celery autodiscover_tasks 不适用于 ValueError : Empty module name

Question

我试图在我的应用程序中重用 autodiscover_tasks 函数而不使用 django，但它总是在我的 celery.py 中执行 autodiscover_tasks 时抛出 ValueError: Empty module name

consumer/
        /__init__.py
        /celeryapp/
                  /__init__.py
                  /celery.py
                  /celeryconfig.py
        /test1/
              /__init__.py
              /tasks.py

我在消费者目录中执行 celery(/usr/bin/celery) 命令

$cd /path/to/consumer
$celery worker -A celeryapp.celery -l debug

celeryapp/celery.py:

from __future__ import absolute_import
from celery import Celery

app = Celery()
app.config_from_object('celeryapp.celeryconfig')
app.autodiscover_tasks(['test1'])

测试1/tasks.py:

from __future__ import absolute_import
from celeryapp.celery import app

@app.task
def add(x,y):
    return x+y

错误信息:

$ celery worker -A celeryapp.celery -l debug

Answer 1

在 autodiscover_tasks 调用之前，您应该:
1,os.environ.setdefault("DJANGO_SETTINGS_MODULE","dj_gaomu.settings")
2、django.setup()
