1. 現(xiàn)在app的init中導入這兩個工具類，并且注冊到app中

   import os
   from flask import Flask,request
   from flask_sqlalchemy import SQLAlchemy
   from flask_wtf.csrf import CSRFProtect
   from werkzeug.utils import import_string
   from config import config
   from flask_moment import Moment
   from flask_bootstrap import Bootstrap
   moment = Moment()
   db = SQLAlchemy()
   csrf = CSRFProtect()
   bootstrap = Bootstrap()
   def create_app(config_name):
   
       # 參加Flask應用程序實例
       app = Flask(__name__)
       config_mode = config[config_name]
       app.config.from_object(config_mode)
       db.init_app(app)
       csrf.init_app(app)
       moment.init_app(app)
       bootstrap.init_app(app)
       filenames = os.listdir("app/resources")
       for filename in filenames:
           if os.path.isdir("app/resources/"+filename) and os.path.exists('app/resources/'+filename+'/__init__.py'):
               bp = import_string('app.resources.'+filename+':'+filename)
               app.register_blueprint(bp)
       return app,db
   

2. 在視圖函數(shù)中把要傳的參數(shù)傳給模板

   @user.route("/temp")
   def template():
       return render_template("user/index.html", current_time = datetime.utcnow())
   

3. 在模板中繼承bootstrap，加載moment模塊

{% extends "bootstrap/base.html" %}
{% block scripts %}
    {{ super() }}
    {{ moment.include_moment() }}
    {{ moment.lang('zh-CN') }}
{% endblock %}
{% block title %}flasky{% endblock %}
{% block content %}
{#<p>現(xiàn)在時間時: {{ moment().format('YYYY年M月D日, h:mm:ss a') }}.</p>#}
{#<p>已經過去了: {{ moment().fromTime(time) }}.</p>#}
{#<p>{{ moment().calendar() }}.</p>#}
    <p>The local date and time is {{ moment(current_time).format('LLL') }}.</p>
<p>That was {{ moment(current_time).fromNow(refresh=True) }}</p>
    <p>{{ current_time }}</p>
{% endblock %}
