在JSON玉嵌套的對象將不顯示

試圖jade與nested object，但each prod in order.productOrder一個json對象並不一代產量prod.name ...在JSON玉嵌套的對象將不顯示

試過代碼在這裏jade-demo，它Worx的....

玉輸入

doctype html 
html(lang="en") 
    head 
    title= pageTitle 
    script(type='text/javascript'). 
     if (foo) { 
     bar(1 + 5)

UPDATE 1

td.tdCenter= order.productOrder

給出：

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

在 td

。

MongoDB的控制檯

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

webStorm快照和MongoDB

訂單截圖與uniteratable order.productOrder數據 我只是增加了一個td行，以便：td.tdCenter= order.productOrder

UPDATE 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

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

如何解決此的控制檯快照??

你表示JSON是被顯示在「UPDATE」從陣列不同。您的代碼實際上是否會因您發佈的JSON（「Banana」和「Fig」）而失敗？ – robertklep

@robertklep，我正在使用的只是不同的樣機數據...代碼失敗了，更多：'每個產品order.productOrder.length？ order.productOrder：['empty']'returns' empty' ... – Jadeye

我無法重現該問題，它對我來說工作得很好。查看[this gist]（https://gist.github.com/robertklep/b7bda8efc7249d44fd839c914a32165e）查看生成的輸出。 – robertklep

首先我必須感謝@robertklep持久化&指導...
難以置信..... 3 dayz ...對這一決議：

order.js控制器

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

查詢所需的lean() mongooose功能，以返回純javascript objects是jade在嵌套對象的each & for迴路可以解析，因此：

玉

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
