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挂钩到我的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,AWS_STORAGE_BUCKET_NAME
的值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。谢谢你的阅读。
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')
这是我在尝试通过'heroku run'或Procfile中收集静态时获得的回溯:

答案 0 :(得分:14)
您没有说from s3utils import *
,因此永远不会将AWS_STORAGE_BUCKET_NAME
导入设置模块。
S3BotoStorage
会从环境变量中提取AWS_ACCESS_KEY_ID
和AWS_SECRET_ACCESS_KEY
,但必须在AWS_STORAGE_BUCKET_NAME
中设置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
和AWS_SECRET_ACCESS_KEY
实际上是boto
参数而AWS_STORAGE_BUCKET_NAME
不是(boto
将从env vars)。*
对s3utils的其他引用是明确的:
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(12-Factor App, anyone?)的其他设置,并且我正在考虑打开一个问题/提交拉取请求。
