我想评估链接到两个不同用户的值。我创建了一个不同的表来跟踪用户以前的体验和他们感兴趣的体验，并将它们与用户联系起来。我有一个匹配函数试图找到最相似的用户，但它给出了标题中列出的属性错误。

模型：

class User(UserMixin, db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(64), index=True, unique=True)
    prev = db.relationship('prevExp', backref='user', lazy='dynamic')
    interested = db.relationship('interestedExp', backref='user',

    matches = db.relationship('Match', backref='matchedTo', lazy='dynamic')

class prevExp(db.Model):

    arts = db.Column(db.String(1))
    consulting = db.Column(db.String(1))
    dataScience = db.Column(db.String(1))
    education = db.Column(db.String(1))
    engineering = db.Column(db.String(1))
    finance = db.Column(db.String(1))
    government = db.Column(db.String(1))
    law = db.Column(db.String(1))
    management = db.Column(db.String(1))
    marketing = db.Column(db.String(1))
    medical = db.Column(db.String(1))
    technology = db.Column(db.String(1))
    expDescription = db.Column(db.String(400))
    userID = db.Column(db.Integer, db.ForeignKey('user.id'))

class interestedExp(db.Model): …
