AngularJS select box generated from object

I am refactoring some code, and want to change an array of code/name objects to be named objects. I want to do this so I can use it for equality tests. The old way was to compare the code directly...

if(current.addressCode === "1"){ ... }

But I would prefer to do it like this...

if(current.addressCode === types.student.address.letter.code){ ... }

The old object looks like this...

student{
  address: [
    {code: "0", name: "Select proof of address"},
    {code: "1", name: "Letter"},
    {code: "3", name: "Photograph"}
  ],
  id: [
    {code: "0", name: "Select type of ID"},
    {code: "1", name: "Passport"},
    {code: "2", name: "Driving Licence"}
  ]
}

So I want my new object to look like this...

student: {
  address: {
    select: {code: "0", name: "Select proof of address"},
    letter: {code: "1", name: "Letter"},
    photograph: {code: "3", name: "Photograph"},
  },
  id: {
    select: {code: "0", name: "Select type of ID"},
    passport: {code: "1", name: "Passport"},
    drivingLicense: {code: "2", name: "Driving Licence"},
  }
}

Where I am stuck, is I don't know how to generate a select element in angular js from this object which used to be generated from the old structure like this...

<select ng-model="current.addressCode" ng-options="t.code as t.name for t in student.address"></select>

How can I use the new object to generate a select form element?
