Python NoReverseMatch at/signup/-与#x27相反&书信电报；WSGIRequest:POST'/注册'&燃气轮机'；找不到

我正在做的项目是博客网站，我被困在这个注册过程中，我希望它的功能就像注册后，用户登陆到主页上，但这显示了我上面的错误

return redirect(request, "/home.html")

您在

url.py

中指定了

path（“，views.home，name=“home”）

，因此您可以执行以下操作：

return redirect("/")

您不应该将

请求

作为第一个参数传递给

重定向（）

，您只需要在大多数情况下提供URL（相对或绝对）

实际上，作为一种最佳实践，该URL应使用

反向提供，例如：

from django.urls import reverse
...
return redirect(reverse('home'))
