Django 分页的实现

一、views.py

class ListView(View):
    """列表"""
    def get(self, request, type_id, page):
        """显示列表"""
        goods_list = GoodsSKU.objects.filter(type=type_id)
        paginator = Paginator(goods_list, 1)
        goods_list_page = paginator.page(page)

        num_pages = paginator.num_pages
        if num_pages < 5:
            pages = range(1, num_pages + 1)
        elif page <= 3:
            pages = range(1, 6)
        elif num_pages - page <= 2:
            pages = range(num_pages - 4, num_pages + 1)
        else:
            pages = range(page - 2, page + 3)

        content = {
            'goods_list_page': goods_list_page,
            'type_id': type_id,
            'pages': pages,
        }
        return render(request, 'list.html', content)

二、list.html

<div class="pagenation">
    {% if goods_list_page.has_previous %}
        <a href="{% url 'goods:list' type_id goods_list_page.previous_page_number  %}?sort={{ sort }}"><上一页</a>
    {% endif %}
    {% for page_index in pages %}
        {% if page_index == goods_list_page.number %}
            <a href="{% url 'goods:list' type_id page_index %}?sort={{ sort }}" class="active">{{ page_index }}</a>
        {% else %}
            <a href="{% url 'goods:list' type_id page_index %}?sort={{ sort }}" >{{ page_index }}</a>
        {% endif %}
    {% endfor %}
    {% if goods_list_page.has_next %}
        <a href="{% url 'goods:list' type_id goods_list_page.next_page_number  %}?sort={{ sort }}"><下一页</a>
    {% endif %}
</div>
