мы создали пользовательскую веб-часть для отображения объявлений из всех списков, к которым у пользователя есть доступ, а некоторые из них удалены.Ошибка, которую мы имеем, состоит в том, что веб-часть отлично работает на странице для администраторов, но при тестировании с обычными учетными записями пользователей они вообще не могут видеть страницу и получают ошибку «Отказано в доступе», которая исходит от самой веб-части.
Только когда пользователь добавлен в качестве администратора семейства сайтов, он может видеть страницу и иметь доступ к веб-части.Я хотел бы дать несколько советов о том, как можно применять полные разрешения на чтение к выбранной группе в самом коде.
