Answer 1

Your indentation is wrong. Instead of defining methods on User, you've defined module-level functions.

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)

Answer 2

You need to have your model class inherit from UserMixin

from flask_login import UserMixin

class User(db.Model, UserMixin):
   __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)
