完成评论功能

1.定义评论的视图函数
@app.route('/comment/',methods=['POST'])
def comment()：
读取前端页面数据，保存到数据库中

@app.route('/comment/',methods=['POST'])
@loginFirst
def comment():
        comment = request.form.get('new_comment')
        ques_id = request.form.get('question_id')
        auth_id = User.query.filter(User.username == session.get('user')).first().id
        comm = Comment( detail=comment, question_id=ques_id,author_id=auth_id)
        db.session.add(comm)
        db.session.commit()
        return redirect(url_for('detail',question_id = ques_id))

 

 

2.用<input type="hidden" 方法获取前端的"question_id" 

3.显示评论次数

4.要求评论前登录

5.尝试实现详情页面下的评论列表显示

{% extends'base.html' %}
{% block title %}
    detail
{% endblock %}
{#{% block head %}#}
{#    <link rel="stylesheet" href="{{ url_for('static',filename='css/detail.css')}}" type="text/css">#}
{#{% endblock %}#}
{% block main %}
<body>
<div class="post">

<h3 class="title ">{{ques.title}}<br><small>{{ ques.author.username }}<span>{{ ques.create_time }} </span>  </small></h3>
</div>
    <p style="color: #333;">{{ ques.detail }}</p>
    <hr>
    <form action="{{ url_for('comment') }}"method="post">
    <div class="new-comment">
        <textarea name="new_comment" id="new-comment" cols="85" rows="5" placeholder="write your comment"></textarea>
        <input name="question_id" type="hidden" value="{{ ques.id }}" />
    </div>
    <button class="btn-send" type="submit">发送</button>
    </form>

<h4>评论:({{ ques.comment | length }})</h4>
 <ul class="list">
       {% for foo in ques.comments %}
       <li class="post_item">
           <a href="#" class="light">{{foo.author.username }}</a>
           <br>
           <p class="post_item">{{ foo.detail }}</p>
           <span class="foot">发布于  {{ foo.create_time }}</span>
       </li>
       <hr>
{% endfor %}
   </ul>
</body>
{% endblock %}
