As far as I understand your question you have a attachment for both user and message and need a more DRY way of creating routes for this. We can use concerns for this purpose.

concern :attachable do
  resource: :attachment #singular routes
end

resources :users, :messages, concerns: :attachable

I have used singular routes as I assume there is a has_one relationship between attachment and user/message. That is, user has_one attachment or message has_one attachment. If its a has_many relationship, use plural routes ie

resources: :attachments

According to documentation, you'll need:

#config/routes.rb
concern :attachment do
  resources :attachment, only: :index
end

resources :users, :messages, concerns: :attachment
