Python的Django

1 第一部分目录详解

修改django的项目当中的url中的配置：

from django.contrib import admin
from django.conf.urls import url
from django.urls import path
from django.shortcuts import HttpResponse
def home(request):
    return HttpResponse('<h1>hello</h1>')
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^h.html/', home),
]

View Code

需要输入对应的页面才可以访问

#2 部分创建APP

建议做django的时候在比较干净的目录做，不要目录嵌套目录

创建app

D:\Document\Python0404\Django0425>python manage.py startapp cmdb

D:\Document\Python0404\Django0425>python manage.py startapp openstack

创建完后进行一定的修改，将之前放在根下的url文件中内容进行修改：

修改如下：D:\Document\Python0404\Django0425\Django0425\urls.py

from django.contrib import admin
from django.conf.urls import url
from django.urls import path
from cmdb import views
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^h.html/', views.home),
]

修改D:\Document\Python0404\Django0425\cmdb\views.py

from django.shortcuts import HttpResponse
def home(request):
    return HttpResponse('<h1>hello This is CMDB</h1>')
