我有一个奇怪的情况.我的routes.rb中有这样的代码:

concern :votable do
  post :vote_up, on: :member, controller: :votes
  post :vote_down, on: :member, controller: :votes
end

resources :questions, concerns: [:commentable, :votable], shallow: true do
  resources :answers, concerns: [:commentable, :votable]
end

所以,它给了我帮助,vote_up_question并vote_up_answer通过'post':

vote_up_answer POST   /answers/:id/vote_up(.:format)                 votes#vote_up
vote_down_answer POST   /answers/:id/vote_down(.:format)               votes#vote_down
vote_up_question POST   /questions/:id/vote_up(.:format)               votes#vote_up
vote_down_question POST   /questions/:id/vote_down(.:format)             votes#vote_down

我的votes_controller:

  before_action :load_parent

  def vote_up
    current_user.vote_for(@parent)
    redirect_to :back, notice: "Voted up"
  end

  private

  def load_parent
    resource, id = request.path.split("/")[1, 2]
    @parent = resource.singularize.classify.constantize.find(id)
  end

一切都很完美,但是!我想load_parent用RSpec 测试该方法: …
