Retrieve Stripe charge id upon failed charge

Question

I am trying to retrieve the Stripe charge id upon a failed charge, so I can retrieve my record thanks to that id when the charge.failed hook is fired. I tried inspect the exception fired but I cannot find any way to get it. Here is my code :

  def charge
    token = params[:stripeToken]
    type = params[:stripeTokenType]
    metadata = {}
    record = Record.new(amount: Random.rand(2000), valid: false)
    charge = nil
    begin
      charge = Stripe::Charge.create(
          {
              amount: 2000,
              currency: 'eur',
              source: token,
              description: 'Test',
              metadata: metadata
          }, { stripe_account: 'xxxxx' })
      record.stripe_charge_id
      flash[:notice] = 'Transaction validée'
    rescue Exception => e
      record.error = e.code
      flash[:error] = 'Erreur de paiement'
    end
    flash[:error] = 'Erreur de paiement' unless record.save || flash[:error]
    redirect_to :stripe_test
  end

Answer 1

I finally used the meta data to store my record id with the charge. So I am able to retrieve it using this metadata.

charge = Stripe::Charge.create(
    {
        amount: 2000,
        currency: 'eur',
        source: token,
        description: 'Test',
        metadata: { record_id: 23 }
    }, { stripe_account: 'xxxxx' })
