Django存储没有检测到更改的静态文件

Question

我正在使用django-storages和amazon s3作为我的静态文件。 在文档之后，我将这些设置放在我的settings.py中

STATIC_URL = 'https://mybucket.s3.amazonaws.com/'

ADMIN_MEDIA_PREFIX = 'https://mybucket.s3.amazonaws.com/admin/'

INSTALLED_APPS += (
    'storages',
)

DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
AWS_ACCESS_KEY_ID = 'mybucket_key_id'
AWS_SECRET_ACCESS_KEY = 'mybucket_access_key'
AWS_STORAGE_BUCKET_NAME = 'mybucket'
STATICFILES_STORAGE = 'storages.backends.s3boto.S3BotoStorage'

我第一次运行收集静态一切正常，我的静态文件上传到我的s3桶。

但是，在对我的静态文件进行更改并运行python manage.py collectstatic尽管静态文件已被修改，但python manage.py collectstatic输出

-----> Collecting static files
    0 static files copied, 81 unmodified.

但是，如果我重命名更改的静态文件，更改的静态文件将正确复制到我的s3存储桶。

为什么django-storage上传我更改的静态文件？ 是配置问题还是问题更严重？

Answer 1

如果“目标”文件比源文件“更年轻”，则collectstatic会跳过文件。 似乎亚马逊S3存储返回错误的日期为您的文件。

你可以调查[code] [1]并调试服务器响应。 也许时区存在问题。

或者您可以将--clear参数传递给collectstatic，以便在收集之前在S3上删除所有文件

Answer 2

https://github.com/antonagestam/collectfast

来自readme.txt：自定义管理命令，用于比较来自S3的MD5总和和etag以及两者是否相同的跳过文件副本。 如果您使用git作为更新时间戳的源控制系统，这使得运行collect static MUCH更快。

Answer 3

使用此配置创建仅用于collectstatic同步的设置文件：

TIME_ZONE = 'UTC'

使用以下行运行具有特定设置的collectstatic：

python manage.py collectstatic --settings=settings.collectstatic

Answer 4

这个问题有点旧，但如果将来有人帮助，我想我会分享我的经验。 根据其他主题中的建议我确认，对我来说，这确实是由时区差异造成的。 我的django时间不正确，但设置为EST，S3设置为GMT。 在测试中，我恢复了django-storages 1.1.5，它确实似乎得到了收集静态工作。 部分由于个人偏好，我不愿意a）回滚三个版本的django-storage并丢失任何潜在的错误修复或b）改变我项目组件的时区，这基本上归结为一个便利功能（尽管很重要）一）。

我写了一个简短的脚本来完成与collectstatic相同的工作而没有上述改动。 它需要对您的应用进行一些修改，但如果它放在应用程序级别并且'static_dirs'替换为项目应用程序的名称，则应该适用于标准情况。 它通过终端运行'python whatever_you_call_it.py -e environment_name（将其设置为你的aws存储桶）。
