ankh

Ankh is the ancient Egyptian sign of life.

Use Ankh in your Rails (>= 3.0) projects to protect against bots and other spam producers. It asks a simple arithmatic question to verify that the poster is human.

In your activerecord model:

class Post < ActiveRecord::Base
  validates_human :on => :create
end

Ankh is also available for ActiveModel objects:

class Foo
  include ActiveModel::Validations
  extend Ankh::Model
  validates_human :on => :create
end

In your view (Rails 2 syntax shown below):

<%- obj.generate_human_question %>
<%- form_for obj do |f| -%>
  <%= f.label :human_answer, obj.human_question %>
  <%= f.text_field :human_answer %>
  <%= f.hidden_field :salted_human_answer %>
<%- end -%>

TODO

  • Nice form helpers

  • I18n support

Note on Patches/Pull Requests

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don't break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

  • Send me a pull request. Bonus points for topic branches.
