 8                             <span class="glyphicon glyphicon-left" aria-hidden="true"></span>
 9                             <a href="{{ url_for(‘comment‘,user_id=com.author.id) }}"
10                                target="_blank">{{ com.author.username }}</a>

15                     {% endfor %}
16                 </ul>

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

 1 <ul class="list-group" style="">
 2                     <h1>全部问题</h1>
 3                     {% for foo in questions %}
 4                         <li class="list-group-item" style="width: 800px">
 5                             <a class="wrap-img" href="#" target="_blank">
 6                                 <img src="http://www.bookmarkye.com/3.jpg" width="50px">
 7                             </a>
 8                             <span class="glyphicon glyphicon-left" aria-hidden="true"></span>
 9                             <a href="{{ url_for(‘comment‘,user_id=foo.author.id) }}"
10                                target="_blank">{{ foo.author.username }}</a>
11                             <br>
12                             <a href="{{ url_for(‘detail‘,question_id=foo.id) }}">{{ foo.title }}</a>
13                             <span class="badge">{{ foo.creat_time }}</span>
14                             <p style="">{{ foo.detail }}
15                             </p>
16                         </li>
17                     {% endfor %}
18                 </ul>

3.显示评论条数
{{ ques.comments|length }}

1 　　　　　　　　　<div class="list-group-item" style="margin-top: 30px;width: 800px;">
2                     <h1>名称：<small>{{ user.username }}</small></h1>
3                     <h1>问题数：<small>{{ questions|length }}</small></h1>
4                     <h1>评论数：<small>{{ comment|length }}</small></h1>
5                 </div>

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）

1 <link rel="stylesheet" href="http://cdn.static.runoob.com/libs/bootstrap/3.3.7/css/bootstrap.min.css">
2     <script src="http://cdn.static.runoob.com/libs/jquery/2.1.1/jquery.min.js"></script>
3     <script src="http://cdn.static.runoob.com/libs/bootstrap/3.3.7/js/bootstrap.min.js"></script>

　　2.定义视图函数def usercenter(user_id):

 1 # 某用户发布过的所有评论
 2 @app.route(‘/comment/<user_id>‘,methods=[‘GET‘,‘POST‘])
 3 def comment(user_id):
 4     user = User.query.filter(User.id == user_id).first()
 5     content = {
 6         ‘comment‘:user.comment,
 7         ‘questions‘:user.question,
 8         ‘user2‘:user
 9     }
10     return render_template(‘comment.html‘, **content)
