+* `ActiveStorage::Service::AzureStorageService` only handles specifically
+ relevant types of `Azure::Core::Http::HTTPError`. It previously obscured
+ other types of `HTTPError`, which is the azure-storage gem’s catch-all
+ exception class.
+
+ *Cameron Bothner*
+
+* `ActiveStorage::DiskController#show` generates a 404 Not Found response when
+ the requested file is missing from the disk service. It previously raised
+ `Errno::ENOENT`.
+
+ *Cameron Bothner*
+
+* `ActiveStorage::Blob#download` and `ActiveStorage::Blob#open` raise
+ `ActiveStorage::FileNotFoundError` when the corresponding file is missing
+ from the storage service. Services translate service-specific missing object
+ exceptions (e.g. `Google::Cloud::NotFoundError` for the GCS service and
+ `Errno::ENOENT` for the disk service) into
+ `ActiveStorage::FileNotFoundError`.
+
+ *Cameron Bothner*
+
+* Added the `ActiveStorage::SetCurrent` concern for custom Active Storage
+ controllers that can't inherit from `ActiveStorage::BaseController`.
+
+ *George Claghorn*
+
+* Active Storage error classes like `ActiveStorage::IntegrityError` and
+ `ActiveStorage::UnrepresentableError` now inherit from `ActiveStorage::Error`
+ instead of `StandardError`. This permits rescuing `ActiveStorage::Error` to
+ handle all Active Storage errors.
+
+ *Andrei Makarov*, *George Claghorn*
+
+* Uploaded files assigned to a record are persisted to storage when the record
+ is saved instead of immediately.
+
+ In Rails 5.2, the following causes an uploaded file in `params[:avatar]` to
+ be stored:
+
+ ```ruby
+ @user.avatar = params[:avatar]
+ ```
+
+ In Rails 6, the uploaded file is stored when `@user` is successfully saved.
+
+ *George Claghorn*
+
+* Add the ability to reflect on defined attachments using the existing
+ ActiveRecord reflection mechanism.
+
+ *Kevin Deisz*
+
+* Variant arguments of `false` or `nil` will no longer be passed to the
+ processor. For example, the following will not have the monochrome
+ variation applied:
+
+ ```ruby
+ avatar.variant(monochrome: false)
+ ```
+
+ *Jacob Smith*
+
+* Generated attachment getter and setter methods are created
+ within the model's `GeneratedAssociationMethods` module to
+ allow overriding and composition using `super`.
+
+ *Josh Susser*, *Jamon Douglas*
+
+* Add `ActiveStorage::Blob#open`, which downloads a blob to a tempfile on disk
+ and yields the tempfile. Deprecate `ActiveStorage::Downloading`.
+
+ *David Robertson*, *George Claghorn*
+
+* Pass in `identify: false` as an argument when providing a `content_type` for
+ `ActiveStorage::Attached::{One,Many}#attach` to bypass automatic content
+ type inference. For example:
+
+ ```ruby
+ @message.image.attach(
+ io: File.open('/path/to/file'),
+ filename: 'file.pdf',
+ content_type: 'application/pdf',
+ identify: false
+ )
+ ```
+
+ *Ryan Davidson*
+
+* The Google Cloud Storage service properly supports streaming downloads.
+ It now requires version 1.11 or newer of the google-cloud-storage gem.
+
+ *George Claghorn*
+
+* Use the [ImageProcessing](https://github.com/janko-m/image_processing) gem
+ for Active Storage variants, and deprecate the MiniMagick backend.
+
+ This means that variants are now automatically oriented if the original
+ image was rotated. Also, in addition to the existing ImageMagick
+ operations, variants can now use `:resize_to_fit`, `:resize_to_fill`, and
+ other ImageProcessing macros. These are now recommended over raw `:resize`,
+ as they also sharpen the thumbnail after resizing.
