Ошибка миграции Django, дублированный ключ auth_permission_content_type_id_codename_01ab375a_uniq

Question

Я пытаюсь перенести мой модуль в PostgresSQL, но когда я это делаю, я получаю сообщение об ошибке, сообщающее мне, что уникальный ключ auth_permission_content_type_id_codename_01ab375a_uniq дублируется.ключ (content_type_id, codename) = (1, view_arrets) существует.Код как-то создает дубликаты представлений.мои модули:
