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 comment %}
                <ul style="padding-left: 0px;margin-bottom: 0px;">
                    <li style="width: 900px">
                        <a href="{{ url_for('usercenter',user_id = foo.author.id) }}">{{ foo.author.username }}</a>
                        <span class="badge">评论时间:{{ foo.creat_time }}</span>
                        <p>{{ foo.detail }}</p>
                    </li>
                </ul>

            {% 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=creat_time.desc))

 

3、显示评论条数
{{ ques.comments|length }}

<h4>评论：({{ quest.comments|length }})</h4>

　　

 

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

                        {% for foo in question %}
                            <li>
                                <a href="#">{{ foo.username }}</a>
                                <span class="badge">{{ foo.creat_time }}</span>
                                <p>{{ foo.detail }}</p>

                        {% endfor %}

                    <span class="badge"></span></small>
            </h3>
            {% for foo in comments %}
                <ul style="padding-left: 0px;margin-bottom: 0px;">
                <li style="width: 800px">
                    <a href="">{{ foo.author.username }}</a>
                    <span class="badge">{{ foo.creat_time }}</span>
                    <p>{{ foo.detail }}</p>
                </li>
            {% endfor %}
            </ul>
        </div>
        <div>
            <h3>{{ user }}<br>
                <small>个人信息</small>
            </h3>
            <ul style="padding-left: 0px;margin-bottom: 0px;">
                <li>用户：</li>
                <li>编号：</li>
                <li>昵称：</li>
            </ul>
        </div>
    </div>
{% endblock %}
</body>
</html>

　　

@app.route('/usercenter/<user_id>')
@loginFirst
def usercenter(user_id):
    user = User.query.filter(User.id == user_id).first()
    context = {
        'username':user.username,
        'question':user.question,
        'comments':user.comments
    }
    return render_template('usercenter.html',**context)

　　

5、各个页面链接到个人中心

<div class="meta">
    <a class="collection-tag" target="_blank" href="/c/1hjajt">{{ biaoqian }}</a>
    <a href="{{ url_for('usercenter',user_id = foo.author_id) }}">{{ foo.author.username }}评论：({{ foo.comments|length}})</a>

</div>
