Sorry, I'm not able to understand what your issue is. What do you mean by 'going to a page template' and 'getting back' an FK? I think you need to explain your use case a bit more. A ModelForm is basically for editing and creating instances of a model. Are you trying to use it for navigation? Maybe an example of your view might help. -- DR. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