+
+ The ImageProcessing gem also comes with a backend implemented on
+ [libvips](http://jcupitt.github.io/libvips/), an alternative to
+ ImageMagick which has significantly better performance than
+ ImageMagick in most cases, both in terms of speed and memory usage. In
+ Active Storage it's now possible to switch to the libvips backend by
+ changing `Rails.application.config.active_storage.variant_processor` to
+ `:vips`.
+
+ *Janko Marohnić*
+
+* Rails 6 requires Ruby 2.4.1 or newer.
+
+ *Jeremy Daer*
+
+

+# Active Storage
+
+Active Storage makes it simple to upload and reference files in cloud services like [Amazon S3](https://aws.amazon.com/s3/), [Google Cloud Storage](https://cloud.google.com/storage/docs/), or [Microsoft Azure Storage](https://azure.microsoft.com/en-us/services/storage/), and attach those files to Active Records. Supports having one main service and mirrors in other services for redundancy. It also provides a disk service for testing or local deployments, but the focus is on cloud storage.
+
+Files can be uploaded from the server to the cloud or directly from the client to the cloud.
+
+Image files can furthermore be transformed using on-demand variants for quality, aspect ratio, size, or any other [MiniMagick](https://github.com/minimagick/minimagick) or [Vips](http://www.rubydoc.info/gems/ruby-vips/Vips/Image) supported transformation.
+
+## Compared to other storage solutions
+
+A key difference to how Active Storage works compared to other attachment solutions in Rails is through the use of built-in [Blob](https://github.com/rails/rails/blob/master/activestorage/app/models/active_storage/blob.rb) and [Attachment](https://github.com/rails/rails/blob/master/activestorage/app/models/active_storage/attachment.rb) models (backed by Active Record). This means existing application models do not need to be modified with additional columns to associate with files. Active Storage uses polymorphic associations via the `Attachment` join model, which then connects to the actual `Blob`.
+
+`Blob` models store attachment metadata (filename, content-type, etc.), and their identifier key in the storage service. Blob models do not store the actual binary data. They are intended to be immutable in spirit. One file, one blob. You can associate the same blob with multiple application models as well. And if you want to do transformations of a given `Blob`, the idea is that you'll simply create a new one, rather than attempt to mutate the existing one (though of course you can delete the previous version later if you don't need it).
+
+## Installation
+
+Run `rails active_storage:install` to copy over active_storage migrations.
+
+## Examples
+
+One attachment:
+
+```ruby
+class User < ApplicationRecord
+ # Associates an attachment and a blob. When the user is destroyed they are
+ # purged by default (models destroyed, and resource files deleted).
+ has_one_attached :avatar
+end
+
+# Attach an avatar to the user.
+user.avatar.attach(io: File.open("/path/to/face.jpg"), filename: "face.jpg", content_type: "image/jpg")
+
+# Does the user have an avatar?
+user.avatar.attached? # => true
+
+# Synchronously destroy the avatar and actual resource files.
+user.avatar.purge
+
+# Destroy the associated models and actual resource files async, via Active Job.
+user.avatar.purge_later
+
+# Does the user have an avatar?
+user.avatar.attached? # => false
+
+# Generate a permanent URL for the blob that points to the application.
+# Upon access, a redirect to the actual service endpoint is returned.
+# This indirection decouples the public URL from the actual one, and
+# allows for example mirroring attachments in different services for
+# high-availability. The redirection has an HTTP expiration of 5 min.
+url_for(user.avatar)
+
+class AvatarsController < ApplicationController
+ def update
+ # params[:avatar] contains a ActionDispatch::Http::UploadedFile object
+ Current.user.avatar.attach(params.require(:avatar))
+ redirect_to Current.user
+ end
+end
+```
+
+Many attachments:
+
+```ruby
+class Message < ApplicationRecord
+ has_many_attached :images
+end
+```
+
+```erb
+<%= form_with model: @message, local: true do |form| %>
+ <%= form.text_field :title, placeholder: "Title" %><br>
+ <%= form.text_area :content %><br><br>
+
+ <%= form.file_field :images, multiple: true %><br>

+
+## Direct uploads
+
+Active Storage, with its included JavaScript library, supports uploading directly from the client to the cloud.
