Helper methods for ActiveRecord

Rails
1

Hi all,
I have several models which all have an email field. This email address
should of course be validated and for that I have this nice regex. But
now I have the email validation method copied throughout my different
models. Which is clearly stupid. I figured I needed a helper (module?)
and use this helper I my models. But I can’t seem to find anyway of
helpers for models, only for the controllers and views. Am I missing
something here?
Any help is greatly appreciated.

I’ve put mine in environment.rb as a constant and then just refer to in
in my model validation.

For more complicated cases, there are two ways to do it: inherit your
models from a common class, or put your helper functions into a mixin.

Excellent! I should have thought of that. Thanks a lot.
