Django为管理活动提供随时可以使用的用户界面。 我们都知道,管理界面对于一个Web项目是十分重要的。 Django根据您的项目模型自动生成管理界面。
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。
对于 INSTALLED_APPS 确保有 -
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', )
在启动服务器,我们来访问管理界面,可能还需要启动数据库 -
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), ]
整个执行命令过程:
# 创建必要的数据库表,并初始化相关数据 C:\myproject>python manage.py migrate Operations to perform: Apply all migrations: admin, contenttypes, auth, sessions Running migrations: Rendering model states... DONE Applying contenttypes.0001_initial... OK Applying auth.0001_initial... OK Applying admin.0001_initial... OK Applying admin.0002_logentry_remove_auto_add...

It must contain at least 8 characters. This password is too common. This password is entirely numeric. Password: Password (again): Superuser created successfully. C:\myproject>
现在,只需使用下面的命令运行启动服务器。
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。
