undefined method `authenticate_user!' when User class nested in module

[WojciechKo]

Hey!
I've seen a few of the issues that describes following error and gives us a way to deal with it when mount_devise_token_auth_for is nested inside of namespace in Rails routing. #182

*** NoMethodError Exception: undefined method `authenticate_user!' for"

I found out that when you nest your model inside of a module, the helper-methods names changes as well.

module Models
  class User < ApplicationRecord
    include DeviseTokenAuth::Concerns::User
  end
end

Rails.application.routes.draw do
  mount_devise_token_auth_for 'Models::User', at: 'auth'
end

class ApplicationController < ActionController::API
  include DeviseTokenAuth::Concerns::SetUserByToken
  before_action :authenticate_models_user!
end

Do you have any proposition how to get authenticate_user in given example without method aliasing?

@WojciechKo and how can we find the class? User itself doesn't exist in your codebase, and I don't think method aliasing for this case is bad. Sorry about that!

[WojciechKo]

Probably we can't. Was hoping for some kind of configuration option or something.
Anyway, thanks for clarification and for this awesome gem!

Yeah sorry, we have tons of configurations and we cannot contemplate each case (that's the problem with engines).
