A little app we're going to use to practice MVC

Padrino Jukebox

We're going to write a little app that provides a jukebox service. We're going to draw on what we know about MVC and build on our Sinatra knowledge to create a fuller MVC app in padrino.

INSTALL

• Sign up for SoundCloud (if you've not done so already)

• Create a new app with soundcloud: http://soundcloud.com/you/apps/new. Make a note of what ClientID you have.

• Fork this repo as normal, git clone your own copy.

• cd into your project folder

• Install the padrino gem:

  gem install padrino

• Generate a skeleton MVC app with the following commands:

  padrino g project jukebox -d activerecord -e erb -t shoulda .

• Add the following gems to your gemfile:

  • soundcloud
  • json
  • run bundle

• Generate a controller and model:

  padrino g controller Tracks get:play get:index post:search

  padrino g model Track title:string track_url:string soundcloud_id:integer permalink_url:string artwork_url:string description:string duration:integer genre:string bpm:integer comment_count:integer download_count:integer favouritings_count:integer

• Create a database suitable for the model:

  padrino rake ar:create:all

  padrino rake ar:migrate

• Run padrino server

  padrino s

• Run padrino tests

  padrino rake

TODO

• Add a class method to the Track model, which performs a search for tracks with a given name and returns an array of Track objects. Use your own client ID.

• Add 3 views to your application: app/views/tracks/index.erb, app/views/tracks/search.erb and app/views/tracks/play.erb.

• Rig up your views to the controller, so that the index action shows all tracks, the search action shows a form, which when submitted searches for all tracks, and rig up the play button so that a player is shown when you click on the tracks's title. Use code along these lines for the player:

  Controller: @track = Track.find(params[:id]) client = Soundcloud.new(:client_id => 'YOUR_CLIENT_ID') @sound_cloud_widget = client.get('/oembed', :url => @track.player_url)['html']

  View: <%= @sound_cloud_widget.html_safe %>

• Update your application so that search results are cached to a local database.

• Update your application to display the tracks artwork in the list view. Pretty it up using CSS

• Update your application so that it uses postgresSQL in production and push to heroku

• Update your application so that you can search for titles within given genres.

• If you've got this far, see if you can get pagination to work, read the API docs and see how you might page through results
