Communication between models?

Question

Ruby on Rails

There are two models Album, Song
How to do what would when you navigate through Album - give a list of Song to it.
album.rb(models)

class Album < ActiveRecord::Base
  has_many :songs
end

song.rb(models)

class Song < ActiveRecord::Base
  belongs_to :album
end

As I understand it, you need to look towards the show action in the Album controller

Answer 1

The next step is described here.
You need to add to the album controller

def show
@album = Album.find(params[:id]) 
@songs = @album.songs
end

and in show views

<% @songs.each do |song| %>
<%= link_to song.name, song %>
<% end %>

Answer 2

You understand correctly.
