

I think you need to change request instead of req here request argument handled standard HTTP REQUEST like(POST,GET,PUT,PATCH,DELETE)

@permission_classes([IsAuthenticated])
@api_view(["POST"])
def createAppoinment(request):
   serializer=AppoinmentSerializer(data=request.data)
   if serializer.is_valid():

    serializer.save(owner=request.user)   
    return Response(status=status.HTTP_201_CREATED)
   return Response(status=status.HTTP_400_BAD_REQUEST)
