定義評論的視圖函數
@app.route('/comment/',methods=['POST'])
def comment()：
讀取前端頁面數據，保存到數據庫中
用<input type="hidden" 方法獲取前端的"question_id"
顯示評論次數
要求評論前登陸
嘗試實現詳情頁面下的評論列表顯示

視圖函數：css

@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))
