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: merge_helpers.rb
    path of file: ./repos/archivesspace/backend/app/lib
    
    the code of the file until where you have to start completion: module MergeHelpers
  def parse_references(request)
    target = JSONModel.parse_reference(request.target['ref'])
    victims = request.victims.map {|victim| JSONModel.parse_reference(victim['ref'])}

    [target, victims]
  end

  def check_repository(target, victims, repo_id)
    repo_uri = JSONModel(:repository).uri_for(repo_id)

    if ([target] + vic
    
  def merge_details_replace_field(target, victim, selections, values)
    selections.each do |path_fix|
      subrec_name = path_fix[0]
      # this is the index of the order the user arranged the subrecs in the form, not the order of the subrecords in the DB.
      ind         = path_fix[1]
      field       = path_fix[2]
      position    = path_fix[3]

      subrec_index = find_subrec_index_in_victim(victim, subrec_name, position)

      target[subrec_name][ind][field] = victim[subrec_name][subrec_index][field]
    end
  end
