title: Laravel Eloquent add a prefix to an attribute
body: <p>I have a table with names of districts in my country. Is there a good and easy way to add 'District' string before every name?</p>
  
  <p>There is my table structure:</p>
  
  <pre><code>+------------------------+
  | id | name              |
  +----+-------------------+
  | 1  | Sofia             |
  +----+-------------------+
  | 2  | Shumen            |
  +----+-------------------+
  | 3  | Varna             |
  +------------------------+
  </code></pre>
  
  <p>I need when I call District::find(1)->name to get 'District Shumen'.</p>
