Hi,
Now when I think about this, even when I POST the form, I would
somehow have to tell Django to check for uniqueness in the following
way: -
SELECT * from my_table WHERE short_name = [short_name parameter goes
here] AND id != [primary key parameter goes here]
and
SELECT * from my_table WHERE name = [name parameter goes here] AND id !
= [primary key parameter goes here]
