E-mail verification with rails 3

Hello everyone

Has anyone a suggestion about how to implement an email verification
system with rails 3 ?

By this I mean, a user subscribes (sign up) receives an email
with a link and has to follow that link to change the status of the
user, only after that the user can login.

What’s the best REST/rails way to do this ?
Could I create more views then create/read/update/delete ?
or is that bad ?

Devise implements this out of the box. You need to implement the
:confirmable option on you migration and model, and you’ll be all set.
