• 新建视图cart

from models import CartInfo
from tt_user.user_decorators import user_login

@user_login
def cart(request):
    cart_list=CartInfo.objects.filter(user_id=request.session.get('uid'))
    context={'title':'购物车','cart_list':cart_list}
    return render(request,'tt_cart/cart.html',context)

• 模板代码如下

{% extends 'base.html' %}

{% block body %}
    <form method="post" action="/order/list/">
    {% csrf_token %}
    <div class="total_count">全部商品<em>2</em>件</div>

        <li class="col04">数量</li>
        <li class="col05">小计</li>
        <li class="col06">操作</li>
    </ul>
    {% for cart in cart_list %}
    <ul class="cart_list_td clearfix" id="{{ cart.id }}">
        <li class="col01"><input type="checkbox" checked="checked" name="cid" value="{{ cart.id }}"></li>

        <li class="col08"><a href="javascript:cart_del({{ cart.id }});">删除</a></li>
    </ul>
    {% endfor %}
