Question

我使用xlwt模块创建了excel对象。但是，当我尝试通过电子邮件将其作为附件EmailMessage()尝试通过“AttributeError: 'int' object has no attribute 'lower'进行序列化和错误时。如何在Django中通过电子邮件发送此附件？

  File "/home/git/bot_server/bot_server/bot_data/views.py", line 590, in email_export
    email.send()
  File "/home/one/.virtualenvs/bot/local/lib/python2.7/site-packages/django/core/mail/message.py", line 274, in send
    return self.get_connection(fail_silently).send_messages([self])
  File "/home/one/.virtualenvs/bot/local/lib/python2.7/site-packages/django/core/mail/backends/console.py", line 34, in send_messages
    self.write_message(message)

    msg = message.message()

    msg = self._create_message(msg)

    return self._create_attachments(msg)

    attachment = self._create_mime_attachment(content, mimetype)
  File "/home/one/.virtualenvs/bot/local/lib/python2.7/site-packages/django/core/mail/message.py", line 327, in _create_mime_attachment
    Encoders.encode_base64(attachment)

    encdata = _bencode(orig)

    hasnewline = (s[-1] == '\n')

    return self._headers[header.lower()][1]
AttributeError: 'int' object has no attribute 'lower'

电子邮件功能：

def email_export(export, user_email):
    subject = 'Stuff'
    from_address = 'noreply@foo'
    body = "Hello"
    recip = [user_email]
    email = EmailMessage(subject, body, from_address, recip)
    email.attach('community_support_excel.xls', export, 'application/ms-excel')
    email.send()

一些excel功能：

def export_xls(queryset):
    response = HttpResponse(mimetype='application/ms-excel')
    response['Content-Disposition'] = 'attachment; filename=mymodel.xls'
    wb = xlwt.Workbook(encoding='utf-8')
    ws = wb.add_sheet("MyModel")

    more stuff.....
    wb.save(response)
    return response

问题是我试图通过电子邮件发送HTTPResponse对象作为不允许的附件。我要做的是将excel表存储在用io.BytesIO（）创建的对象中。然后使用export_object.getvalues（）发送附件。

串行化Excel附件时，Django 1.6 EmailMessage模块错误
