Question

问题：

在settings.py中启用DEFAULT_FILE_STORAGE会创建TypeError: Unicode-objects must be encoded before hashing（以下日志）

DEFAULT_FILE_STORAGE = ''创建TypeError
DEFAULT_FILE_STORAGE = 'app.aws.utils.MediaRootS3Boto3Storage'创建TypeError

我在做什么？

我试图为静态和放置设置S3存储空间媒体文件。
我特意尝试在我的AWS桶中的/ media /文件夹中启用photologue存储。

什么工作？

如果我在settings.py

#DEFAULT_FILE_STORAGE = 'app.aws.utils.MediaRootS3Boto3Storage'

我可以python manage.py collectstatic 并且我的所有静态文件都成功上传到aws上的/ static /文件夹
静态资产正在运作
媒体资产在本地正常运作

什么打破？

DEFAULT_FILE_STORAGE设置为任何值会创建此错误消息。

问题：

这是我安装的软件包的问题吗？

好的，所以我看到第二篇文章建议将该设置用于DEFAULT_FILE_STORAGE，但对我来说这看起来有点不寻常。

引用http://django-storages.readthedocs.io/en/latest/backends/amazon-S3.html，您将使用：

DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'

您的媒体根。

编辑：使用Prologue和S3，它只支持Python 2.7和旧的Boto库。

在settings.py中设置DEFAULT_FILE_STORAGE会破坏应用
