it's code from model

class Jwt(models.Model):      user_id = models.ForeignKey(CustomUser, related_name='login_user', on_delete=models.CASCADE)      access = models.TextField()      refresh = models.TextField()      created_at = models.DateTimeField(auto_now_add=True)      updated_at = models.DateTimeField(auto_now=True)

and this is from view

def get_random(length):      return ''.join(random.choices(string.ascii_uppercase + string.digits, k=length))      def get_access_token(payload):      return jwt.encode(          {"exp": datetime.now() + timedelta(minutes=5), **payload},          settings.SECRET_KEY,          algorithm="HS256"      )      def get_refresh_token():      return jwt.encode(          {"exp": datetime.now() + timedelta(days=365), "data": get_random(10)},          settings.SECRET_KEY,          algorithm="HS256"      )      class LoginView(APIView):      serializer_class = LoginSerializer        def post(self, request):          serializer = self.serializer_class(data=request.data)          serializer.is_valid(raise_exception=True)            user = authenticate(              username=serializer.validated_data['email'],              password=serializer.validated_data['password'])            if not user:              return Response({"error": "Invalid email or password"}, status="400")              access = get_access_token({"user_id": user.id})          refresh = get_refresh_token()            Jwt.objects.create(              user_id=user.id, access=access, refresh=refresh          )            return Response({"access": access, "refresh": refresh})      class RegisterView(APIView):      serializer_class = RegisterSerializer        def post(self, request):          serializer = self.serializer_class(data=request.data)          serializer.is_valid(raise_exception=True)            CustomUser.objects._create_user(**serializer.validated_data)            return Response({"success": "User created."})
