django数据库建表不用写MYSQL语句,直接在models.py中定义好model类,然后执行 python manage.py syncdb 就可以直接自动创建对应的表了。如下代码所示
class Publisher(models.Model):
name = models.CharField(max_length = 30)
address = models.CharField(max_length = 50)
city = models.CharField(max_length = 60)
state_province = models.CharField(max_length = 60)
country = models.CharField(max_length = 50)
website = models.URLField()
class Author(models.Model):
first_name = models.CharField(max_length = 30)
last_name = models.CharField(max_length = 40)
email = models.EmailField()
class Book(models.Model):
title = models.CharField(max_length = 50)
authors = models.ManyToManyField(Author)
publisher = models.ForeignKey(Publisher)
publish_date = models.DateField()
1. 本地得安装 SAE 环境
2. settings.py 中加入以下代码
if True:
from sae._restful_mysql import monkey
monkey.patch()
MYSQL_HOST_M = 'w.rdc.sae.sina.com.cn'
MYSQL_PORT = '3307'
MYSQL_USER = 'APP_ACCESS'
MYSQL_PASS = 'APP_SECRET'
MYSQL_DB = 'app_APP_NAME'
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': MYSQL_DB,
'USER': MYSQL_USER,
'PASSWORD': MYSQL_PASS,
'HOST': MYSQL_HOST_M,
'PORT': MYSQL_PORT,
}
}
其中, APP_ACCESS, APP_SECRET, APP_NAME 都在sae的应用页可以看到,换成你应用的相关代码,然后执行 sync db 即可
执行完之后, True 改成 False
