Question

我应该说我是Django noob！我创建了一个DeveloperManager（）管理器类和一个Developer（）模型类。我正在尝试使用

在数据库中创建开发人员记录

d = Developer.objects.create_default_developer("a test name", "username", "1234", "email@example.com")

但它失败了

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/Users/user/Desktop/Projects/project/engine/models.py", line 9, in create_default_developer
    def create_default_developer(self, developer_name, username, password, email):
  File "/Users/user/.virtualenvs/project/lib/python2.7/site-packages/django/db/models/manager.py", line 92, in manager_method
    return getattr(self.get_queryset(), name)(*args, **kwargs)
TypeError: create() takes exactly 1 argument (5 given)

这里到底出了什么问题？我想我已经正确设置了所有参数，但这仍然失败。

我的代码如下：

class DeveloperManager(models.Manager):

    def create_default_developer(self, developer_name, username, password, email):
        developer = self.create(developer_name=developer_name, username=username, password=password, email=email)
        return developer


class Developer(models.Model):

    developer_name = models.CharField(max_length=120)
    username = models.CharField(max_length=120)
    password = models.CharField(max_length=200)
    email = models.EmailField()
    billing_email = models.EmailField()
    created = models.DateTimeField('date created')
    updated = models.DateTimeField('date updated')


    @classmethod
    def create(cls, developer_name, username, password, email):
        developer = cls(developer_name, username, password, email)
        developer.save()
        return developer

    objects = DeveloperManager()

提前感谢您的帮助。

编辑：在developer = Developer(developer_name=developer_name, username=username, password=password, email=email)中使用create_default_developer()，它成功创建了对象。但这是否是使用经理的正确方法？如果是的话，我完全可以接受。如果不是，我该怎么做才能正确使用django经理？

无法使用对象管理器在Django中创建模型实例
