在ModelForm中设置主键

Question

This is my code to load EditScreen for User Model.

@login_required ()            
def getUser (request, userId):

    if request.method  == "GET":
        my_record = User.objects.get(user_id=userId)
        form = UserUpdateForm (instance=my_record)

        print "Registration page loading..."

        return render(request, "EN/updateuser.html", {'form': form } )

But 'user_id' (PrimaryKey) is not going as part of 'form' when I get request for update User I'm not able to get the object instance to update it. How to set it along with the form so that I should be able to read it. I thought of setting it through Hidden Value but I felt that is not a safe way.

Please suggest.

Answer 1

Why do you want to send it as part of the form? You have it in the URL already (and therefore as the userId argument to the view), there's no need to get it from anywhere else.
