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: submission_pool.rb
    path of file: ./repos/sequencescape/app/models
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

    
      def self.included(base)
        base.class_eval do
          has_many :submission_pools, -> { distinct }, through: :well_requests_as_target

          def submission_pools
            SubmissionPool.for_plate(self)
          end
        end
      end
