django - 主管、 celery 、Virtualenvwrapper、Django : Could not import django settings even when pythonpath added to environment

Question

谁能看到我在这里做错了什么？无论我尝试什么，我似乎都无法将其设置为正确检测 Django 的设置。在事件 virtualenv 的终端中手动运行时工作正常。

主管

[program:celery_beetlejuice]
command = /home/padraic/.virtualenvs/beetlejuice/bin/python /home/padraic/CodeDev/beetlejuice/beetlejuice_django/manage.py celeryd -B -E -l INFO
directory=/home/padraic/CodeDev/beetlejuice/beetlejuice_django
environment=PYTHONPATH="/home/padraic/CodeDev/beetlejuice/beetlejuice_django", DJANGO_SETTINGS_MODULE="beetlejuice_django.settings"
user = padraic
autostart=true
autorestart=true
stdout_logfile=/home/padraic/CodeDev/beetlejuice/beetlejuice_django/logs/celeryd.log
stderr_logfile=/home/padraic/CodeDev/beetlejuice/beetlejuice_django/logs/celeryd.log

叹息...找出错误...

所以!我有我的 settings.py 文件，其中包含:

[settings.py]
import os
BEETLEJUICE_STATE = os.environ.get('BTJC_STATE',  None)

if BEETLEJUICE_STATE == 'LOCAL':
    from local_settings import *
elif BEETLEJUICE_STATE == 'DEV':
    from development_settings import *
elif BEETLEJUICE_STATE == 'PROD':
    from production_settings import *
else:
    raise ImportError

<aside>...这曾经是做事的正确方式(或者我被告知)。我打算改用奥黛丽和丹尼在两勺 Django 中推荐的方式，其要点是:

settings/
    __init__.py
    base.py
    local.py
    test.py
    production.py

...并从现在开始明确调用我的设置文件，例如
python manage.py runserver --settings='settings.production'...从 base.py 进口并具有所有特定于生产的设置。 </aside>
...我在 virtualenvwrapper 中导出了 BTJC_STATE postactivate文件，除了通过主管运行 celeryd 我没有激活任何东西，从而完全跳过该文件!这引发了 ImportError 但我没有意识到它是从哪里来的 =(

添加一个解释异常的字符串是个好主意......显然使用 ImproperlyConfigured是一个更好的方式来提出这个问题。因此，通过更改我的 .conf 文件中下面的一行，它开始完美运行。

[program:celery_beetlejuice]
<snip>
environment=BTJC_STATE='LOCAL'
<snip>

所以现在可以使用了，我很高兴，但我需要找到一种设置环境变量(如数据库密码、api key 等)的好方法，它可以在未激活的使用中的 virtualenv 中很好地工作。

欢迎所有建议，给我发消息，我会用解决方案更新这个 =)
