使用xlsxwriter将CSV转换为excel并将其保存到django模型

现在我没有任何关于转换这个csv或下载它的问题我有一个问题，将它保存到filefield的django模型最小化的示例代码：

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() 

现在的问题，我真的不知道要保存这个excel文件到doc.file ，我试过django fieldfile保存

  def convert_csv_to_xlsx(): csvfile = get_file() from django.conf import settings excelFile = xlsxwriter.Workbook(filename=settings.MEDIA_ROOT + '/documents%s' % ( csvfile.name.rsplit('.')[0] + '.xlsx')) bold = excelFile.add_format({'bold': 1, 'align': 'left', 'bg_color': 'red', 'color': 'white'}) worksheet = excelFile.add_worksheet() worksheet.set_column(0, 4, width=15) worksheet.write('A1', 'Sender MSISDN', bold) worksheet.write('B1', 'Reciever MSISDN', bold) worksheet.write('C1', 'Amount', bold) worksheet.write('D1', 'Transaction ID', bold) worksheet.write('E1', 'Datetime', bold) # Start from the first cell. Rows and columns are zero indexed. row = 1 col = 0 # Iterate over the data and write it out row by row. for row_data in csv.reader(csvfile): for idx, data in enumerate(row_data): if idx == 0: worksheet.write(row, col, data) elif idx == 1: worksheet.write(row, col, data) elif idx == 2: worksheet.write(row, col, data) elif idx == 3: worksheet.write(row, col, data) elif idx == 4: worksheet.write(row, col, data) col += 1 row += 1 col = 0 csvfile.close() doc = get_doc() now = datetime.now() excelFile.close() doc.file.save( name='RECHARGE_%d-%s-%s.xlsx' % (now.year, validate_date(now.month), validate_date(now.day) ), content=File(open(settings.MEDIA_ROOT + '/documents%s' % ( csvfile.name.rsplit('.')[0] + '.xlsx',))) ) os.remove(settings.MEDIA_ROOT + '/documents%s' % ( csvfile.name.rsplit('.')[0] + '.xlsx'), )
