当我要进入汽车页面时，出现错误:::（（/ cars /中的NoReverseMatch） 和 （未找到与“登录”相反的名称。“登录”不是有效的视图函数或模式名称。）
有人可以帮助我吗？ 请帮助我！！！!!!

尝试将您的汽车和用户网址包含在基本urls.py中。
from yourproject.cars import urls as car_urls
from yourproject.users import urls as users_urls
，然后将以下内容添加到您的基本网址模式
url(r"^cars/", include((car_urls)),
url(r"^users/", include((user_urls)),
