default_url_option prevalences

[daniel2d2art]

default_url_options provided method should override :defaults option on routes entry
and not vice versa.

Thank you for your interest in rails.
Could you create a sample app reproducing the use case you're describing?

Just this code:

routes.rb

  scope '/myscope(/:alternative_param)', :defaults => {:alternative_param => nil}
    namespace :mynamespace do
      resources :foos
    end
  end

foos_controller.rb

  def default_url_options
    {:alternative_param=>params[:alternative_param]}
  en

I say, default params set on "controller#default_url_options" must override the "routes :default" assigment, but works on the contrary routes override the provide callback functionality to defalut_ulr_option.

I would say that Controller#default_url_options should override default_url_options in routes.rb but not override a route's defaults because it's a global setting whereas a route's defaults are specific. There are plenty of ways you can achieve what you want by overriding the url helper directly either in a helper or directly on the Rails.application.routes.url_helpers module
