Question

我正在使用Celery在窗体的后台执行任务提交。在POST请求期间提交表单后，我有使用延迟方法创建了一个在后台执行的任务。此任务使用来处理其他网站上的某些点击操作 Selenium Web驱动程序并在任务后返回两个python列表执行。根据列表内容，我要显示弹出消息。

当我使用celery执行任务并运行Django网站时提交表单上的开发服务器，我收到错误消息： “ AsyncResult”对象不可迭代。”

请提出如何解决此问题的建议，然后继续进行操作。

这是我的代码段：通过网页上的硒操作获得的示例列表内容如下：
board_not_used_list = ['16123','14960']
board_mgr_permissions_not_present_list = [ '23456','45678']

        else:
            action = 'submit'
            model = ConcludeKeyIssues()

        message = ""   


        if request.method == 'POST':

            form = ConcludeKeyIssuesForm(request.POST, instance=model)

            if form.is_valid():
