Javascript django 500中的完整日历错误

我正在尝试在django应用程序中实现日历。我在另一篇文章中跟踪了这家伙的所作所为

当我转到app/cal时，我得到所有条目的json响应。我实现fullcalendar的页面出现500错误

GET http://127.0.0.1:8000/app/cal/?start=2015-08-30&end=2015-10-11&_=1442333348614 500 (INTERNAL SERVER ERROR)

这是我的密码：

models.py

class Entry(models.Model):

    start = models.DateField(blank=True, null=True)
    end = models.DateField(blank=True, null=True)

cal.html

<div id="calendar"></div>

    <script>
        $(document).ready(function(){
            $("#calendar").fullCalendar({
                events: "/app/cal/"
            })
        })
    </script>

$（文档）.ready（函数（）{
$（“#日历”）.fullCalendar({
事件：“/app/cal/”
})
})

它是

datetime.utcnow（）.replace（tzinfo=utc）

不是

datetime.now.replace（tzinfo=utc）

如果您处于调试模式，浏览器的开发工具应该向您显示来自ajax请求的回溯。如果你不能从中找出问题所在，请在这里发布。同意Alasdair的意见：错误500表示在运行Python代码时，没有捕获为Django异常（如404错误）的任何错误/异常。我认为这是ajax的问题。一旦我检查了python错误，就很容易排序了。谢谢
