Django 学习笔记之七实现分页

接着上篇，在上篇的基础上实现网页数据分页显示

1、打开views.py，编辑如下

#coding:utf-8
from django.shortcuts import render,get_object_or_404
from blog.models import Post
from django.core.paginator import Paginator,EmptyPage,PageNotAnInteger
# Create your views here.
def post_list(request):
    object_list = Post.objects.all()
    paginator = Paginator(object_list,3)#分页显示,每页3条记录
    page = request.GET.get('page')
    try:
        posts = paginator.page(page)
    except PageNotAnInteger:
        posts = paginator.page(1)
    except EmptyPage:
        posts = paginator.page(paginator.num_pages)
    return render(request,'blog/post/list.html',{'page':page,'posts':posts})

def post_detail(request,post):
    post = get_object_or_404(Post,slug=post)
    # post = Post.objects.get(slug=post)
    return render(request,'blog/post/detail.html',{'post':post})

2、打开urls.py，编辑如下

from django.conf.urls import url,include
from django.contrib import admin
from blog.views import *


urlpatterns = [
    # url(r'^blog/',blog_views.post_list,name='post_list'),
    url(r'^blog/', post_list, name='post_list'),
    url(r'^(?P<post>[-\w]+)/$',
        post_detail, name='post_detail'),
    url(r'^(?P<post_id>)/share/$',post_share,name='post_share'),
    url(r'^admin/', admin.site.urls),
]
