У меня довольно простое приложение, которое я использую с помощью углового метеор. Ниже приведен файл app.js. Когда пользователь входит в систему, они перенаправляются в исходное состояние. Обычно существует $ rootScope.currentUser, и я могу получить данные пользователя, которые мне нужно отображать в представлениях, и т. Д. Однако иногда при обновлении я получаю сообщение об ошибке: $ rootScope.currentUser не определен. Я почти уверен, что коллекция пользователей Meteor иногда еще не готова, когда я пытаюсь получить к ней доступ, но я не могу понять, как это сделать каждый раз.
