学到9-9ORM这一课,参考教学代码写的

以下是我的代码

@web.route('/register', methods=['GET', 'POST'])
def register():
    form = RegisterForm(request.form)
    if request.method == 'POST' and form.validate():
        user = User()
        user.set_attrs(form.data)
        db.session.add(user)
        db.session.commit()
    return render_template('auth/register.html',form={'data':{}})
