hotreload error NameError(uninitialized constant Devise::Models::TwoFactorAuthenticatable::AttrEncrypted)

two factor is working perfect, but each time I do a change in my rails app (and server do a hotreload) I start receiving this error:

There was an exception - NameError(uninitialized constant Devise::Models::TwoFactorAuthenticatable::AttrEncrypted)

It only happens when a file is changed, if I restart server everything works normally, any ideaS?

Hi!

When hot reloading your models in dev mode, AttrEncrypted module is removed from constants but it is not reloaded, that's how I understand the issue.

This could be fixed in the gem adding require "attr_encrypted" in the gem ( at the top of devise-two-factor/lib/devise_two_factor/models/two_factor_authenticatable.rb )

In the meantime you can just add the attr_encrypted gem in your app Gemfile it should fix the problem (it did for me)
