after use generate_password_hash(password), password sequencethe is not in database

i am studying flask web, and have some question

@auth.route('/register', methods=['GET', 'POST'])
def register():
    form = RegistrationForm()
    if form.validate_on_submit():
        user=User(email=form.email.data,username=form.username.data, 
                  password_hash=form.password.data)
        db.session.add(user)
        db.session.commit()
        flash('you can now login')
        return redirect(url_for('auth.login'))
    return render_template('auth/register.html', form=form)


class User(UserMixin, db.Model): 
    __tablename__ = 'users'
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.Integer, unique=True, index=True)
    username = db.Column(db.String(64), unique=True, index=True)
    role_id = db.Column(db.Integer, db.ForeignKey('roles.id'))
    password_hash = db.Column(db.String(128))
    @property
    def password(self):
        raise AttributeError('password is not a readable attribute')

    @password.setter
    def password(self, password):
        self.password_hash = generate_password_hash(password)

    def verify_password(self, password):
        return check_password_hash(self.password_hash, password) 

    def __repr__(self):
        return '<user %r>' % self.username

database image

When I enter the account password registration, the password is 16. but The password of the database is also 16, not the sequence of the password.

i can't understand
