RSpecing:嵌套资源的更新操作

Question

作者有多部作品。作品归作者所有

resources :authors do
  resources :works
end

和RSpec:

it "should redirect to :show" do
  work = FactoryGirl.create(:work)
  controller.stub(:resource) { work }
  work.should_receive(:update_attributes) { true }
  put :update, id: work.id, author_id: work.author.id, work: {}
  response.should redirect_to(admin_author_work_path(work.author, work))
end

和错误:

Expected response to be a redirect to <http://test.host/admin/authors/353/works/166>
but was a redirect to <http://test.host/admin/authors/353/works>

为什么它不重定向到works_controller的:show动作?我错过什么了吗?

我使用继承资源，因此controller.stub(:resource)。
我也注意到assign(:work, work) throws undefined method 'assign' ?它适用于视图，不应该也适用于控制器吗?

Answer 1

就是这样的。

it "should also redirect to :show" do
  author = mock_model(Author)
  work   = mock_model(Work)
  Author.stub(:find) { author }
  author.stub_chain(:works, :find) { work }
  work.should_receive(:update_attributes) { true }
  put :update, id: author.id, author_id: work.id, work: {}
  response.should redirect_to(admin_author_work_path(author, work))
end

所以看起来我不能只存根(:resource)，看起来需要别的东西。尝试使用stub(:parent)也没有运气。看来我不太懂inherited_resources
