Django，芹菜主管：密钥错误：Django.core.exceptions。配置错误：密钥设置不能为空

Question

我有一个django1.11.4、python3.5、gunicorn19.7.1服务器，带有supervisor、redis2.10.6和cellery 4.1.0。在

我的文件结构如下：

samy_python
├── celery.py
├── __init__.py
├── settings
├── urls.py
├── wsgi.py
website
├── static
├── templates
├── samy
|    ├── samy_firebase.py
|    ├── tasks.py
├── views.py

我的秘密来自：

^{pr2}$

我的主管配置文件是：

[program:gunicorn]

....
environment = secret_KEY="12345"
.....

[program:celery]
directory=/home/username/Projects/samy/samy_python
command=/home/username/Projects/samy/samy_python/env/bin/celery --app=samy_python.celery.app worker -B -l info
user=username
stdout_logfile=/var/log/celery/celery.log
stderr_logfile=/var/log/celery/celery.log
autostart=false
autorestart=false
startsecs=10

我的芹菜档案：

# celery.py

from __future__ import absolute_import
import os
import logging
logger = logging.getLogger('myapp.celery.py')

from celery import Celery
from django.conf import settings

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "samy_python.settings")

# Celery App
# TODO
# [START Celery App]
app = Celery('samy_python')
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

# [END Celery App]

我的初始化文件：

# __init__.py

from __future__ import absolute_import
from .celery import app as celery_app

我的配置设置.py芹菜档案：

BROKER_URL = 'redis://localhost:6379/1'
CELERY_RESULT_BACKEND = 'redis://localhost:6379/1'
CELERY_ACCEPT_CONTENT = ['application/json']
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'

错误可能来自我的设置.py文件我使用一个env变量来设置环境。（生产、开发或测试）：

DEBUG = False
DJANGO_TESTING = False
DJANGO_DEVELOPMENT = False
DJANGO_ENV = os.environ.get('DJANGO_ENV')

if DJANGO_ENV == 'DJANGO_TESTING':
    DJANGO_TESTING = True
elif DJANGO_ENV == 'DJANGO_DEVELOPMENT':
    DJANGO_DEVELOPMENT = True

然后设置firebase凭证和googleapi凭证。然后我从公司内部获得证书，比如，萨米_firebase.py有：

from django.conf import settings
if settings.DJANGO_TESTING == True:
    logger.info('Firebase Config: Test DB')

我不确定最后一部分是否相关，但以下是我一直收到的错误：

During handling of the above exception, another exception occurred:

另外，gunicorn工作得很好，所以如果我不启动celry程序，它就会接收到环境变量。如果我在设置.py文件，开始。在

Answer 1

在env中设置密钥，如下所示：

export SECRET_KEY="#mysecret_key"

并检查：

^{pr2}$

在django设置中，更改为：

SECRET_KEY = os.environ.get("SECRET_KEY")

有关详细的参考检查：Read and Set Environment Variables

Answer 2

将环境变量添加到supervisor conf文件的[program:celery]部分。目前它只设置为gunicorn。在
