Table entry works fine in development but not in production

Question

I have a product page that when you buy the product, it will redirect to a purchase page (the receipt and download page).

Everything works fine in development on my local computer but when a purchase goes through in production on the remote server it charges the customer (using Stripe) but doesn't create an entry in the purchase table - which doesn't allow the customer to download their product. I checked the "purchases" table in psql on the remote server and it doesn't have any rows/entries.

It is supposed to send an email as well - linking to the purchase page, which only works in development as well.

I am using PostgreSQL on both my local computer and the remote server.

charges controller:

class ChargesController < ApplicationController

  def new
    set_meta_tags noindex: true
  end

  def create
    pack = Pack.find(params[:product_id])

    customer = Stripe::Customer.create(
      :email => params[:stripeEmail],
      :source  => params[:stripeToken],
    )

    # Amount in cents
    charge = Stripe::Charge.create(
      :customer    => customer.id,
      :amount      => pack.price_in_cents,
      :description => 'Product Purchase',
      :currency    => 'usd',
    )

    purchase = Purchase.create(
      email: params[:stripeEmail],
      card: params[:stripeToken],
      amount: pack.price_in_cents,
      description: charge.description,
      currency: charge.currency,
      customer_id: customer.id,
      product_id: pack.id,
      uuid: SecureRandom.uuid,
    )

    redirect_to purchase

  rescue Stripe::CardError => e
    flash[:error] = e.message
    redirect_to new_charge_path
  end

end

purchases_controller:

class PurchasesController < ApplicationController

  def show
    @title = 'Purchase Receipt';
    @purchase = Purchase.find_by_uuid(params[:id])
    @pack = Pack.find(@purchase.product_id)
    set_meta_tags noindex: true
  end

end

Purchase model:

class Purchase < ApplicationRecord
  attr_accessor :download_token
  after_create :email_purchaser

  def to_param
    uuid
  end

  def email_purchaser
    PurchaseMailer.purchase_receipt(self).deliver
  end

  def Purchase.new_token
    SecureRandom.urlsafe_base64
  end

  def create_download
    self.download_token = Purchase.email.new_token
    update_attribute(:download, Purchase.email(download_token))
    update_attribute(:download_sent_at, Time.zone.now)
  end

end

purchase_mailer:

class PurchaseMailer < ActionMailer::Base
  layout 'purchase_mailer'
  default from: "First Last <myemail@gmail.com>"

  def purchase_receipt purchase
    @purchase = purchase
    mail to: purchase.email, subject: "Thank you for your purchase. Here's your download link, enjoy!"
  end

end

Link to purchase.show view in the sent email:

<%= link_to "DOWNLOAD", purchase_url(@purchase), target: "_blank" %>

Here are the server logs:

Here is the server log after adding ! to purchase = Purchase.create!( in the charges controller:

Here is my routes.rb File:

  resources :charges
  resources :purchases, only: [:show]

I have removed get 'purchase' => 'purchases#show', as: 'purchase' from routes.rb as it was breaking my code.

It was making the URL do this: https://mywebsite.com/purchase.uuid

Instead of this: https://mywebsite.com/purchase/uuid

After running rails routes:

On your project folder run: "rails routes" if is rails 5 or "rake routes" for older versions — Javier Menéndez Rizo, Jan 15 '19 at 13:59
It could be helpful to see your production settings (without sensitive data) in config/environments/production.rb — Javier Menéndez Rizo, Jan 15 '19 at 14:03
Can you repeat the process a get the logs again to see if there is something else? — Javier Menéndez Rizo, Jan 15 '19 at 14:40
Maybe you have not run migrations in productions and the uuid column is not present in purchases table? — MatFiz, Jan 15 '19 at 21:43
@MatFiz wow, that must be it. I just checked my table on the server via `psql` and there is no uuid column. — Jake, Jan 15 '19 at 21:48
I am glad I could help. I will provide it as an answer below, pls accept ;) — MatFiz, Jan 16 '19 at 09:29
Have you resetarted the rails server after applying the migration? The error `F, [2019-01-15T21:21:12.869293 #24540] FATAL -- : [932479d4-c710-4ac6-9159-8c3fa5299adc] ActiveModel::UnknownAttributeError (unknown attribute 'uuid' for Purchase.):` comes now from the rails model. — MatFiz, Jan 16 '19 at 11:33
@MatFiz Sorry, I meant I found the error I mentioned about the uuid by using the `!` and yes I did and it worked, please update your answer so I can accept it. — Jake, Jan 16 '19 at 11:37

I would advise you to wrap the ChargesController.create in a transaction. In case of some (eg. validation) error in Purchase.create, you end up in some partial data created in db + real transaction in Stripe. Also, it would be a good improvement to check if the purchase has been actually created:

if purchase
  redirect_to purchase
else 
  render :new, error: purchase.errors
end

Then in production GUI you will clearly see what is the problem.

Also, in your logs F, [2019-01-15T21:21:12.869293 #24540] FATAL -- : [932479d4-c710-4ac6-9159-8c3fa5299adc] ActiveModel::UnknownAttributeError (unknown attribute 'uuid' for Purchase.):, which might mean your migrations were not applied in prod and you're simply missing uuid column in Purchase.

Looks like you are getting a HEAD request. Your routes dont seem to be able to handle this. Don't worry this is kind of normal.

This is a CORS preflight check happening. Read more here: https://en.wikipedia.org/wiki/Cross-origin_resource_sharing

And

Why does a cross-origin HEAD request need a preflight check?

For rails Try Rack Cors: https://github.com/cyu/rack-cors this may help.

Essentially Rack CORS will allow your app to respond to the preflight checks appropriately.

Table entry works fine in development but not in production
