日期函數不作爲屬性

我想使用日期函數來聲明Ember中的屬性，但它不顯示。沒有錯誤，但沒有數據。我今天跑=新日期（）; & getFullYear（today）;在控制檯中，但它會回到「未知」狀態。我無法獲得這些函數來模擬我的數據。這是怎麼回事？日期函數不作爲屬性

<body> 
<script type="text/x-handlebars" data-template-name="application"> 
    <div id="navbar"> 
     <ul> 
     <li>{{#link-to "calendar"}}Calendar{{/link-to}}</li> 
     <li>{{#link-to "about"}}About{{/link-to}}</li> 
     </ul> 
    </div> 
    <div id="content"> {{outlet}} </div> 
    <footer id='container'>Footer information here!</footer> 

    </script> 
    <script type="text/x-handlebars" data-template-name="about"> 
    <h1>About</h1> 
    <p>My calendar Date picker!</> 
    </script> 
    <script type="text/x-handlebars" data-template-name="calendar"> 
    <h1>Calendar Page</h1> 
    <button>Next</button> 
    <button>Today</button> 
    <button>Back</button> 
    <hr> 

     {{today}} 

    <hr> 
    </script> 
</body> 

var App = Ember.Application.create({ 
    LOG_TRANSITIONS: true 
}); 

App.Router.map(function() { 
    this.resource('calendar'); 
    this.resource('about');   
}); 

App.IndexRoute = Ember.Route.extend({ 
    redirect: function(){ 
     this.transitionTo('calendar'); 
    } 
}); 

App.CalendarRoute = Ember.Route.extend({ 
    model: function(){ 
     return App.CalendarData; 
    }, 
    serializer: function(model){ 
     return {month: model.get('Today')}; 
    } 
}); 

// calendar controller 


// calendar data 
App.CalendarData = Ember.Object.extend({ 
    today: function(){ 
     var Today = new Date(); 
     return Today; 
    }.property(), 

    date: function(today){ 
     var Date = Today.getDate(); 
     return Date; 
    }.property(), 

    month: function(Today){ 
     // this array gives month names 
     var MonthA = new Array(); 
     MonthA[0] = "January"; 
     MonthA[1] = "February"; 
     MonthA[2] = "March"; 
     MonthA[3] = "April"; 
     MonthA[4] = "May"; 
     MonthA[5] = "June"; 
     MonthA[6] = "July"; 
     MonthA[7] = "August"; 
     MonthA[8] = "September"; 
     MonthA[9] = "October"; 
     MonthA[10] = "November"; 
     MonthA[11] = "December"; 
     var Month = Today.getMonth(); 
     return MonthA[Month]; 
    }.property('month'), 

    dow: function(Today){ 
     var Weekday = new Array(); 
     Weekday[0] = "Sunday"; 
     Weekday[1] = "Monday"; 
     Weekday[2] = "Tuesday"; 
     Weekday[3] = "Wednesday"; 
     Weekday[4] = "Thursday"; 
     Weekday[5] = "Friday"; 
     Weekday[6] = "Saturday"; 
     var dow = Today.getDay(); 
     return Weekday[dow]; 
    }.property(), 

    year: function(Today){ 
     var Year = Today.getFullYear(); 
     return Year; 
    }.property() 

});

我不知道你在哪裏得到了如何做一個計算的屬性的示例，但你可能想看看在計算性能的指南。

today: function(){ 
    var today = new Date(); 
    return today; 
}.property(), 

date: function(){ 
    var date = this.get('today').getDate(); // grab the computed property `today` 
    return date; 
}.property('today'), // this says, when today computed property changes, you should mark this property as dirty
