您可以创建一个自定义路由器来执行此操作:
例子:
def get_current_site():
SITE_ID = getattr(settings, 'SITE_ID', 1)
site_name = Site.objects.get(id=SITE_ID)
return site_name
DATABASE_ROUTERS = ['CustomDatabaseRouter',] #a setting that Django understands.
class CustomDatabaseRouter(object):
def db_for_read(self, model, **hints):
site_name = get_current_site()
if site_name in ['site1']:
return 'db1'
if site_name in ['site2']:
return 'db2'
return 'default'
def db_for_write(self, model, **hints):
site_name = get_current_site()
if site_name in ['site1']:
return 'db1'
if site_name in ['site2']:
return 'db2'
return 'default'
def allow_syncdb(self, model, **hints):
site_name = get_current_site()
if site_name in ['site1'] and db == 'db1':
return True
if site_name in ['site2'] and db == 'db2':
return True
return False
