Defined in:

Overview

‘Tapioca::Dsl::Compilers::ActiveRecordEnum` decorates RBI files for subclasses of `ActiveRecord::Base` which declare [`enum` fields](api.rubyonrails.org/classes/ActiveRecord/Enum.html).

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

~~~rb class Post < ApplicationRecord

enum title_type: %i(book all web), _suffix: :title

end ~~~

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

~~~rbi # post.rbi # typed: true class Post

include EnumMethodsModule

module EnumMethodsModule
  sig { void }
  def all_title!; end

  sig { returns(T::Boolean) }
  def all_title?; end

  sig { returns(T::Hash[T.any(String, Symbol), Integer]) }
  def self.title_types; end

  sig { void }
  def book_title!; end

  sig { returns(T::Boolean) }
  def book_title?; end

  sig { void }
  def web_title!; end

  sig { returns(T::Boolean) }
  def web_title?; end
end

end ~~~
