/ 28 мая 2019

В моем проекте три таблицы базы данных.Когда я применяю миграции, они применяются успешно и также видны на сайте администратора.Но когда я нажимаю на одну из трех таблиц базы данных на сайте администратора, я получаю сообщение об ошибке, в котором говорится, что таблица не существует.Остальные две таблицы работают правильно.Я попытался удалить папку миграций и снова применить миграцию.Но та же ошибка повторяется.Ошибка выглядит следующим образом: 

Internal Server Error: /admin/users/subscription/

The above exception was the direct cause of the following exception:

Ошибка возникает при нажатии на таблицу подписок на сайте администратора.'users' - это имя моего приложения.

Когда я применяю миграцию, отображается следующее.Исходя из этого, я могу убедиться, что таблица Subscription создана.
