參考以下鏈接設置django支持多數據庫時，遇到Django報錯：TypeError: allow_migrate() got an unexpected keyword argument 'model_name'

https://www.cnblogs.com/dreamer-fish/p/5469141.html

以下爲解決方案：

I meet the same problem when i move from 1.6.* to 1.10.Finally i found the problem cause by the DATABASE_ROUTERS

the old version i write like this

class OnlineRouter(object):
    # ... 
    def allow_migrate(self, db, model):
        if db == 'myonline':
            return model._meta.app_label == 'online'
        elif model._meta.app_label == 'online':
            return False
        return None

it work by rewrite like this

class OnlineRouter(object):
    # ... 
    def allow_migrate(self, db, app_label, model_name=None, **hints):
        if db == 'my_online':
            return app_label == 'online'
        elif app_label == 'online':
            return False
        return None
