bootstrap实现分页按钮–>设计分页url–>使用django分页组件实现分页功能
index.html修改如下：
<html lang="en">
<head>

clo-md-4 col-md-offset-3表示占4列，偏移3
视图函数views.py中如下：
使用Django自带的paginator分页
from django.core.paginator import Paginator
def get_index_page(request):
page = request.GET.get('page')
if page:
page = int(page)
else:
page = 1
all_article = Article.objects.all()
paginator = Paginator(all_article, 2)
page_num = paginator.num_pages
page_article_list = paginator.page(page)
if page_article_list.has_next():
next_page = page + 1
else:
next_page = page
if page_article_list.has_previous():
previous_page = page - 1
else:
previous_page = page
return render(request, 'blog/index.html',
{
'article_list': page_article_list,
'page_num': range(1, page_num + 1),
'curr_page': page,
'next_page': next_page,
'previous_page': previous_page
})
Python manage.py runserver启动项目查看如图：
14最后一个功能啦—最近文章
方法就是利用发布时间倒序排序
def get_index_page(request):
page = request.GET.get('page')
if page:
page = int(page)
else:
page = 1
all_article = Article.objects.all()
top_article_list = Article.objects.order_by("-publish_data")[:2]
paginator = Paginator(all_article, 2)
page_num = paginator.num_pages
page_article_list = paginator.page(page)
if page_article_list.has_next():
next_page = page + 1
else:
next_page = page
if page_article_list.has_previous():
previous_page = page - 1
else:
previous_page = page
return render(request, 'blog/index.html',
{
'article_list': page_article_list,
'page_num': range(1, page_num + 1),
'curr_page': page,
'next_page': next_page,
'previous_page': previous_page,
'top_article_list': top_article_list
})
<h2>最新文章h2>
{% for article in top_article_list %}
<h4><a href="/blog/detail/{
{ article.article_id }}">{
{ article.title }}a>h4>
{% endfor %}
全部结束啦，恭喜各位完成了一个Django项目。继续努力学习吧。还有很多很多可以优化的东西。
