from jinja2 import Environment,FileSystemLoader
####jinja2 专门去渲染前端页面的一种引擎  django 自带templates

from  django.http import HttpResponse
###渲染jinja2的一个类

from pyecharts.globals import CurrentConfig
###设置全局配置项

CurrentConfig.GLOBAL_ENV = Environment(loader=FileSystemLoader('templates'))
####配置html文件路径
####配置 django 直接渲染pyecharts中的html模板

from pyecharts import options as opts

from pyecharts.charts import Bar
####Bar 是柱状图
'''
实现网站交互逻辑
指定html文件进行渲染
'''
###视图

def hello(request):
    return HttpResponse('hello world')

#渲染数据

def pyechart_demo(request):
    '''
    :return:浏览器向网站后台发送的请求头

###render_embed 直接渲染到jiaja2里面
