Question

在Rails 4.2.6中，我正在创建像这样的嵌套资源

routes.rb中：

resources :analysis, param: :project_id do 
  resources :configuration 
end

resources :decision, param: :project_id do
  resources :configuration
end

当我在分析或决策控制器中时，它工作正常。但是，当我在配置控制器中时，我会收到参数:analysis_project_id或:decision_project_id。我该如何更改，以便仍然收到:project_id？

我不想自定义配置控制器，以便知道它嵌套在不同的资源中。

就是这样，您无需在此处发送params，它会自动与您的action对应。

  resources :analysis do 
       resources :configuration  
  end

如果你需要这样的路线

 analysis_configuration_index GET       /analysis/:analysis_id/configuration(.:format)          configuration#index
                              POST      /analysis/:analysis_id/configuration(.:format)          configuration#create
 new_analysis_configuration GET       /analysis/:analysis_id/configuration/new(.:format)      configuration#new
 edit_analysis_configuration GET       /analysis/:analysis_id/configuration/:id/edit(.:format) configuration#edit
 analysis_configuration GET       /analysis/:analysis_id/configuration/:id(.:format)      configuration#show
                         PATCH     /analysis/:analysis_id/configuration/:id(.:format)      configuration#update
                         PUT       /analysis/:analysis_id/configuration/:id(.:format)      configuration#update
                         DELETE    /analysis/:analysis_id/configuration/:id(.:format)      configuration#destroy
          analysis_index GET       /analysis(.:format)                                     analysis#index
                         POST      /analysis(.:format)                                     analysis#create
            new_analysis GET       /analysis/new(.:format)                                 analysis#new
           edit_analysis GET       /analysis/:id/edit(.:format)                            analysis#edit
                analysis GET       /analysis/:id(.:format)                                 analysis#show
                         PATCH     /analysis/:id(.:format)                                 analysis#update
                         PUT       /analysis/:id(.:format)                                 analysis#update
                         DELETE    /analysis/:id(.:format)                                 analysis#destroy

重命名嵌套资源中的参数
