undefined method `authenticate_user!' when want to version my api

[Mirigan]

Hello !
I have a huge problem, to day I wanted to versioning my api and my auth routes so I did this

namespace :api do
    namespace :v1 do
      mount_devise_token_auth_for 'User', as: 'v1', at: 'auth', controllers: {
        registrations:  'api/v1/user/registrations',
        passwords:      'api/v1/user/passwords',
        sessions:       'api/v1/user/sessions'
      }
    end

    namespace :v2 do
      mount_devise_token_auth_for 'User', as: 'v2', at: 'auth', controllers: {
        registrations:  'api/v2/user/registrations',
        passwords:      'api/v2/user/passwords',
        sessions:       'api/v2/user/sessions'
      }
    end
  end

but now I have an error undefined method 'authenticate_user!' and don't find solution.
Can someone have any idea ?

As a quick work-around you can copy mount_devise_token_auth_for code to top, out of namespaces, since both versions will use the same credentials. Then you can have multiple mount_devise_token_auth_for entries with duplicate endpoints.

if you want to limit your routes to minimum, then you should use authenticate_v1_user! in your v1 controller and vice versa.

Also amitfriedman12 wrote in this issue using devise helper to your controllers might help.

include Devise::Controllers::Helpers

@gundogantekant thank you for your workaround! Closing for now.
