Пользовательский пользователь не может войти

Question

Я создал пользовательскую модель для «дилеров» и «сотрудников». После создания «дилерской» модели я не могу войти в систему. Я пробовал как свою форму «учетные записи / вход», так и страницу / admin. Когда я пытаюсь войти в систему, появляется сообщение: «Пожалуйста, введите правильный адрес электронной почты и пароль для учетной записи персонала. Обратите внимание, что оба поля могут быть чувствительны к регистру.
