python凤凰新闻数据分析（四）整合

python版本：3.5, bootstrap版本：3.3.7, django版本：2.0

通过win+r键进入cmd输入命令：

django-admin.py startproject website
cd website
python manage.py startapp tool

进入website/website/settings.py添加如下代码：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    'tool',#此处为添加
]
#最后一行添加如下代码
STATIC_URL = '/static/'

STATIC_ROOT = os.path.join(BASE_DIR, 'collectstatic')

STATICFILES_DIRS = (os.path.join(BASE_DIR, 'static'),)

在最外层website目录下创建static文件夹，进入static文件夹再创建bootstrap文件夹，相应教程可参考django引入bootstrap模板以及图片显示。

进入tool文件夹修改models.py，可参考python凤凰新闻数据分析（一）python爬虫数据爬取和python凤凰新闻数据分析（二）爬虫数据写入django sqlite3数据库

然后进入admin.py修改如下：

from django.contrib import admin

# Register your models here.
from .models import *

class InformationAdmin(admin.ModelAdmin):
    list_display = ('title','time','created')

admin.site.register(Information,InformationAdmin)

进入tool文件夹修改views.py，部分代码如下：

from django.shortcuts import render,render_to_response

# Create your views here.
from django.http import HttpResponse
from tool.models import *
from wordcloud import WordCloud
import matplotlib.pyplot as plt
import jieba

def plot(request):
    Information_news = Information.objects.all()
    Information_news_list = []
    I_num = M_num = S_num = E_num = F_num =0 #点击量总和,为之后饼状图数据
    slices = [] #为之后饼状图数据
    for each_I in Information_news:
        I_num += int(each_I.clicks)
        Information_news_list.append(str(each_I))
    slices.append(I_num)
    str_ = "".join(Information_news_list)
    Information_news_text = ' '.join(jieba.cut(str_))

    path = 'msyh.ttc'
    
    wordcloud = WordCloud(font_path=path).generate(Information_news_text)
    plt.imshow(wordcloud,interpolation='bilinear')
    plt.axis("off")
    plt.savefig("C:/pork/website/static/figure/Information.png")
    # 饼状图为点击量比例,需要单独到控制台生成,即python manage.py shell进入控制台,这里有个问题：生成的饼状图会覆盖词云 
    # activities = ['Information','Military','Sports','Entertainment','Finance']
    # cols = ['tan','cadetblue','y','palegreen','plum']
    # try:
    # plt.pie(slices,
    #         explode=[0,0.2,0,0,0],
    #         labels=activities,
    #         colors=cols,
    #         startangle=90,
    #         shadow=False,
    #         autopct='%1.1f%%')
    # except ValueError as e:
    #     pass
    # plt.savefig("C:/pork/website/static/figure/Total.png")
    
    return render(request,'news_plot.html')

在tool文件夹下新建templates文件夹，在tool/templates/创建news_plot.html，可参考django引入bootstrap模板以及图片显示

<!DOCTYPE html>
<html>
<head>
	<meta charset="utf-8"> 
	<title>新闻网站的数据分析</title>

修改website/website/urls.py如下：

from django.contrib import admin
from django.urls import path
from tool.views import *

urlpatterns = [
    path('index/',plot),
    path('admin/', admin.site.urls),
]

然后cmd输入：

python manage.py runserver 0.0.0.0:8000

浏览器输入127.0.0.1:8000/index即可看到：
