I have a nested resource hotel\_user and i wish to have hotel\_users\_controller under hotel namespace. I want to use restful authentication here and I want hotel\_users\_controller, sessions\_controller in hotel directory like hotel/hotel\_users\_controller and hotel/sessions\_controller. I tried with the following command in terminal and it failed. script/generate authenticated hotel\_user hotel/session and it failed with the error The name ‘AuthenticatedSystem’ is either already used in your application or reserved by Ruby on Rails.Please choose an alternative and run this generator again. The authenticated\_system.rb file exists for some other resource under lib directory and not for hotel\_user. the generator is seeing it and fails the generation of files. what can I do? please help ---

It was OK when better alternatives didn’t exist, but they do now. Use Authlogic or something else reasonable. ## Best, Marnen Laibow-Koser [http://www.marnen.org](http://www.marnen.org) removed\_email\_address@domain.invalid ---

Besides your choice of authentication systems, it also sounds to me like you may be confusing authentication and authorization. If you want to add some sort of role based authorization then take a look at one of the authorization gems/plugins such as CanCan. > **[GitHub - ryanb/cancan: Authorization Gem for Ruby on Rails.](https://github.com/ryanb/cancan)** > > Authorization Gem for Ruby on Rails.

I will use authlogic. I have just entered rails horizon and thank you so much for the recommendation.
