Hi, i'm using postgres and rails, and i've some fields, like first name,
last name, etc, i've set it with the migration to a maximum of 50 chars,
and i've limited in the view the possibility to insert more than 50
chars... have i also to add a validates_length_of in the model for all
of these fields? Which problems may i have to don't put it?

I've been told that if I don't validate in my model, my application is potentially open to non-browser based attacks, both on the app and on the database.
