I have a Company class. A Company has many Clients, each of which is
also a Company. The problem I have is that in the auto-generated Admin
site, the Clients show up as a multi-select with the Company in the
select box. This doesn't make sense, because a company can't select
itself as a client.
So, how do I specify in the model that the company should not show up
in its list of clients?
I tried to do it by saying the client id should not equal the parent
company id. But I don't seem to be able to get the syntax right.
Can anyone shed light on this? Thanks.
