def disp开发者_如何学Golay_all_post(request):
   now = datetime.datetime.now()
   posts = Post.objects.all()
   return render_to_response('index.html',{'posts':posts,'now':now})

here is my template

    {% for post in posts.object_list %}
        {{post.title}}
        {{post.body}}
    {% endfor %}

Remove object_list attribute from posts in the template:

 {% for post in posts %}
