Hi,

I’m having problems in Ch. 13 integration test test_buying_a_product.

When the test does post_via_redirect the test Fails.

post_via_redirect "/orders",
    order: { name:     "Dave Thomas",
             address:  "123 The Street",
             email:    "dave@example.com",
             pay_type: "Check" }

Test output

test_buying_a_product                                               ERROR
        You have a nil object when you didn't expect it!
        You might have expected an instance of Array.
        The error occurred while evaluating nil.map
        STDERR:
        Exception `ActionView::Template::Error' at app/views/orders/_form.html.erb:28:in `block in _app_vie\
ws_orders__form_html_erb__2737086846954495514_28501660'

Test.log shows

When I do the same steps in the browser I get no errors, and all is well.
