使用django-pure-pagination实现django的分页功能：
https://github.com/jamespacileo/django-pure-pagination

安装

pip install django-pure-pagination

添加到setting中：

INSTALLED_APPS = (
    ...
    'pure_pagination',
)

设置

在setting文件中添加代码：

PAGINATION_SETTINGS = {
    'PAGE_RANGE_DISPLAYED': 10,
    # 显示当前页面的相邻的页面数
    'MARGIN_PAGES_DISPLAYED': 2,
    # 显示的第一页和最后一页相邻的页数
    'SHOW_FIRST_PAGE_WHEN_INVALID': True,
    # 无效页面时，显示第一页而不是404页面
}

views中的代码：

from django.shortcuts import render
from django.views import View
from pure_pagination import Paginator, EmptyPage, PageNotAnInteger

from .models import Law


class LawlistView(View):
    def get(self, request):
        try:
            page = request.GET.get('page', 1)
        except PageNotAnInteger:
            page = 1
        objects = Law.objects.all()
        p = Paginator(objects, per_page=5, request=request)
        laws = p.page(page)

        return render(request, 'zcfg-list.html', {
            'laws': laws,
        })

templates中的代码：

<nav aria-label="Page navigation">
                  <ul class="pagination">
                  {% if laws.has_previous %}
                    <li>
                      <a href="?{{ laws.previous_page_number.querystring }}" aria-label="Previous">
                        <span aria-hidden="true">上一页</span>
                      </a>
                    </li>
                  {% else %}
                    <li class="disabled">
                      <a aria-label="Previous">
                        <span aria-hidden="true">上一页</span>
                      </a>
                    </li>
                  {% endif %}
                  {% for page in laws.pages %}
                      {% if page %}
                          {% ifequal page laws.number %}
                              <li class="active"><a href="?{{ page.querystring }}">{{ page }}</a></li>
                          {% else %}
                              <li><a href="?{{ page.querystring }}">{{ page }}</a></li>
                          {% endifequal %}
                      {% else %}
                          ...
                      {% endif %}
                  {% endfor %}
                  {% if laws.has_next %}
                    <li>
                      <a href="?{{ laws.next_page_number.querystring }}" aria-label="Next">
                        <span aria-hidden="true">下一页</span>
                      </a>
                    </li>
                  {% else %}
                    <li class="disabled">
                      <a aria-label="Next">
                        <span aria-hidden="true">下一页</span>
                      </a>
                    </li>
                  {% endif %}
                  </ul>
                </nav>
