Spam detection plugin for Rails & ActiveRecord. Uses all the standard Rails conventions and my Despamilator gem. This gem only supports Rails 3. See despamilator_rails2 for Rails 2 support.

To fix the iconv error when developing with Ruby 1.9.2 and RVM, see: blog.footle.org/2010/07/29/installing-ruby-1-9-2-via-rvm-on-os-x/ .

Does not support Rails 2. See despamilator_rails2 for support.
Somewhere (such as your environment.rb…)
require 'despamilator_rails'
In your model (basic example):
class YourModel < ActiveRecord::Base validate_with_despamilator :attributes => [:some_field] end
When “some_field” is assigned a spammy value, it will add to the errors. For example…
YourModel.new(:some_field => spammy_value).save! #=> ActiveRecord::RecordInvalid exception!
Or…
your_instance = YourModel.new(:some_field => spammy_value) your_instance.save your_instance.errors.full_messages.should #=> ["Some field looks like spam"]
If you want to configure the threshold (which defaults to 1) or add your own callback, you can do the following:
class YourModel < ActiveRecord::Base validate_with_despamilator :attributes => [:some_field], :threshold => 1 do |field, value, despamilator| raise "spam! field: #{field}, value: #{value}, score: #{despamailtor.score}" end end
This example will…
your_instance = YourModel.new(:some_field => "spammy string") your_instance.save! #=> Exception "spam! field: some_field, value: spammy string, score: 123"
The callback will receive the field name, the value and the instance of the Despamilator class.
See the various examples in “spec/fixtures”.
