    post=db.relationship('PostModel',backref='highlight')

（2）cms/views.py

    post=PostModel.query.get(post_id)
    if not post:
        return restful.params_error(message='没有这篇帖子')
    highlight=HighLight()
    highlight.post=post
    db.session.add(highlight)
    db.session.commit()
    return restful.success()
