python - 发送附件 'file'时Django 1.5错误对象没有属性 '__getitem__'

Question

我正在尝试通过电子邮件发送附件，pdf 但我收到以下错误 'file' object has no attribute '__getitem__'

这是我的代码。

created_pdf = open(filename)

from_email = settings.DEFAULT_EMAIL
email = EmailMessage('KenyaBuzz Tickets for %s'%seat1.movie, "There's a pdf attached with the tickets, please print it and provide it at...", from_email,
        [seat1.user.email],
        )
email.attach(filename, created_pdf, 'application/pdf')
email.send()

Answer 1

attach 的第二个参数应该是数据，而不是文件对象。

email.attach(filename, created_pdf.read(), 'application/pdf')

但是最好使用attach_file，它直接接受一个文件名:

email.attach_file(filename)
