1. 显示所有评论
   {% for foo in ques.comments %}
   

   <ul>
           <p style="font-weight: 600;font-size: 16.5px">Comment[{{ question.comments|length }}]</p>
           <div>
               {% for foo in question.comments %}
               <li>
                     <img src="{{ url_for('static',filename='image/xiaolian.png') }}">
                     <a href="{{ url_for('usercenter',user_id=foo.author_id) }}">{{ foo.author.username }}</a>
                     <span>{{ foo.creat_time }}</span><br>
                     <p>{{ foo.detail }}</p>
               </li>
               {% endfor %}
           </div>
       </ul>

    

2. 所有评论排序
   uquestion = db.relationship('Question', backref=db.backref('comments', order_by=creat_time.desc))
   

   question = db.relationship('Question', backref=db.backref('comments',order_by=creat_time.desc))

    

3. 显示评论条数
   {{ ques.comments|length }}
   

       <p style="font-weight: 600;font-size: 16.5px">Comment[{{ question.comments|length }}]</p>
