In development enviroment, when using zeitwerk, every change in ruby code needs to restart the server, because zeitwerk isn't loading classes defined in mygem. I have a gem, used by my company that uses rails models. And some of that models are reopened, and we add some methods.

I have the following model in my app.

require_dependency("#{Mygem::Engine.root.join('app','models','identification.rb')}")

class Identification
  include Cacheable
  has_paper_trail

  def some method
  end
end

And the following model in mygem, path of my gem app/models/identification.rb:

class Identification < ApplicationRecord
  self.table_name = 'pub_identification'

  belongs_to :city, foreign_key: 'idcity'
end

But if I change anything in my code, I need restart my server, because model from my gems aren't reopened. I get the error:

undefined local variable or method `has_paper_trail' for Identification:Class

The has_paper_trail method is a method from mygem. And it only works if I restart. Any tips for this?

EDIT:
