Enquanto tentava iniciar o trabalhador, tive um problema:
ImportError: nenhum módulo chamado 'projeto'

Traceback (última chamada mais recente):

ImportError: No module named 'project'

Estou usando um aipo e um redis no ubuntu16.04. A seguir estão minhas etapas de processamento:

Primeiro instale o aipo e os redis:

pip install -U celery[redis] 

sudo apt-get install redis-server

Quando eu uso:

ps aux|grep redis

Eu posso ver que o redis está listando a porta 6379

Segundo no project.setting, adicione:

#Broker 
BROKER_URL = 'redis://127.0.0.1:6379/0'
BROKER_TRANSPORT = 'redis' 

Terceiro, construa o celery.py na pasta do projeto, project.setting também está nesta pasta:

from __future__ import absolute_import
import os
import django
from celery import Celery
from django.conf import settings

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings')
django.setup()
app = Celery('project')
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

A seguir, crie o task.py no aplicativo que o utilizará

from project.celery import app


from random import Random
from django.core.mail import send_mail

from users.models import EmailVerifyRecord
from project.settings import EMAIL_FROM


@app.task
def random_str(randomlength=8):
    str = ''
    chars = 'AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz0123456789'
    length = len(chars) - 1
    random = Random()
    for i in range(randomlength):
        str += chars[random.randint(0, length)]
    return str

Após todas essas etapas, no mesmo caminho de aipo.py, eu corro:

celery -A project worker -l debug

E então eu entendi o problema.

Qualquer amigo pode ajudar?

Muito obrigado!
