评论列表显示及排序，个人中心显示

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>')
   @log
   def usercenter(user_id):
       user=User.query.filter(User.id==user_id).first()
       context={
           'username':user.username,
           'questions':user.questions,
           'comments':user.comments
       }
       return render_template('usercenter.html',**context)

    

4. 完成个人中心

   <h4>评论：({{ ques.comments|length }})</h4><br>
           <ul class="list1">
               {% for foo in ques.comments %}
               <li class="list2">
                  <img style="width: 30px" src="{{ url_for('static',filename='../static/images/friends.jpg') }}" >
                   <a href="{{ url_for('all',user_id=foo.author_id) }}">{{ foo.author.username }}</a>
                   <span class="badge">{{ foo.creat_time }}</span><br>
                   <p class="pinglun">评论:{{ foo.detail }}</p><br>
               </li>
               {% endfor %}
       </ul>
