get this error ?? ActiveRecord::UnknownAttributeError (unknown attribute: uuid): which I have used in my charges controller.rb file

class ChargesController < ApplicationController

def create
  # Amount in cents

  customer = Stripe::Customer.create(
    :email => params[:stripeEmail],
    :card  => params[:stripeToken]
  )
  charge = Stripe::Charge.create(
    :customer    => customer.id,
    :amount      => params[:amount],
    :description => 'Open Cinema',
    :currency    => 'gbp'
  )
  purchase = Purchase.create(email: params[:stripeEmail],
    card: params[:stripeToken], amount: params[:amount],
    description: charge.description, currency: charge.currency,
    customer_id: customer.id, product_id: 1, uuid: SecureRandom.uuid)

  redirect_to purchase


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

have done heroku restart and added the uuid to my purchases model

class AddUuidToPurchases < ActiveRecord::Migration
  def change
    add_column :purchases, :uuid, :string
  end
end



class ChargesController < ApplicationController

def create
  # Amount in cents
require 'SecureRandom'

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

  charge = Stripe::Charge.create(
    :customer    => customer.id,
    :amount      => params[:amount],
    :description => 'Open Cinema',
    :currency    => 'gbp'
  )

  purchase = Purchase.create(email: params[:stripeEmail],
    card: params[:stripeToken], amount: params[:amount],
    description: charge.description, currency: charge.currency,
    customer_id: customer.id, product_id: 1, uuid: SecureRandom.uuid)

  redirect_to purchase


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

Include require 'securerandom' in your model and deploy again.
