title: Laravel Eloquent Relationship without key
body: <p>How do I eager load another model in eloquent? The relationship isn't exactly a relationship in the traditional sense, it's a requirement.</p>
  
  <p>I have a <code>users</code> table, and a <code>target_types</code> table. Every <code>user</code> will have all of the same <code>target_types</code>. So whatever <code>target_types</code> are present in the <code>target_types</code> table, will apply to all <code>users</code>. So there's no need for a foreign key type of relationship.</p>
  
  <p>I realise I could go down the query builder route, however ideally I'd love to be able to do something like:</p>
  
  <pre class="lang-php prettyprint-override"><code>User::with('target_types')-&gt;get();
  </code></pre>
  
  <p>Any ideas?</p>
