Raw Normal View History

* 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:
```ruby
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.
```ruby
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
*Sean Doyle*
