나는 이미 2주 후에 처음으로 샐러리를 사용해 왔기 때문에 작업 대기열에 꽤 신선합니다. 내가 현재 직면하고 있는 문제는 Django 및 ModuleNotFoundError 오류를 통한 셀러리 사용과 관련이 있습니다.

Django 1.11 및 celery 4.2.0 있습니다. 내 파일은 다음과 같습니다.

celery_tasks.py

from celery import Celery
from celery import task
import os

app = Celery('myapp')                         
#app.config_from_object('myapp.celeryconfig', namespace='CELERY')  # WORKS WHEN CALLED THROUGH VIEW/DJANGO: Tell Celery instance to use celeryconfig module
app.config_from_object('celeryconfig', namespace='CELERY')  # WORKS WHEN CALLED THROUGH TERMINAL

# set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myapp.celeryconfig')

suf = lambda n: "%d%s" % (n, {1: "st", 2: "nd", 3: "rd"}.get(n if n < 20 else n % 10, "th"))
@app.task(name='celery_tasks.fav_doctor')
def fav_doctor():
    """Reads doctor.txt file and prints out fav doctor, then  addsa new
    number to the file"""

    with open('doctor.txt', 'r+') as f:
        for line in f:
            nums = line.rstrip().split()

            print ('The {} doctor is my favorite'.format(suf(int(nums[0]))))

            for num in nums[1:]:
                print ('Wait! The {} doctor is my favorite'.format(suf(int(num))))

            last_num = int(nums[-1])
            new_last_num = last_num + 1

            f.write(str(new_last_num) + ' ')


@app.task(name='celery_tasks.reverse')
def reverse(string):
    return string[::-1]

@app.task(name='celery_tasks.add')
def add(x, y):
    return x+y


if __name__ == '__main__':
    app.start()

celeryconfig.py

from __future__ import absolute_import, unicode_literals
from datetime import timedelta

## List of modules to import when celery starts.

}

__초기화__.py

from .celery_tasks import app as celery_app # Ensures app is always imported when Django starts so that shared_task will use this app.

__all__ = ['celery_app']

--> 마이앱-- __init__.py-- celery_tasks.py-- celeryconfig.py--> 조회수-- admin_scripts.py

셀러리 파일이 있는 디렉터리로 이동하여 가상 환경으로 전환한 후 다음을 입력합니다.

celery -A celery_tasks worker -l info

그러나 내 celery_tasks.py 파일의 이 구성에서만:

#app.config_from_object('myapp.celeryconfig', namespace='CELERY')  # WORKS WHEN CALLED THROUGH VIEW/DJANGO: Tell Celery instance to use celeryconfig module
app.config_from_object('celeryconfig', namespace='CELERY')  # WORKS WHEN CALLED THROUGH TERMINAL

위의 코드 줄을 재구성한 후에만 Django를 통해 셀러리를 사용할 수 있으므로 다음과 같이 하십시오.

app.config_from_object('myapp.celeryconfig', namespace='CELERY')  # WORKS WHEN CALLED THROUGH VIEW/DJANGO: Tell Celery instance to use celeryconfig module
#app.config_from_object('celeryconfig', namespace='CELERY')  # WORKS WHEN CALLED THROUGH TERMINAL

이 단계를 수행하지 않으면 오류 메시지가 표시되고 중간에 변경하지 않고 이와 같이 구성합니다. 즉,

app.config_from_object('myapp.celeryconfig', namespace='CELERY') # VIEW/DJANGO를 통해 호출될 때 작동: Celery 인스턴스에 celeryconfig 모듈을 사용하도록 지시

app.config_from_object('celeryconfig', namespace='CELERY') # 터미널을 통해 호출될 때 작동

그런 다음이 오류가 발생합니다.

정확히 어디가 잘못되었는지 알 수 없습니다. 내 원래 목표에 대한 간략한 설명으로: 다양한 작업에서 검색된 정보를 새 창에 인쇄하고 싶습니다. 진행률 표시줄과 같지만 백분율 대신 출력이 터미널에서 볼 수 있는 것과 같습니다.
감사 해요.
