DB::table('menu_types')->insert([ 'title' => 'Footer', 'description' => str_random(10), 'created_at' => date("Y-m-d H:i:s") ]);
---------------------
Auto timestamp saving is only for Eloquent feature so you need to do manually like below for non eloquent feature
DB::table('languages')->insert([
'name' => 'English',
'flag' => '',
'abbr' => 'en',
'script' => 'Latn',
'native' => 'English',
'active' => '1',
'default' => '1',
'created_at' => Carbon::now()->format('Y-m-d H:i:s'),
'updated_at' => Carbon::now()->format('Y-m-d H:i:s')
]);
OR do it eloquently(Like you have seen in auto generated seeds like UserTableSeeder)
$language = new Language();
$language ->name = 'English';
$language->flag' = '',
$language ->abbr = 'en',
$language->script ='Latn',
$language->native ='English',
$language->active ='1',
$language->default ='1',
$language->save();
