title: Error when using the format: $table->date('column_name') in Laravel
body: <p>I'm having some trouble with date formats in Laravel.
  I have a database migration which has a field that looks like the following:</p>
  
  <pre><code>$table-&gt;date('Date');
  </code></pre>
  
  <p>Then, in the controller, I try to fill this field in with the following content:</p>
  
  <pre><code>2019-04-15
  </code></pre>
  
  <p>But I get the following error:</p>
  
  <pre><code>invalid datetime format: 1292 Incorrect date value: '"2019-04-15"' for column 'Date' at row 1
  </code></pre>
  
  <p>Any help on which would be the correct way of declaring the field 'Date' in the database would be apreciated.</p>
  
  <p>Thank you very much in advance.</p>
