How to have one resource in routes for namespace a

问题:

I am making a custom admin panel in a namespace "admin".

I have resources "courses" within that namespace.

But I would also like a route to "courses" that is not in that namespace:

eg: BOTH localhost:3000/admin/courses AND localhost:3000/courses

It's OK if this requires different controllers.

My concern is that its not really DRY if i have both resources for the same route.

namespace admin do
   resources :courses
end

and just

resources :courses

Is there a way to have one resource be shared between namespace and without namespace, or is the example above the way to go?

回答1:

Oh wait ! There's also the possibility to use concerns !

concern :shared_actions do
   resources :courses
   resources :something_else
end


namespace :admin do
   concerns :shared_actions
end
concerns :shared_actions # Will add it to the root namespace ^^

EDIT : apparently this is what this guy also tried to do :D

I'm not really sure I understand what you mean, but

namespace :something is actually a shorthand for scope :something, module: :something, as: :something

• scope :something will add /something/ as a URL prefix
• scope module: :something will add /something as a controller prefix (controllers will be fetched under controlelrs/something/the_controller.rb
• scope as: :something will add the something as a prefix for path helpers

Now it's totally fine to have both in your routes

resources :courses
# Will generate "/courses/", "/courses/new", "/courses/1/edit", ...
# And will point to `controllers/courses_controller.rb`

namespace :admin do
  resources :courses
end
# Will generate "/admin/courses/", "/admin/courses/new", "/admin/courses/1/edit", ...
# And will point to `controllers/admin/courses_controller.rb`

Does this answer your question ?
