title: Laravel 5.2 show saved date in edit form
body: <p>This is probably a really, really simple issue, but it's got me stumped...</p>
  
  <p>So, I've got an article saved in the database with a form, including a field to save a published date.  The data entered in this field is successfully saving in the database, along with the rest of the data.</p>
  
  <p>I'm successfully pulling all the saved data back out into the edit form, EXCEPT the published_date field.   </p>
  
  <p>I've tried using the same format as the other fields, eg title, both show below</p>
  
  <pre><code>{!! Form::text('title', null) !!}
  {!! Form::input('date', 'first_published', null) !!} 
  </code></pre>
  
  <p>This puts dd/mm/yy in the input box, rather than the saved date.  If this value isn't changed, the date is saved in the database as today's date.</p>
  
  <p>I've also tried removing the 'date' attribute</p>
  
  <pre><code>  {!! Form::input('first_published', null ) !!}
  </code></pre>
  
  <p>This results in a totally empty box (and no datepicker), which doesn't overwrite the value in the form if not saved.  Better, but still not what I want, as I want to show the saved date, which can be changed if required.</p>
  
  <p>I've also tried echoing the $article->published_date in various ways in this field, but only end up with the same results as those above.  I can echo out this data elsewhere in the form no problem though using {!! $article->first_published !!} </p>
  
  <p>The form references the model as so:</p>
  
  <pre><code>{!! Form::model($article, ['method' =&gt; 'PATCH', 'url' =&gt; 'articles'.'/'. $article-&gt;id]) !!}
  </code></pre>
  
  <p>And the relevant controller functions are</p>
  
  <pre><code>   //page containing form to edit article, pulls in existing data
  public function edit($id)
  {
      $article = article::findOrFail($id);
  
      return view('articles.edit', compact('article'));
  }
  
  //responsible for updating the article record
  public function update($id, Request $request)
  {
      $article = article::findOrFail($id);
      $article-&gt;update($request-&gt;all());
  
      return redirect('articles');
  }
  </code></pre>
  
  <p>The field is set as a timestamp in the migration, and in the model I have</p>
  
  <pre><code>protected $dates = [
      'first_published'
  ];
  </code></pre>
  
  <p>So, if anyone can shed any light on how to get the saved data value into the form field as in the other fields, it would be much appreciated! :)  I'm pretty new to laravel so apologies if there's some blindingly obvious issue I've missed... </p>
