Re: Making a field readonly according to the user in admin.py

These three references should get you started.

get_queryset[1] is useful for filtering the entire display based on the
request user.

readonly_fields[2] is a simple list of fields which are readonly for
everyone.

get_readonly_fields[3] is an Admin callable which can be overridden by
your own method provided your method has the same (request, obj)
signature. In admin.py you would say get get_readonly_fields =
my_get_readonly_fields

I agree with Jani that you will be better off in the long run building
your own interface ... but ymmv
