如何解决Flask restful/sqlalchemy 更新/setattr 多个字典同时
如何使用 Python 在 Flask framework 中同时更新/设置多个字典？
假设我有三张表PeopleSkill、SkillRecord和PeoplePecord（其实是11张不同的表，情况类似），每张表都有project_id和{{1 }}，我想改变人的skill_name，我只能改变表skill_name的，我不能改变PeopleSkill和PeoplePecord，有什么办法解决这个问题吗？一旦一列发生变化，其他表的相关列也会发生变化。现有数据库中没有外键，我别无选择?
SkillRecord以下是 Postman 上 update_project_args = reqparse.RequestParser()
update_project_args.add_argument("project_id",type=str,required=True,help="project_id")
update_project_args.add_argument("people_skill",type=dict,required=False,help='people_skill')
update_project_args.add_argument("skill_record",help='skill_record')
update_project_args.add_argument("people_record",help='people_record')
def put(self):
args = self.project.parse_args()
try:
project_id = args.get("project_id")
people_skill = args.get("people_skill")
skill_record = args.get("skill_record")
project_record = args.get("project_record")
d_skill = db.session.query(PeopleSkill).filter_by(project_id=project_id).first()
{setattr(d_skill,k,v) for k,v in skill.items()}
d_people_skill = db.session.query(PeopleRecord).filter_by(project_id=project_id).first()
{setattr(d_people_skill,v in people_skill.items()}
db.session.commit()
return {"status": True,"message": "Saved successfully","data": None}
except Exception as e:
db.session.rollback()
current_app.logger.error(e)
return {"status": False,"message": "Saved Failed","data": None}
