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: relation_factory.rb
    path of file: ./repos/gitlabhq/lib/gitlab/import_export/project/sample
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Gitlab
 
    
          def setup_models
            super

            # Override due date attributes in data hash for Sample Data templates
            # Dates are moved by taking the closest one to average and moving that (and rest around it) to the date of import
            override_date_attributes
          end
