[Catalyst] Form validation in insert() and update()?

Fail Early. Fail Often.

Some will say redundancy sucks. I agree, except for where validation is
concerned. If you're writing data from the web into a model, check the
data at the page level, and at the model level.

If you're writing to a model from a command line utility...check data at
the command line level, and the model level...

The trick is to define those check in a way that can be used in both
places....
