title: Doctrine 2 - One-to-Many unidirectional
body: <p>A couple questions regarding creating a One-to-Many unidirectional relationship in Doctrine 2:</p>
  
  <ol>
  <li>Is a join table necessary?</li>
  <li>The <a href="http://docs.doctrine-project.org/projects/doctrine-orm/en/2.0.x/reference/association-mapping.html#one-to-many-unidirectional-with-join-table" rel="nofollow">docs</a> say "look at this example," but all I see is the generated schema.  Anyone mind whipping up a quick example so I can get the annotations correct?</li>
  </ol>
