AngularFire ng-repeat

I have a problem with angular + firebase.

I have 2 arrays

{
  "lessen" : {
    "-KlL8-2To1zQ6pVdKRe2" : {
      "codelink" : "",
      "demolink" : "",
      "publish" : 1,
      "tag" : "html",
      "tekst" : "",
      "titel" : "HTML - elementen",
      "user" : "8chFY1kE0iS2KjufzAauQ5m1IoS2"
    }
  },
  "users" : {
    "8chFY1kE0iS2KjufzAauQ5m1IoS2" : {
      "displayName" : "Jur Dekker"
    }
  }
}

What i want its a ng-repeat on the lessen, but that he show the displayName from de user.

like this

<table>
  <tr ng-repeat="lessen in lessen">
    <td>{{lessen.titel}}</td>
    <td>{{users.displayName (where lessen.user is equal to key from users) }}</td>
  </tr>
</table>

So actually I want him to take the displayName where user of lessen array is the same as the user in users.

You can get user using its key. Also the alias of ng-repeat current item should be different than original collection.

<table>
  <tr ng-repeat="l in lessen">
    <td>{{l.titel}}</td>
    <td>{{users[l.user].displayName || 'N/A'}}</td>
  </tr>
</table>
