Very nice!

24 + if nodes is not None:
25 + for node in nodes:
26 networks = networks.filter(node=node)
27 return networks.order_by('name')

Ideally, I think this logic (the filtering and the order_by) belongs to the form (same as the usual call to form.save() when the form is a modification/creation form).
