Rails 4.2.0.rc1 upgrade <module:InheritedResources>': uninitialized constant ActionController::Responder (NameError)

Question

In my attempt to upgrade to rails 4.2.0.rc1 from 4.1.8 I get the following error when running the server:

In my application.rb file I have the following:

require File.expand_path('../boot', __FILE__)

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(:default, Rails.env)

module Rentlit
  class Application < Rails::Application

    config.generators.helper = false
    config.generators.assets = false
    config.generators.view_specs = false
  end
end

Any suggestions on how to troubleshoot?

Answer 1

They already solved it: https://github.com/josevalim/inherited_resources/commit/6d034d913bfd9b53ea2e5b31c4056578a1b170a4 . I'm using the latest gem release with rails 4.2.1 and it's working ok.

For anyone experiencing the problem, try bundle update inherited_resources .

Old answer:

You have to use the specific branch for rails 4.2:

gem 'inherited_resources', github: 'josevalim/inherited_resources', branch: 'rails-4-2'

Answer 2

I'm not entirely sure here, but I do know that action_controller/metal/responder.rb was removed from rails in 4.2 and almost directly copied to the responders gem's action_controller/responder.rb . You might try adding gem 'responders', '~> 2.0' to your Gemfile to see if that fixes it.

FWIW:

• responders 2.x: responders/lib/action_controller/responder.rb
• From Rails 4.1.8: rails/actionpack/lib/action_controller/metal/responder.rb
• The metal/ dir in Rails 4.2.2.rc2: rails/actionpack/lib/action_controller/metal/ (notice there's no more responders.rb .

Answer 3

至于现在，只是跑

bundle update inherited_resources
