Hi,
I'm using Laravel 5.2 and I was unable to insert row if the table of my model was empty.
I found the fix in DatatablesEditor.php
line 84 replace inside else statement: $model = $model::all(); by $model = new $model;
and line 88: $model[0]->create($input['data'][$rowFirstId]); by $model->create($input['data'][$rowFirstId]);
I
