  • Add support for creating variants of WebP images out of the box.

    Dino Maric

  • Only enqueue analysis jobs for blobs with non-null analyzer classes.

    Gannon McGibbon

  • Previews are created on the same service as the original blob.

    Peter Zhu

  • Remove unused disposition and content_type query parameters for DiskService.

    Peter Zhu

  • Use DiskController for both public and private files.

    DiskController is able to handle multiple services by adding a service_name field in the generated URL in DiskService.

    Peter Zhu

  • Variants are tracked in the database to avoid existence checks in the storage service.

    George Claghorn

  • Deprecate service_url methods in favour of url.

    Deprecate Variant#service_url and Preview#service_url to instead use #url method to be consistent with Blob.

    Peter Zhu

  • Permanent URLs for public storage blobs.

    Services can be configured in config/storage.yml with a new key public: true | false to indicate whether a service holds public blobs or private blobs. Public services will always return a permanent URL.

    Deprecates Blob#service_url in favor of Blob#url.

    Peter Zhu

  • Make services aware of configuration names.

    Gannon McGibbon

  • The Content-Type header is set on image variants when they're uploaded to third-party storage services.

    Kyle Ribordy

  • Allow storage services to be configured per attachment.

    class User < ActiveRecord::Base
  has_one_attached :avatar, service: :s3
end

class Gallery < ActiveRecord::Base
  has_many_attached :photos, service: :s3
end

    Dmitry Tsepelev

  • You can optionally provide a custom blob key when attaching a new file:

    user.avatar.attach key: "avatars/#{user.id}.jpg",
  io: io, content_type: "image/jpeg", filename: "avatar.jpg"

    Active Storage will store the blob's data on the configured service at the provided key.

    George Claghorn

  • Replace Blob.create_after_upload! with Blob.create_and_upload! and deprecate the former.

    create_after_upload! has been removed since it could lead to data corruption by uploading to a key on the storage service which happened to be already taken. Creating the record would then correctly raise a database uniqueness exception but the stored object would already have overwritten another. create_and_upload! swaps the order of operations so that the key gets reserved up-front or the uniqueness error gets raised, before the upload to a key takes place.

    Julik Tarkhanov

  • Set content disposition in direct upload using filename and disposition parameters to ActiveStorage::Service#headers_for_direct_upload.

    Peter Zhu

  • Allow record to be optionally passed to blob finders to make sharding easier.

    Gannon McGibbon

  • Switch from azure-storage gem to azure-storage-blob gem for Azure service.

    Peter Zhu

  • Add config.active_storage.draw_routes to disable Active Storage routes.

    Gannon McGibbon

  • Image analysis is skipped if ImageMagick returns an error.

    ActiveStorage::Analyzer::ImageAnalyzer#metadata would previously raise a MiniMagick::Error, which caused persistent ActiveStorage::AnalyzeJob failures. It now logs the error and returns {}, resulting in no metadata being added to the offending image blob.

    George Claghorn

  • Method calls on singular attachments return nil when no file is attached.

    Previously, assuming the following User model, user.avatar.filename would raise a Module::DelegationError if no avatar was attached:

    class User < ApplicationRecord
  has_one_attached :avatar
end

    They now return nil.

    Matthew Tanous

  • The mirror service supports direct uploads.

    New files are directly uploaded to the primary service. When a directly-uploaded file is attached to a record, a background job is enqueued to copy it to each secondary service.

    Configure the queue used to process mirroring jobs by setting config.active_storage.queues.mirror. The default is :active_storage_mirror.

    George Claghorn

  • The S3 service now permits uploading files larger than 5 gigabytes.

    When uploading a file greater than 100 megabytes in size, the service transparently switches to multipart uploads using a part size computed from the file's total size and S3's part count limit.

    No application changes are necessary to take advantage of this feature. You can customize the default 100 MB multipart upload threshold in your S3 service's configuration:

    production:
  service: s3
  access_key_id: <%= Rails.application.credentials.dig(:aws, :access_key_id) %>
  secret_access_key: <%= Rails.application.credentials.dig(:aws, :secret_access_key) %>
  region: us-east-1
  bucket: my-bucket
  upload:
    multipart_threshold: <%= 250.megabytes %>
