在django中为每个模型设置db [英] set db per model in django

问题描述

我一直在查看django的多db文档。我想把我的几个模型分解成不同的数据库。但我真的只是希望这些模型始终都在一个特定的数据库中。我不需要特殊路由。并且编写唯一的路由器只是说模型A，B和C住在数据库X中，模型D，E和F总是存在于数据库Y。

I've been looking over django's multi-db docs. I'd like to break a few of my models out into a different db. But I really just want those models to ALWAYS live in a particular db. I don't need special routing. And writing unique routers just to say "Models A, B, and C live in database X, models D, E, and F always live in database Y".

是有一个更简单的方法来设置这样的默认值？例如，作为模型元字段？

Is there a simpler way to set defaults like this? For instance, as a model meta field?

推荐答案

没有 Meta 这个字段（有一点在某一点，但由于其引入的限制而被删除）。您需要一个数据库路由器来控制哪些对象去什么数据库。在你的情况下，路由器应该很容易实现。

There is no Meta field for this (there was one at some point but it got removed because of the limitations it introduced). You need a database router to control which objects go to what database. In your case the router should be pretty easy to implement.
