The `urlpatterns` list routes URLs to views. For more information please see: 
    https://docs.djangoproject.com/en/1.9/topics/http/urls/

    2. Add a URL to urlpatterns: url(r'^$', views.home, name='home') 
Class-based views 
    1. Add an import: from other_app.views import Home 
    2. Add a URL to urlpatterns: url(r'^$', Home.as_view(), name='home') 
Including another URLconf 
    1. Add an import: from blog import urls as blog_urls 
    2. Import the include() function: from django.conf.urls import url, include 
    3. Add a URL to urlpatterns: url(r'^blog/', include(blog_urls)) 
""" 
from django.conf.urls import url,include 
from django.contrib import admin 
admin.autodiscover() 

urlpatterns = [ 
    url(r'^admin/', admin.site.urls), 
    url(r'^books/', include('books.urls')),

请更改

def index(request): 
    booklist = Books.objects.all() #Objects changed to objects ; 
    return HttpResponse(booklist)
