django中怎么使用Highcharts.js实现可视化数据

新建project和app

django-admin startproject highcharts
cd highcharts
python manage.py startapp clusterbar

在clusterbar/models.py文件里添加代码

class PopulationByRegion(models.Model):
    region = models.CharField(max_length=50)
    pp1800 = models.IntegerField()
    pp1900 = models.IntegerField()
    pp2012 = models.IntegerField()

highcharts/urls.py文件代码

from django.contrib import admin
from django.urls import path
from django.urls import include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('clusterbar/',include('clusterbar.urls')),
]

在clusterbar文件夹下新建urls.py文件，写入代码

from django.urls import path
from . import views

urlpatterns = [
    path('popbyregion/',views.popbyregion,name="popbyregion"),
]

在clusterbar的views.py文件中写入代码

from django.shortcuts import render
from .models import PopulationByRegion

# Create your views here.

def popbyregion(request):
    df = PopulationByRegion.objects.all()
    region = []
    pp1800 = []
    pp1900 = []
    pp2012 = []
    for info in df:
        region.append(info.region)
        pp1800.append(info.pp1800)
        pp1900.append(info.pp1900)
        pp2012.append(info.pp2012)

    context = {'region':region,'pp1800':pp1800,'pp1900':pp1900,'pp2012':pp2012}
    return render(request,'popbyregion.html',context=context)

在highcharts文件夹下新建templates文件夹，在templates文件夹下新建popbyregion.html文件 并写入代码

注册app

添加模板路径

python manage.py makemigrations
python manage migrate

python manage.py shell
import csv
from clusterbar.models import PopulationByRegion

with open('example.csv') as csvfile:
    reader = csv.DictReader(csvfile)
    for row in reader:
        p = PopulationByRegion(region=rwo['continent'],
                               pp1800=int(row["year_1800"]),
                               pp1900=int(row['year_1900']),
                               pp2012=int(row['year_2012']))
        p.save()
quit()

python manage.py createsuperuser

依次输入用户名、邮箱密码 注册数据 在clusterbar文件夹下的admin.py中添加代码

from django.contrib import admin
from .models import PopulationByRegion
# Register your models here.

admin.site.register(PopulationByRegion)

启动服务器可以看到数据已经添加过来了

按照以上链接进行配置 后台变成了这样

输入链接http://127.0.0.1:8000/clusterbar/popbyregion/

可以看到结果

过程中我遇到了一个报错

django.core.exceptions.ImproperlyConfigured: The included URLconf '' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.
