如何从Redis中在rq中排队一个任务

Question

我需要从mysql数据库中获取一些函数和它们执行的时间，然后把这些信息保存到redis里。接下来，我想从redis中按照规定的时间来执行这些函数。我想用rq这个工具来做调度，但我还不知道应该用什么样的格式把导入的数据保存到redis中。其实我对python和redis都很陌生。

如果你安装了redis，会有一个文件（对我来说是 ~/lib/python2.7/site-packages/rq/queue.py，这个文件又会调用job.py），里面清楚地说明了enqueue和enqueue_call这两个函数的作用：

def enqueue_call(self, func, args=None, kwargs=None,
                 timeout=None, result_ttl=None, description=None,
                 depends_on=None):
    """Creates a job to represent the delayed function call and enqueues it.

    It is much like `.enqueue()`, except that it takes the function's args
    and kwargs as explicit arguments.  Any kwargs passed to this function
    contain options for RQ itself.
    etc...."""

def enqueue(self, f, *args, **kwargs):
    """Creates a job to represent the delayed function call and enqueues it.

    Expects the function to call, along with the arguments and keyword
    arguments.
    etc...."""
