如何使用 {{#each}} 在 Meteor 中显示许多嵌套对象？

Question

使用下面的 MongoDB 子文档，我如何使用 {{#each}} 块助手（或任何方法）来迭代 recurring 内的对象？

"recurring": {
    "T12345" : {
        "amount" : 102,
        "created_at" : "2014-09-29T17:43:18.414627+00:00",
        "status": "pending",
        "guid" : "T12345"
    },
    "T12346" : {
        "amount" : 102,
        "created_at" : "2014-09-30T17:45:02.768939+00:00",
        "status": "succeeded",
        "guid" : "T12346",

    }
}

JS 文件

Template.subscription.helpers({
subscription: function () {
    return this.recurring.transactions; //The subscription filters out the records marked viewable: false
},
    fname: function() {
        return this.customer.fname;
    },
    lname: function() {
        return this.customer.lname;
    },
    amount: function() {
        return this.debit.amount / 100;
    },
    trans_guid: function(key) {
        return this.recurring.transactions.key; //not sure how I can get the guid since the object that holds this property is named using the same guid
    }
});

HTML 文件

<table class="table bootstrap-datatable datatable small-font">
<thead>
    <tr>
        <th>Status</th>
        <th>Date</th>
        <th>Fund</th>
        <th>Amount</th>
        <th>Number</th>
    </tr>
</thead>   
<tbody>
    {{#each subscription}}
        <tr>
            <td><span class="label label-success">{{status}}</span></td>
            <td>{{trans_date}}</td>
            <td>{{fund}}</td>
            <td>{{amount}}</td>
            <td><b>{{trans_guid}}</b></td>
        </tr>                       
    {{/each}}                                                                               
</tbody>
</table>

我要做的是显示这一订阅的所有交易。可能只有一个，也可能有数百个。现在 Meteor 正在订阅整个文档，那么我如何告诉 Meteor 在哪里查找以列出每笔交易？

Template.registerHelper('addKeys', function (all) {

        return {key: k, value: i};
    });
});

JS：

Template.registerHelper('addKeys', function (all) {
    return _.map(all, function(i, k) {
        return {key: k, value: i};
    });
});

HTML：

<tbody>
    {{#each addKeys subscription}}
      {{#with value}}
        <tr>
            <td><span class="label label-success">{{status}}</span></td>
            <td>{{trans_date}}</td>
            <td>{{fund}}</td>
            <td>{{amount}}</td>
            <td><b>{{trans_guid}}</b></td>
        </tr>
      {{/with}}                 
    {{/each}}
