You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: confirmations_controller.rb
    path of file: ./repos/mastodon/app/controllers/api/v1/emails
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

class Api::V1::Emails::ConfirmationsController < Api::BaseController
  before_action -> { authorize_if_got_token! :read, :'read:accounts' }, only: :check
  before_action -> { doorkeeper_authorize! :write, :'write:accounts' }, except: :check

    
  def require_user_owned_by_application!
    render json: { error: 'This method is only available to the application the user originally signed-up with' }, status: 403 unless current_user && current_user.created_by_application_id == doorkeeper_token.application_id
  end

  def require_user_not_confirmed!
    render json: { error: 'This method is only available while the e-mail is awaiting confirmation' }, status: 403 unless !current_user.confirmed? || current_user.unconfirmed_email.present?
  end
end
