Very simple captcha with Rails 3 support

Humanizer

Humanizer is a very simple CAPTCHA method. It has a localized YAML file with questions and answers which is used to validate that the user is an actual human. Any model that includes ActiveModel::Validations should work. Our aim is to be database and mapper agnostic, so if it doesn't work for you, open an issue. Humanizer only works with Rails 3.

Installation

1. gem install humanizer
2. rails g humanizer

Usage

1. In your model, include Humanizer and add the #require_human_on method, example:

      class User < ActiveRecord::Base
        include Humanizer
        require_human_on :create
      end
   

2. Ask the question in the form, example:

      <%= f.label :humanizer_answer, @model.humanizer_question %>
      <%= f.text_field :humanizer_answer %>
      <%= f.hidden_field :humanizer_question_id %>
   

Configuration

Default translations can be found from config/locales/humanizer.en.yml

You might want to add / change question and answer pairs. This can be easily done by adding / modifying entries in locales file.
