/ app / lib / classes / nino_nino.rb начинается так:

    require 'classes/global/String'
    require 'classes/zip'
    require 'tempfile'

        module NinoNino
            class NinoNinoController < ApplicationController

                def crea_certificados(par)

                    session = {}
                    session["group_id"] = par["group_id"]

                    @anio = par["anio"].to_i
                    @mes = par["mes"].to_i
                    @municipio = par["municipio"]
                    @dias_mes = (JSON.parse par["dias_mes"]).collect {|e| e["value"]}
                    @genera_nino_nino = (par["genera_nino_nino"] == "true")
                    @genera_resumen = (par["genera_resumen"] == "true")
                    job_id = par["job_id"]

                    @format = par["format"]
                    (...)

классы / глобальные / строка:

class String
    def last_n_chars(len)
        self[-len..-1] || self
    end
end
