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）

<div class="list-container">
    <div class="wenda">
        <h3>{#<span class="glyphicon glyphicon-leaf" aria-hidden="true"></span>#}{{ username1 }}<br><small>全部问答：</small></h3>
        <ul class="news-list">
                {% for foo in questions %}
                    <li style="padding-left: 0px; padding-right: 10px; box-shadow: rgba(0, 0, 0, 0.5) 0px 0px 0px 0px;">
                        <span class="glyphicon glyphicon-leaf" aria-hidden="true"></span>
                        <a href="#">{{ foo.author.username }}</a>
                        <span class="badgs">{{ foo.creat_time }}</span>
                        <br>
                        <a href=" #">{{ foo.title }}</a>
                        <p>{{ foo.detail}}</p>
                    </li>
                {% endfor %}
            </ul>
    </div>
    <div class="pinlun">
        <h3>{#<span class="glyphicon glyphicon-leaf" aria-hidden="true"></span>#}{{ username1 }}<br><small>全部评论：</small></h3>
        <ul class="news-list">
        {% for foo in comments %}
            <li style="padding-left: 0px; padding-right: 10px; box-shadow: rgba(0, 0, 0, 0.5) 0px 0px 0px 0px;">
                <span class="glyphicon glyphicon-leaf" aria-hidden="true" ></span>
                <a href="#">{{ foo.author.username }}</a>
                <br>
                <span class="badgs">{{ foo.creat_time }}</span>
                <p>{{ foo.detail}}</p>
            </li>
        {% endfor %}
    </ul>
    </div>

    <div class="per">
        <h3><span class="glyphicon glyphicon-leaf" aria-hidden="true"></span>{{ username1 }}<br><small>个人信息：</small></h3>
        <ul class="news-list">
            {#<li style="padding-left: 0px; padding-right: 10px; box-shadow: rgba(0, 0, 0, 0.5) 0px 0px 0px 0px;">#}
            <li class="list-group-item">用户：{{ username }}</li>
            <li class="list-group-item">编号：{{ user_id }}</li>
            <li class="list-group-item">昵称：</li>
            <li class="list-group-item">文章篇数：</li>

        </ul>
    </div>
</div>

 

2.定义视图函数def usercenter(user_id):

#用户中心
@app.route('/usercenter/<user_id>/')
@loginFirst
def usercenter(user_id):
    user = User.query.filter(User.id==user_id).first()
    context={
        'username1':user.username,
        'questions':user.question,
        'comments':user.comments
    }
    return render_template('usercenter.html',**context)

 

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