+
+### Direct upload installation
+
+1. Include `activestorage.js` in your application's JavaScript bundle.
+
+ Using the asset pipeline:
+ ```js
+ //= require activestorage
+ ```
+ Using the npm package:
+ ```js
+ import * as ActiveStorage from "activestorage"
+ ActiveStorage.start()
+ ```
+2. Annotate file inputs with the direct upload URL.
+
+ ```ruby
+ <%= form.file_field :attachments, multiple: true, direct_upload: true %>
+ ```
+3. That's it! Uploads begin upon form submission.
+
+### Direct upload JavaScript events
+
+| Event name | Event target | Event data (`event.detail`) | Description |
+| --- | --- | --- | --- |
+| `direct-uploads:start` | `<form>` | None | A form containing files for direct upload fields was submitted. |
+| `direct-upload:initialize` | `<input>` | `{id, file}` | Dispatched for every file after form submission. |
+| `direct-upload:start` | `<input>` | `{id, file}` | A direct upload is starting. |
+| `direct-upload:before-blob-request` | `<input>` | `{id, file, xhr}` | Before making a request to your application for direct upload metadata. |
+| `direct-upload:before-storage-request` | `<input>` | `{id, file, xhr}` | Before making a request to store a file. |
+| `direct-upload:progress` | `<input>` | `{id, file, progress}` | As requests to store files progress. |
+| `direct-upload:error` | `<input>` | `{id, file, error}` | An error occurred. An `alert` will display unless this event is canceled. |
+| `direct-upload:end` | `<input>` | `{id, file}` | A direct upload has ended. |
+| `direct-uploads:end` | `<form>` | None | All direct uploads have ended. |

+# These variants are used to create thumbnails, fixed-size avatars, or any other derivative image from the
+# original.
+#
+# Variants rely on {ImageProcessing}[https://github.com/janko-m/image_processing] gem for the actual transformations
+# of the file, so you must add <tt>gem "image_processing"</tt> to your Gemfile if you wish to use variants. By
+# default, images will be processed with {ImageMagick}[http://imagemagick.org] using the
+# {MiniMagick}[https://github.com/minimagick/minimagick] gem, but you can also switch to the
+# {libvips}[http://jcupitt.github.io/libvips/] processor operated by the {ruby-vips}[https://github.com/jcupitt/ruby-vips]
+# gem).
+#
+# Rails.application.config.active_storage.variant_processor
+# # => :mini_magick
+#
+# Rails.application.config.active_storage.variant_processor = :vips
+# # => :vips
+#
+# Note that to create a variant it's necessary to download the entire blob file from the service. Because of this process,
+# you also want to be considerate about when the variant is actually processed. You shouldn't be processing variants inline
+# in a template, for example. Delay the processing to an on-demand controller, like the one provided in
+# ActiveStorage::RepresentationsController.
+#
+# To refer to such a delayed on-demand variant, simply link to the variant through the resolved route provided
+# by Active Storage like so:
+#
+# <%= image_tag Current.user.avatar.variant(resize_to_fit: [100, 100]) %>
+#
+# This will create a URL for that specific blob with that specific variant, which the ActiveStorage::RepresentationsController
+# can then produce on-demand.
+#
+# When you do want to actually produce the variant needed, call +processed+. This will check that the variant
+# has already been processed and uploaded to the service, and, if so, just return that. Otherwise it will perform
+# the transformations, upload the variant to the service, and return itself again. Example:
+#
+# avatar.variant(resize_to_fit: [100, 100]).processed.service_url
+#
+# This will create and process a variant of the avatar blob that's constrained to a height and width of 100.
+# Then it'll upload said variant to the service according to a derivative key of the blob and the transformations.
+#
+# You can combine any number of ImageMagick/libvips operations into a variant, as well as any macros provided by the
+# ImageProcessing gem (such as +resize_to_fit+):
+#
+# avatar.variant(resize_to_fit: [800, 800], monochrome: true, rotate: "-90")
+#
