我的应用程序图像上传在 localhost 上运行良好，但是当我部署到 Heroku 时，它给了我属性错误和运行时错误。我该如何解决这个问题？

我按照这里的一些人的建议删除了表单中文件字段上的验证器，但它没有解决问题

    if request.method == 'POST':
        if form.validate_on_submit():
            filename = images.save(request.files['post_image'])
            url = images.url(filename)
            new_post = Post( form.post_title.data,

    else:

        flash('ERROR! Share item was not added.', 'error')

我想成功地将图像文件上传到我的远程数据库，但我不断从 Heroku 收到这些错误消息。
