CustomUserModel has no user_doctors - django

Question

I have a detail page of clinical operation. And i want to make it accessible for only staff's and doctor's related with this operation with ManyToManyField
For do this i did
class OperationPanelView(LoginRequiredMixin,View):
login_url = reverse_lazy("doctor:login")
def get(self,request,id):
operation = OperationModel.objects.get(id=id)
if request.user.user_doctors not in operation.doctor.all():
if DoctorModel.objects.filter(user = request.user).exists():
return redirect("doctor:panel",request.user.id)
elif request.user.is_staff == True:
return redirect("disease:panel",operation.id)
context = {
"operation":operation,
}
return render(request,"operation_detail.html",context)
this has worked for if request.user.user_doctors is not related with this operation's doctors then it will redirects the user to their own panel.
And also has worked for if request.user.user_doctors is related with operation's doctors then page will open.
But didn't worked for if user is staff and gave this error:
RelatedObjectDoesNotExist at /disease/panel/1
CustomUserModel has no user_doctors.
in line 35: if request.user.user_doctors not in operation.doctor.all():
Then i add this condition:
if request.user.user_doctors:
but this gave the same error too
