Angular ng-options add selected depending on ajax data

Question

How would I force ng-options to use selected value depending on ajax result

this one hold selectable values used to loop

$scope.selectOptions = 
    {
        "api": "API",
        "json": "JSON",
        "xml": "XML",
        "csv": "CSV"
    };

feed holds returned ajax data and item.feed_type is the saved value which should be compared against $scope.selectOptions

<div ng-repeat="item in feed">
 <select ng-model="formInfo.feed_type" ng-options="k as v for (k,v) in selectOptions" class="form-control">
</div>

Answer 1

You can do it like this using ngInit to set formInfo.feed_type value to item.feed_type:

<div ng-repeat="item in feed" ng-init="formInfo.feed_type = item.feed_type">
    <select ng-model="formInfo.feed_type" ng-options="k as v for (k,v) in selectOptions" class="form-control"></select>
</div>
