AnonymousUser对象¶

class models.AnonymousUser¶

django.contrib.auth.models.AnonymousUser是一个实现django.contrib.auth.models.User接口的类，具有以下差异：

• id始终是None。
• username 永远是空字符串。
• get_username() 总是返回空字符串。
• is_anonymous是True 不是False。
• is_authenticated是 False不是True。
• is_staff并且 is_superuser永远 False。
• is_active永远False。
• groups并且 user_permissions总是空的。
• set_password()， check_password()， save()和 delete()提高NotImplementedError。
