问题描述
我想使用数据库路由器将模型中的特定表设置为特定的数据库。我发现的所有文档似乎解释了如何将特定应用程序路由到特定的数据库。
解决方案
看起来你可以使用
YMMV:没有测试过这个。
https://docs.djangoproject.com/en/dev/topics / db / multi-db /#using-router
class MyModel(models.Model):
_DATABASE =foo
class CustomRouter(object):
def db_for_read(self,model,** hints):
database = getattr(model,_DATABASE没有)
返回数据库
#重复db_for_write等
I have a Django (1.6) project with two databases. I have one app with one model, and multiple tables.
I want to use the database routers to set specific tables in the model to a specific database. All the documentation I have found seems to explain how to route a particular app to a particular database.
解决方案
Looks like you could use a custom router and model attribute for this.
YMMV: Haven't tested this.
https://docs.djangoproject.com/en/dev/topics/db/multi-db/#using-routers
class MyModel(models.Model):
_DATABASE = "foo"
class CustomRouter(object):
def db_for_read(self, model, **hints):
database = getattr(model, "_DATABASE", None)
return database
# repeat for db_for_write, etc.
