篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了评论列表显示及排序,个人中心显示相关的知识,希望对你有一定的参考价值。

  1. 显示所有评论
    {% for foo in ques.comments %}

  2. 所有评论排序
    uquestion = db.relationship(‘Question‘, backref=db.backref(‘comments‘, order_by=creat_time.desc))

  3. 显示评论条数
    {{ ques.comments|length }}

  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

PY:

@app.route(/user/<username_id>)
def yonghu(username_id):
    user = User.query.filter(User.id == username_id).first()
    context = {
        username:user.username,
        fabus:user.fabu,
        comments:user.comments
    }
    return render_template(yonghu.html,**context)
