如何立即运行芹菜时间表？

问题描述

我有一个这样配置的芹菜计划：

I have a celery schedule which is configured like this:

CELERYBEAT_SCHEDULE = {
    "runs-every-30-seconds": {
        "task": "tasks.refresh",
        "schedule": timedelta(hours=1)
    },
}

测试后，我发现这个时间表在1小时后开始，但我想运行1小时后立即安排。

After testing I find that this schedule is started after 1 hour, but I want to run this schedule instantly and again after 1 hour.

推荐答案

如果您的意思是启动时，请在（django 1.7中的新增内容）：

If you mean at startup, do it in AppConfig.ready() (new in django 1.7):

# my_app/__init__.py:

class MyAppConfig(AppConfig):
    def ready(self):
        tasks.refresh.delay()

另见：

如果你只是为了测试， d直接调用/延迟任务，而不是测试芹菜调度器本身。

If you're only doing this for the tests, I'd rather call/delay the tasks directly than testing the celery scheduler itself.
