mounting engine in namespace

I am testing an engine which normally is mounted at /

NotifyMe::Application.routes.draw do mount_opro_oauth :controllers => {:oauth_client_apps => ‘oauth/client_apps’}

I am trying to mount it inside my existing backoffice namespace, is it possible or not advisable

namespace :backoffice do match ‘/’, to: ‘dashboards#show’ resource :dashboards, :only => :show

mounting it at root give me urls like :


but as it’s a backoffice process, I would like to have urls like:


I tried to move the mount line inside the namespace, but then I got issues with the engine routes…

I thought /backoffice would have been added automatically

thanks for your feedback
