the test task rails tracking user system

Implement simple rails store app with abilities to track user's activities

Features:
  - product has title, description, price, tags
  - pages: list of products, product's detail page
  - search by products(use mysql)
  - track user's clicks by the product in the search results
  - every user should have unique tracking code. Use cookies to set it.
  - save product id, user's ip, search keywords, user-agent, user's geo location, user's tracking code
  - page: the list of tracking clicks

Please, use mysql, haml or slim, rails 3 or 4, ruby 2.0 or higher. 
Don't spend too much time on UI. More important the code quality.
Ready application should be published to your github and send link to me.
