        {% endblock %}

代码简单说明：

{% extends 'blog/base.html' %}  继承这个父模板

{% block 。。。。 %}  中间写入这个页面的展示内容，就是在填空  {% endblock %}

【视图设置blog/views.py】

rom django.shortcuts import render

# Create your views here.

def index(request):
    return render(request,'blog/index.html')

【分路由设置】

在blog新建一个py文件，名字取名：urls.py，你也也可以取一个其他的，但这个直观！，在里面输入：

from django.urls import path
from .views import index

urlpatterns = [
    path('', index,name='index'),#引号里是空白，说明是首页路由，name是取得别名！
]

【总路由设置：blog2019下的urls.py下设置】

from django.contrib import admin
from django.urls import path,include
from blog import urls
urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include(urls)),
    path('blog/', include(urls)),
