Rspec:2 级嵌套资源的控制器规范

问题描述

我的路线.rb

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

在为评论编写控制器规范时:

While writing controller specs for Comments:

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 

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

Any idea how to give the page and article reference to get :index ?? if I give : get :index, :article_id => @article.id
Error I get is below:

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

推荐答案

你的路由至少需要两个 ID:评论的父文章和文章的父页面.

Your route requires at least two IDs: the comment's parent article, and the article's parent page.

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 才能使此路由正常工作:

All parent IDs must be provided for this route to work:

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
