Symfony2 Access Booking помощник в команде

Я использую Symfony 2.8 в комплекте с MelifaroBookingBundle, и мне нужно импортировать некоторые данные из CSV с помощью команды. Мне нужно проверить, забронирован ли товар на определенную дату, и выполнить бронирование, если это необходимо.

Согласно документам MelifaroBookingBundle, доступ к помощнику по бронированию можно получить через:

$ This-> Get ( ‘Букер’)

Однако я не могу узнать, как получить доступ к помощнику по бронированию из моей сущности бронирования в моей команде. Кто-нибудь может мне помочь, пожалуйста?

Код моей команды можно найти ниже:
