I’ve installed the ruby-recaptcha gem as instructed here:

[http://bitbucket.org/mml/ruby-recaptcha/wiki/Home](http://bitbucket.org/mml/ruby-recaptcha/wiki/Home)

Here are the steps that I’ve comleted:

1. installed the gem
2. added config.gem ‘ruby-recaptcha’ environment.rb:
3. modified action\_controller.rb

class ApplicationController \< ActionController::Base  
include ReCaptcha::AppHelper

1. modified application\_helper.rb like so:

module ApplicationHelper  
include ReCaptcha::ViewHelper

The inclusion of the Recaptcha::ViewHelper works. Meaning this tag:

\<%= get\_captcha(:options =\> {:theme =\> ‘clean’}) %\>

Renders an image.

However, the controllers are another can of worms:

calls like:

if validate\_recap(params, @user.errors) && @user.save

fail with the following message:

NoMethodError (undefined method `validate\_recap’ for  
#ActionView::Base:0x734b578):

Which tells me that the module is not being mixed into application  
controller and not then not inherited.

Does anybody have any ideas? Is ruby-recaptcha a reputable product?
