  1. 显示所有评论
    {% for foo in ques.comments %}
    <ul class="list">
           {% for foo in ques.comments %}
           <li class="post_item">
               <a href="{{ url_for(\'usercenter\',user_id=foo.author.id) }}" class="light">{{foo.author.username }}</a>
               <br>
               <img width="48" height="48" class="pf" src="https://ss2.bdstatic.com/70cFvnSh_Q1YnxGkpoWK1HF6hhy/it/u=4066191998,32277144&fm=27&gp=0.jpg" alt="">
               <p class="post_item">{{ foo.detail }}</p>
               <span class="foot">发布于  {{ foo.create_time }}</span>
           </li>
           <hr>
    {% 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\'))
        question_id= db.Column(db.Integer, db.ForeignKey(\'question.id\'))
        create_time = db.Column(db.DateTime, default=datetime.now)
        detail=db.Column(db.Text,nullable=False)
        question= db.relationship(\'Question\',backref=db.backref(\'comments\',order_by=create_time.desc))
        author= db.relationship(\'User\', backref=db.backref(\'comments\'))

     

  3. 显示评论条数
    {{ ques.comments|length }}
    <a href="#" class="post_item_foot">评论:({{ foo.comments|length }})</a>
  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

@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)
{% extends\'base.html\' %}
{% block title %}个人中心 {% endblock %}

{% block head %}
<link rel="stylesheet" type="text/css" href="{{ url_for(\'static\',filename=\'css/detail.css\') }}">
{% endblock %}
{% block main %}
    <div class="post">
    <h3 class="title "><span>{{ username }}<br><small>全部问答</small></span></h3>
    <ul class="list">
         {% for foo in questions %}
       <li class="post_item">
           <a href="#" class="light">{{foo.author.username }}</a>
           <img width="48" height="48" class="pf" src="https://ss2.bdstatic.com/70cFvnSh_Q1YnxGkpoWK1HF6hhy/it/u=4066191998,32277144&fm=27&gp=0.jpg" alt="">
           <p class="post_item">{{ foo.detail }}</p>
           <span class="foot">发布于  {{ foo.create_time }}</span>
       </li>
       <hr>
{% endfor %}
    </ul>
    </div>

    <div class="post">
    <h3 class="title "><span></span>{{ user }}<br><small>全部评论  <span></span></small></h3>
    <ul class="list">
         {% for foo in comments %}
       <li class="post_item">
           <a href="#" class="light">{{foo.author.username }}</a>
           <img width="48" height="48" class="pf" src="https://ss2.bdstatic.com/70cFvnSh_Q1YnxGkpoWK1HF6hhy/it/u=4066191998,32277144&fm=27&gp=0.jpg" alt="">
           <p class="post_item">{{ foo.detail }}</p>
           <span class="foot">发布于  {{ foo.create_time }}</span>
       </li>
       <hr>
{% endfor %}
    </ul>
    </div>

    <div class="post">
        <h3 class="title "><span></span>{{ user }}<br><small>个人信息  <span></span></small></h3>
         <ul>
             <li class="post_item">用户:{{ username }}</li>
             <li class="post_item">编号:</li>
             <li class="post_item">昵称:</li>
             <li class="post_item">文章数:</li>
