Rails 3 -> Ahoy plugin for user activity tracking

I have installed the Gem Ahoy as per the instruction in the link -> http://ift.tt/1euzW8q

Add this line to your application’s Gemfile:

gem 'ahoy_matey'

And add the javascript file in app/assets/javascripts/application.js after jQuery.

//= require jquery
//= require ahoy

MySQL or SQLite

Add activeuuid to your Gemfile.

gem 'activeuuid', '>= 0.5.0'

And run:

rails generate ahoy:stores:active_record
rake db:migrate

The visit.rb module gets created fine but on rails console, I get 'Table doesn't exist' error

Visit
 => Visit(Table doesn't exist) 

How can I configure Ahoy with my Ruby application
