Overview

‘Tapioca::Compilers::Dsl::ActiveStorage` decorates RBI files for subclasses of `ActiveRecord::Base` that declare [one](edgeguides.rubyonrails.org/active_storage_overview.html#has-one-attached) or [many](edgeguides.rubyonrails.org/active_storage_overview.html#has-many-attached) attachments.

For example, with the following ‘ActiveRecord::Base` subclass:

~~~rb class Post < ApplicationRecord

has_one_attached :photo
has_many_attached :blogs

end ~~~

this generator will produce the RBI file ‘post.rbi` with the following content:

~~~rbi # typed: strong

class Post

sig { returns(ActiveStorage::Attached::Many) }
def blogs; end

sig { params(attachable: T.untyped).returns(T.untyped) }
def blogs=(attachable); end

sig { returns(ActiveStorage::Attached::One) }
def photo; end

sig { params(attachable: T.untyped).returns(T.untyped) }
def photo=(attachable); end

end ~~~
