Angularjs can't select default value html select

I've got the following problem while editing an existing CD with angular js. I want the dropdown to be selected to the current id from the ReleaseStudio of the cd.

<select ng-model="cd.ReleaseStudio.id">
        <option ng-repeat="studio in studios" value="{{studio.id}}" >{{studio.name}}</option>
</select>

The code works. The option is bound to the cd.ReleaseStudio.id. But the current cd.ReleaseStudio.id isn't selected by default when I enter the edit screen. It sits on a blank line and I've to reselect the studio, even if I just want to edit the cd.name field.

I found multiple answers on stackoverflow saying it would go automatically, but none of them worked for me. Can somebody tell me what I'm doing wrong?

AngularJS - Set default value on select inside a ng-repeat Angular.js: Using ng-model for dropdowns within ng-repeat

Thanks in advance

<select ng-init="ModelValue = options[0]" ng-model="ModelValue" ng-options="option.name for option in options"></select>

You should try this way:

<select ng-model="cd.ReleaseStudio.id" ng-options="studio.id as studio.name for studio in studios"></select>

And if you want to have a preselected empty value:

<select ng-model="cd.ReleaseStudio.id" ng-options="studio.id as studio.name for studio in studios">
  <option value=""> --- Please select --- </option>
</select>
