argparse.ArgumentError：参数 --skip-checks：

Question

我正在使用 django-tenant-schemas，当我尝试使用“migrate_schemas”命令时遇到错误。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，但结果是相同的。有人知道如何解决这个问题吗？

Answer 1

这是 中的一个错误django-tenant-schemas。从阅读 Django 文档来看，他们似乎忘记设置requires_system_checks为False.在合并此修复之前，您可以Django通过运行以下命令降级到版本 2 来解决此问题pip install "Django~=2.2"或将列表移至tenant-schemas文件INSTALLED_APPS底部settings.py。

Answer 2

错误：argparse.ArgumentError: argument --email: conflicting option string: --email如果有人遇到 django-rest-framework 的此错误因此，出现此错误是因为字段“电子邮件”是必需的，但仍在模型的REQUIRED_FIELDS列表中。只需将其从REQUIRED_FIELDS中删除，它就应该可以工作。这种情况在其他属性中也可能发生。class UserAccount(AbstractUser):&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; first_name = ...&nbsp; &nbsp; last_name = ...&nbsp; &nbsp; email = models.EmailField(_("Email address"), unique=True, blank=False)&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; REQUIRED_FIELDS = AbstractUser.REQUIRED_FIELDS + ['first_name', 'last_name', 'email']&nbsp; &nbsp; class Meta(AbstractUser.Meta):&nbsp; &nbsp; &nbsp; &nbsp; swappable = "AUTH_USER_MODEL"&nbsp; &nbsp; &nbsp; &nbsp; verbose_name = _("UserAccount")&nbsp; &nbsp; &nbsp; &nbsp; verbose_name_plural = _("UserAccounts")
