How to filter JSON-Data with AngularJs?

I have an array (_users) that contains JSON objects.

{ 
  "User":
  {
    "userid":"19571",
    "status":"7",
    "active":"1",
    "lastlogin":"1339759025307",
    "Stats":
     [
       {
         "active":"1",
         "catid":"10918",
         "typeid":"71",
         "Credits":
         [
           {
             "content":"917,65",
             "active":"1",
             "type":"C7"
           },               
           {
             "content":"125,65",
             "active":"1",
             "type":"B2"
           }
         ]
       }
     ]
  }
}

1- How can I filter only users with "active":"1" not "0"

I have tried something like this:

<div ng-repeat="user in _users | filter:active | orderBy:user.userid">
    {{user.userid}}
</div>

but not working correctly for me.

Thank you!
