Flask-moment 无法通过moment.js 在网页上显示时间

[bestallen]

我想在主页上显示时间及显示是多少时间之前这2个功能
所以，通过flask-moment模板来进行设置，但是，却无法成功，下面是我的代码，麻烦帮忙看看是哪里出了错？？谢谢

这个是应用实例hello.py程序，已经使用了bootstrap

from flask.ext.bootstrap import Bootstrap
from flask.ext.moment import Moment
from flask import request
from datetime import datetime

app = Flask(__name__)
bootstrap=Bootstrap(app)
moment=Moment(app)

@app.route('/')
def index():
    return render_template('index.html',current_time=datetime.utcnow())

这个是templates下面的base.html文件


{% extends "bootstrap/base.html" %}
{%block head%}
{{super()}}
<link rel='shortcut icon' href="{{url_for('static',filename='favicon.ico')}}" type='image/x-icon'>
<link rel='icon' href="{{url_for('static',filename='favicon.ico')}}" type="image/x-icon">
{% block scripts %} #这里已经引入了moment.js库
{{ super() }} #但是不知道在这里引入是否算正确？？？
{{ moment.include_moment() }}
{% endblock %}*
{%endblock%}

{% block title %}Flasky{% endblock %}

{% block navbar %}
<div class="navbar navbar-inverse" role="navigation">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle"
data-toggle="collapse" data-target=".navbar-collapse">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="/">Flasky</a>
</div>
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav">
<li><a href="/">Home</a></li>
</ul>
</div>
</div>
</div>
{% endblock %}
{% block content %}
<div class="container">
{% block page_content %}{% endblock %}
</div>
{% endblock %}
[/code]

最后，这里是index.html里面的内容
<p>The local date and time is {{moment(current_time).format('LLL')}}.</p>
<p>That was {{moment(current_time).fromNow(refresh=True)}}</p>
