Я потратил часы, пытаясь понять, как передавать данные между контроллерами. Может кто-нибудь, пожалуйста, помогите мне?AngularJS, передающий данные между контроллерами

Я пытаюсь передать информацию об объекте пользователя от RootController к контроллеру ViewProfile.
Я думаю, что проблема, с которой я могу столкнуться, заключается в том, что переключение вида может привести к уничтожению переменной?
Может кто-нибудь указать мне в правильном направлении?
Вот layout.jade, который использует RootController:

Я предполагаю, что маршрут 'user/profile /' является тем, который использует 'ViewProfileController'? – tasseKATT
Да, это так. Это верно. – rgins16
Просто для тестирования увеличьте таймаут внутри 'setSearchedUser' до 5000 и посмотрите, что произойдет. – tasseKATT
