Откуда возникла ошибка в модели Django?

0 голосов
/ 28 февраля 2020

Я пытаюсь добавить дополнительные поля для модели User. Команды migrate и makemigrations работали. Когда я пытаюсь создать createuperuser, эта ошибка возникает. Postgresql включен. Я пытался изменить upload_to, добавить «blank = True», «default» к параметрам модели, но ничего не изменилось.

Трассировка: 

  return self.cursor.execute(sql, params)
psycopg2.errors.UndefinedTable: ОШИБКА:  отношение "blog_customuser" не существует
LINE 1: ..._customuser"."age", "blog_customuser"."city" FROM "blog_cust...
                                                             ^


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

    author = models.ForeignKey(User, related_name='posts',on_delete=models.PROTECT)

Ваше поле возраста должно быть таким: 

age = models.PositiveIntegerField(null = True, blank = True)
...
