我來推薦一個(gè)orm 庫,?tortoise-orm

這個(gè)支持異步操作 sqlite3、mysql、postgresql 三種數(shù)據(jù)庫, 配置和部署都比 sqlalchemy 簡單

你說的這個(gè)問題,?tortoise-orm 里面可以在初始化數(shù)據(jù)庫的時(shí)候

async?def?run():

????await?Tortoise.init(
????????"connections":?{
????????????'first_db':?{'engine':?'for',?'credential':?'bar'},
????????????'second_db':?{'engine':?'foze',?'credential':?'baze'}},
????????"apps":?{
????????????'app1':?{'models':?'__main__',?'default_connection':?'first_db'},
????????????'app2':?{'models':?'__main__';,?'default_connection':?'second_db'}
????)
????
connection1?=?Tortoise.get_connection('first_db')
connection2?=?Tortoise.get_connection('second_db')

?到這里, 后面的 `connection1` 等就可以用 orm 操作了
