Case insensitive routes in Rails - ruby-on-rails

Question

How can I have a portion of a route Capitalized? For example I have a route scim/v2/user but I'd like it to be scim/v2/User (User capitalized). How can I achieve this while still using resource.
Routes file:
namespace :scim, defaults: { format: :json } do
namespace :v2 do
resource :user, only: [:create, :update, :show]
end
end
When I run $rake routes, I get this:
scim_v2_user POST /scim/v2/user(.:format) scim/v2/users#create {:format=>:json}
GET /scim/v2/user(.:format) scim/v2/users#show {:format=>:json}
PATCH /scim/v2/user(.:format) scim/v2/users#update {:format=>:json}
PUT /scim/v2/user(.:format) scim/v2/users#update {:format=>:json}
I'd like to either have the routes be /scim/v2/User or have them remain the same but have a way of mapping /scim/v2/User to /scim/v2/user.

By default resource wants a direct mapping between the resource name and the controller, but you can simplify use an upper case resource name and manually specify the controller to get around this:
namespace :scim, defaults: { format: :json } do
namespace :v2 do
resource :User, :controller => 'users', only: [:create, :update, :show]
end
end

scim_v2_User GET /scim/v2/User(.:format) scim/v2/users#show {:format=>:json}
PATCH /scim/v2/User(.:format) scim/v2/users#update {:format=>:json}
PUT /scim/v2/User(.:format) scim/v2/users#update {:format=>:json}
POST /scim/v2/User(.:format) scim/v2/users#create {:format=>:json}

I was able to solve this by manually specifying the path and controller. I specified that path should be Users (capitalized). Below is code in my routes file:
namespace :scim, defaults: { format: :json } do
namespace :v2 do
resources :user,
path: "Users",
controller: "users",
only: [:create, :update, :index, :show]
end
end
