表单POST后重定向重新加载当前页面视图

在一个简单的博客应用程序中,当用户对帖子发表评论时,建议的方法是重定向到同一个变量路由或永久链接以显示新评论(在django中)?

urlpatterns = [
    ...
    url(r'^comments/(?P<post_id>[0-9]+)$', views.comments, name="thread"),
    url(r'^post/comment/$', views.post_comment, name="post_comment"),
]

在视图中,我可以使用request.get_full_path()获取网址,但我认为不是剥离post_id,而是将更好的方式传递给重定向。示例视图(但不是正确的):

def post_comment(request):

   author = User.objects.get(user=request.user)
   new_comment = request.POST.get('commentContent', None)
   parent_object = None
   comment = Comment.create(author=author,
                            new_comment=new_comment,
                            parent=parent_object)

   comment.save()
   return redirect('/comments/{}'.format(comment.post.id))

提交评论表格将记录:

[28/Feb/2017 05:21:33] "POST /post/comment/ HTTP/1.1" 302 0
[28/Feb/2017 05:21:33] "GET /comments/{{post_id}} HTTP/1.1" 200 44831

并且表单正确发布,但页面不会重新加载/重定向

感谢

您可以使用反向重定向:

from django.core.urlresolvers import reverse

# at the end of your view
redirect_to = reverse('blog:thread', kwargs={'post_id': post.id})
return redirect(redirect_to)
