Question

所以......我正在尝试从flask app中提交一些sql，模型代码如下：

class User(UserMixin, db.Model):
    __tablename__ = '_users'

    id = db.Column(db.Integer, primary_key=True)
    user_email = db.Column(db.VARCHAR(50), nullable=False, unique=True)
    user_reg_date = db.Column(db.TIMESTAMP, nullable=False)
    last_login = db.Column(db.TIMESTAMP, nullable=True)
    passwd = db.Column(db.VARCHAR(80), nullable=True)
    social_id = db.Column(db.VARCHAR(80), nullable=True, unique=True)

    def __init__(self, user_email, passwd, social_id):
        self.user_email = user_email
        self.user_reg_date = current_time()
        self.passwd = passwd
        self.social_id = social_id


class Player(db.Model):
    __tablename__ = '_players'

    id = db.Column(db.Integer, primary_key=True)
    player_unique_id = db.Column(db.Integer, unique=True)
    user_id = db.Column(db.Integer, db.ForeignKey('_users.id'))
    affiliated_crew_id = db.Column(db.Integer, db.ForeignKey('crew.id'))
    player_nick = db.Column(db.VARCHAR(50), unique=True)
    player_highscore = db.Column(db.Integer)
    player_badge = db.Column(db.VARCHAR(100))
    player_rank = db.Column(db.Integer)

    def __init__(self, player_unique_id, user_id, affiliated_crew_id
                 , player_nick):
        self.player_unique_id = player_unique_id
        self.user_id = user_id
        self.affiliated_crew_id = affiliated_crew_id
        self.player_nick = player_nick
        self.player_highscore = 0
        self.player_badge = None
        self.player_rank = 0

我已经在SQL中有了正确的列（因为我从预制表中写了这些列），这一切都是正确的。

提交sql的部分如下：

player = Player(player_unique_id=00000, user_id=user_num, affiliated_crew_id=crew_id
                , player_nick=nick)
db.session.add(player)
db.session.commit()

它正在返回：

sqlalchemy.exc.InternalError：（pymysql.err.InternalError）（1054，“字段列表中的未知列'_users.id'”）[SQL：'INSERT INTO _players（player_unique_id，user_id，affiliated_crew_id，player_nick， player_highscore，player_badge，player_rank）VALUES（％（player_unique_id）s，_users.id，％（affiliated_crew_id）s，％（player_nick）s，％（player_highscore）s，％（player_badge）s，％（player_rank）s）'] [参数：{'player_unique_id'：84658，'affiliated_crew_id'：'1'，'player_nick'：'玩家'，'player_highscore'：0，'player_badge'：无，'player_rank'：0}]

我在这里做错了什么？到目前为止搜索没有帮助...

Answer 1

我使用原始的User类来获取User.id，它一直返回None。

由于User是我的flask-login用户类，因此我必须使用current_user.id来提取用户ID。

所以修复user_num初始化user_num = User.id user_num = current_user.id修复了所有内容...

谢谢所有调查问题的人......

flask sqlalchemy尽管有
