NOTE his plugin requires the private e9_base CMS gem and WILL NOT WORK without it.

CRM Plugin for the e9 CMS

To use, add as a gem and install by running:

rails g e9_crm:install

Then modify the installed initializer as per your app, including the controller module in your desired controllers, with the final result looking something like this:

require 'e9_crm'

User.send :include, E9Crm::Backend::ActiveRecord

Rails.configuration.after_initialize do
  [
    MyFirstTrackedController,
    MySecondTrackedController
  ].each {|c| c.send(:include, E9Crm::TrackingController) }
end

NOTE: A few assumptions are made:

1. Your app has a "User" model
2. Your app has a controller method #current_user to return the currently logged in user.
