从Firebase获取对象的好习惯？

Question

我有一个名为users的对象，用于存储每个name用户的个人资料信息（email和uid）。

我试图弄清楚当用户登录并在DOM中显示时检索此配置文件信息的方法。这样做的好习惯是什么？

这是我到目前为止所尝试的内容。虽然currentAuth已正确解析（因此authData.uid），但它不会在$scope.User中加载配置文件信息。

国

.config(function($stateProvider, $urlRouterProvider) {
  $stateProvider

  .state("home", {
      url: "/home",
      templateUrl: "templates/home.html",
      controller: "AppCtrl",
      resolve: {
        // controller will not be loaded until $waitForAuth resolves
        // Auth refers to our $firebaseAuth wrapper in the example above
        "currentAuth": ["Auth", function(Auth) {
          // $waitForAuth returns a promise so the resolve waits for it to complete
          return Auth.$waitForAuth();
        }]
      }
    })
  .state('app', {
    url: "/app",
    abstract: true,
    templateUrl: "templates/menu.html",
    controller: 'AppCtrl',
    resolve: {
        // controller will not be loaded until $requireAuth resolves
        // Auth refers to our $firebaseAuth wrapper in the example above
        "currentAuth": ["Auth", function(Auth) {
          // $requireAuth returns a promise so the resolve waits for it to complete
          // If the promise is rejected, it will throw a $stateChangeError (see above)
          return Auth.$requireAuth();
        }]
    }
  })
  .state('app.account', {
    url: "/account",
    views: {
      'menuContent': {
        templateUrl: "templates/account.html",
        controller: 'AccountCtrl'
      }
    }
  })

// other states

  $urlRouterProvider.otherwise('/app/playlists');
});

帐户Ctrl

.controller('AccountCtrl', function($scope, Users, currentAuth) {

      if(currentAuth) {
        $scope.User = Users.getUser(currentAuth.uid);
        $scope.authData = currentAuth;
      }
})

用户服务

.factory('Users', function() {
  var ref = new Firebase("https://<yourapp>.firebaseio.com/");
  return {
    getUser: function(userId){
        var refChild = ref.child("users").child(userId);
        var fnReturn = function(snap) {
          console.log(snap.val()) // works perfect!
          return snap.val();
        }
        return refChild.on('value', fnReturn)
    }
  }
})
