如何動態增加 database engine?

[SeedSeek]

database engine 沒在 settings.ini 裡面設定，想直接在 .py 的程式裡面加載新的 database engine 給 models 用，要如何做比較好?

[limodou]

下面这段代码是 uliweb.contrib.orm/__init__.py的初始化engine的代码，可以参考：

for name, d in settings.get_var('ORM/CONNECTIONS').items():
x = {'connection_string':d.get('CONNECTION', ''),
'debug_log':d.get('DEBUG_LOG', None),
'connection_args':d.get('CONNECTION_ARGS', {}),
'strategy':d.get('STRATEGY', 'threadlocal'),
'connection_type':d.get('CONNECTION_TYPE', 'long'),
'duplication':d.get('DUPLICATION', False),
}
orm.engine_manager.add(name, x)

主要就是通过 orm.engine_manager.add(name, options)
来添加一个新的engine，然后在Model上使用use(engine_name)来切换。
