rails--rails/activestorage/CHANGELOG.md

• Setting custom metadata on blobs are now persisted to remote storage.

  joshuamsager

• Support direct uploads to multiple services.

  Dmitry Tsepelev

• Invalid default content types are deprecated

  Blobs created with content_type image/jpg, image/pjpeg, image/bmp, text/javascript will now produce a deprecation warning, since these are not valid content types.

  These content types will be removed from the defaults in Rails 7.1.

  You can set config.active_storage.silence_invalid_content_types_warning = true to dismiss the warning.

  Alex Ghiculescu

Rails 7.0.0.alpha2 (September 15, 2021)

• No changes.

Rails 7.0.0.alpha1 (September 15, 2021)

• Emit Active Support instrumentation events from Active Storage analyzers.

  Fixes #42930

  Shouichi Kamiya

• Add support for byte range requests

  Tom Prats

• Attachments can be deleted after their association is no longer defined.

  Fixes #42514

  Don Sisco

• Make vips the default variant processor for new apps.

  See the upgrade guide for instructions on converting from mini_magick to vips. mini_magick is not deprecated, existing apps can keep using it.

  Breno Gazzola

• Deprecate ActiveStorage::Current.host in favor of ActiveStorage::Current.url_options which accepts a host, protocol and port.

  Santiago Bartesaghi

• Allow using IAM when signing URLs with GCS.

  gcs:
    service: GCS
    ...
    iam: true
  

  RRethy

• OpenSSL constants are now used for Digest computations.

  Dirkjan Bussink

• Deprecate config.active_storage.replace_on_assign_to_many. Future versions of Rails will behave the same way as when the config is set to true.

  Santiago Bartesaghi

• Remove deprecated methods: build_after_upload, create_after_upload! in favor of create_and_upload!, and service_url in favor of url.

  Santiago Bartesaghi

• Add support of strict_loading_by_default to ActiveStorage::Representations controllers.

  Anton Topchii, Andrew White

• Allow to detach an attachment when record is not persisted.

  Jacopo Beschi

• Use libvips instead of ImageMagick to analyze images when active_storage.variant_processor = vips.

  Breno Gazzola

• Add metadata value for presence of video channel in video blobs.

  The metadata attribute of video blobs has a new boolean key named video that is set to true if the file has an video channel and false if it doesn't.

  Breno Gazzola

• Deprecate usage of purge and purge_later from the association extension.

  Jacopo Beschi

• Passing extra parameters in ActiveStorage::Blob#url to S3 Client.

  This allows calls of ActiveStorage::Blob#url to have more interaction with the S3 Presigner, enabling, amongst other options, custom S3 domain URL Generation.

  blob = ActiveStorage::Blob.last
  
  blob.url # => https://<bucket-name>.s3.<region>.amazonaws.com/<key>
  blob.url(virtual_host: true) # => # => https://<bucket-name>/<key>
  

  josegomezr

• Allow setting a Cache-Control on files uploaded to GCS.

  gcs:
    service: GCS
    ...
    cache_control: "public, max-age=3600"
  

  maleblond

• The parameters sent to ffmpeg for generating a video preview image are now configurable under config.active_storage.video_preview_arguments.

  Brendon Muir

• The ActiveStorage video previewer will now use scene change detection to generate better preview images (rather than the previous default of using the first frame of the video). This change requires FFmpeg v3.4+.

  Jonathan Hefner

• Add support for ActiveStorage expiring URLs.

  rails_blob_path(user.avatar, disposition: "attachment", expires_in: 30.minutes)
  
  <%= image_tag rails_blob_path(user.avatar.variant(resize: "100x100"), expires_in: 30.minutes) %>
  

  If you want to set default expiration time for ActiveStorage URLs throughout your application, set config.active_storage.urls_expire_in.

  aki77

• Allow to purge an attachment when record is not persisted for has_many_attached.

  Jacopo Beschi

• Add with_all_variant_records method to eager load all variant records on an attachment at once. with_attached_image scope now eager loads variant records if using variant tracking.

  Alex Ghiculescu

• Add metadata value for presence of audio channel in video blobs.

  The metadata attribute of video blobs has a new boolean key named audio that is set to true if the file has an audio channel and false if it doesn't.

  Breno Gazzola

• Adds analyzer for audio files.

  Breno Gazzola

• Respect Active Record's primary_key_type in Active Storage migrations.

  fatkodima

• Allow expires_in for ActiveStorage signed ids.

  aki77

• Allow to purge an attachment when record is not persisted for has_one_attached.

  Jacopo Beschi

• Add a load hook called active_storage_variant_record (providing ActiveStorage::VariantRecord) to allow for overriding aspects of the ActiveStorage::VariantRecord class. This makes ActiveStorage::VariantRecord consistent with ActiveStorage::Blob and ActiveStorage::Attachment that already have load hooks.

  Brendon Muir

• ActiveStorage::PreviewError is raised when a previewer is unable to generate a preview image.

  Alex Robbin

• Add ActiveStorage::Streaming module that can be included in a controller to get access to #send_blob_stream, which wraps the new ActionController::Base#send_stream method to stream a blob from cloud storage:

  class MyPublicBlobsController < ApplicationController
    include ActiveStorage::SetBlob, ActiveStorage::Streaming
  
    def show
      http_cache_forever(public: true) do
        send_blob_stream @blob, disposition: params[:disposition]
      end
    end
  end
  

  DHH

• Add ability to use pre-defined variants.

  class User < ActiveRecord::Base
    has_one_attached :avatar do |attachable|
      attachable.variant :thumb, resize: "100x100"
      attachable.variant :medium, resize: "300x300", monochrome: true
    end
  end
  
  class Gallery < ActiveRecord::Base
    has_many_attached :photos do |attachable|
      attachable.variant :thumb, resize: "100x100"
      attachable.variant :medium, resize: "300x300", monochrome: true
    end
  end
  
  <%= image_tag user.avatar.variant(:thumb) %>
  

  fatkodima

• After setting config.active_storage.resolve_model_to_route = :rails_storage_proxy rails_blob_path and rails_representation_path will generate proxy URLs by default.

  Ali Ismayilov

• Declare ActiveStorage::FixtureSet and ActiveStorage::FixtureSet.blob to improve fixture integration.
