ruby-on-rails - Rspec：2 级嵌套资源的控制器规范

Question

我的路线.rb

  namespace :magazine do
   resources :pages do
     resources :articles do
       resources :comments
     end
   end
  end

在为 Comments 编写控制器规范时：

describe "GET 'index'" do
    before(:each) do
     @user = FactoryGirl.create(:user)
     @page = FactoryGirl.build(:page)
     @page.creator = @user
     @page.save
     @article = FactoryGirl.create(:article)
     @comment_attributes = FactoryGirl.attributes_for(:comment, :article_id => @article )
   end
it "populates an array of materials" do
  get :index, ??
  #response.should be_success
  assigns(:comments)
end

it "renders the :index view" do
  get :index, ?? 
  response.should render_template("index")
end

end 

知道如何提供页面和文章参考以获取 :index 吗？如果我给 :get :index, :article_id => @article.id
我得到的错误如下：

 Failure/Error: get :index, :article_id => @article.id
 ActionController::RoutingError:
   No route matches {:article_id =>"3", :controller=>"magazine/comments"}

Answer 1

您的路由至少需要两个 ID：评论的父文章和文章的父页面。

namespace :magazine do
  resources :pages do
    resources :articles do
      resources :comments
    end
  end
end

# => /magazine/pages/:page_id/articles/:article_id/comments

必须提供所有父 ID才能使此路由生效：

it "renders the :index view" do
  get :index, {:page_id => @page.id, :article_id => @article.id}
  # [UPDATE] As of Rails 5, this becomes:
  # get :index, params: {:page_id => @page.id, :article_id => @article.id}
  response.should render_template("index")
end

Answer 2

在 Rails 5 中，params API 发生了变化：

get :index, params: { page_id: @page.id, article_id: @article.id }
