  • 三十三、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 %}

    <ul class="list-group" style="margin: 10px">
            <a>{% for foo in ques.comments %}</a>
                <li class="list-group-item">
                <span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>
                    <a href="{{ url_for('usercenter',user_id=foo.author.id) }}">{{ foo.author.username }}</a>
                    <span class="badge">{{ foo.creat_time }}</span>
            <p style="">{{ foo.detail }}</p><br>
        </li>
        {% endfor %}
            </ul>

    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 }}

    <h4>评论:({{ ques.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、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

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

    html文件:

    {% extends 'base.html' %}
    {% block title %}个人中心{% endblock %}
    {% block main %}
    
        <div class="page-header">
            <h3><span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>{{ username }} <br>
