1 第一部分目錄詳解css

修改django的項目當中的url中的配置：html

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),
]

須要輸入對應的頁面才能夠訪問python

#2 部分建立APPjquery

建議作django的時候在比較乾淨的目錄作，不要目錄嵌套目錄django

建立appapp

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

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

建立完後進行必定的修改，將以前放在根下的url文件中內容進行修改：url

修改以下：D:\Document\Python0404\Django0425\Django0425\urls.pyspa

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>')

Class-based views

    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
