Question

我已将此嵌套数据插入我的minimongo

db.orders.insert({ 
    _id: ObjectId().str,
    name: "admin",
    status: "online",catalog : [{
        "objectid" : ObjectId().str,
        "message" : "sold",
        "status" : "open"
    }]
});

我试图用这段代码显示它

<template name="Listed">
    <div class="row">
        {{#each list}}
            <article class="post">
                <a href="{{pathFor route='edit'}}"><h3>{{_id}}</h3></a>
                <a href="{{pathFor route='edit'}}"><h3>{{name}}</h3></a>
                <br>
                <a href="{{pathFor route='create'}}"><h3>{{status}}</h3></a>
                <br>
                {{#each ../catalog}}
                    <a href="{{pathFor route='create'}}"><h3></h3></a>
                    <a href="{{pathFor route='create'}}"><h3>{{status}}</h3></a>
                {{/each}}
                <div class="well"></div>
                <br/>    
            </article>
            <br/><br/>
        {{/each}}
    </div>
</template>

但未显示嵌套数据。如何显示嵌套数据？。

这是我的数据助手

/*****************************************************************************/
/* Listed: Helpers */
/*****************************************************************************/
Template.Listed.helpers({
    'list': function(){
        return Orders.find();
    }
});

您需要删除../

<template name="Listed">
    <div class="row">
        {{#each list}}
            <article class="post">
                <a href="{{pathFor route='edit'}}"><h3>{{_id}}</h3></a>
                <a href="{{pathFor route='edit'}}"><h3>{{name}}</h3></a>
                <br>
                <a href="{{pathFor route='create'}}"><h3>{{status}}</h3></a>
                <br>
                {{#each catalog  }}
                    <a href="{{pathFor route='create'}}"><h3></h3></a>
                    <a href="{{pathFor route='create'}}"><h3>{{status}}</h3></a>
                {{/each}}
                <div class="well"></div>
                <br/>    
            </article>
            <br/><br/>
        {{/each}}
    </div>
</template>

```

使用blaze显示嵌套数据
