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: slots_on_program.rb
    path of file: ./repos/annict/app/graphql/canary/resolvers
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Canary
  module Resolvers
    class SlotsOnProgram < Canary::Resolvers::Base
      include GraphQL::FragmentCache::ObjectHelpers

      def resolve(viewer_untracked: nil, order_by: nil)
        cache_fr
    
      def query_cache_key(context, object)
        [
          Digest::SHA1.hexdigest(context.query.query_string),
          self.class.name,
          context[:viewer]&.id.inspect,
          context[:viewer]&.status_cache_expired_at.to_i,
          context[:viewer]&.record_cache_expired_at.to_i,
          object.updated_at.to_i,
          "1" # キャッシュクリア用の任意の文字列
        ].freeze
      end
