Rails routing: Handling multiple nested resources

Question

The following scenario:

    resources :first do
        resources :second do
            resources :third do
                resources :fourth do
                    resources :fifth
                end
            end
        end
        resources :third do
            resources :fourth do
                resources :fifth
            end
        end
    end

    resources :second do
        resources :third do
            resources :fourth do
                resources :fifth
            end
        end
    end

    resources :third do
        resources :fourth do
            resources :fifth
        end
    end

    resources :fourth do
        resources :fifth
    end

As you can see, I am using multiple levels of nested resources. The way I set this up feels pretty repetitive though.

Is there a way to make this more clean?

I don't know what you're trying to accomplish, but I would highly advise you to reconsider your routing scheme. Having 5 levels of nested resources will become extremely cumbersome. I would have a look at Jamis Buck's short paper discussing nested resources. — Mark

@Mark You are right. I just wanted to know if there is a way to prevent duplication in routes theoretically. I am not planning to nest resources four or five levels :) — heroxav

You can use routing concerns to avoid duplication in your routes, e.g.:

concern: :my_concern
  resources :fourth do
    resources :fifth
  end
end

resources :third, concerns: :my_concern
