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>
            <small>全部问答<span class="badge"></span></small>
        </h3>
        <ul class="list-group" style="margin: 10px">
            {% for foo in user.question %}
            <li class="list-group-item">

                <a href="#">{{ foo.author.username }}</a>
                <span class="badge">{{ foo.create_time }}</span>
                <p>{{ foo.detail }}</p>
            </li>
            {% endfor %}
        </ul>
    </div>

    <div class="page-header">

            </li>
            {% endfor %}
        </ul>
    </div>

    <div class="page-header">
        <h3><span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>{{ user.username }} <br>
            <small>个人信息<span class="badge"></span></small>

        <ul class="list-group" style="margin: 10px">
