我有一个从csv导入的现有sqlite db file . 我尝试使用sqlalchemy来自动化db文件 . 但它总是给我......
回溯（最近一次调用最后一次）：文件“", line 1, in File " C：\ Users \ Administrator \ AppData \ Local \ Programs \ Python \ Python36-32 \ lib \ site-packages \ sqlalchemy \ util_colle ctions.py”，第212行，在 getattr 加注AttributeError（key）AttributeError：destinationservices
任何帮助表示赞赏 .

Base = automap_base()
# engine, suppose it has two tables 'user' and 'address' set up
engine = create_engine("sqlite:///destServ.db")
# reflect the tables
Base.prepare(engine, reflect=True)
# mapped classes are now created with names by default
# matching that of the table name.
Service = Base.classes.destinationServices
