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 }}
   
   
4. 完成个人中心

1.个人中心的页面布局（html文件及相应的样式文件）

2.定义视图函数def usercenter(user_id):

3.向前端页面传递参数

4.页面显示相应数据

发布的全部问答

发布的全部评论

个人信息

5.各个页面链接到个人中心

 

<h4>评论：({{ quest.comment|length }})</h4>
     {% for foo in comments %}
