Re: validation in model

thanks, yes i just discovered that myself and now I realise that the
validation has to be different for create and update.

create: needs to check that the name is unique,
update: is unique except for the edited record.

Is the best way to accomplish this by creating another function for
validation on 'update'?

or change the current validation to validate depending on what the action
is?

thanks
