django.contrib.auth.models.DoesNotExist : User matching query does not exist

Question

我尝试使用以下命令在 python shell 中创建用户实例。

from django.contrib.auth.models import User
User.objects.all()
<QuerySet [<User: admin>]>
me = User.objects.get(username='rohan')

之后我得到了以下错误。有人可以帮忙吗。

 Traceback (most recent call last):
      File "<console>", line 1, in <module>
      File "C:\Users\Rohan Jain\AppData\Local\Programs\Python\Python36\lib\site-packages\django\db\models\manager.py", line 85, in manager_method
        return getattr(self.get_queryset(), name)(*args, **kwargs)
      File "C:\Users\Rohan Jain\AppData\Local\Programs\Python\Python36\lib\site-packages\django\db\models\query.py", line 380, in get
        self.model._meta.object_name
    django.contrib.auth.models.DoesNotExist: User matching query does not exist.

Answer 1

你有no User with username rohan .不过，您似乎有一个用户名为 admin 的用户。

me = User.objects.get(username='admin')
