在django中为特定的数据库设置模型

I would like to ask how to set models to specific database . I'm still new to django and read about the Database Routing in the Django website, I have 2 models, userMod and adminMod.
userMod should go to database userDB.
adminMod should go to database adminDB.
But when I migrated it, both table exist in both database. I already have included app_label on meta, but its still not working. I am using django 1.8

我想问一下如何为特定的数据库设置模型。我还是django的新手，在django网站上了解了数据库路由，我有两个模型，userMod和adminMod。userMod应该访问数据库userDB。adminMod应该访问数据库adminDB。但是当我迁移它时，两个表都存在于两个数据库中。我已经在meta上包含了app_label，但是它仍然不能工作。我用的是django 1.8

EDIT: I am just trying it on userDB for a while and eventually will use it with adminDB. This is my code:

编辑:我只是在userDB上试用了一段时间，最终会在adminDB上使用它。这是我的代码:

routers.py

class router(object):

def db_for_read(self, model, **hints):
    if model._meta.app_label == 'userDB':
        return 'userDB'
    return None

def db_for_write(self, model, **hints):
    if model._meta.app_label == 'userDB':
        return 'userDB'
    return None

def allow_relation(self, obj1, obj2, **hints):
    if obj1._meta.app_label == 'userDB' or\
        obj2._meta.app_label == 'userDB':
            return True
        return None

def allow_migrate(self, db, app_label, model=None, **hints):
    if app_label == 'userDB':
        return db == 'userDB'
    return None

2 个解决方案

#1

Try this:

试试这个:

class userMod(models.Model):
   name = models.CharField(max_length=120)

   class Meta:
      db_table='userDB'

#2

Remember to tell django about your database router in the settings.py

记得在settings.py中告诉django关于数据库路由器的信息。

https://docs.djangoproject.com/en/1.8/topics/db/multi-db/

Search for DATABASE_ROUTERS setting

寻找DATABASE_ROUTERS设置
