Rails Routes：更改資源標識符路徑名？ 始終使用 params[:model_id] 而不是 params[:id]

Question

我不知道怎么問這個問題...

但我正在使用嵌套的 ROUTES，如下所示。

我喜歡知道總是可以使用params[:business_id]找到業務 ID ，顯然除了需要我使用params[:id]的實際業務控制器。

有沒有辦法將路由資源 id 參數更改為始終為: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+，則可以使用resources方法中的param選項來執行此操作

覆蓋路由參數

假設您的代碼看起來像

resources :businesses

您可以這樣添加一個參數

resources :businesses, param: :business_id

哪個應該產生路線

                    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)

UPDATE

由於您使用相同的嵌套資源生成這些路線，因此必須執行以下操作

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

Answer 2

更干凈的方式是使用member

resources :businesses, param: :business_id do
  member do
    resources :exports
    ...
  end
end
