我有一个类似于下面的Rake脚本,但我想知道是否有更有效的方法来执行此操作,而不必删除数据库,运行所有迁移,重新设置数据库,然后添加示例数据？

namespace :db do

  desc 'Fill database with sample data'
  task populate: :environment do
    purge_database
    create_researchers
    create_organisations
    add_survey_groups_to_organisations
    add_members_to_survey_groups
    create_survey_responses_for_members

  end
end


    def purge_database
      puts 'about to drop and recreate database'
      system('rake db:drop')
      puts 'database dropped'
      system('rake db:create')
      system('rake db:migrate')
      system('rake db:seed')
      puts 'Database recreated...'
    end

    def create_researchers
      10.times do
        researcher = User.new
        researcher.email = Faker::Internet.email
        researcher.save!
      end
    end
