can't validate simple-captcha rails gem

Question

I am running the simple-captcha gem in Rails to generate a captcha on user registration. Registration is handled by the Devise gem. I followed the instructions listed by the author here:

http://expressica.com/simple_captcha/

and the captcha displays on the form. However, the problem is that there is no check to see if the captcha is valid. I can register on the site and put anything I want in the captcha field (even if it doesn't match the captcha) and I can still continue. The author's installation instructions mention validation happens with the following method:

@user.valid_with_captcha?

However, I don't have a create action in my user controller since that is handled by Devise. How can I validate the captcha using the above method?

Thanks!

I recommend to use recaptcha gem. Check out the wiki about how to use it with Devise.
