I would like to make a timestamp column with a default value of CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP using the Laravel Schema Builder/Migrations. I hav
CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
This is how you do it, I have checked it and it works on my Laravel 4.2.
$table->timestamp('created_at')->default(DB::raw('CURRENT_TIMESTAMP'));
Hope this helps.
