NoMethodError - undefined method `timestamp_sort_order' for Paper trail issue after upgrading Rails 4.2

Question

I used paper_trail to tracking transnational changes when I migrated rails 3.2 to rails 4.2, have got below issue:

NoMethodError - undefined method `timestamp_sort_order' for

Answer 1

got this on rails 6.0.0beta3 because I patched papertrail and forgot to add PaperTrail::VersionConcern, e.g.:

module PaperTrail
  class Version < ::ActiveRecord::Base
    include PaperTrail::VersionConcern
  end
end

---

PaperTrail::Rails::Engine.eager_load! did not fix it for me

looking at the source code it's calling it directly on an ActiveRecord::Base model, it's defined on PaperTrail::VersionConcern.

Answer 2

I fixed this by adding below line in intializer paper_trail.rb file

PaperTrail::Rails::Engine.eager_load!

See my final intializers/paper_trail.rb file

PaperTrail.config.track_associations = false

PaperTrail::Rails::Engine.eager_load!

module PaperTrail

  class Version < ActiveRecord::Base
    .....
  end

end

Problem resolved....

Have updated my answer added below line extra using it with rails 5.2

PaperTrail.config.track_associations = false
