I’ve got a very simple app where the flow looks like this:

User reads some copy, decides they want to purchase the product and fill out the form, see confirmation page.

Something is wrong in my controller but I can’t quite pinpoint it where I’m getting the error Couldn't find Customer without an ID.

class CustomersController < ApplicationController
#  before_filter :load_customer, :only => :show

  def new
    @customer = Customer.new
  end

  def create
    @customer = Customer.new(params[:customer])

    if @customer.save
      session[:customer_id] = @customer.id
      purchase
    else
      flash[:error] = "Please enter a valid email address"
      redirect_to :signup
    end
  end

  def signup
    @customer = Customer.new
  end


  def purchase
    Stripe.api_key = STRIPE['secret']
    charge = Stripe::Charge.create(
    :amount => 2000,
    :currency => "usd",
    :card => params[:stripe_token],
    :description => "My Product Name"
    )
    redirect_to receipt_path
  end

  def receipt
    @customer = Customer.find(session[:customer_id])

    @name = @customer.name
    @email = @customer.email
    @product = @customer.product
  end

  # private
  # 
  # def load_customer
  #   @customer = Customer.find(session[:customer_id])
  #   redirect_to request.path.gsub(params[:id], session[:customer_id].to_s) if params[:id] != session[:customer_id].to_s
  # end

end

I’m not sure where things are screwing up and after much Googling, I’m turning to you guys. Help would be huge.

EDIT:

Consulting with Rails console shows that my application isn’t making new customer records for some reason. Charging is working, however. Customers not being created must be a precursor to this.

    If the user routes directly to receipt action then session[:customer_id] may be nil. That’s why you get the error. This is not happened if a create (possibly) POST request is issued. In this case, the session variable has been populated before the redirection to the receipt action.
