i am getting

Fatal error: Call to a member function format() on a non-object in D:\ResourceLibrary\Frameworks\Doctrine\lib\Doctrine\DBAL\Types\DateTimeType.php on line 46

Answer 1

The date() function returns a string. The "datetime" type works with DateTime objects. So either change the mapping type to "string" or use DateTime objects.
