Salve, Utilizzo Netbeans 6.0 per lo sviluppo con InstantRails 1.7 e ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-mswin32]. Quando faccio partire la mia applicazione sotto netbeans con mongrel mi viene fuori un log contenente diversi errori. Le pagine vengono visualizzate correttamente…sembra. Come posso eliminarli? Sono importanti? Grazie mille. Gli errori sono questi: Rendering E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action\_controller/templates/rescues/layout.rhtml (404 Page Not Found) RenderController: missing default helper path render\_helper ActionController::RoutingError (no route found to match “/render/\_\_utm.js” with {:method=\>:get}): ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action_controller/routing.rb:1292:in ``` `recognize\_path’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action_controller/routing.rb:1282:in ``` `recognize’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/rails-1.2.3/lib/dispatcher.rb:40:in ``` `dispatch’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel/rails.rb:78:in ``` `process’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel/rails.rb:76:in ``` `synchronize’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel/rails.rb:76:in ``` `process’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel.rb:618:in ``` `process\_client’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel.rb:617:in ``` `each’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel.rb:617:in ``` `process\_client’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel.rb:736:in ``` `run’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel.rb:736:in ``` `initialize’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel.rb:736:in ``` `new’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel.rb:736:in ``` `run’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel.rb:720:in ``` `initialize’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel.rb:720:in ``` `new’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel.rb:720:in ``` `run’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel/configurator.rb:271:in ``` `run’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel/configurator.rb:270:in ``` `each’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel/configurator.rb:270:in ``` `run’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/bin/mongrel_rails:127:in ``` `run’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/lib/mongrel/command.rb:211:in ``` `run’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.0.1-mswin32/bin/mongrel_rails:243 E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/dependencies.rb:488:in ``` `load’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/dependencies.rb:488:in ``` `load’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/dependencies.rb:342:in ``` `new\_constants\_in’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/dependencies.rb:488:in ``` `load’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/rails-1.2.3/lib/commands/servers/mongrel.rb:60 E:/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in ``` `gem\_original\_require’ ``` E:/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in ``` `require’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/dependencies.rb:495:in ``` `require’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/dependencies.rb:342:in ``` `new\_constants\_in’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/dependencies.rb:495:in ``` `require’ ``` E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/rails-1.2.3/lib/commands/server.rb:39 E:/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in ``` `gem\_original\_require’ ``` E:/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in ``` `require’ ``` script/server:3 ``` ---

Manca il file apps/helpers/render\_helper.rb Magari hai creato il controller a mano e non con scripts/generate controller che crea tutti i file necessari. Niente di grave, basta che crei tu il file con dentro solo module RenderHelper end Nota comunque che l’applicazione dovrebbe funzionare lo stesso anche senza l’helper. > ActionController::RoutingError (no route found to match > “/render/\_\_utm.js” with {:method=\>:get}): Questo invece è un po’ più strano. Guardando l’url sembra che render sia il nome di un controller e \_utm.js un partial (nota i tuoi due underscore). La combinazione mi insospettisce dato che di solito si usa render :partial =\> “\_utm.js” ma senza l’\_ visto che ce lo mette Rails. Non vorrei allora che ci sia stato qualche fraintendimento sull’uso di questo metodo. Di più non ti so dire senza vedere il tuo codice. Paolo ---
