title: Alias for a route with a fixed parameter value
body: <p>I have this route:</p>
  
  <pre><code>Route::get('/MyModel/{id}', 'MyController@show');
  </code></pre>
  
  <p>The method <code>show()</code> accepts a parameter called <code>id</code> and I want to setup an alias for <code>/MyModel/1</code> so it's accesible from <code>/MyCustomURL</code>.</p>
  
  <p>I already tried a few combinations, like:</p>
  
  <pre><code>Route::get('/MyCustomURL', ['uses' =&gt; 'MyController@show', 'id' =&gt; 1]);
  </code></pre>
  
  <p>But I keep getting <em>missing required argument</em> error for method <code>show()</code>.</p>
  
  <p>Is there a clean way to achieve this in Laravel?</p>
