Qual é a melhor maneira de alterar dentro params?

realties_controller.rb

class RealtiesController < ApplicationController
  
  before_action :set_realty, :only => [:update]
  
  def update
    @realty.status = 3
    
    if @realty.update_attributes(realty_update_params)
        redirect_to conta_imoveis_path
    end
  end
  
  private
  
  def set_realty
    @realty = Realty.find(params[:id])
  end
  
  def realty_update_params
      params.require(:realty).permit(:title)
  end
  
end
