谢谢你的洞察力 您可以根据门店id确定产品范围
class ProductsController < ApiController
def index
store = Store.find(params[:store_id])
respond_with store.products
end
end
您会发现37是参数中提供的路由的一部分,可能在
:store_id
中。检查rake路由
以确保。您希望在路由中嵌套资源:
resources :stores do
resources :products
end
所以你有这些路线:
GET /stores/:id
GET/POST /stores/:store_id/products
PUT/DELETE /stores/:store_id/products/:id
GET /stores/:id
GET/POST /stores/:store_id/products
PUT/DELETE /products/:id
您可能还需要浅路由,以避免深度嵌套的资源:
resources :stores, shallow:true do
resources :products
end
所以你有这些路线:
GET /stores/:id
GET/POST /stores/:store_id/products
PUT/DELETE /stores/:store_id/products/:id
GET /stores/:id
GET/POST /stores/:store_id/products
PUT/DELETE /products/:id
获得路线后,您可以先加载父商店,然后使用产品关联:
@store = Store.find(params[:store_id])
@products = store.products
