split and organize seeds.rb [rails]

seeds.rb

# store all seeds inside the folder db/seeds
# files are sorted alphabetically before loading them, so we can make sure the files are processed in order 
# choose the filenames wisely, e.g. something like 0100_operators.rb, 0200_companies.rb, 0300_products.rb ...)

Dir[File.join(Rails.root, 'db', 'seeds', '*.rb')].sort.each { |seed| load seed }
