小编Ray*_*ski的帖子

每次我成功发布请求时，我都会收到此消息。我知道这与实现重定向功能有关，因此您不会收到双重帖子，但我无法使其正常工作。这是我的代码。谢谢您的帮助。

def K8_Points_Test(request):
    if request.method == 'POST':
        form = K8PointsTestForm(request.POST)
        if form.is_valid():
            form.save(commit=False)
            class_name = form.cleaned_data.get('class_name')
            getstudents = Student.objects.filter(class_name = class_name)
            students = getstudents.all()
            context = {'form': form ,'students' : students , 'class_name': class_name}

我尝试在 Heroku 上托管的 Django 项目上运行计划任务，但是我的任务不断崩溃，我不知道如何解决这个问题。这是我在错误日志中收到的错误消息。我在 settings.py 中将时区设置为“America/New_York”，我什至尝试在 celery.py 中添加时区以尝试对其进行故障排除，但对其没有影响。我很感激你的帮助。谢谢
