Rails - find or create - is there a find or build?

I'm currently using:

XXX.find_or_create_by_uuid(XXXX)

Is there a w开发者_C百科ay to do find or build?

Try XXX.find_or_initialize_by_uuid(XXXX)

Since Rails 4 this is XXX.find_or_initialize_by(uuid: XXXX)

In case you want to make your own (Rails 5):

class ApplicationRecord < ActiveRecord::Base

  def self.find_or_build_by hash
    result = all.where(hash)
    result.present? ? result : none.build(hash)
  end
end
