Question

我更新帖子后，我想重定向回我的详细信息页面。但它不起作用。继承人我的网址

 url(r'^(?P<id>\d+)/$', post_detail, name='detail'),

这是我的观点

def post_update(request, id=None):
instance = get_object_or_404(Post, id=id)
form = PostForm(request.POST or None, instance=instance)
if form.is_valid():
    instance = form.save(commit=False)
    instance.save()
    return HttpResponseRedirect(reverse('posts:list', args=id))

context = {
    "title": instance.title,
    "instance": instance,
    "form": form
}
return render(request, "posts/post_form.html", context)

这是我收到的错误消息

Reverse for 'list' with arguments '('3',)' and keyword arguments '{}' not found. 1 pattern(s) tried: ['posts/$']

我也试过改变这个

 return HttpResponseRedirect(reverse('posts:list', args=id))

到这个

 return HttpResponseRedirect(reverse('posts:list', args=instance.id))

和

 return HttpResponseRedirect(reverse('posts:list', args=Post.id))

如何更正

Answer 1

您是重定向到list网址，但是想要重定向到detail？

return HttpResponseRedirect(reverse('posts:detail', args=id))

使用HttpResponseRedirect更新后如何正确返回details.html
