You cannot do this uploadfolder= lambda r:... But this is a chicken-egg problem. You want r to be the row but the row is not created until after the file is uploaded therefore you cannot specify the upload folder as function of something that happens after.
Please explain to us in english of the folder should depend on the upload and perhaps we can suggest a way to do it.
