How to get object properties of a collection

help

Hi,

Snipped some code, but below should give idea what I’ve done.

Defined the seed data.

   var mylist = [{
         num: "ABC",
         items: [{  
            line: 1,
            item: "001"
         }, {
            line: 2,
            item: "002"
         }]
      }];

Created the template.

<template name="orders">      
  {{#each orders}}
     {{num}}
  {{/each}}
</template>

Created the helper.

Template.orders.helpers({
   orders ( ) {
      return orders.find({});
   }
});

Order numbers are being listed just fine. Now my problem, I want to show the items.

<template name="items">
  {{#each items}}
    {{item}}
  {{/each}}
</template>

Here’s the helper

Template.items.helpers ({
  items ( ) {

// my question below.

     }
});

how to return the items of the order?

TIA!

You would use the same Query to get the full collection, then cycle through each order, and then through the Items in the order.

{{#each orders}}
    {{num}}
    {{#each items}}
        {{item}}
    {{/each}}
{{/each}}

This is how I handle it with sub-documents that I iterate through.

ouch. that simple? :slight_smile:

thank you. i thought i tried that already, and it didn’t work. maybe some typo.

follow up question if i may, how do you find a record in the sub document?

So, you can do something like

Collection.find({ "order.item": <item number> })

I also find that the innerloop {{#each}} for sub-documents works better if I create the inside loop in it’s own template, then iterate over the template.
