Rails Devise+Cancan how to redirect a specific user role to a specific namespace?

Question

Ruby on Rails

Hello
There are 4 user roles. I make a separate namespace for each role.
Tell me where in the application and how, after determining the user's role, redirect him to a specific namespace. Moreover, it is desirable that the namespace is not reflected in the address bar in any way.
Those. Ideally, after authorization, the user opens, for example, the root_path is already his namespace. And in the address line there is nothing like server.name/namespace , but just server.name Is it possible to do this? Or does the definition of namespace always come from the address bar?

Answer 1

I somehow popped up in production such a thing.
Suppose there are 2 routes:

get '/home' => ''
get '/:id' => ''

If the first one threw an exception, then the second one was rendered
. Unfortunately, when I tried to reproduce it, it didn’t work.
Maybe it’s a rails 4.0 bug
PS: if you find the answer, write it down here, I’m also interested
