評論列表顯示及排序,我的中心顯示

一、顯示全部評論
{% for foo in ques.comments %}html

{% 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">評論時間:{{ foo.creat_time }}</span>
                        <p>{{ foo.detail }}</p>
                    </li>
                </ul>

            {% endfor %}

 

二、全部評論排序
uquestion = db.relationship('Question', backref=db.backref('comments', order_by=creat_time.desc))前端

question = db.relationship('Question',backref = db.backref('comments',order_by=creat_time.desc))

 

三、顯示評論條數
{{ ques.comments|length }}python

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

  

 

四、完成我的中心app

1.我的中心的頁面佈局(html文件及相應的樣式文件)函數

 

2.定義視圖函數def usercenter(user_id):佈局

3.向前端頁面傳遞參數url

4.頁面顯示相應數據spa

發佈的所有問答code

發佈的所有評論htm

            </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)

  

五、各個頁面連接到我的中心

<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 }}評論:({{ foo.comments|length}})</a>

</div>
