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 %}

{% for foo in ques.comments %}
               <li class="list-group-item" style="background-color:lightcyan;height:250px;width:600px;">
            <span class="glyphicon glyphicon-leaf" aria-hidden="true"></span>
            <a href="{{ url_for('usercenter',user_id=foo.author_id) }}">作者★{{ ques.author.username }}</a>
            <br>
            <a href="#">标题:{{ ques.title }}</a>
            <br>
            <p style="color:black">详情:{{ ques.detail }}</p>
            <p>评论:{{ foo.detail }}</p><br><br><br>
            <span class="badge"  style="margin-left: 60%">评论时间:{{ foo.create_time }}</span>
        </li>
     {% endfor %}

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=create_time.desc))

3.显示评论条数
{{ ques.comments|length }}

<h5>评论:({{ ques.comments|length }})</h5>

 

 

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
