• jquery-rails
• kaminari
• ancestry

This generator will required you to have Authentication gems such as Devise, to use this you must include devise and has_messages in your Gemfile.

gem "devise"
gem "has_messages_generators"

After that setup the devise properly.

rails g devise:install
rails g devise user		# => user model name example.

After you configure devise properly now install has_messages with the given USER MODEL NAME

rails g has_messages:install user

this will generate all the necessary files and code into your Rails app.

At the end of the installation just follow the instructions to modify your layout file.

If you wish to add some links for devise and has_messages path, just add this code into your layout file.

<% if user_signed_in? %>
  <%= link_to "inbox(#{current_user.inbox(:opened => false).count})", messages_path(:inbox), :id => "inbox-link" %> |
  Signed in as <%= current_user.email %> Not You?
  <%= link_to 'Sign out', destroy_user_session_path, :method => :delete %>
<% else %>
  <%= link_to 'Sign up', new_user_registration_path %> or <%= link_to 'Sign in', new_user_session_path %>
<% end %>

Run the migration and start the app!
