django 分页功能

一、安装django-prue-pagination

在pycharm中 File==》settings==》Project：项目名===》Project Interpreter==》点击“+”===》搜django-prue-pagination===》左下角Intall Package

二、在sttings.py中的相关代码：

.....

#注册pure_pagination
INSTALLED_APPS = [
    .......    
    'pure_pagination',
]

......
#追加pure_pagination配置代码
PAGINATION_SETTINGS={
    'PAGE_RANGE_DISPLAYED':10,
    'MARGIN_PAGES_DISPLAYED':2,
    'SHOW_FIRST_PAGE_WHEN_INVALID':True,
}

三、在views.py中添加分页代码：

......
from .models import ShopProfile
......
from pure_pagination import Paginator,EmptyPage,PageNotAnInteger

......

class ShopList(View):
    """商铺列表"""
    def get(self,request):
        shops=ShopProfile.objects.all()
        # 每页五个
        p = Paginator(shops, 5)
        page = request.GET.get('page', 1)
        try:
            shops= p.page(int(page))
        except PageNotAnInteger:
            shops=p.page(1)
        return render(request,'shops_list.html',{'all_shops':shops})

四、在shop-list.html中的代码：

......
<!--收到后台分页后 返回的数据，然后进行遍历-->
<div id="portfoliolist">

        {% for shop in all_shops.object_list %}   <!--关键代码，一定注意这里！要遍历的不是all_shops而是all_object_list，这里是一个巨坑！不然会报错：

'Page' object is not iterable-->

        <div class="portfolio shop" data-cat="shop">
            <div class="portfolio-wrapper">
                <img src="{% static 'logo/shop.jpg' %}" alt="" />
                <div class="label">
                    <div class="label-text"><a class="text-title">{{ shop.name }}</a><span class="text-category">{{ shop.shop_sn }}</span></div>
                    <div class="label-bg"></div>
                </div>
            </div>
        </div>
        {% endfor %}

    </div>



<!--分页的代码-->

    <div class="fen-page">
       <ul class="pagelist pagination">
        {% if all_shops.has_previous %}
            <li class="long">
                <a href="?{{ all_shops.previous_page_number.querystring }}" class="prev">上一页</a>
            </li>
        {% endif %}
        {% for page in all_shops.pages %}
            {% if page %}
                {% ifequal page all_shops.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_shops.has_next %}
            <li class="long">
                <a href="?{{ all_shops.next_page_number.querystring }}">下一页</a>
            </li>
        {% endif %}
        </ul>
    </div>
