Call to undefined method Illuminate\Database\Query\Builder::validate()

[agentready]

This is my admin model -->

<?php

Admin::model('App\Post')->title('All Posts')->with()->filters(function ()
{

})->columns(function ()
{
    Column::string('id','ID');
    Column::string('title','Title');

})->form(function ()
{
    FormItem::text('title', 'Title')->required();
    FormItem::ckeditor('content', 'Content')->required();
});

I got this response -->

 in Builder.php line 2071
at Builder->__call('validate', array(array('_token' => 'iPHgzSoZtK2CCjJhMdgh8EU01rcpulkwJmVysSd5', 'title' => 'Hello world', 'content' => '<p>I am testing</p> '), array('title' => array('required'), 'content' => array('required'))))

I can input database without admin there is no problem.
