我有这种奇怪的测试失败.

我的routes.rb

resources :my_reports,only: [:index] do
  collection do
    get "/report/:filename",to: :show,prefix: "pri/excl/rep",as: :show
  end
end

我的规范已经在Rails 3.2.x中传递,现在在更新到4.0.4后失败了

describe MyReportsController do
  describe "#show" do
    def make_request
      get :show,prefix: 'some/place',filename: 'foo',format: 'doc'
    end

    it "makes a simple request" do
      make_request
    end
  end
end

我收到以下错误

Failure/Error: get :show,format: 'doc'
     ActionController::UrlGenerationError:
       No route matches {:action=>"show",:controller=>"my_reports",:filename=>"foo",:format=>"doc",:prefix=>"some/place"}

我被困在这一点,欢迎提示.我正在使用rspec和rspec-rails版本2.14.1.
