Question

重要な更新

application_controller に次の行があります。

authorize_resource if: :html_auth

それを削除すると、すべてがうまくいくようです。authorize_resourcesテストを中断せずにすべてのコントローラーを呼び出す方法はありますか?

元の質問

匿名コントローラーを使用してRSpecでアプリケーションコントローラーをテストしています（これが標準的な方法かどうかはわかりませんが、これがGoogleが私を導いた方法です）。

これは、失敗している 1 つのテストのみを含む完全な RSpec です。

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

そして私のスペックヘルパー：

# 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

バックトレースがコントローラーに当たらないことに気付いたので、関係があるかどうかはわかりません。完全なトレースを取得するため
の RSpec の出力:-b

rspec -b spec/controllers/application_controller_spec.rb 
F

なにが問題ですか？

「s」で終わる「anonymous」を活用しようとすると、Rails が混乱すると思います。これをに追加config/initializers/inflections.rb:

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

docsから、 Rails コンソールで確認できます。

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

これは、rspec 匿名コントローラーが CanCan を呼び出したときに発生しますload_and_authorize_resource(おそらくによって呼び出されるためApplicationController)。

CanCan は、コントローラーの名前からモデルの名前を推測します。@AbeVoelker によって言及された語形変化の問題が原因であるAnonymouと推測されます。AnonymousController

skip_load_and_authorize_resourceエラーを修正するために呼び出します。

controller do
  skip_load_and_authorize_resource

  def index
    raise RuntimeError
  end
end

ruby-on-rails - cancan + rspec = 初期化されていない定数 Anonymou (no s)?
