SAE python django 同步数据库到线上

 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()

就可以建立对应的四个MSQ表格,这种做法本地操作没问题,可以DJANGO项目部署到SAE上面如何实现呢?

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
