完成评论

 

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

 

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

#评论页
@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)  # 保存到数据库
    db.session.commit()  # 提交
    return redirect(url_for('detail',questions_id=questions_id))

 

2.用<input type="hidden" 方法获取前端的"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.显示评论次数

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

 

4.要求评论前登录

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