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.).

创建我们的项目

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
