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">
        {% for foo in ques.comments %}
            <li class="list-group-item">
                <span class="glyphion-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 class="comdetail">{{ foo.detail }}</p>

            </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=creat_time.desc))

     

  3. 显示评论条数
    {{ ques.comments|length }}
    <h4>评论：({{ ques.comments|length }})</h4>

@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.question,
        'comments':user.comments
    }
    return render_template('usercenter.html',**context)
