Apologies for the new thread. If i change to what you suggested, the same error apears, but for the @facility ActiveModel::MassAssignmentSecurity::Error in HotelsController#create Can't mass-assign protected attributes: @facility app/controllers/hotels_controller.rb:60:in `new' app/controllers/hotels_controller.rb:60:in `create' As for the code, I even tried to do this on the hotel_controller: def create @hotel = Hotel.new(params[:hotel]).Facility.new(params[:facility]) @hotel.save end But with no success, still mass-assignement error Display log: Started POST "/hotels" for 127.0.0.1 at Mon Apr 16 13:57:18 +0100 2012 Processing by HotelsController#create as HTML Parameters: {"hotel"=>{"@facility"=>{"concierge"=>"0", "room24h"=>"1"}, "rating"=>"2", "recommended"=>"0", "name"=>"kjo"}, "utf8"=>"✓", "commit"=>"Create Hotel", "authenticity_token"=>"buHOvKyQup/ljrFcUej8mzZ01DEJGxYqaUMvUUkyjn8="} Completed 500 Internal Server Error in 0ms ActiveModel::MassAssignmentSecurity::Error (Can't mass-assign protected attributes: @facility): app/controllers/hotels_controller.rb:60:in `new' app/controllers/hotels_controller.rb:60:in `create' Rendered c:/Ruby187/lib/ruby/gems/1.8/gems/actionpack-3.2.3/lib/action_dispatch/middleware/templates/rescues/_trace.erb (1.0ms) Rendered c:/Ruby187/lib/ruby/gems/1.8/gems/actionpack-3.2.3/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (2.0ms) Rendered c:/Ruby187/lib/ruby/gems/1.8/gems/actionpack-3.2.3/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (29.0ms) I thank you for your time to help me. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
