Django使用OnetoOneField创建数据

Question

您好，谢谢您的时间：

我正在尝试通过管理/命令/create_data.py向我的模型表中添加一些数据：

1º问题

在我的另一个项目中，我可以打电话给python manage.py create_data create_data.py，尽管在这个项目中没有用。如何调用正确的命令？

2º问题

除了我想我会在People模型的用户字段上收到错误，因为它应该是一个ID。我如何获取ID？

pets / models.py：

User = get_user_model()



class People(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='person')
    birthday = models.DateField()
    cpf = models.CharField(max_length=11, validators=[RegexValidator(r'^\d{1,10}$')])

    def __str__(self):
        return '%s' % (self.user)

宠物/管理/命令/create_data.py：

User = get_user_model()


class GenerateUser():
    username = None
    password = None
    def __init__(self, username, password):
        with open('User.txt') as file:
            for rows in file:
                self.username = slugify(rows)
                self.password = '12345'


class GeneratePeople():
    user = None
    documento = None
    birthday = None
    def __init__(self, documento, birthday):
        with open('People.txt') as file:
            for rows in file:
                t1 = rows.split(', ')
                self.user = slugify(t1[0])
                self.documento = t1[1]
                self.birthday = t1[2]



class Command(BaseCommand):

    def add_arguments(self, parser):
        parser.add_argument(
            'file_name', type=str, help='ok')

    def handle(self, *args, **kwargs):

        username = GenerateUser.username
        password = GenerateUser.password
        user = GeneratePeople.user
        documento = GeneratePeople.documento
        birthday = GeneratePeople.birthday

        one = User(
            username=username,
            password=password
            )

        one.save()

        peop = People(
            user=user,
            documento=documento,
            birthday=birthday
        )

        peop.save()


        self.stdout.write(self.style.SUCCESS('Data imported successfully'))

People.txt：
