我正在使用 AngularFire 创建一个简单的 Scrum 应用程序。基本上，用户可以注册，添加一些信息，然后在 Firebase 中创建一个用户。我正在使用 ng-repeat 在 team.html 页面上显示所有用户。

我目前有一个功能，允许用户单击“用户的磁贴”，它使用 ng-route 将您带到该特定用户的“dashboard.html”。我的dashboard.html 有一些更新用户的'color' 和'projectDescription' 属性的ng-change 指令——这些都与'DashboardController' 绑定。

如果“currentUuser”与dashboard.html 用户不同，我希望能够限制用户状态的更新。有人可以给我一个提示吗？

应用程序.js

var myApp = angular.module('myApp', 
['ngRoute', 'firebase', 'appControllers'])
.constant('FIREBASE_URL', 'https://scrumcheck.firebaseio.com/');

// Dependencies
var appControllers = angular.module('appControllers',['firebase']);

myApp.config(['$routeProvider', function($routeProvider){
$routeProvider.
    when('/login', {
        templateUrl: 'views/login.html',
        controller: 'RegistrationController'
    }).
    when('/team', {
        templateUrl: 'views/team.html',
        controller: 'MembersController'
    }).
    when('/views/dashboard/:uId/:mId', {
        templateUrl: 'views/dashboard.html',
        controller: 'DashboardController'
    }).
    when('/register', {
        templateUrl: 'views/register.html',
        controller: 'RegistrationController'
    }).
    otherwise({
        redirectTo: '/login'
    });
}]);

authentication.js（工厂）

myApp.factory('Authentication', function($firebase, 
  $firebaseSimpleLogin, FIREBASE_URL, $rootScope, $location) {

  var ref = new Firebase(FIREBASE_URL);
  var simpleLogin = $firebaseSimpleLogin(ref);

  var myObject = {

    login : function(user) {

      var userRef = new Firebase(FIREBASE_URL + '/users/' + user.uid);
      var userObj = $firebase(userRef).$asObject();

      userObj.$loaded().then(function() {
        $rootScope.currentUser = userObj;
      });

      return simpleLogin.$login('password', {
        email: user.email,
        password: user.password
      });
    }, //login

    register : function(user) {
      return simpleLogin.$createUser(user.email, user.password)
      .then(function(regUser){
        var ref = new Firebase(FIREBASE_URL + 'users');
        var firebaseUsers = $firebase(ref);

        var userInfo = {
          date: Firebase.ServerValue.TIMESTAMP,
          regUser: regUser.uid,
          firstname: user.firstname,
          email: user.email,
              image : "http://telehealth.org/wp-content/images/user-placeholder.jpg",
              color : "plain",
              projectDescription : "Currently working on...",
              yahoo : "yahooIM",
              upcoming : "PTO / WFH / OOO"
        }

        firebaseUsers.$set(regUser.uid, userInfo);
      }); //add user
    }, //register

    logout : function() {
      return simpleLogin.$logout();
    }, //logout

    signedIn: function() {
      return simpleLogin.user != null;
    }

    } //myObject

  //add the function to the rootScope

  $rootScope.signedIn = function() {
    return myObject.signedIn();
  }

  return myObject;
});

在dashboard.js 中：

var currentUser = $rootScope.currentUser;
$scope.isCurrentUser = function() {
  return currentUser.id == $scope.member.id;
};

然后在dashboard.html 中，您可以使用条件代码块：

<input ng-disabled="!isCurrentUser()">

<form ng-if="isCurrentUser()">

或类似的。
