That said, maybe I'm not getting your workflow correctly, but to me it
seems that if request.user is not owner, some fields should be readonly.
And this is what ModelAdmin.get_readonly_fields() is for.
Working on this as we speak!
If this doesn't work for you, can you explain why?
I think it will work!
More later.
It works beautifully!
# in utils.py
def is_public_domain(self, request, obj=None):
"""Return readonly fields. That is the 'modified' fields or all
fields depending on whether the substance is (a) yours or (b) not
yours but the substance is in the public domain. self is the inline
model and obj is the "master" model.
"""
if obj is not None:
if obj.company == get_user_company(request.user):
return self.ro_fields
else:
return self.model._meta.get_all_field_names()

from utils import is_public_domain

""" Limit the substances visible to just those owned by the
company of which the user is a member or those in the public

Thank you very much Melvyn.
