多个角度选择标签

Question

我正在尝试使用相同的选项标记和值生成多个选择标记。它是一个用户表，将显示用户名，然后显示为他们选择的组，但我无法为每个用户选择正确的用户名而不是全部更改。

sh

var app = angular.module('todo',[]);

app.controller('option_list',function($scope){

  $scope.users = [
    {"id":0, "group_id":0, "name":"Caleb"},
    {"id":1, "group_id":2, "name":"Christie"},
    {"id":2, "group_id":0, "name":"Dawson"},
    {"id":3, "group_id":0, "name":"Kalen"}
  ]
  $scope.groups = [
    {"id":0, "name":"First Group"},
    {"id":1, "name":"Second Group"},
    {"id":2, "name":"Third Group"},
    {"id":3, "name":"Fourth Group"}
  ]
  for(var i = 0; i < $scope.users.length; i++){
    $scope.selected = {
      group: $scope.groups[$scope.users[i].group_id]
    }
  }

})
