Handlebars - Element Reference

Hi

How can I reference an element in an outer iteration if an element with the same name already exists in the inner iteration?

Here's a sample JSON payload:

The element I'm referring to in this example is the "id" element. It exists in the "data" array and in the "location" array.

{
    "data": [
        {
            "id": 35435,
            "company": {
                "name": "Test Company",
                "location": [
                    {
                        "id": 5185,
                        "value": "America"
                    },
                    {
                        "id": 5186,
                        "value": "USA"
                    }
                ]
            },
            "name": "John Doe"
        }
    ]
}

I'm using the file template, but "result.data.id" doesn't return any value:

data_id,location_id,value
{{#each result.data}}
{{#each company.location}}
{{result.data.id}},{{id}},{{value}}
{{/each}}
{{/each}}

I want the following output:

data_id,location_id,value
35435,5185,America
35435,5186,USA

Am I missing something or should this output be produced using a different approach?

    Hi Chad.

    You can use "../" notation to look back one level. Based on the JSON you provided, the following template produces the output you're looking for. See the template in action here.

    data_id,location_id,value
    {{#each data}}
    {{#each company.location}}
    {{../id}},{{id}},{{value}}
    {{/each}}
    {{/each}}
