Respond to Custom Formats in Rails

Respond to Custom Formats in Rails 4

Posted by arunagw on October 24, 2011

We usually respond some of the known formats in Rails Application like HTML, XML, JavaScript, RSS and some custom.

Have you tried to use your own custom format for your Rails Application?

Yes you can use your custom format in Rails Application.

Here showing a simple Rails Application with responding custom formats.

Get a new app

rails new music_library

Get a scaffold into App

rails generate scaffold mp3 title:string url:string description:text

Ok so you are ready to serve some music on your app with some formats!

Now you have to register MIME types in the Rails Application.

For that open up Rails.root/config/initializers/mime_types.rb

Mime::Type.register 'audio/mpeg' , :mp3

Now you can serve .mp3 and content

For that your respond block should look like

def show
  @mp3 = Mp3.find(params[:id])
  respond_to do |format|
    format.mp3 { redirect_to @mp3.url }
  end
end

Now if you call this action with .mp3

http://localhost:3000/mp3s/1.mp3

You will redirect_to @mp3 url.


Happy adding custom formats!!

maybe you could use send_file to show the mp3 file directly in the same resource. The redirect part dont make sense.
respond_to do |format|
format.mp3 { send_file @mp3.url, :type => ‘audio/mpeg’, :disposition => ‘inline’ }end

Nice! I like how you’ve created a simple example from scratch – makes it easy to try this myself

Is there a way to render an MP3 file requested from a RoR server for a non-web app(Android app) ? I want to stream a music file in the server from the app.
