Re: How to implement "helper" fields in my model?

Well, I think the validation part would go in a controller, so you
would want to have the beforesave helper call a function in a
controller, this could also call a component, if needed... I haven't
done this myself but I think this is the correct procedure based on my
understanding of cakephp although I'm fairly new myself to using it.
