使用 RSpec 测试嵌套资源
我正在尝试为 Rails 中的嵌套资源创建测试。相关的路由定义是：
resources :communities do
resources :contents, :type => 'Content'
end
使用RSpec和factory_girl，我试图开始使用例如进行测试
describe ContentsController do
it 'should display a content item under a community' do
content = FactoryGirl.create(:content)
get :show, :community_id => content.community.id, :id => content.id
end
end
这些请求总是导致
Failure/Error: get :show, :community_id => content.community.id, :id => content.id
ActionController::RoutingError:
No route matches {:community_id=>BSON::ObjectId('4e7773c6ac54c3d1ad000002'),
:id=>BSON::ObjectId('4e7773c6ac54c3d1ad000001'), :controller=>"contents",
:action=>"show"}
在我的一生中我找不到一种方法来使用RSpec指定到嵌套资源的路由。我在这里做的是根本错误的事情吗？
更新：耙子路线的相关部分是：
community_contents GET /communities/:community_id/contents(.:format) {:action=>"index", :controller=>"contents"}
POST /communities/:community_id/contents(.:format) {:action=>"create", :controller=>"contents"}
new_community_content GET /communities/:community_id/contents/new(.:format) {:action=>"new", :controller=>"contents"}
edit_community_content GET /communities/:community_id/contents/:id/edit(.:format) {:action=>"edit", :controller=>"contents"}
community_content GET /communities/:community_id/contents/:id(.:format) {:action=>"show", :controller=>"contents"}
PUT /communities/:community_id/contents/:id(.:format) {:action=>"update", :controller=>"contents"}
DELETE /communities/:community_id/contents/:id(.:format) {:action=>"destroy", :controller=>"contents"}
I am trying to create tests for nested resources in Rails. The relevant route definition is:
resources :communities do
resources :contents, :type => 'Content'
end
Using RSpec and factory_girl, I am trying to get started with testing with e.g.
describe ContentsController do
it 'should display a content item under a community' do
content = FactoryGirl.create(:content)
get :show, :community_id => content.community.id, :id => content.id
end
end
These requests always result in
Failure/Error: get :show, :community_id => content.community.id, :id => content.id
ActionController::RoutingError:
No route matches {:community_id=>BSON::ObjectId('4e7773c6ac54c3d1ad000002'),
:id=>BSON::ObjectId('4e7773c6ac54c3d1ad000001'), :controller=>"contents",
:action=>"show"}
For the life of me I cannot find a way to specify a route to a nested resource with RSpec. Am I doing something fundamentally wrong here?
Update: The relevant part of rake routes is:
community_contents GET /communities/:community_id/contents(.:format) {:action=>"index", :controller=>"contents"}
POST /communities/:community_id/contents(.:format) {:action=>"create", :controller=>"contents"}
new_community_content GET /communities/:community_id/contents/new(.:format) {:action=>"new", :controller=>"contents"}
edit_community_content GET /communities/:community_id/contents/:id/edit(.:format) {:action=>"edit", :controller=>"contents"}
community_content GET /communities/:community_id/contents/:id(.:format) {:action=>"show", :controller=>"contents"}
PUT /communities/:community_id/contents/:id(.:format) {:action=>"update", :controller=>"contents"}
DELETE /communities/:community_id/contents/:id(.:format) {:action=>"destroy", :controller=>"contents"}

我看到您将 content.community.id 作为 :community_id 传递，并且该对象看起来像用 BSON::ObjectId 标识的 mongo 文档。尝试使用 to_param 代替，如下所示：
I see that you are passing the content.community.id as the :community_id and that object looks like a mongo document that is identified with a BSON::ObjectId. Try to use to_param instead as following:
