ruby-on-rails - cancan + rspec = 未初始化常量 Anonymou(无 s)？

Question

重要更新

我的 application_controller 中有以下行:

authorize_resource if: :html_auth

删除它似乎一切正常。有没有办法在不破坏测试的情况下为我的所有 Controller 调用 authorize_resources？

原始问题

我正在使用匿名 Controller 使用 RSpec 测试我的应用程序 Controller (我不确定这是标准做法，但这是 Google 引导我做的)。

这是只有一个测试失败的完整 RSpec:

require "spec_helper"


shared_examples_for "normal errors for html format" do |action, expected_error|
  it "raises the error" do
    expect { get action}.to raise_error(expected_error)
  end
end

describe ApplicationController do
  controller do
    def runtime_error
      raise RuntimeError
    end

    def handable_json_error
      raise ApplicationController::InvalidParams, "model"
    end
  end

  before do
    @routes.draw do
      get 'anonymous/runtime_error'
      get 'anonymous/handable_json_error'
    end
  end

  describe "#handle_exceptions" do
    context "when runtime error happens" do
      describe "with http format" do
        it_behaves_like "normal errors for html format", :runtime_error, RuntimeError
      end
    end
  end
end

还有我的规范助手:

# This file is copied to spec/ when you run 'rails generate rspec:install'
require 'simplecov'
SimpleCov.start 'rails'

ENV["RAILS_ENV"] ||= 'test'

require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'authlogic/test_case'

include Authlogic::TestCase

Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }

RSpec.configure do |config|
  config.include FactoryGirl::Syntax::Methods

  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.use_transactional_fixtures = true

  config.infer_base_class_for_anonymous_controllers = true

  config.order = "random"
end

我注意到回溯甚至没有到达我的 Controller ，所以我不知道是否相关。
使用 -b 的 RSpec 输出，以获得完整的跟踪:

rspec -b spec/controllers/application_controller_spec.rb 
F

我没有在任何地方写过Anonymou。请参阅以下输出:

grep -rin --exclude-dir=log --binary-files=text Anonymou .

怎么了？

我猜 Rails 在尝试变形以“s”结尾的“anonymous”时感到困惑。将此添加到 config/initializers/inflections.rb:

ActiveSupport::Inflector.inflections do |inflect|
  inflect.singular('anonymous', 'anonymous')
end

来自 the docs ，您可以在 Rails 控制台中查看它:

"anonymous".singularize # => "anonymou"
# after adding above to inflections initializer
"anonymous".singularize # => "anonymous"
