How to require_relative helper methods from a seed file?

[cirosantilli]

I want to share some helper methods across multiple seed files:

db/fixtures/development/01.rb
db/fixtures/development/02.rb
db/fixtures/development/helper.rb

the problem is that require_relative does not work because the seed files are run with eval: http://stackoverflow.com/questions/16421669/ruby-require-relative-gives-loaderror-cannot-infer-basepath

Is there a way to require using relative paths from the seed files? The best I could come up with was using Rails.root.join, but that is not very DRY.
