Module ActiveModel::Naming
In: lib/active_model/naming.rb

Active Model Naming

Creates a model_name method on your object.

To implement, just extend ActiveModel::Naming in your object:

  class BookCover
    extend ActiveModel::Naming
  end

  BookCover.model_name        # => "BookCover"
  BookCover.model_name.human  # => "Book cover"

  BookCover.model_name.i18n_key              # => "book_cover"
  BookModule::BookCover.model_name.i18n_key  # => "book_module.book_cover"

Providing the functionality that ActiveModel::Naming provides in your object is required to pass the Active Model Lint test. So either extending the provided method below, or rolling your own is required..
