Get Stripe charge information rails 5 create order - ruby

Question

So I'm implementing Stripe and users are able to purchase successfully, however, I would like to get the charge information, last 4 card numbers, card type etc so I can generate receipts using https://github.com/excid3/receipts.
Here is what I have so far:
PaymentsController
class PaymentsController < ApplicationController
before_action :authenticate_user!
def create
token = params[:stripeToken]
#course = Course.find(params[:course_id])
#user = current_user
begin
charge = Stripe::Charge.create(
amount: (#course.price*100).to_i,
currency: "gbp",
source: token,
description: params[:stripeEmail],
receipt_email: params[:stripeEmail]
)
if charge.paid
Order.create(
course_id: #course.id,
user_id: #user.id,
Amount: #course.price
)
end
flash[:success] = "Your payment was processed successfully"
rescue Stripe::CardError => e
body = e.json_body
err = body[:error]
flash[:error] = "Unfortunately, there was an error processing your payment: #{err[:message]}"
end
redirect_to course_path(#course)
end
end
OrdersController
class OrdersController < ApplicationController
layout proc { user_signed_in? ? "dashboard" : "application" }
before_action :authenticate_user!
def index
#orders = Order.includes(:course).all
end
def show
#order = Order.find(params[:id])
respond_to do |format|
format.pdf {
send_data #order.receipt.render,
filename: "#{#order.created_at.strftime("%Y-%m-%d")}-aurameir-courses-receipt.pdf",
type: "application/pdf",
disposition: :inline
}
end
end
def create
end
def destroy
end
end
Order.rb
class Order < ApplicationRecord
belongs_to :course
belongs_to :user
validates :stripe_id, uniqueness: true
def receipt
Receipts::Receipt.new(
id: id,
subheading: "RECEIPT FOR CHARGE #%{id}",
product: "####",
company: {
name: "####",
address: "####",
email: "####",
logo: "####"
},
line_items: [
["Date", created_at.to_s],
["Account Billed", "#{user.full_name} (#{user.email})"],
["Product", "####"],
["Amount", "£#{amount / 100}.00"],
["Charged to", "#{card_type} (**** **** **** #{card_last4})"],
["Transaction ID", uuid]
],
font: {
normal: Rails.root.join('app/assets/fonts-converted/font-files/AvenirBook.ttf')
}
)
end
end
schema.rb
create_table "orders", force: :cascade do |t|
t.integer "user_id"
t.integer "course_id"
t.integer "stripe_id"
t.integer "amount"
t.string "card_last4"
t.string "card_type"
t.integer "card_exp_month"
t.integer "card_exp_year"
t.string "uuid"
t.index ["course_id"], name: "index_orders_on_course_id"
t.index ["user_id"], name: "index_orders_on_user_id"
end
How would I go about getting the charge information?

Answer 1

All the information you need is in the charge object you created.
if charge.paid
Order.create(
course_id: #course.id,
user_id: #user.id,
amount: #course.price,
card_last4: charge.source.last4,
card_type: charge.source.brand,
card_exp_month: charge.source.exp_month,
card_exp_year: charge.source.exp_year
)
end
See https://stripe.com/docs/api/ruby#charge_object for all the information available to you about a charge.

Answer 2

I guess you are not storing the Stripe Charge ID anywhere on successful payment.
My suggestion, store the charge ID in your Order record
if charge.paid
Order.create(
course_id: #course.id,
user_id: #user.id,
amount: #course.price,
stripe_charge_id: charge.id
)
end
In your receipt method you can fetch the stripe charge as follows:
def receipt
stripe_charge = Stripe::Charge.retrieve(stripe_charge_id)
...
end
The stripe_charge objects contains all the information and you can use whatever data you need.
Hope this helped.
