Django之环境搭建

安装django

pip install django

 安装完django之后就有了可用的管理工具django-admin.py,我们可以用它来创建我们的项目。

django-admin的语法：

django-admin

Type 'django-admin help <subcommand>' for help on a specific subcommand.

Available subcommands:

[django]
    check
    compilemessages
    createcachetable
    dbshell
    diffsettings
    dumpdata
    flush
    inspectdb
    loaddata
    makemessages
    makemigrations
    migrate
    runserver
    sendtestemail
    shell
    showmigrations
    sqlflush
    sqlmigrate
    sqlsequencereset
    squashmigrations
    startapp
    startproject
    test
    testserver
Note that only Django core commands are listed as settings are not properly configured (error: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the env
ironment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.).

 启动项目

>python manage.py runserver 127.0.0.1:8001
Performing system checks...

Starting development server at http://127.0.0.1:8001/
Quit the server with CTRL-BREAK.

 

页面访问项目

 输入http://127.0.0.1:8001

项目已经运行成功了。。。。

但是提示你还没有创建一个app并且设置urls，那么我们按照它的提示来操作吧。

创建我们的app

>python manage.py startapp sqlOper

设置settings

DEBUG = False
ALLOWED_HOSTS = ['127.0.0.1']

设置views

from django.http import HttpResponse

def hello(request):
    return HttpResponse("hello Word ...")

设置urls

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^index', views.hello),
]

再次刷新一次
