##filter比filter_by查询麻烦,filter需带入类名，加==条件
    row =session.query(User).filter(User.username=='nanian').all()

    print(row[0].locked)
#还可以直接在user_modules写好查询函数

    session.commit()
def delete_user():
    row=session.query(User).filter_by(username='haha')[0]
    session.delete(row)
    session.commit()
if __name__=='__main__':
    #add_user()
    #search_user()
#调用module写好的查询条件查询
    #print(User.by_name('nanian'))
