Couldn't find product without ID using Stripe - ruby

Question

I am trying to complete my payment set up in Ruby but am struggling to gt the order confirmation screen to print. I have set up my partial for the payment as such.
<script
src="https://checkout.stripe.com/checkout.js" class="stripe-button"
data-key="<%= Rails.configuration.stripe[:publishable_key] %>"
data-image="<%= asset_path(#product.image_url) %>"
data-name="<%= #product.name %>"
data-description="<%= #product.description %>"
data-amount="<%= #product.price*100.to_i %>">
</script>
My payment controller.
class PaymentsController < ApplicationController
before_action :authenticate_user!
def create
#product = Product.find(params[:product_id])
#user = current_user
token = params[:stripeToken]
# Create the charge on Stripe's servers - this will charge the user's card
begin
charge = Stripe::Charge.create(
amount: #product.price, # amount in cents, again
currency: "eur",
source: token,
description: params[:stripeEmail]
)
if charge.paid
UserMailer.order_confirmation(#user, #product).deliver_now
Order.create!(
:product_id => #product.id,
:user_id => #user.id,
:total => #product.price_show
)
flash[:success] = "Your payment was processed successfully"
end
rescue Stripe::CardError => e
body = e.json_body
err = body[:error]
flash[:error] = "Unfortunately, there was an error processing your payment: #{err[:message]} Your card has not been charged. Please try again."
end
redirect_to product_path(#product), notice: "Thank you for your purchase."
end
end
and my routes file.
Rails.application.routes.draw do
devise_for :users, path: '', path_names: { sign_in: 'login', sign_out: 'logout' },
controllers: {registrations: "user_registrations"}
resources :products do
resources :comments
end
post 'payments/create'
resources :users
resources :orders, only: [:index, :show, :create, :destroy]
resources :users, except: [:index]
get 'simple_pages/about'
get 'simple_pages/contact'
root 'simple_pages#landing_page'
post 'simple_pages/thank_you'
mount ActionCable.server => '/cable'
# For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
end
The form within product show.html.erb
<%= form_with(url: '/payments/create') do |form| %>
<%= render partial: "shared/stripe_checkout_button" %>
<%= hidden_field_tag(:product_id, #product.id) %>
<% end %>
However, when I try to complete a test payment, I have the action controller pop up with "Couldn't find Product without an ID". I thought this was defined in the create section but I am not sure how to rectify this. Any suggestions would be greatly appreciated.

Answer 1

The :product_id is not set in your form post,
1. Quick Solution:
your form url could be like this:
<%= form_with(url: "/payments/create?#{product_id=#product.id}") do |form| %>
2. Better Way:
configure you routes for payments already has product id:
# routes.rb
resources :products do
resources :comments
resources :payments
end
form url:
<%= form_with(url: product_payments_path(#product)) do |form| %>
