AttributeError: 'NoneType' object has no attribute 'email'. Flask-sqlalchemy

Question

我有一个奇怪的问题...

我这样做：

  if request.method=="POST":

        email = request.form["email"]
        session["email"] = email

        found_user = users.query.filter_by(username=username).first()
        found_user.email = email
        db.session.commit()

给我这个问题：

        found_user.email = email
        AttributeError: 'NoneType' object has no attribute 'email'

谁能帮帮我？？ 谢谢 <3
