argparse.ArgumentError:argument--跳过检查:冲突的选项字符串:--跳过检查

Question

我正在使用django租户模式，当我尝试使用"migrate_schemas"命令我遇到一个错误。我在这里看到过类似的问题，但它们根本没有帮助。我在两个不同的应用程序上尝试过，但结果是一样的。有人知道怎么解决这个问题吗？

Answer 1

这是django-tenant-schemas中的一个错误。在阅读Django文档时，他们似乎忘记了将requires_system_checks设置为False。

我相信这个拉取请求会解决问题。

在合并此修复程序之前，您可以通过运行类似的程序将Django降级到版本2来解决此问题

pip install "Django~=2.2"

或者将CCD_ 6列表中的CCD_ 5移动到CCD_。

Answer 2

错误：argparse.ArgumentError: argument --email: conflicting option string: --email
如果有人在这里通过django rest框架的这个错误

因此，出现此错误是因为字段'email'是必需的，但仍在模型的required_FIELDS列表中。

只要将其从REQUIRED_FIELDS中删除，它就可以工作了。

这种情况在其他属性中也是可能的。

class UserAccount(AbstractUser):

first_name = ...
last_name = ...
email = models.EmailField(_("Email address"), unique=True, blank=False)

REQUIRED_FIELDS = AbstractUser.REQUIRED_FIELDS + ['first_name', 'last_name', 'email']
class Meta(AbstractUser.Meta):
swappable = "AUTH_USER_MODEL"
verbose_name = _("UserAccount")
verbose_name_plural = _("UserAccounts")
