Ссылаясь на изображение ниже.Если я хочу создать модуль для отображения всей информации о событиях, таких как registerEventName, registerEventLocation .... Как это сделать?Во второй строке указан идентификатор созданного события, за которым следует идентификатор события.Заранее спасибо.Я хочу отобразить всю информацию из списка событий, созданного всеми пользователями. Скажите, пожалуйста, нужна ли была какая-либо дополнительная информация.
