Question

我正在尝试将以下参数传递给django中的render to response语法，但我不断收到以下错误：

render_to_string（）获得了参数＆＃39; context_instance＆＃39;的多个值。

尝试了不同的解决方案，但仍然没有做到正确。有什么帮助吗？

views.py：

@login_required

def articles(request, everyone=True):

    events = post.objects.filter()
    if request.user.is_authenticated():
        my_events = events.filter(user=request.user) 
        events = events.exclude(user=request.user)
        following = request.user.following_set.all().values_list('to_user', 
            flat=True)
    else:
        my_events = post.objects.none()
        following = None
    if not everyone:
        events = events.filter(user__in=following)

        args = {}
        args.update(csrf(request))
        args ['posts'] = post.objects.filter(user = request.user)
        args ['full_name'] = User.objects.get(username = request.user.username)
        args ['form'] = PostForm()
        args ['forms'] = CommentForm()
        args ['profile_picture'] = request.user.profile.profile_picture

        context = {
        'events': events,
        'my_events': my_events,
        'following': following,
    }


    return render_to_response('articles.html', args, context,
        context_instance = RequestContext(request))

有什么问题吗？

这是来自django source django.template.engine的render_to_string：

def render_to_string(self, template_name, dictionary=None, context_instance=None,
                         dirs=_dirs_undefined):

从(*args,**kwargs)传递render_to_response()来调用它很明显，您的context参数与您分配的关键字参数context_instance冲突。你应该只发送其中一个。也许您应该将context中的数据放在args词典中？

顺便说一下，你可以在这里查看文档： https://docs.djangoproject.com/en/dev/ref/templates/api/#the-render-to-string-shortcut 和这里： https://docs.djangoproject.com/en/dev/topics/http/shortcuts/#render-to-response

render_to_string（）为参数'context_instance'获取了多个值
