##install
##创建工程 1.生成
django-admin.py startproject chshtvp
cd chshtvp/
python manage.py startapp cms
2.settting.py，将demoapp加入到INSTALLED_APPS
# Application definition
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'cms',
)
3.修改settting.py，将默认的sqlite数据库换成mysql
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'chshtvp',
'USER': 'root',
'PASSWORD': '1234',
'HOST': '127.0.0.1',
'PORT': '3306',
}
}
4.在demoproject下输入：python manage.py dbshell，如果能正常进入mysql命令行，则说明连接成功 5.启动应用
-
同步数据库：执行python manage.pysyncdb，第一次启动需要创建superuser，用来管理django后台
You have installed Django's auth system, and don't have any superusers defined. Would you like to create one now? (yes/no): yes Username (leave blak to use 'gouxulei'): frank Email address: fengxuting@gmail.com Password: 2****8 Password (again): Superuser created successfully. -
启动服务：python manage.py runserver
##template 1. {% load staticfiles %} {% static "img/menu2_bg03.png" %}
2.{{{{STATIC_URL}}img/kv_01.jpg If {{ STATIC_URL }} isn’t working in your template, you’re probably not using RequestContext when rendering the template.
