xml_http_request :put errata -- any workaround?

Hi folks!

I’m working through the depot application, and I’ve run into the problem whereby the user_stories_test.rb, as given in the book, throws error:

NoMethodError: undefined method `[]’ for :put:Symbol

This is captured in the errata, but I’ll be jig-swiggered if I can find a workaround. Does anyone have any suggestions for getting this to work? Should I use a good ‘ol POST request instead of an XHR?

Thanks in advance for any help you can provide!

xml_http_request :put, ”/store/add_to_cart”, :id => ruby_book.id
works just fine for me. Are you sure you’re passing it the correct parameters?
