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('/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) 
    db.session.commit()

 

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

 <input type="hidden" name="questions_id" value="{{ questions.id }}">

  

3、显示评论次数

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

  

4、要求评论前登录

@app.route('/comments/',methods=['POST'])
@loginFirst
