無法通過Heroku使用boto-s3桶收集靜態到s3返回無類型

Question

此問題與使用Heroku，django-storages（w/boto for s3）以及CloudFront用於靜態內容的設置有關。

我一直在嘗試過去的幾個小時成功地加載我的靜態文件到我的Heroku應用程序。我已經成功地將Cloudfront掛鉤到了我的s3存儲桶，並且看起來好像存儲桶已正確設置，但無論出於何種原因，我的AWS_STORAGE_BUCKET_NAME值似乎都沒有正確註冊。

如果任何人有任何關於如何調試的線索或想法，我會非常感激。我不知道該怎麼做。謝謝閱讀。

settings.py（重要的東西）：

try: 
    from settings_local import * 
except: 
    import s3utils 
DEBUG = False 
#s3 stuff 
DEFAULT_FILE_STORAGE = 's3utils.MediaRootS3BotoStorage' 
STATICFILES_STORAGE = 's3utils.StaticRootS3BotoStorage' 
STATIC_URL = 'https://[domain].cloudfront.net/' 
#use heroku postgres database 
import dj_database_url 
DATABASES['default'] = dj_database_url.config() 

s3utils.py

from storages.backends.s3boto import S3BotoStorage 
from django.utils.functional import SimpleLazyObject 
import os 

AWS_ACCESS_KEY_ID = os.environ['AWS_ACCESS_KEY_ID'] 
AWS_SECRET_ACCESS_KEY = os.environ['AWS_SECRET_ACCESS_KEY'] 
AWS_STORAGE_BUCKET_NAME = 'static.[website].org' 

StaticRootS3BotoStorage = lambda: S3BotoStorage(location='static') 
MediaRootS3BotoStorage = lambda: S3BotoStorage(location='media') 

這是回溯試圖collectstatic當我得到，或者通過 'Heroku上運行' 或Procfile：

請注意，我省略了域名等，我實際上沒有[域]或代碼中的[網站]。

您不是說from s3utils import *，因此AWS_STORAGE_BUCKET_NAME永遠不會導入到設置模塊中。

S3BotoStorage將從環境變量中拉出AWS_ACCESS_KEY_ID和AWS_SECRET_ACCESS_KEY，但AWS_STORAGE_BUCKET_NAME必須設置爲settings.py。這似乎是一個奇怪的不一致之處，但我認爲這是因爲AWS_ACCESS_KEY_ID和AWS_SECRET_ACCESS_KEY實際上boto參數和AWS_STORAGE_BUCKET_NAME沒有（boto將拉動憑證從ENV瓦爾）*

到s3utils的引用文件，明確：

DEFAULT_FILE_STORAGE = 's3utils.MediaRootS3BotoStorage' 
STATICFILES_STORAGE = 's3utils.StaticRootS3BotoStorage' 

因此，唯一沒有注意的設置是AWS_STORAGE_BUCKET_NAME，並且導致您的錯誤。

*我想看看django-storages接受來自env vars（12-Factor App, anyone?）的其他設置，並且正在考慮爲此打開一個問題/提交pull請求。
