无法使用boto通过Heroku将静态收集到s3-s3 bucket返回NoneType

Question

这个问题涉及使用Heroku,django-storages(w/boto for s3)和CloudFront来提供静态内容的设置.

在过去的几个小时里,我一直在努力将我的静态文件成功加载到我的Heroku应用程序中.我已成功将Cloudfront连接到我的s3存储桶,看起来好像存储桶设置正确,但无论出于何种原因,我的值AWS_STORAGE_BUCKET_NAME似乎都没有正确注册.

如果有人对如何调试这个有任何线索或想法,我会非常感激.我没办法.谢谢阅读.

settings.py(重要的东西):

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')

这是我尝试通过'heroku run'或Procfile中尝试collectstatic时获得的回溯:

    path = '/' + bucket

请注意,我已经省略了域名等,我在代码中实际上没有[域名]或[网站].

你不是说from s3utils import *,所以AWS_STORAGE_BUCKET_NAME永远不会导入到设置模块中.

S3BotoStorage将拉动AWS_ACCESS_KEY_ID和AWS_SECRET_ACCESS_KEY从环境变量,但AWS_STORAGE_BUCKET_NAME必须设置settings.py.这似乎是一个奇怪的不一致,但我认为这是因为AWS_ACCESS_KEY_ID并且AWS_SECRET_ACCESS_KEY实际上是boto参数而AWS_STORAGE_BUCKET_NAME不是(boto将从env vars中提取凭证).*

对s3utils的其他引用是显式的:

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

因此,唯一没有处理的设置是AWS_STORAGE_BUCKET_NAME,这会导致您的错误.

*我想看看django-storages接受来自env vars的其他设置(12-Factor App,任何人？),我正在考虑打开一个问题/提交一个拉取请求.
