Django管理员界面

启动管理界面

管理界面依赖于 django.contrib 模块。若需它工作，需要确保一些模块是否导入在 myproject/settings.py 文件中的INSTALLED_APPS和MIDDLEWARE_CLASSES元组。

INSTALLED_APPS = (
   'django.contrib.admin',
   'django.contrib.auth',
   'django.contrib.contenttypes',
   'django.contrib.sessions',
   'django.contrib.messages',
   'django.contrib.staticfiles',
   'myapp',
)

对于 MIDDLEWARE_CLASSES 有?

MIDDLEWARE_CLASSES = (
   'django.contrib.sessions.middleware.SessionMiddleware',
   'django.middleware.common.CommonMiddleware',
   'django.middleware.csrf.CsrfViewMiddleware',
   'django.contrib.auth.middleware.AuthenticationMiddleware',
   'django.contrib.messages.middleware.MessageMiddleware',
   'django.middleware.clickjacking.XFrameOptionsMiddleware',
)

c:\myproject> python manage.py syncdb 

syncdb将创建必要的表，或根据您的数据库类型的集合，以及必要的管理界面来运行。 即使你不是一个超级用户，系统会提示创建一个。

如果你已经有一个超级用户或忘记了，可以用下面的代码来直接创建一个 ?

c:\myproject> python manage.py createsuperuser 

现在就开始启动管理界面，我们需要确保已经为管理界面配置URL。打开 myproject/url.py，应该有这样的东西 ?

"""myproject URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/1.9/topics/http/urls/ 
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  url(r'^$', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.conf.urls import url, include
    2. Add a URL to urlpatterns:  url(r'^blog/', include('blog.urls'))
"""
from django.conf.urls import url
from django.contrib import admin
urlpatterns = [
    url(r'^admin/', admin.site.urls),
]

# 创建必要的数据库表，并初始化相关数据
C:\myproject>python manage.py migrate

C:\myproject>python manage.py createsuperuser
Username (leave blank to use 'administrator'): admin
Email address: admin@zyiz.net

c:\myproject> python manage.py runserver 

管理界面如下URL，应该是可以访问：http://127.0.0.1:8000/admin/

使用超级用户帐号登陆，会看到如下界面 ?

这个界面可以让我们管理 Django 中的组和用户，以及所有在应用程序中注册的模型。这个界面使您能够至少做到“CRUD”(创建，读取，更新，删除)模型操作。
