This wiki document describes the gem and it's inner workings.
This gem hopes to keep the bots/spammers at bay. It introduces a hidden field which is seen by the bots and hidden from the prospects. If the field is filled in, it adds an error to the resource/model (in most cases will be a user
) and halts form submission.
The model component validate_captcha
is just a class method. All this method does is adds a new validation definition to your activerecord model class.
The view component provides a new method called, captcha_in_reverse
. All this method does is create a hidden field in your view bound to the resource where it's used.
