Question

If I have two namespaces, and they use the same resources, can I do the following?

namespace :captures, :displays do
  resources :ones
  resources :twos
  resources :threes
  # ...
end

instead of:

namespace :captures do
  resources :ones
  resources :twos
  resources :threes
  # ...
end

namespace :displays do
  resources :ones
  resources :twos
  resources :threes
  # ...
end

or are separate declarations neccessary. I know if they end up have different resources they would have to be separat, but if I can declare the shared ones then I could do something like this:

#shared
namespace :captures, :displays do
  resources :ones
  resources :twos
  resources :threes
  # ...
end

#individual
namespace :captures do
  resources :fours
  resources :fives
  resources :sixes
end
namespace :displays do
  resources :sevens
  resources :eights
  resources :nines
end

Answer 1

Yes separate declaration is necessary while using namespace in routes even if common resources are used.
