Rspec 路由规范会导致参数 id 反转失败？

Question

我的 rspec 路由规范返回了不清楚的错误。在预期参数与实际参数中，id 参数处于相反的位置。为什么以及如何解决？

require "spec_helper"

describe GameController do
  describe "routing" do

    game = FactoryGirl.create(:game)

    it "routes to #show" do
      get("/game/1").should route_to("game#show", :id => 1)
    end

  end
end

这会引发错误：

  1) gameController routing routes to #show
     Failure/Error: get("/game/1").should route_to("game#show", :id => 1)
       The recognized options <{"action"=>"show", "controller"=>"game", "id"=>"1"}> did not match <{"id"=>1, "controller"=>"game", "action"=>"show"}>, difference:.
       <{"id"=>1, "controller"=>"game", "action"=>"show"}> expected but was
       <{"action"=>"show", "controller"=>"game", "id"=>"1"}>.
     # ./spec/routing/game_routing_spec.rb:11:in `block (3 levels) in <top (required)>'

Rails 将参数解析为字符串，而不是整数，因此 params[:id] 实际上被分配了 "1" 而不是 1。

尝试期待一个字符串：

get("/game/1").should route_to("game#show", :id => "1")
