Posted 2020-10-17 黄向薇

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

            <ul class="list-group">
             {% for foo in question %}
                  <li class="list-group-item">
                    <span class="glyphicon-leaf" aria-hidden="true"></span>
                  <img id="qu" src="{{ url_for(‘static‘,filename=‘images/title.png‘)}}">
                    <a href = "#">{{ foo.author.username }}{{ foo.title }}</a>
                           <span class="badge">{{ foo.create_time }}</span>
            </li>
                {% endfor %}
            </ul>

 

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

 

 ‘comments‘: Comment.query.order_by(‘create_time‘).all()

 

 

 

3.显示评论条数
{{ ques.comments|length }}

 

<span class="tcomment">评论：({{ ques.comments|length }})</span>

 

 

 

 

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

{% extends ‘index.html‘ %}
{% block title %}usercenter {% endblock%}
{% block main%}

<div class="page-header">
    <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span>
    {{username}} <br> <small>全部问答><span class="badge"></span> </small></h3>
    <ul class="list-group" style="">
