Попробуйте показать таблицу с кнопками действий - laravel 5.3 и dataTables.min.js

Question

Я новичок в laravel 5.3, и я учусь, но у меня есть проблема, с которой я не могу решить, может быть, кто-то может мне помочь. Я хочу показать таблицу (около) с помощью некоторых кнопок действий. Когда я просматриваю index.blade, я получаю excetion в своих журналах и не вижу таблицу. No table

С помощью инструмента разработки от хром я получаю статус 500.

Answer 1

Потратив несколько часов отладки я мог найти ошибку: D

Я forgott, чтобы получить запрос от функции __construct в AboutTableController. Без этого $ this-> about в строке 26 возвращает null. После этого и несколько модификаций это сработало :)

public function __construct(AboutRepository $abouts) 
{ 
    $this->abouts = $abouts; 
}
