《轻量级Django》笔记

一个最小的Django项目文件，包含 views，Url模式和配置即可。

文件 hello.py ：

import sys

from django.conf import settings
from django.conf.urls import url
from django.http import HttpResponse


# views
def index(request):
    return HttpResponse('Hello World')


# URL patterns
urlpatterns = (
    url(r'^$', index),
)


# settings
settings.configure(
    DEBUG=True,
    SECRET_KEY='SECRET_KEY_HERE',
    ROOT_URLCONF=__name__,
    MIDDLEWARE_CLASSES=(
        'django.middleware.common.CommonMiddleware',
        # 'django.middleware.csrf.CsrfViewMiddleware',
        # 'django.middleware.clickjacking.XFrameOptionsMiddleware',
    ),
)


if __name__ == '__main__':
    from django.core.management import execute_from_command_line
    execute_from_command_line(sys.argv)

测试运行

在命令行中启动：python hello.py runserver
运行的结果：
