Ember Handlebars Iterate object and display key inside nested each helper

问题

I want to iterate and render some text in my Ember Handlebars template

I have a JSON as below; (comes within item)

"reas":{"Display Text 1":[null],"Display Text 2":[null]}

I want to display the text (Display Text 1/Display Text 2) on UI i.e. keys of my object. So in my Ember Handlebars template, I do

{{#each item in item.reas}}
    <tr>
        <td>{{item}}</td>
    </tr>
{{/each}}

Earlier I had also tried the {{@key}

But I am unable to get the text. What am I doing wrong ?

PS: Please remember that this is Handlebars within Ember and this is nested each i.e. there is an outer each in the template.

Given following JSON (beautified version of one from your question):

{
    "reasons": {
        "Display Text 1": [
            null
        ],
        "Display Text 2": [
            null
        ]
    }
}

You could iterate on it using {{each-in}} helper:

{{#each-in item.reasons as |key value|}}
    <tr>
        <td>{{key}}</td>
    </tr>
{{/each-in}}
