ОшибкаException в строке PlaceController.php 101: попытка получить свойство не объекта - Laravel 5.1 *

Question

Я пытаюсь создать страницу, где пользователь может поместить некоторые данные и сохранить или опубликовать их. Но когда я пытаюсь посетить мое место добавление URL я получаю сообщение об ошибке "ErrorException в PlaceController.php линии 101: Попытка получить свойство не-объект"

Мой маршрут:

Answer 1

Ваш чек на if(!$place) принадлежит, прежде чем использовать $place->div_id.

Возможно, что $place = Places::where('slug',$slug)->first(); не возвращает модель.
