form_for and scopes, rails 3

Question

I have a problem due to scopes and the form_for helper in rails 3. The routes - file looks like this:

scope \"(/:tab)\" do
  resources :article
end
         


        

Answer 1

I have found this to be a really irritating problem and have gotten around this for now with the following monkey patch. Generic like this, it's a little bid off as you're simply passing the entire bag of parameters to polymorphic_url which is what form_for uses under the hood to guess the route. A more concise approach would be to merge just the scope value.

My solution:

module ActionDispatch
  module Routing
    module PolymorphicRoutes
      def polymorphic_path(record_or_hash_or_array, options = {})
        begin
            polymorphic_url(record_or_hash_or_array, options.merge(:routing_type => :path))
        rescue Exception => e
            polymorphic_url(record_or_hash_or_array, options.merge(:routing_type => :path).merge(params.reject{|k,v| ["controller", "action"].include? k.to_s}))
        end
      end
    end
  end
end
