Hello, I'm new to ruby and rails... I was planning to use the spreadsheet gem to open the files but it doesn't support xlsx. I saw this as an example on how to do the same using paperclip @workbook = Spreadsheet.open(MyFile.first.attachment.to_file) I imagine with roo would be something like # In this example the model MyFile has_attached_file :attachment @workbook = Roo::Excelx.new(MyFile.first.attachment.to_file) **Like I said I'm new to Ruby and Rails, so I don't know what's "first", I assume it refers to the first record (the lastest) on the MyFile corresponding Table** Is this the right way to do it? I find the use of "new" confusing, although it says loads an Excel Spreadsheet for Excel .xlsx files I think it's creating a new one instead of loading the attachment. Thank you for your guidance in advance.
