спасибо. Мне нужна помощь.
Я строю приложение чата в действии.
Как и в обычном пользовательском интерфейсе чата, если вы хотите отобразить свое собственное сообщение справа, вам необходимо определить, кто это сказал
Несмотря на то, что несколько пользователей и комнат связаны, в одно время могут быть объединены только определенные комнаты.
Меня беспокоит следующая ошибка.
[ActiveJob] [MessageBroadcastJob] [20011496-6735-40ae-af0c-98abc36a125b] Error performing MessageBroadcastJob (Job ID: 20011496-6735-40ae-af0c-98abc36a125b) from Async(default) in 2175.61ms: ActionView::Template::Error (undefined method `generate_key' for nil:NilClass):
Происходит при использовании метода current_user в представлении.
Я настроил в соответствии с документом для удобства использования
module ApplicationCable
class Connection < ActionCable::Connection::Base

def connect
self.current_user = find_verified_user
end

verified_user
else

end
end
def session
cookies.encrypted[Rails.application.config.session_options[:key]]
end
end
end
Подтверждено, что cookies.encrypted[Rails.application.config.session_options[:key]] может получить идентификатор пользователя, но текущий пользователь недоступен.
