Firebase如何获取单页数据

Question

我只是在项目中学习firebase和anfularfire。

    var myApp = angular.module('myApp', ['ngRoute','firebase']);

    myApp.config(function($routeProvider) {
        $routeProvider
        .when("/", {
            templateUrl: "home.html",
            controller: "TodoCtrl"
        })
        .when("/$id", {
            templateUrl: "single.html",
            controller: "SinglePage"
        })
    });

myApp.controller('TodoCtrl', function TodoCtrl($scope, $location, $firebase) {
    var fireRef = new Firebase('https://burning-heat-LINK.firebaseio.com/users');
    $scope.todos = $firebase(fireRef).$asArray();

    $scope.newTodo = '';


    $scope.addTodo = function() {
        var newTodo = $scope.newTodo;
        if (!newTodo.length) {
            return
        }
        $scope.todos.$add({
            title: newTodo
        })
        $scope.newTodo = ''
    };


    $scope.removeTodo = function(todo){
        $scope.todos.$remove(todo);
    };

    $scope.doneEditing = function(todo){
        var title = todo.title;
        if (title) {
            $scope.todos.$save(todo);
        } else {
            $scope.removeTodo(todo);
        }
    };

});

我有问题如何获取单个用户页面的数据。当我点击链接下面的链接时，我不会去数据只是单个用户的页面。

<a ng-href="/#/{{todo.$id}}">{{todo.$id}}</a>


myApp.controller('SinglePage', function SinglePage($scope, $location, $firebase) {
    var singlePageFirebase = new Firebase('https://burning-heat-LINK.firebaseio.com/').child('users');
    $scope.singlePage = $firebase(singlePageFirebase);
    console.log("singlePage", $scope.singlePage);
});
