Shrine 2.12.0

New features​

  • The Shrine::Attacher#assign_remote_url method has been added, which acts the same as #remote_url= but allows you to also dynamically provide options to the underlying downloader (Down.download by default).
attacher.assign_remote_url("https://example.com/image.jpg", downloader: { 'Cookie' => 'abc123' })

  • The Shrine::UploadedFile#download_url method has been added to the download_endpoint plugin for explicitly generating the file URL through the download endpoint.

  • The :redirect option has been added to download_endpoint plugin, which makes download URLs redirect directly to the uploaded file on its storage. This allows you to avoding streaming the file through your app, and thus not having it impact your request throughput.

  • The Shrine::Plugins::ValidationHelpers::PRETTY_FILESIZE callbable has been added, which takes the filesize in bytes and returns the representation in correct unit. This can be used when providing custom validation error messages.

pretty_filesize = Shrine::Plugins::ValidationHelpers::PRETTY_FILESIZE
pretty_filesize.call(1*1024)           #=> "1.0 KB"
pretty_filesize.call(1.5*1024*1024)    #=> "1.5 MB"
pretty_filesize.call(2*1024*1024*1024) #=> "2.0 GB"

Other improvements​

  • The Shrine::Storage::FileSystem#open now forwards any additional options to File.open.

  • The Shrine::Storage::S3#open method now accepts the :rewindable option to disable caching read content to disk.

  • In validation error messages in filesize validators in the validation_helpers plugin show specified limits in the appropriate unit, instead of always using megabytes.

  • Shrine::UploadedFile#open will now always open a new IO object, and close the previous one. This way the uploaded file will be reopened if it's closed.

  • Fixed possible encoding issues in Shrine::Storage::S3#upload when filesize is unknown.

  • The registered storage resolvers in the dynamic_storage plugin are now correctly inherited upon subclassing.

  • The :file MIME type analyzer from determine_mime_type plugin will now raise an explicit Shrine::Error when the subprocess from the shell command failed to be spawned.

  • Attacher#data_uri= and Attacher#remote_url= in addition to "" now also ignore nil values, instead of raising an exception.

Backwards compatibility​

  • The :storages option has been deprecated in the download_endpoint plugin in favour of the new Shrine::UploadedFile#download_url method.

  • The deprecation of assigning cached versions has been undone, as it can be a useful feature.
