Redirect_to with post params

Question

I write this redirection :

redirect_to list_order_submit_path(:provider_id => @cart_item.product.provider.id)

But this show the Provider_id in URL:

localhost:3000/order/list?provider_id=1

How can i pass the variable not in URL or how I make this get to a post param ?

Answer 1

I'll quote the beginning of this SO answer for later viewers:

You can't do a redirect and send POST data at the same time in the HTTP spec.

Answer 2

You shouldn't do it. What you want is a GET petition because you are listing elements and not modifying them.

So passing the argument in the header is correct and the best practice.
