Referrer

Referrer tracks sources with which users visit your site, converts them into utm markup, computes priority of these sources and provides linking for sources with tracked model's records (orders/requests/etc).

Sample questions which Referrer can help to answer:

• Where did this user come from?
• {utm_source: 'google', utm_medium: 'organic', utm_campaign: '(none)', utm_content: '(none)', utm_term: 'user search query', kind: 'organic'}
  
  
• Where did users come from last month?
• [{utm_source: 'google', utm_medium: 'organic', utm_campaign: '(none)', utm_content: '(none)', utm_term: 'user search query', kind: 'organic', count: 1}, {utm_source: 'google', utm_campaign: 'adv_campaign', utm_medium: 'cpc', utm_content: 'adv 1', utm_term: 'some text', kind: 'utm', count: 2}, etc...]
  
  
• Where did user who make purchase come from?
• {utm_source: 'twitter.com', utm_medium: 'referral', utm_campaign: '(none)', utm_content: '/some_path', utm_term: '(none)', kind: 'referral'}
  
  
• Where did users who left some requests come from last week?
• [{utm_source: '(direct)', utm_medium: '(none)', utm_campaign: '(none)', utm_content: '(none)', utm_term: '(none)', kind: 'direct', count: 3}, {utm_source: 'google', utm_campaign: 'adv_campaign', utm_medium: 'cpc', utm_content: 'adv 2', utm_term: 'another text', kind: 'utm', count: 5}, etc...]

1. Add Referrer to your Gemfile:

   gem 'referrer'

2. Run the bundle command to install it:

   bundle install

3. Copy migrations from engine:

   rake referrer:install:migrations

4. Migrate your database:

   rake db:migrate

5. Mount engine's routes at config/routes.rb

   mount Referrer::Engine => '/referrer'

6. Require engine's js in your application.js file:

   //= require referrer/application

7. Add to your ApplicationController:

   include Referrer::ControllerAdditions

8. If your current_user method has another name, add to config/initializers/referrer.rb:

   Referrer.current_user_method_name = :your_method_name

Add to your models which objects may be returned from current_user (or your same method, specified in Referrer.current_user_method_name) include Referrer::OwnerModelAdditions. For sample if your current_user return User objects:

class User < ActiveRecord::Base
  include Referrer::OwnerModelAdditions
  #...
end

1. Add to models you want to track include Referrer::TrackedModelAdditions. For sample if you want to track where users who make orders come from (Order class):

   class Order < ActiveRecord::Base
   include Referrer::TrackedModelAdditions
   #...
   end

2. After you create tracked model record next time you can link record with current source. For sample (with Order object):

   # OrdersControllers#create
   #...
   if @order.save
     @order.referrer_link_with(referrer_user) # referrer_user defined in Referrer::TrackedModelAdditions
   else
   #...

Referrer settings can be changed in initializers. For sample, you can create config/initializers/referrer.rb and add your custom settings to it.

5. session_duration - after this duration left, new session will be created and its sources priorities will be computed without regard to past sessions sources.

   3.months

6. sources_overwriting_schema - source's kind priorities for priority source computation.

   {direct: %w(direct),
    referral: %w(direct referral organic utm),
    organic: %w(direct referral organic utm),
    utm: %w(direct referral organic utm)}

Get markups for application user. Returns hash where:

• first - user's first source
• priority - user's last priority source, computed using sources_overwriting_schema
• last - user's last source

user.referrer_markups
=> {first: {utm_source: 'google', utm_medium: 'organic', utm_campaign: '(none)', utm_content: '(none)', utm_term: 'user search query', kind: 'organic'},
    priority: {utm_source: 'google', utm_campaign: 'adv_campaign', utm_medium: 'cpc', utm_content: 'adv 1', utm_term: 'some text', kind: 'utm'},
    last: {utm_source: '(direct)', utm_medium: '(none)', utm_campaign: '(none)', utm_content: '(none)', utm_term: '(none)', kind: 'direct'}}
