Description
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.METAPATH_INFO.strip('/').split('/')[-1]
Clearly it's not ideal.
Thanks!
