Hi

What is the best practice for validating objects - for example, if you want to make sure that a data object always has a "date of birth" entered. I know how to add "required fields" to a form - but what if you just want to validate data objects no matter how they are entered.

I use the validate method, like this: http://pastie.org/2869826 - but this only works for "previously created" objects and not for new objects (at least when adding it through modeladmin).

Am I missing anything?
