RSpecing：嵌套資源的更新操作

Question

作者有很多作品。作品屬於作者。

resources :authors do 
    resources :works 
end 

而RSpec的：

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 

和錯誤：

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> 

爲什麼不能重定向到works_controller的：表演動作？我錯過了什麼嗎？

我正在使用inherited-resources，因此controller.stub（：resource）。我也注意到assign(:work, work) throws undefined method 'assign'？它在視圖中工作，它不應該也適用於控制器嗎？

這就是訣竅。

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 

所以看來我不能只存根（：資源），看起來像別的東西是需要的。試圖與存根（：父母）也沒有運氣。看起來我不太瞭解inherited_resources這麼好。

歡迎評論。
