javascript - 为什么我注释所有cips变量，但仍然收到错误“ jinja2.exceptions.UndefinedError：'cips'未定义”？(Why do I comment all the cips variables and still get an error“jinja2.exceptions.UndefinedError: 'cips' is undefined”?)

Question

I encounter "Object of type 'Response' is not JSON serializable" which may cause by var cips when I am developing an article comment using flask.So I comment all cips,however,Pycharm still report error "jinja2.exceptions.UndefinedError: 'cips' is undefined", I really don't understand.

(我在使用flask开发文章注释时遇到“类型'Response'的对象不可JSON序列化”这可能是由var cips引起的。所以我注释了所有cips，但是，Pycharm仍然报告错误“ jinja2.exceptions.UndefinedError：” cips'未定义”，我真的不明白。)

Didn't I comment all the cips variables?

(我没有注释所有cips变量吗？)

Here is my html code(as you will see,I comment all cips)

(这是我的html代码（如您所见，我注释所有cips）)

This is python (I also not pass cips )

(这是python（我也没有通过cips）)

@app.route('/article/<article_id>')
def article(article_id):
    article = articleService.find_by_id(article_id)
    user = userService.find_by_id(article.user_id)
    ip = ipService.find_ip_by_ip(request.remote_addr)
    aip = ipService.find_aip_both(article_id, ip.id)
    comments = commentService.find_by_articleid(article_id)
    comments.reverse()
    # find all comment state related to this ip
    cips=[]
    for index in range(0,len(comments)):
        cips.append(jsonify((ipService.find_cip_by_both(comments[index].id,ip.id)).as_json()))

    if aip is None:  # 第一次访问
        aip = ArticleIp(ip_id=ip.id, article_id=article_id, vote_state=0)
        ipService.insert(aip)
        articleService.addAccess(article)
    # todo what the response means?
    return render_template('article.html', article=article, user=user, comments=comments, flag=0)
