RQ作业已排队但未运行

Question

我在使用Python-RQ将作业排队时遇到问题，作业似乎排得很好，但它们不会运行、崩溃或执行任何必须执行的操作

我正在做的过程如下：

1. 在本地主机上运行redis server：

loren@RONDAN1:/mnt/c/Users/rondan$ sudo service redis-server restart
[sudo] password for loren:
Stopping redis-server: redis-server.
Starting redis-server: redis-server.
loren@RONDAN1:/mnt/c/Users/rondan$ rq info
default      | 0
1 queues, 0 jobs total

72a81f7d4cde4e7c865b178772766aef (RONDAN1 95): idle default
1 workers, 1 queues

1. 在其他bash上运行worker：

loren@RONDAN1:/mnt/c/Users/rondan$ rq worker --with-scheduler
19:26:42 Worker rq:worker:72a81f7d4cde4e7c865b178772766aef: started, version 1.7.0
19:26:42 Subscribing to channel rq:pubsub:72a81f7d4cde4e7c865b178772766aef
19:26:42 *** Listening on default...
19:26:42 Trying to acquire locks for default
19:26:42 Scheduler for default started with PID 98
19:26:42 Cleaning registries for queue: default

1. 运行我的python演示代码（此代码在不使用redis队列的情况下以异步方式工作）：

main.py

import lightquery as lq
from datetime import datetime, timedelta
import time
from redis import Redis
from rq import Queue

queue = Queue(connection=Redis())


def queue_tasks():
    queue.enqueue(lq.print_task, 5)
    queue.enqueue_in(timedelta(seconds=10), lq.print_numbers, 5)


def main():
    queue_tasks()

if __name__ == "__main__":
    main()

lightquery.py

import time

def print_task(seconds):
    print("Starting task")
    for num in range(seconds):
        print(num, ". Hello World!")
        time.sleep(1)
    print("Task completed")


def print_numbers(seconds):
    print("Starting num task")
    for num in range(seconds):
        print(num)
        time.sleep(1)
    print("Task to print_numbers completed")

1. 运行代码后，执行将正确结束，作业将进入队列：

loren@RONDAN1:/mnt/c/Users/rondan$ rq worker --with-scheduler
19:26:42 Worker rq:worker:72a81f7d4cde4e7c865b178772766aef: started, version 1.7.0
19:26:42 Subscribing to channel rq:pubsub:72a81f7d4cde4e7c865b178772766aef
19:26:42 *** Listening on default...
19:26:42 Trying to acquire locks for default
19:26:42 Scheduler for default started with PID 98
19:26:42 Cleaning registries for queue: default
19:28:43 default: lightquery.print_task(5) (02a07849-64b5-4f44-8e0b-89bb466110ee)

在将作业添加到作业队列后，我尝试显示作业队列，并打印一个空数组（也许这可以帮助您提供解决方案）

Answer 1

解决了，问题是我导入模块的方式

使用

from lightquery import print_task
...
queue.enqueue(print_task, 5)

而不是：

import lightquery as lq
...
queue.enqueue(lq.print_task(), 5)
