Page Wrapper helps you add pagination to a list of resources fetched from a Rails server and rendered using Ember and Ember Data.

It contains:

• a page model class intended to be extended to wrap a list of resources into a page
• a set of Ember classes to help fetching, browsing, sorting and filtering the list of resources within an Ember application
• a generator for all the Ruby and CoffeeScript files you need to paginate those resources

It requires a 3.1+ rails or rails-api application and a model to paginate. There are no constraint on which ORM or plain old Ruby object to use, or which tool to paginate or filter on the Ruby side. It is up to you to code or integrate that part (i.e.: Active Record + Kaminari, Mongoid + Kaminari, Remotely + Kaminari, etc...).

Finaly it is delegating most of the work to a set of great Ruby gems and JavaScript libraries:

• Rails API or Rails for the web server
• Active Model Serializers to serialize the page instance and its collection
• Ember Rails that comes with Ember and Ember Data for fetching the data from the browser and rendering the collections and browse it page by page

Page Wrapper works with Rails 3.1 onwards and Ember Rails 0.6.0+.

Add this line to your application's Gemfile:

gem 'page_wrapper'

And then execute:

$ bundle

After you install Page Wrapper and add it to your Gemfile, you need to run the generator. Assuming you want to paginate Movie resources:

rails generate page_wrapper:page movie

This command will generate the Ruby and Ember classes required to paginate a Movie model and add a route to the index action of the new server movie page controller.

At that point you just need to update your Ember application routing manager to route to the new front-end movie page controller. Here is an example of a single page with an outlet setup to contain the list of movies:

# app/assets/javascripts/routes/app_router.js.coffee

App.Router = Ember.Router.extend
  location: 'hash'

  root: Ember.State.extend
    index: Ember.State.extend
      route: '/'
      connectOutlets: (router) ->
        controller = router.get('applicationController')
        controller.connectOutlet(App.MoviePageView, App.MoviePageController::firstPage())
        moviePageController = router.get('moviePageController')
        moviePageController.set('target', moviePageController)

After reloading your application you should now look at the first page and be able to interact with the pagination control to navigate the collection page by page.
