Вопрос:
эй, я работаю над каким-то проектом, теперь я хочу добавить поля IP-адреса в каждую модель
ip_address = модели.GenericIPAddressField()
добавляя вот так, теперь, когда я переношу его, я получаю ошибку, подобную этой
если значение и ‘:’ в значении: TypeError: аргумент типа ‘int’ не может быть повторен
0005_remove_documentvault_ip_address
class Migration(migrations.Migration):
dependencies = [
('master', '0005_remove_documentvault_ip_address'),
]
operations = [
migrations.AddField(
model_name='documentvault',
name='ip_address',
field=models.GenericIPAddressField(default=1),
preserve_default=False,
),
]

Ответ №1:
Миграция (и, возможно, ваша модель тоже) имеет default=1
. Это недопустимый IP-адрес.
Вы можете либо заменить значение по умолчанию в вашей модели на действительный IP-адрес, либо удалить значение по умолчанию и установить null=True
.
Затем удалите 0006
миграцию (сначала создайте резервную копию для обеспечения безопасности или убедитесь, что она находится в системе управления версиями). Наконец, повторно запустите makemigrations и выполните миграцию.
