尝试使用jade json nested object个对象，但是each prod in order.productOrder并不是prod.name ...

JSON

在这里尝试了代码jade-demo，并且它是...... {/ p>

更新1

td.tdCenter= order.productOrder

给出：

[ { sku: 'APL', name: 'Apple', quantity: 2, price: 12, total: 24 }, { sku: 'AVC', name: 'Avocado', quantity: 2, price: 16, total: 32 } ]

td中的

。

mongodb的

"productOrder" : [ { "sku" : "APL" , "name" : "Apple" , "quantity" : 2 , "price" : 12 , "total" : 24} , { "sku" : "AVC" , "name" : "Avocado" , "quantity" : 2 , "price" : 16 , "total" : 32}]

控制台和mongodb的webStorm快照

订购包含无法显示的order.productOrder数据的屏幕截图我刚刚添加了一条td行：td.tdCenter= order.productOrder

更新2 - order.js控制器

exports.getOrders = (req, res) => {

    Order.find()
        .populate({
            path: 'orders',
            match: { _id: req.user._id }
        })
        .exec(function (err, orders) {
            orders.forEach(function(elem){
                console.log("ELEM = " + elem.productOrder);
                console.log("ELEM = " + typeof elem.productOrder);
            });

            res.render('account/orders', {
                title: 'ניהול ההזמנות שלי',
                angularApp: 'storeApp',
                orders: orders
            });
        });
};

order.js的控制台快照

console.log("ELEM = " + elem.productOrder);

我该如何解决这个问题？

Answer 1

首先，我必须感谢@robertklep的持久性和指导...
令人难以置信..... 3天_这个决议：

order.js控制器

Order.find().lean()
        .populate({

该查询需要lean() mongooose函数才能返回javascript objects可以在jade中解析的each＆{ for嵌套对象的循环，所以：

each order in orders
    tr
        td.tdRight= moment(order.paymentTrans.timestampSent).format('DD.MM.YYY')
        td.tdCenter.price= order.totalPerOrder
        td.tdLeft= order.paymentTrans.serviceName
        td.tdCenter
            button.btn.product.btn-primary(type='button', ng-click='showDetails()')
                | פירוט
    tr
        td.tdRight= 'name'
        td.tdCenter= 'price'
        td.tdCenter= 'quantity'
        td.tdLeft= 'total'
    for prod in order.productOrder
        tr
            td.tdRight= prod.name
            td.tdCenter= prod.price
            td.tdCenter= prod.quantity
            td.tdLeft= prod.total
