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: ASModel_transfers.rb
    path of file: ./repos/archivesspace/backend/app/model
    
    the code of the file until where you have to start completion: module ASModel
  # Code for moving records between repositories
  module RepositoryTransfers

    def self.included(base)
      base.extend(ClassMethods)
    end


    def transfer_to_repository(target_repository, transfer_group = [])
      if self.class.columns.include?(:repo_id)

        source_repository = Repository[self.repo_id]

        # Do the update in the cheapest way possible (bypassing save hooks, etc.)
        self.class.filter(id: self.id).update(repo_id: target_repository.id,
            
    
    def transfer_to_repository(target_repository, transfer_group = [])
      if self.class.columns.include?(:repo_id)

        source_repository = Repository[self.repo_id]

        # Do the update in the cheapest way possible (bypassing save hooks, etc.)
        self.class.filter(id: self.id).update(repo_id: target_repository.id,
                                                 system_mtime: Time.now)

        # Mark the old URI as deleted (if we can locate the source repo)
        if source_repository
          RequestContext.open(repo_id: source_repository.id) do
            Tombstone.create(uri: self.uri)
            DB.after_commit do
              RealtimeIndexing.record_delete(self.uri)
            end
          end
        end
