Captcha validation inspired by http://blogs.ericmethot.com/captcha

* Captcha images offline generation using a rake task;
* It's stateless and does not require session data.

== Setup

Install plugin:

  script/plugin install git://github.com/wildchild/yacaptcha_validation.git

Generate captcha images:

  rake yacaptcha:generate

Example script for cron to run rake task:

  #!/bin/sh
  export PATH=$PATH:/home/#####/data/rubygems/bin:/home/#####/data/rubygems/gems/bin
  export RUBYLIB=/home/#####/data/rubygems/local/lib/site_ruby/1.8
  export GEM_HOME=/home/#####/data/rubygems/gems

  cd $HOME/../../containers/rails/[app_name]
  echo "Generating captcha images..."
  rake yacaptcha:generate

== Usage

In model simply add validation check:

  validates_captcha :message => ...

In view:

  <dt>
    <%= yacaptcha_image(comment, :title => 'Captcha image validation') %><br/>
    <label for="comment_captcha_validation">Enter text from image</label>
  </dt>
  <dd>
    <%= f.yacaptcha(:style => 'width: 250px') %>
  </dd>
