Unobtrusive Captcha for your Rails forms. Trap Door works by adding a hidden “honeypot” field to your forms that only a spam bot will fill out. A before filter checks for the presence of this field and banishes bots to a spam trap.
script/plugin install git://github.com/hardbap/trap_door.git
<% form_for(@post) do |form| %> <%= trap_door_field %> # the rest of your form...
class PostController < ApplicationController trap_door :only => :create # the rest of your controller...
By default Trap Door names the hidden_field
:affiliate_id. Obviously this won’t work for everyone so you can change the field name by creating an initializer in
config/initializers and telling Trap Door the name it should use for the honeypot field:
TrapDoor.honeypot_field_name = :go_away
