formfield_for_foreignkey: how to know if we are modifyng an entry

Hi,

I'm customizing the django admin and I need to do a particular filter
for a foreign key if I'm modifying a model, I'm using the following
method, it works but it seems to me an hack, is there a better way to
do the same thing?

def formfield_for_foreignkey(self, db_field, request, **kwargs):
if db_field.name == "domain":
mod=False
ID=-1
for val in request.path.split('/'):
try:
ID=int(val)
mod=True
break
except:
pass
if mod:
m_user=MailUser.objects.get(pk=ID)
kwargs["queryset"] = Domain.objects.filter(id=m_user.domain_id)
......
return db_field.formfield(**kwargs)
.............
