Rails: benefits of URL modification vs Namespace?

Many people talk about the namespace as a way to change the URL that leads to their controller with a prefix (for example: / admin / movies instead of / movies)

URL path change

The official white paper explains that if we want to change the URL that leads to our controller with a prefix, we just need to change our resource in config / route.rb.

From this:

  resources :movies

:

  resources :movies, :path => "/admin/movies"

Namespace Injection

After many googsearches, I wonder why so many people like to have a namespace and what are the advantages of a namespace, and not just changing the path of the URL leading to a specific controller in the router file: myapp / config / route.rb
