Django 模板渲染

Step 0: 新建一个 Django 项目

django-admin startproject pyecharts_django_demo

创建一个应用程序

python manage.py startapp demo

在 pyecharts_django_demo/settings.py 中注册应用程序

# pyecharts_django_demo/settings.py
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'demo'  # <---
 ]

编辑 demo/urls.py文件

# demo/urls.py
from django.conf.urls import url

from . import views

urlpatterns = [
    url(r'^$', views.index, name='index'),
]

在 pyecharts_django_demo/urls.py 中新增 'demo.urls'

pyecharts_django_demo/urls.py
from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'demo/', include('demo.urls'))  # <---
]

Step 1: 拷贝 pyecharts 模板

先在 demo 文件夹下新建 templates 文件夹

将 pyecharts 模板，位于 pyecharts.render.templates 拷贝至刚新建的 templates 文件夹

chenjiandongx@DESKTOP-E83NUHA:/mnt/d/Python/pyecharts-django-demo/pyecharts_django_demo/demo/templates$ tree
.
├── jupyter_lab.html
├── jupyter_notebook.html
├── macro
├── nteract.html
├── simple_chart.html
├── simple_page.html
└── table.html

Step 2: 渲染图表

将下列代码保存到 demo/views.py 中。

from jinja2 import Environment, FileSystemLoader
from pyecharts.globals import CurrentConfig
from django.http import HttpResponse

CurrentConfig.GLOBAL_ENV = Environment(loader=FileSystemLoader("./demo/templates"))

from pyecharts import options as opts
from pyecharts.charts import Bar


def index(request):
    c = (
        Bar()
        .add_xaxis(["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"])
        .add_yaxis("商家A", [5, 20, 36, 10, 75, 90])
        .add_yaxis("商家B", [15, 25, 16, 55, 48, 8])
        .set_global_opts(title_opts=opts.TitleOpts(title="Bar-基本示例", subtitle="我是副标题"))
    )
    return HttpResponse(c.render_embed())

Step 3: 运行项目

python manage.py runserver

使用浏览器打开 http://127.0.0.1:8000/demo 即可访问服务

最后的项目文件
