python - Django:openpyxl 将工作簿保存为附件

Question

您好，我有一个简单的问题。我没有在网上找到答案，也许你们中的某个人可以帮助我。

所以我想将工作簿另存为附件，但我不知道如何查看示例:

    from openpyxl import Workbook
    from openpyxl.cell import get_column_letter
    wb = Workbook(encoding='utf-8')
    dest_filename = 'file.xlsx'
    ws = wb.worksheets[0]
    ws.title = "range names"
    for col_idx in xrange(1, 40):
        col = get_column_letter(col_idx)
        for row in xrange(1, 600):
            ws.cell('%s%s'%(col, row)).value = '%s%s' % (col, row)
    ws = wb.create_sheet()
    ws.title = 'Pi'
    ws.cell('F5').value = 3.14

然后我尝试了:

response = HttpResponse(wb, content_type='application/vnd.ms-excel')
response['Content-Disposition'] = 'attachment; filename="foo.xls"'
return response

它确实返回了 xlsx 文件，但在文件中只有对象地址而不是文件的内容:

<openpyxl.workbook.Workbook object at 0x00000000042806D8>

有人可以帮忙吗？

试一试:

from openpyxl.writer.excel import save_virtual_workbook
...
response = HttpResponse(save_virtual_workbook(wb), content_type='application/vnd.ms-excel')

save_virtual_workbook 专为您的用例而设计。这是一个文档字符串:

"""Return an in-memory workbook, suitable for a Django response."""
