1. 显示所有评论
   {% for foo in ques.comments %}
   
   
2. 所有评论排序
   uquestion = db.relationship(‘Question‘, backref=db.backref(‘comments‘, order_by=creat_time.desc))
   
   
3. 显示评论条数
   {{ ques.comments|length }}

@app.route(‘/usercenter/<user_id>‘)

def usercenter(user_id):
    user = User.query.filter(User.id == user_id).first()
    context = {
        ‘username‘: user.username,
        ‘wenda‘: user.wenda,
        ‘comments‘: user.comment

    }
    return  render_template(‘usercenter.html‘,**context)
