计划一个redis作业，该作业使用pythonrq计划另一个redis作业

我有两种作业：一种是串行运行，另一种是并行并发运行。但是，我希望并行作业以串行方式进行调度（如果您仍在跟踪）。即:

做A

等A，做B

等待B，同时执行2个以上版本的C

我认为它有两个redis队列，一个只有一个工人的串行队列。和一个并行队列，其中有多个工作队列

serial_queue.schedule(
    scheduled_time=datetime.utcnow(),
    func=job_a,
     ...)    
serial_queue.schedule(
    scheduled_time=datetime.utcnow(),
    func=job_b,
     ...)

def parallel_c():
    for task in range(args.n_tasks):
        queue_concurrent.schedule(
            scheduled_time=datetime.utcnow(),
            func=job_c,
            ...)

serial_queue.schedule(
    scheduled_time=datetime.utcnow(),
    func=parallel_c,
     ...)

但是当前的设置给出了一个错误

属性错误：模块“\uuu main\uuuuuuuuu”没有属性“schedule\u fetch\u tweets”

。如何为

pythonrq

正确打包此函数？

解决方案需要一些技巧，因为您必须像导入外部模块一样导入当前脚本

比如说。

schedule\u twitter\u jobs.py

的内容如下：

from redis import Redis
from rq_scheduler import Scheduler
import schedule_twitter_jobs
# we are importing the very module we are executing

def schedule_fetch_tweets(args, queue_name):
    ''' This is the child process to schedule'''

    concurrent_queue = Scheduler(queue_name=queue_name+'_concurrent', connection=Redis())
    # this scheduler is created based on a queue_name that will be passed in
    for task in range(args.n_tasks):
        scheduler_concurrent.schedule(
            scheduled_time=datetime.utcnow(),
            func=app.controller.fetch_twitter_tweets,
            args=[args.statuses_backfill, fill_start_time])

serial_queue = Scheduler(queue_name='myqueue', connection=Redis())
serial_queue.schedule(
'''This is the first schedule.'''
   scheduled_time=datetime.utcnow(),
   func=schedule_twitter_jobs.schedule_fetch_tweets,
   #now we have a fully-qualified reference to the function we need to schedule.
   args=(args, ttl, timeout, queue_name)
   #pass through the args to the child schedule
   )
