实现分页功能

教程：https://github.com/jamespacileo/django-pure-pagination views.py中的使用分页功能代码

class OrglistView(View): def get(self, request): all_orgs = CourseOrg.objects.all() org_nums = all_orgs.count() all_citys = CityDict.objects.all() try: page = request.GET.get('page', 1) except PageNotAnInteger: page = 1 p = Paginator(all_orgs, 2, request=request) orgs = p.page(page) return render(request, 'org_list.html', {'all_orgs': orgs, 'all_citys': all_citys, 'org_nums': org_nums})

1.注册：

pip install django-pure-pagination setting.py加入：

INSTALLED_APPS = ( ... 'pure_pagination', )

附： 可在setting.py加入以下代码来更改设置，不加入默认使用默认设置

PAGINATION_SETTINGS = { 'PAGE_RANGE_DISPLAYED': 10, 'MARGIN_PAGES_DISPLAYED': 2, 'SHOW_FIRST_PAGE_WHEN_INVALID': True, }

2.按照教程将代码具体修改 views.py

from pure_pagination import Paginator, EmptyPage, PageNotAnInteger try: page = request.GET.get('page', 1) except PageNotAnInteger: page = 1 p = Paginator(all_orgs, 5, request=request) orgs = p.page(page)

在return render 中all_orgs 改为 ‘all_orgs’: orgs, 注意，Paginator第二个参数为每页的显示个数，必须设置。

3.模板html

org_list.html中加入object_list

{% for course_org in all_orgs.object_list %}

在页码显示处将教程代码复制，并做细微修改

{% if all_orgs.has_previous %} <li class="long"><a href="?{{ all_orgs.previous_page_number.querystring }}">上一页</a></li> {% endif %} {% for page in all_orgs.pages %} {% if page %} {% ifequal page all_orgs.number %} <li class="active"><a href="?{{ page.querystring }}">{{ page }}</a></li> {% else %} <li><a href="?{{ page.querystring }}" class="page">{{ page }}</a></li> {% endifequal %} {% else %} <li class="none"><a href="">...</a></li> {% endif %} {% endfor %} {% if all_orgs.has_next %} <li class="long"><a href="?{{ all_orgs.next_page_number.querystring }}">下一页</a></li> {% endif %}
