simple_captcha + model

Hi Experts,

l have model called User class User < ActiveRecord::Base   apply_simple_captcha end

in view <%= show_simple_captcha(:object=>"user") %>

in controller @user = User.fiind(params[:id]) if @user.valid_with_captcha?     if @user.update_attributes(params[:use])

First, it seems to me that a model is not where a captcha might want to go. I personally feel it should be in the controller and view, but not in the model.

That said, I have a helper method (well, once I refactor it out into a method) which generates the captcha (for the view) and a simple function which validates it and returns either :success, :failure, or nil. :success means it matched. :failure means it did not. nil means it could not perform the check, either because it could not reach the servers or some internal error to my code. I treat this as :success and move on.
