Question

Maintenant, je n'ai pas de problèmes au sujet de la conversion de ce csv ou en le téléchargeant j'ai un problème d'économie à django modèle à filefield L'exemple de code minmized:

def download_convert_reports_s3_temp(): 
    def get_report_url(): 
     bucket_name = 'temp_bucket' 
     conn = boto.connect_s3(AWS_ACCESS_KEY_ID, 
           AWS_SECRET_ACCESS_KEY) 
     bucket = conn.get_bucket(bucket_name) 
     key = bucket.get_key('TEMP_2017-01-10.csv') 
     return key.generate_url(expires_in=600) 

    def get_doc(): 
     return Doc.objects.get(owner=User.objects.first()) 

    def get_file(file): 
     file_temp = NamedTemporaryFile(delete=True) 
     file_temp.write(file.content) 
     file_temp.flush() 
     return File(file_temp) 

    def convert_csv_to_xlsx(): 
     request = requests.get(get_report_url()) 
     csvfile = get_file(request) 

     from django.conf import settings 
     excelFile = xlsxwriter.Workbook('report.xlsx', { 
              'strings_to_numbers': True, 
              'default_date_format': 'yy/mm/dd', 
              'tmpdir': settings.MEDIA_ROOT + 
                 '/documents/%s'.format(file.name.rsplit('.')[0] + '.xlsx') 
             } 

     excelFile = get_doc().file 
     worksheet = excelFile.add_worksheet() 
     worksheet.write('A1', 'data') 
     worksheet.write('B1', 'data') 
     worksheet.write('C1', 'data') 
     worksheet.write('D1', 'data') 
     worksheet.write('E1', 'data') 
     # Start from the first cell. Rows and columns are zero indexed. 
     row = 1 
     col = 0 
     with open(csvfile, 'rb') as f: 
      content = csv.reader(f) 
      # Iterate over the data and write it out row by row. 
      for row_data in content: 
       for data in row_data: 
        worksheet.write(row, col, data) 
        col += 1 
       row += 1 
       col = 0 

     f.close() 
     excelFile.close() 

    return convert_csv_to_xlsx()
