Question

我已经使用 https://pypi.org/project/django-crontab/ 教程来安排玉米作业，但它不起作用：我加了

    INSTALLED_APPS = [
    ...,
    'django_crontab',
    ]
    
    CRONJOBS = [
        ('*/1 * * * *', 'allActivitiesApp.cron.sendNotification', '>> /path/to/log/file.log'),
    ]

在 allActivitiesApp ->corn.py:

    from .models import *
    
    def sendNotification():
        # notificationList = dateBasedNotificaton.objects.filter(scheduleDate = date.today())
        obj = test(name="working")
        obj.save()
        obj.refresh_from_db()
        # print("sending notifications/messages")
        return "success"

但是当我尝试获取我发现的日志时它没有做任何事情：

我在邮件中没有收到任何日志。

我该如何解决这个问题...？

Answer 1

我认为您的文件名有问题：

In allActivitiesApp -> corn.py:

文件名应该是 cron.py 而不是 corn.py。

第二个原因可能是您没有运行命令：

python manage.py crontab add

将所有定义的作业从 CRONJOBS 添加到 crontab

要显示此项目的当前活动作业：

python manage.py crontab show

为什么使用玉米的预定工作在 Django 中不起作用？
