{% for foo in ques.comments %}

<h3>评论区:
    ({{ ques.comments|length }})
</h3><br>


<div class="basic_box" style="padding-bottom: 50px;">
    <ul class="list-group" style="margin-bottom: 10px">
      {% for qu in ques.comments %}

            <li class="list-group-item" style="width: 800px">


                <a class="wrap-img" href="#" target="_blank">
                    <img src="{{ qu.author.image }}" width="50px">
                </a>
                <span class="glyphicon glyphicon-left" aria-hidden="true"></span>

                <br>
                <a href="{{ url_for(‘person‘,user_id=qu.author.id) }}">{{ qu.author.username }}</a>
                <span class="badge">评论时间:{{ qu.creat_time }}</span>
                <p style="">{{ qu.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))

class Comment(db.Model):
    __tablename__ = ‘comment‘
    id = db.Column(db.Integer, primary_key=True, autoincrement=True)
    author_id = db.Column(db.Integer, db.ForeignKey(‘user.id‘))
    sent_id = db.Column(db.Integer, db.ForeignKey(‘sent.id‘))
    creat_time = db.Column(db.DateTime, default=datetime.now)
    detail = db.Column(db.TEXT, nullable=False)
    sent = db.relationship(‘Sent‘, backref=db.backref(‘comments‘,order_by=creat_time.desc))
    author = db.relationship(‘User‘, backref=db.backref(‘comments‘))

3.显示评论条数

用户：

<div class="all have-img">

    <div>
        {% for foo in username %}
        <h4>用户名：{{ foo.author.username }}
            <br>
            <small>全部问答</small>
        </h4>
        <ul style="padding-left: 0px;margin-bottom: 0px;">
            <li class="list-group-item" style="width: 900px">
                <a href="">{{ foo.author.username }}</a>
                <span class="badge">评论时间:{{ foo.creat_time }}</span>
                <p>{{ foo.detail }}</p>
            </li>
        </ul>
    </div>
    <hr>

    <div>
        {% for foo in comment %}
        <h4>用户名：{{ foo.author.username }}
            <br>
            <small>全部评论</small>
        </h4>
        <ul style="padding-left: 0px;margin-bottom: 0px;">
            <li class="list-group-item" style="width: 900px">
                <a href="#">{{ foo.author.username }}</a>
                <span class="badge">评论时间:{{ foo.creat_time }}</span>
                <p>{{ foo.detail }}</p>
            </li>
        </ul>

    </div>
    <hr>

    <div>
        <h4>{{ user }}
            <br>
            <small>用户资料</small>
        </h4>

        <ul style="padding-left: 0px;margin-bottom: 0px;">
            <li class="list-group-item" style="width: 900px">用户：{{ username }}</li>
            <li class="list-group-item" style="width: 900px">编号：</li>
            <li class="list-group-item" style="width: 900px">昵称：</li>
        </ul>
    </div>

</div>

 主函数

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

向前端页面传递参数

<input type="hidden" name="sent_id" id="sent_id" value="{{ sen.id }}">

各个页面链接到个人中心

#首页用户名链接到个人中心
<a class="nickname" target="_blank" href="{{ url_for(‘usercenter‘,user_id=foo.author_id) }}">{{ foo.author.username }}</a>


#详情用户名连接到个人中心
  <a href="{{ url_for(‘usercenter‘,user_id=foo.author.id) }}">{{ foo.author.username }}</a>
