Ciao a tutti, stavo provando ad usare ActionMailer, ma anche dopo aver configurato tutto correttamente, eseguo un controller di test semplice: class TestController \< ApplicationController def ship\_order order = Order.find(6) email = OrderMailer.create\_confirm(order) OrderMailer.deliver(email) render(:text =\> ‘OK!’) end end E ottengo sempre questo errore: undefined method `delete’ for #Order:0x3458a00 Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active\_record/base.rb:1860:in `method_missing' /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action_view/template_error.rb:87:in`remove\_deprecated\_assigns!’ /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action\_view/template\_error.rb:86:in `each' /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action_view/template_error.rb:86:in`remove\_deprecated\_assigns!’ /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action\_view/template\_error.rb:14:in `initialize' /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action_view/base.rb:266:in`new’ /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action\_view/base.rb:266:in `render_file' /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action_view/base.rb:283:in`render’ /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/actionmailer-1.3.3/lib/action\_mailer/base.rb:481:in `render' /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/actionmailer-1.3.3/lib/action_mailer/base.rb:476:in`render\_message’ /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/actionmailer-1.3.3/lib/action\_mailer/base.rb:424:in `create!' /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/actionmailer-1.3.3/lib/action_mailer/base.rb:385:in`initialize’ /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/actionmailer-1.3.3/lib/action\_mailer/base.rb:332:in `new' /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/lib/ruby/gems/1.8/gems/actionmailer-1.3.3/lib/action_mailer/base.rb:332:in`method\_missing’ #{RAILS\_ROOT}/app/controllers/test\_controller.rb:5:in `ship_order' /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/bin/mongrel_rails:16:in`load’ /Applications/Locomotive2/Bundles/standardRailsMar2007.locobundle/i386/bin/mongrel\_rails:16 Non ho proprio idea di cosa fare in questo caso, perchè non credo sia un mio problema di configurazione… Sapete aiutarmi!?

Non la faccio mai! Eseguo solo quell’azione che ho messo nel primo post… per la configurazione ho seguito la guida “HowToSendEmailsWithActionMailer” e credo sia giusta… ---

Il delete viene richiamato in ActionView::TemplateError ``` def remove_deprecated_assigns! ActionController::Base::DEPRECATED_INSTANCE_VARIABLES.each do ``` |ivar| @assigns.delete(ivar) end end Sembra quindi che @assigns sia valorizzata in modo incorretto. Altro non so… ---

Praticamente prendevo spunto sia dal howto che dal libro “Sviluppare applicazione web con Rails”, dove forse c’è una configurazione di actionmailer un po vecchia. In pratica non passavo un hash al metodo body, ma solo una variabile d’istanza … ora sembra funzionare tutto. Grazie mille! Ciao! ---

Dear Niko, I have encountered the identical problem, but I don’t understand how you were able to solve it. How exactly did you fix it, do you remember? Thank you so much.
