主管、芹菜、Virtualenvwrapper、Django：即使将 pythonpath 添加到环境中，也无法导入 django 设置

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。在活动 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

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 Audrey 和 Danny 在 Two Scoops of Django 中推荐的方式，其要点是：

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

...从现在开始显式调用我的设置文件，例如
python manage.py runserver --settings='settings.production'
...从 base.py 导入并具有所有特定于生产的设置。
</aside>

...我在 virtualenvwrapper postactivate 文件中导出了 BTJC_STATE，除了通过主管运行 celeryd 我没有激活任何东西，因此完全跳过了该文件！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 是提出这个问题的更好方法。因此，通过更改我的 .conf 文件中的以下一行，它开始完美运行。

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

现在可以了，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 密钥等）的好方法，以便在未激活的使用中很好地工作虚拟环境。

欢迎所有建议，给我发消息，我会用解决方案更新这个=）
