Re: Admin module - modify SQL Query used for Edit and Save Models

So Tom: i can't use those methods Shawn pointed out?  What I was hoping I can do is override the code that builds the SQL query.

Further looking I think thats correct; as I did get a module working I found and played with which uses those methods and they don't seem to manipulate the query that is built by django, just the value passed. 

What isn't obvious in the Doc's Shawn is what is passed into and what is expected to be returned. The docs are not clear at all about that at all.

This deals with decrypting in python an encrypted value retrieved from
the database (and vice-versa). The OP wants to decrypt the value in
the database, which afaict is not possible easily.
