== MiniCaptcha

Minimalistic captcha plugin for rails projects.

Install and integrate to the existing code:
[0) install RMagick and Digest -- if not yet installed]

1) install mini_captcha:
# script/plugin install git@github.com:srejbi/mini_captcha.git

2) add the following lines to your application controller:

 require 'vendor/plugins/mini_captcha/lib/mini_captcha'
 include MiniCaptcha::ControllerHelpers

3) add a map to the MiniCaptcha controller for the MiniCaptcha image display
map.mini_captcha '/mini_captcha/:action', :controller => 'mini_captcha', :action => 'show_image'

4) add a div like this to any view you want to protect with MiniCaptcha from spam:
  ... (your page & form)...
  <div class="..."><%= show_mini_captcha  %> </div>
  ... (your page) ....

5) update the processing controller similarly to the following block:

 if @form.valid?    your original validation
       if mini_captcha_valid?  extend it with checking the MiniCaptchaChallenge
         do whatever...
         flash[:notice] = 'Your form input was correct.'
         redirect as you wish
       else                     belongs to your new validation of MiniCaptchaChallenge (failure branch)
         flash[:error] = 'Failed MiniCaptcha Challenge.'
         punish the 'bot, piss off the user (just kidding ;))
       end                      end of yout new block for MiniCaptchaChallenge failure
     end

6) enjoy getting less, more real comments :-)
