Display values of an array of object without using ng-repeat directive

Question

In MongoDB I have the following the document.

{
"_id": {
    "$oid": "58402903734d1d19c9a34cdd"
},
"deliveryComp": "abc",
"poorDel": 0,
"okDel": 1,
"wellDel": 0,
"veryWellDel": 1
}

When I call this data from mongodb using an angular controller it is being returned as an array, like so:

[{
"_id": {
    "$oid": "58402903734d1d19c9a34cdd"
},
"deliveryComp": "abc",
"poorDel": 0,
"okDel": 1,
"wellDel": 0,
"veryWellDel": 1
}]

I want to display the values but I don't want to use ng-repeat. Each value needs to be displayed in different parts of the app. There is no "repeating" data.

How can I achieve this?

do you know which entry you want to display at which position? — Fonzy

Extract each object into its own variable and then link that to the element on the site? (Hope I understood what you wanted) — Martin M

@Karthik the size of the array is 1. Exactly the same as shown in the question. It will always have only one object. I didn't save it as an array in the database. But its being returned as an array. — Skywalker

If you've only got 1 value in the array, you can use;

{{mongoDbData[0]._id.$oid}}

For every value in your array, use 0 because it's the first item in your array.

If not mistaken, the issue seems to be that the document object you were expecting in wrapped as the only element of an array. In your controller, do as follows:

// assuming document to be the array-wrapped response
$scope.documentData = document[0];

so that in your view you can use data binding on documentData

<span>{{ documentData._id.$oid }}</span>

This will remove the need to always fetch the first element of the array in your data binding expression.
