title: Cannot fetch data with hasMany eloquent relationship?
body: <p>I'm trying to learn eloquent relationships. My relation is something like:
  Users hasMany posts and a post belongs to a user.</p>
  
  <p><strong>when I run my queries in tinker it shows errors.</strong></p>
  
  <pre><code>$user-&gt;new User();
  $user-&gt;all(); //Displays all the users
  but i cannot do
  $user-&gt;all()-&gt;posts;
  </code></pre>
  
  <p><strong>it returns an empty array</strong>
  <strong>but If I do something like:</strong></p>
  
  <pre><code>$posts = new Post();
  $posts-&gt;all();
  $post-&gt;users;
  </code></pre>
  
  <p><strong><em>Error: Exception with message 'Property [post] does not exist on this collection instance.'</em></strong></p>
  
  <p>How can I achieve something like I want to have the users associated with posts or precisely I want users who have written posts. </p>
