Question

我不确定如何提出这个问题......

但我正在使用嵌套的ROUTES，如下所示。

我想知道使用params[:business_id]始终可以找到商家ID ，显然除了要求我使用params[:id]的实际业务控制器之外。

有没有办法将路径资源ID参数更改为始终为:business_id，而不必像Business.find(params.values_at(:business_id, :id).first)？

Answer 1

如果您使用的是Rails 4+，则可以使用param方法中的resources选项执行此操作

Overriding Route Parameters

假设您的代码看起来像

resources :businesses

您可以添加一个参数

resources :businesses, param: :business_id

哪个应该生成路线

                    businesses GET    /businesses(.:format)                                                                                                     businesses#index
                               POST   /businesses(.:format)                                                                                                     businesses#create
                  new_business GET    /businesses/new(.:format)                                                                                                 businesses#new
                 edit_business GET    /businesses/:business_id/edit(.:format)                                                                                            businesses#edit
                      business GET    /businesses/:business_id(.:format)                                                                                                 businesses#show
                               PATCH  /businesses/:business_id(.:format)                                                                                                 businesses#update
                               PUT    /businesses/:business_id(.:format)                                                                                                 businesses#update
                               DELETE /businesses/:business_id(.:format)

<强>更新

由于您使用相同的嵌套资源生成这些路由，因此您必须执行以下操作

resources :businesses, param: :business_id 
resources :businesses, only: [] do
  resources :exports
  ...
end

Rails路由：更改资源标识符路径名称？总是使用params [：model_id]而不是params [：id]
