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
    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

视图函数：

@app.route('/xiangqing/<question_id>')
def xiangqing(question_id):
        quest = Question.query.filter(Question.id == question_id).first()
        return render_template('xiangqing.html',ques=quest)

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

详情页面html

{% extends'shouye.html' %}
{% block title %}
问答详情页

{% block jiemian %}
<body bgcolor="antiquewhite"><link rel="stylesheet" type="text/css" href="../static/css/cc.css">

                    <p class="nr">{{ foo.detail }}</p></td></tr>
                {% endfor %}
            </table>
