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: questions.rb
    path of file: ./repos/retrospring/lib/use_case/data_export
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module UseCase
  module DataExport
    class Questions < UseCase::DataExport::Base
      IGNORED_FIELDS = %i[
      
    
      def files = {
        "questions.json" => json_file!(
          questions: user.questions.map(&method(:collect_question))
        )
      }

      def collect_question(question)
        {}.tap do |h|
          (column_names(::Question) - IGNORED_FIELDS).each do |field|
            h[field] = question[field]
          end
        end
      end
    end
