Extrakt mehr params von url

Question

Ich habe eine Rails-Anwendung, und ich mag 2 verschiedene IDs von dieser URL extrahieren:

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

am development.log Blick scheint es, wie beiden Werte sind.

Ich frage mich, wie ich diese Parameter dem Controller aussetzen kann, ist es nur params[:supplier_id] und params[:id]?

Answer 1

Ja, sollten Sie in der Lage sein, Ihre Werte mit den Tasten zuzugreifen:

params[:supplier_id] 
params[:id] 

Es wierd ist, warum Sie Ihren eigenen Vorschlag nicht versucht haben, bevor Sie Ihre Frage veröffentlichen. :)
