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: dialog_field_check_box.rb
    path of file: ./repos/manageiq/app/models
    
    the code of the file until where you have to start completion: class DialogFieldCheckBox < DialogField
  AUTOMATE_VALUE_FIELDS = %w[required read_only visible description].freeze

  def checked?
    value == "t"
  end

  def initial_values
 
    
  def normalize_automate_values(automate_hash)
    self.class::AUTOMATE_VALUE_FIELDS.each do |key|
      send(:"#{key}=", automate_hash[key]) if automate_hash.key?(key)
    end

    return initial_values if automate_hash["value"].blank?

    automate_hash["value"].to_s
  end
