getting the IntegrityError Message in Django view

I Have a complex model with 6 constrains and i want to get a message to the user which constrain failed when the post-request fails.

 class testView(APIView):
    @staticmethod
    def post(request):
         serializer = testSerializer(data=request.data)

         if not serializer.is_valid():
             return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

         try:
             testModel.objects.create(
                 # all the data
             )
             return testView.get(request)
         except IntegrityError:
             return Response(status=status.HTTP_403_FORBIDDEN)

The exception is called but I cant find the specific constrain that faild in the IntegrityErrorclass.

Is there any way to return the specific Constrain to the User?

(iam using django 3.0.2 with Postgresql)

Get the actual error message from exception

except IntegrityError as e:
    error_message = e.__cause__

As per PEP 3134, a __cause__ attribute is set with the original (underlying) database exception, allowing access to any additional information provided.
