python学习笔记

if you want to change the server's IP,pass it along with the port.
So to listen on all public IPs,use:
python manage.py runserver 0.0.0.0:8000

urls.py
正则判断

import time
print time.strftime('%Y-%m-%d %H:%M:%S',time.localtime())

settings.py
TIME_ZONE = 'Asia/Shanghai'

setting.py
'ENGINE':'django.db.backends.mysql',
'NAME':'',
'USER':'',
'PASSWORD':'',
'HOST':'',
'PORT':'',

检查数据库配置
python manage.py shell
from django.db import connection
cursor = connection.cursor()

检查模型是否正确
python manage.py validate

提交SQL语句到数据库
python manage.py syncdb

model下所有
BlogPost.objects.all()

限制条件,只找出title='test'
BlogPost.objects.filter(title='test')

只找出单个数据
BlogPost.objects.get(title='test')
