I have the following function in JS for a drag and drop file uploader: function uploadFile(file){ var xhr = new XMLHttpRequest(); var upload = xhr.upload; var uri "/imagebooks/upload_supporting_image/?authenticity_token=" + $(''meta[name=csrf-token]'').attr("content"); xhr.open(''POST'', uri, true); xhr.setRequestHeader(''X-Filename'', file.fileName); xhr.send(file); } This works properly. I''m trying to create a spec to test the function with rspec- anyone know how I can mimic this? I''ve tried: before(:each) do @image = File.open("#{Rails.root}/public/images/test/test.jpg", ''rb'') end describe ''Upload Supporting Image method'' do it ''should read a binary string and write a file with it'' do request.env[''X-Filename''] = ''test.jpg'' xhr :post, :upload_supporting_image, @image end end But it doesn''t work as expected. Any help is greatly appreciated! -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
