Django - Reverse Engineering the Admin site's “Add Foreign Key” button

Question

TL;DR (Short synopsis):

I have recreated the admin \"Add\" button in my own project. However, when I hit \"save\" on the parent form, it is not rec

I Figured it Out

The problem was what I was passing to my closeAddPopup javascript function. Essentially, I was passing garbage values.

Here's what I originally had in my New_Zone view (which didn't work):

    ...
    if form.is_valid():
        f = form.save(commit=False)
        pk_value = f.numOfZones
        form.save()
        obj = Zone_Info.objects.get(numOfZones=pk_value)
        if isPopup == "1":
            return HttpResponse('<script>opener.closeAddPopup(window, "%s", "%s");</script>' % (escape(pk_value), escape(obj)))
    ...

It's a pretty stupid mistake on my part (clearly it's late). I was assigning f to the field numOfZones which I thought was the pk and sending that to the script.

Now, the working view looks like this:

       if form.is_valid():
           obj = form.save()
           pk_value = obj.pk
           if "_popup" in request.REQUEST:
               return HttpResponse('<script>opener.closeAddPopup(window, "%s", "%s");</script>' % (escape(pk_value), escape(obj)))

Anyway... thanks to... well, Stackoverflow. I don't think I would have solved the problem without posting the question and rereading my code on stackoverflow.
