I have a custom form builder for my application: # file location: /lib/ruby/app_form_builder.rb
class ActionView::Helpers::AppFormBuilder < ActionView::Helpers::FormBuilder include ActionView::Helpers::TagHelper include ActionView::Context def foo 'bar' end end I am requiring it in an initializer: require "#{Rails.root}/lib/ruby/app_form_builder.rb" ActionView::Base.default_form_builder = ActionView::Helpers::AppFormBuilder This works, but I have to restart the server on every change. I was reading the Constant Guide <http://edgeguides.rubyonrails.org/autoloading_and_reloading_constants.html>, but didn't find the right way to made this file to be automaticaly reloaded. I tried to put this in /app/helpers forlder and making it default in application.rb, but I got "unitialized constant" error. Also, I would like to know if Rails can reload code that modify native Ruby classes: class String def do_something 'something' end end -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
