セロリを使って数週間経ちましたので、タスクキューイングはかなり新鮮です。 私が現在直面している問題は、Djangoを介したセロリの使用とModuleNotFoundErrorエラーに関連しています。

Django 1.11とcelery 4.2.0ます。 私のファイルは次のとおりです。

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.
CELERY_IMPORTS = ['celery_tasks',]

## Message Broker (RabbitMQ) settings.
BROKER_URL = 'amqp://'
BROKER_PORT = 5672

## Result store settings.
CELERY_RESULT_BACKEND = 'rpc://' 

## Worker settings
#CELERYD_CONCURRENCY = 1
#CELERYD_TASK_TIME_LIMIT = 20
#CELERYD_LOG_FILE = 'celeryd.log'
#CELERYD_LOG_LEVEL = 'INFO'

## Misc
#CELERY_IGNORE_RESULT = False
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'
CELERY_ACCEPT_CONTENT=['json']
CELERY_TIMEZONE = 'Europe/Berlin'
CELERY_ENABLE_UTC = True

CELERYBEAT_SCHEDULE = {
    'doctor-every-10-seconds': {
        'task': 'celery_tasks.fav_doctor',
        'schedule': timedelta(seconds=3),
    },
}

__init__。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']

-> myapp--__init__.py--celery_tasks.py--celeryconfig.py->ビュー--admin_scripts.py

セロリファイルが配置されているディレクトリに移動し、仮想環境に切り替えた後、次のように入力します。

celery -A celery_tasks worker -l info

しかし、私のcelery_tasks.pyファイルのこの構成でのみ：

#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

上記のコード行を再構成した後でのみ、Django経由でセロリを使用できます。

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

この手順を実行しないと、エラーメッセージが表示され、途中で変更せずにそのように構成されます。

app.config_from_object（ 'myapp.celeryconfig'、namespace = 'CELERY'）＃ビュー/ DJANGOを介して呼び出された場合に機能：Celeryインスタンスにceleryconfigモジュールを使用するように指示します

app.config_from_object（ 'celeryconfig'、namespace = 'CELERY'）＃ターミナルを介して呼び出された場合に機能します

次に、このエラーが表示されます。

どこが間違っているのか正確にはわかりません。 私の当初の目的の簡単な説明として、さまざまなタスクから取得した情報を新しいウィンドウに印刷したいので、プログレスバーのように、パーセンテージではなく、ターミナルに表示されるものと同じように出力します。
ありがとう。
