"Объект" NoneType "не повторяется" при добавлении нового пользователя в пользовательскую модель django
Прежде всего, я новичок в Джанго. Пожалуйста, скажите мне, если мой вопрос не ясен и не прост.
Я пытался создать пользовательскую модель для своего приложения, все было нормально, пока я не обнаружил ошибку при попытке добавить нового пользователя на странице администратора. Страница ошибки была показана после того, как я нажал кнопку "Добавить пользователя" в правом верхнем углу страницы.
*Заметка:
- Я использую Django 1.10.8
- Я создал его в приложении под названием "учетные записи"
- Я пытаюсь избавиться от поля имени пользователя (по умолчанию в Django) и изменил его на phone_number как уникальное поле.
- Я могу создать суперпользователя (с помощью Python manage.py создает суперпользователя), я также могу редактировать его.
Это ошибка:

Любая помощь будет оценена. Спасибо.

Решение
Я думаю, вам нужно добавить запятую после первого кортежа, в add_fieldsets, Попробуйте скопировать следующий фрагмент кода.
add_fieldsets = (
(None, {
'classes': ('wide',),
'fields': ('phone_number', 'password1', 'password2')
}),
)
Проверил это в консоли:
>>> from django.contrib.admin.utils import flatten_fieldsets
>>> add_fieldsets = ((None, {'classes': ('wide',), 'fields': ('phone_number', 'password1', 'password2')}))
>>> flatten_fieldsets(add_fieldsets)
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/home/yauheni/Dev/clean_django/venv/lib/python3.6/site-packages/django/contrib/admin/utils.py", line 112, in flatten_fieldsets
for name, opts in fieldsets:
TypeError: 'NoneType' object is not iterable
>>> add_fieldsets = ((None, {'classes': ('wide',), 'fields': ('phone_number', 'password1', 'password2')}),)
>>> flatten_fieldsets(add_fieldsets)
['phone_number', 'password1', 'password2']
>>>
UPD
Это скорее проблема с питоном, а не с Джанго. Так что вы не найдете ответа в документации Django. Вот функция, где была ошибка. Чтобы дать вам идею, я оставлю этот пример:
>>> x = ((1, 2))
>>> x[0]
1
>>> x = ((1, 2),)
>>> x[0]
(1, 2)
