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: configuration.rb
    path of file: ./repos/open-build-service/src/api/app/models
    
    the code of the file until where you have to start completion: # The OBS instance configuration
class Configuration < ApplicationRecord
  after_save :delayed_write_to_backend

  include CanRenderModel
  include Configuration
    
  def update_from_options_yml
    # strip the not set ones
    attribs = ::Configuration::OPTIONS_YML.clone
    attribs.each_key do |k|
      if attribs[k].nil?
        attribs.delete(k)
        next
      end

      attribs[k] = ::Configuration.map_value(k, attribs[k])
    end
