Rails 4路线参数和路径颠倒

Question

My application environment is Rails 4, Ruby 2.1.8

And I'm trying to add Stripe checkout button on a listing page, as you may know, Stripe's checkout doesn't require any interaction with your database so there isn't a Charges model. This also explains why the embedded ruby for the Stripe JS checkout from the example uses the form tag method instead of the form for method.

So I just want to pass the listing id and save it by myself for reference. But there is something really weird in my Rails routes behavior:

routes.rb

# stripe
resources :charges

form tag in .haml

= form_tag charges_path(@listing.id) do

And no matter how I poked around, the Param and Path are always Reversed

<form method="post" accept-charset="UTF-8" action="/111/charges">

How can I get below instead?

<form method="post" accept-charset="UTF-8" action="/charges/111">

您需要更改for路径，以便Rails知道您要传入的内容。

form_tag charges_path(id: @listing.id)
