У меня есть RegisterForm, который наследуется от ModelForm с RegisterView, который наследуется от FormView.Если все данные поля действительны, пользователь успешно создается и перенаправляется на страницу входа.Но если есть ошибка проверки, она показывает ошибку поля ниже этого поля, и форма обновляется, и все данные полей теряются.Как избежать обновления формы, чтобы пользователю не приходилось заполнять детали снова и снова.
