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

Question

在我尝试从4.1.8升级到rails 4.2.0.rc1时,运行服务器时出现以下错误:

from bin/rails:4:in `<main>'

在我的application.rb文件中,我有以下内容:

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

有关如何排除故障的任何建议？

Answer 1

他们已经解决了这个问题:https://github.com/josevalim/inherited_resources/commit/6d034d913bfd9b53ea2e5b31c4056578a1b170a4.我正在使用带有rails 4.2.1的最新gem发布,它运行正常.

对于遇到此问题的任何人,请尝试bundle update inherited_resources.

老答案:

您必须使用rails 4.2的特定分支:

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

Answer 2

我在这里并不完全确定,但我确实知道它action_controller/metal/responder.rb已从4.2中的rails中删除,几乎直接复制到respondersgem中action_controller/responder.rb.您可以尝试添加gem 'responders', '~> 2.0'到Gemfile以查看是否修复了它.

FWIW:

• 响应者2.x:responders/lib/action_controller/responder.rb
• 从Rails 4.1.8:rails/actionpack/lib/action_controller/metal/responder.rb
• metal/Rails 4.2.2.rc2中的目录:rails/actionpack/lib/action_controller/metal /(注意没有更多responders.rb.
