推荐答案

如果我清楚地理解了您的问题，那么
您的视图应该类似于。

If I understand your question clearly then Your view should be something like.

def add_comments(request):
    if 'application/x-www-form-urlencoded' in request.META['CONTENT_TYPE']:
        print 'hi'
        data = json.loads(request.body)
        comment = data.get('comment', None)
        id = data.get('id', None)
        title = data.get('title', None) 

        post = Post.objects.get(id = id)
        com = Comment()
        com. comments = comment
        com.title = post
        com.save()
