def create_city(db: Session, city: schemas.CreateCity):
db_city = models.City(**city.dict())
print("*" * 50)
print("start")
print(db_city)
db.add(db_city)
print("add")
db.commit()
print("commit")
db.refresh(db_city)
print("refresh")
print(db_city)
print("end")
print("*" * 50)
return db_city经常会出现卡在commit不动的问题

可以贴一下 database.py, models - > City 类, schema -> CreatedCity 类, curd -> create_city 函数
这四个部分的代码, 感觉可能是哪个环节没有对上. 另外 sqlalchemy 版本是? 我这里比较新的 1.14 版本和教程里的一些操作不兼容
