Python 重定向（）无效

重定向函数工作不正常。它正在显示错误

NoReverseMatch at/post/new/Reverse用于带有参数的“post_detail” 未找到“（）”和关键字参数“{'pk'：9}”。已尝试0个模式： []

这是我的观点

使用HttpResponseRedirect而不是重定向函数

from django.http import HttpResponseRedirect

return HttpResponseRedirect(reverse('post_detail', kwargs={'pk':pk}))

也许这应该管用。

不能使用重定向函数传递参数。它仅用于重定向。如果要在重定向时传递参数，HttpResponseRedirect是最好的方法。

可能会很有用。无法进一步提供帮助，因为您还没有显示URL模式。我就是这样做的。但另一个错误是/post/new/name“reverse”处的NameError未定义。请更正它。但另一个错误是，找不到参数“（）”和关键字参数“{pk'：12}”的'post_detail'的NoReverseMatch at/post/new/Reverse。尝试了0个模式：[]您可以发布您的​ url.py。。另外，如果您在“project/urls.py”中使用名称空间，请尝试将HttpResponseRedirect函数相反的url更改为“your_namespace:url_name”。也许它应该起作用..纠正它。我使用了返回重定向（反向（'post_detail'，kwargs={'pk'：pk}））。谢谢你的帮助很高兴我能帮上忙。。。你能帮我个忙，投我一票吗？
