[Answered ]-CSV Mapping coercing to Unicode: need string or buffer, list found

self.data is a list (in CSV):

self.data = [row for row in csv.reader(f)]
self.data = [row for row in csv.reader(file.read().splitlines())]

hence this_file is a list:

this_file = csv_object.get_data()

So when you do new_object = CSVImport(csvfile=this_file,...) seems that CSVImport is expecting csvfile to be a string but you’re passing it a list.

I don’t know exactly what you’re trying to accomplish but that seems to be the error.

Hope this helps!
