DateTime没有默认键作为输入。默认键应该是该
Column功能的输入。尝试这个：
import datetimefrom sqlalchemy import Column, Integer, DateTimefrom sqlalchemy.ext.declarative import declarative_basebase = declarative_base()class Test(base): __tablename__ = 'test' id = Column(Integer, primary_key=True) created_date = Column(DateTime, default=datetime.datetime.utcnow)
