How do I resolve this error with Stripe checkout on wizard page via wicked gem?

Robert Hopman asked in Rails

Right now I get this error message when the submit.html.erb loads: Cannot charge a customer that has no active card.

I want to understand how I can improve my controller. The goal is to not have the error message when the submit page loads. But only if there's an actual user submitting false information.

class SubmissionsController < ApplicationController
include Wicked::Wizard
steps :name, :details, :comments, :submit, :thankyou

def show
@company = Company.find(params[:company_id])
render_wizard
end

def update
@company = Company.find(params[:company_id])

one time checkout
@amount = 50
@description = 'Premium Package'

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

Stripe::Charge.create(
:customer    => customer.id,
:amount      => @amount,
:description => @description,
:currency    => 'eur'
)

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

params[:company][:status] = step.to_s
params[:company][:status] = 'active' if step == steps.last
@company.update_attributes(company_params)
render_wizard @company
end

private ...

Here's the submit.html.erb

< %= form_for @company, url: wizard_path, method: :put do |f| %>
< article>
< % if flash[:error].present? %>
< div id="error_explanation">
< p><%= flash[:error] %></p>
</ div>
< % end %>
< label class="amount">
< span>Amount: €0.50</span>
< /label>
< /article>

< script src="https://checkout.stripe.com/checkout.js" class="stripe-button"
data-key="<%= Rails.configuration.stripe[:publishable_key] %>"
data-description=<% @description %>
data-amount=<% @amount %>
data-locale="auto"></script>
< % end %>

If I can provide more context, please advise.

Added a couple of spaces in the submit.html.erb template, otherwise it wouldn't be visible.

Hey Robert,

When Stripe tells you that the customer doesn't have a card to charge, that means that your form probably hasn't submitted the stripeToken param to attach to the user. You'll want to make sure that's getting passed over.

Refactored into:

class SubmissionsController < ApplicationController
include Wicked::Wizard
steps :name, :details, :comments, :submit, :thankyou

def show
    get_company
    set_package
    render_wizard
end

def update
    case step
    when :thankyou
        get_company
        render_wizard @company
    when :submit
        get_company
        set_package
        if request.put?
            create_customer
            do_payment
            render_wizard @company
        end
    else
        get_company
        params[:company][:status] = 'active' if step == steps.last
        @company.update_attributes(company_params)
        render_wizard @company
    end
end

def get_company
    @company = Company.find(params[:company_id])
end

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

def set_package
    @amount = 50
    @amount_in_decimals = @amount / 100.00
    @description = "Premium Package"
end

def do_payment
    Stripe::Charge.create(
        :customer    => @customer.id,
        :amount      => @amount,
        :description => @description,
        :currency    => "eur"
    )

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