title: Linking Models Together
body: <p>I have the following three tables in a database:</p>
  
  <pre><code>Products
  ********
  id
  title
  artist_id
  
  Artists
  *******
  id
  profile
  rating
  person_id
  
  People
  ******
  id
  first_name
  last_name
  </code></pre>
  
  <p>Each artist can have many products.</p>
  
  <p>Each artist has only one person.</p>
  
  <p>Each product has only one artist.</p>
  
  <p>What are the correct associations to set up between the models for these three tables?</p>
