Description (last modified by Aymeric Augustin)

Please,
Could you add an example for formfield_for_foreignkey (
https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.formfield_for_foreignkey) showing how to access parent ID for filtering a foreignkey.

I saw on http://www.stereoplex.com/blog/filtering-dropdown-lists-in-the-django-admin

parent_id = request.META['PATH_INFO'].strip('/').split('/')[-1]

Clearly it's not ideal.

Thanks!

Could you explain a bit more what you're trying to achieve?

To help you, we need something like: "here's my models definition, here's my admin definiton, at this URL ... I would like to..."
