你的縮進是錯誤的。您定義了模塊級功能，而不是在User上定義方法。

class User(db.Model): 
    __tablename__ = "Contacts" 
    id = db.Column(db.Integer, primary_key = True) 
    name = db.Column(db.String(50)) 
    email = db.Column(db.String(50)) 
    age = db.Column(db.Integer) 

    def __init__(self, name, email, age): 
     self.name = name 
     self.email = email 
     self.age = age 

    def is_authenticated(self): 
     return True 

    def is_active(self): 
     return True 

    def is_anonymous(self): 
     return False 

    def get_id(self): 
     return unicode(self.id) 

    def __repr__(self): 
     return '<User %r>' %(self.name)
