How can I combine route declarations (subdomain or token)?

Question

I have a model Model, which can be accessed from different ways: subdomain or token

• http://model1.domain.com
• http://domain.com/j4h7

I have the following routes

resources :model, :constraints => {:model_id => /[a-zA-Z0-9]{4}/} do ... (nested resources...) end resources :model, :constraints => {:subdomain => /.+/} do ... (same as above: nested resources...) end 

Therefore, I have to duplicate all the routes for two cases.

Is it possible to declare it only once?

Answer 1

 def nested_routes get :some_route post :some route resources :some_resources end resources :model, :constraints => {:model_id => /[a-zA-Z0-9]{4}/} do nested_routes end resources :model, :constraints => {:subdomain => /.+/} do nested_routes end
