Django分页功能的实现
方法/步骤
1、打开命令行窗口，创建Django工程，使用以下命令：django-adminstartprojectdjpagecddjpagepythonmanage.pystartappdemo
2、使用PyCharm打开工程，在工程的同名文件夹的settings.py文件，注册应用，添加模板路悄钸碌灵径，修改部分的settings.py内容如霍丶魇汜下：INSTALLED_APPS=['django.contrib.admin','django.contrib.auth','django.contrib.contenttypes','django.contrib.sessions','django.contrib.messages','django.contrib.staticfiles','demo.apps.DemoConfig']TEMPLATES=[{'BACKEND':'django.template.backends.django.DjangoTemplates','DIRS':[os.path.join(BASE_DIR,'templates')],'APP_DIRS':True,'OPTIONS':{'context_processors':['django.template.context_processors.debug','django.template.context_processors.request','django.contrib.auth.context_processors.auth','django.contrib.messages.context_processors.messages',],},},]
3、在工程同名文件的urls.py文件，添加到应用的视图的路由fromdjango.conf.urlsimporturlfromdjango.contribimportadminfromdemoimportviewsurlpatterns=[url(r'^admin/',admin.site.urls),url(r'page/(?P<id>\d+)/$',views.page)]
4、在应用的视图views.py文件，编写处理请求函数，实现分页显示一个列表的内容，这里列表也可以是查询集fromdjango.shortcutsimportrenderfromdjango.core.paginatorimportPaginator#Createyourviewshere.defpage(request,id):hello_list=[{'title':'hello'},{'title':'world'},{'title':'hello1'},{'title':'world1'},{'title':'hello2'},{'title':'world2'},{'title':'hello3'},{'title':'world3'},{'title':'hello4'},{'title':'world4'}]pag=Paginator(hello_list,2)page=pag.page(int(id))returnrender(request,template_name='home.html',context={'page':page})
5、在工程根目录新建templates文件夹，并创建一个home.html文件，代码如蛴蛩钔淞下：<!DOCTYPEhtml媪青怍牙><htmllang="en"><head><metacharset="UTF-8"><title>Title</title></head><body><ul>{%foriteminpage%}<li>{{item.title}}</li>{%endfor%}</ul>{%ifpage.has_previous%}<ahref="/page/{{page.previous_page_number}}"><上一页</a>{%endif%}{#遍历显示页码的链接#}{%forindexinpage.paginator.page_range%}{#判断是否是当前页#}{%ifindex==page.number%}{{index}}{%else%}<ahref="/page/{{index}}">{{index}}</a>{%endif%}{%endfor%}{#判断是否有下一页#}{%ifpage.has_next%}<ahref="/page/{{page.next_page_number}}">下一页></a>{%endif%}</body></html><!DOCTYPEhtml><htmllang="en"><head><metacharset="UTF-8"><title>Title</title></head><body><ul>{%foriteminpage%}<li>{{item.title}}</li>{%endfor%}</ul>{%ifpage.has_previous%}<ahref="/page/{{page.previous_page_number}}"><上一页</a>{%endif%}{#遍历显示页码的链接#}{%forindexinpage.paginator.page_range%}{#判断是否是当前页#}{%ifindex==page.number%}{{index}}{%else%}<ahref="/page/{{index}}">{{index}}</a>{%endif%}{%endfor%}{#判断是否有下一页#}{%ifpage.has_next%}<ahref="/page/{{page.next_page_number}}">下一页></a>{%endif%}</body></html>page.paginator.page_range是页面总数
6、运行django服务器pythonmanage.pyrunserver
7、打开网页，输入http://127.0.0.1:8000/page/1显示效果图如下，分页成功
