完成評論

 

1. 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
2. 用<input type="hidden" 方法獲取前端的"question_id" 
3. 顯示評論次數
4. 要求評論前登陸
5. 嘗試實現詳情頁面下的評論列表顯示

 

1.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

#評論頁
@app.route('/comments/',methods=['POST'])
@loginFirst
def comments():
    comment=request.form.get('new_comment')
    questions_id =request.form.get('questions_id')
    author_id = User.query.filter(User.username == session.get('user')).first().id
    comments = Comment(detail=comment, author_id=author_id, questions_id=questions_id)
    db.session.add(comments)  # 保存到數據庫
    db.session.commit()  # 提交
    return redirect(url_for('detail',questions_id=questions_id))

 

2.用<input type="hidden" 方法獲取前端的"question_id" 

@app.route('/answer/', methods=['GET', 'POST'])
def answer():
    if request.method == 'POST':
        question_id = request.form.get('question_id')
        author_id = request.form.get('author_id')
        detail = request.form.get('detail')
        comment = Comment(question_id=question_id, author_id=author_id, detail=detail)
        db.session.add(comment)
        db.session.commit()
        return redirect(url_for('detail',question_id=question_id))

 

3.顯示評論次數

<h4>評論({{ questions.comments|length }})</h4>

 

4.要求評論前登陸

1 #評論頁
2 @app.route('/comments/',methods=['POST'])
3 @loginFirst
