请教大神出现这种报错，如何修改。context must be a dict rather than RequestContext

Django源码如下： from django.core.mail import EmailMessage from django.template import RequestContext from django.template import Context, Template from django.template.loader import get_template from django.http import HttpResponse, HttpResponseRedirect from mysite import models, forms

def index(request, pid=None, del_pass=None): template = get_template('index.html')

posts = models.Post.objects.filter(enabled=True).order_by('-pub_time')[:30]
moods = models.Mood.objects.all()
try:
    user_id = request.GET['user_id']
    user_pass = request.GET['user_pass']
    user_post = request.GET['user_post']
    user_mood = request.GET['mood']
except:
    user_id = None
    message = '如要张贴信息，则每一个字段都要填...'

if del_pass and pid:
    try:
        post = models.Post.objects.get(id=pid)
    except:
        post = None
    if post:
        if post.del_pass == del_pass:
            post.delete()
            message = "数据删除成功"
        else:
            message = "密码错误"
elif user_id != None:
    mood = models.Mood.objects.get(status=user_mood)
    post = models.Post.objects.create(mood=mood, nickname=user_id, del_pass=user_pass, message=user_post)
    post.save()
    message='成功保存！请记得你的编辑密码[{}]!，信息需经审查后才会显示。'.format(user_pass)
