提取多個PARAMS從URL

Question

我有一個Rails應用程序，我想從這個URL中提取2點不同的ID：

http://localhost:3000/shopping/suppliers/2/products/1

它看起來像兩個值都在那裏development.log展望。

我想知道如何將這些參數暴露給控制器，它只是params[:supplier_id]和params[:id]？

Started GET "/shopping/suppliers/2/products/1" for 127.0.0.1 at 2016-04-22 18:28:19 +1000 
Processing by Shopping::ProductsController#show as HTML 
    Parameters: {"supplier_id"=>"2", "id"=>"1"} 
    Product Load (30.1ms) SELECT "products".* FROM "products" WHERE "products"."permalink" = $1 ORDER BY "products"."id" ASC LIMIT 1 [["permalink", "1"]] 
    Product Load (0.8ms) SELECT "products".* FROM "products" WHERE "products"."id" = $1 LIMIT 1 [["id", 1]] 
    User Load (19.6ms) SELECT "users".* FROM "users" WHERE "users"."id" = $1 ORDER BY "users"."id" ASC LIMIT 1 [["id", 1]] 
    CACHE (0.0ms) SELECT "products".* FROM "products" WHERE "products"."permalink" = $1 ORDER BY "products"."id" ASC LIMIT 1 [["permalink", "1"]] 
    CACHE (0.0ms) SELECT "products".* FROM "products" WHERE "products"."id" = $1 LIMIT 1 [["id", "1"]]

是的，你應該能夠用這些密鑰來訪問你的價值觀：

params[:supplier_id] 
params[:id] 

這是奇怪爲什麼你還沒有可以發佈您的問題之前嘗試過自己的建議。 :)
