UnicodeEncodeError与EmailMessage Django上的attach_file错误 [英] UnicodeEncodeError with attach_file on EmailMessage Django error
问题描述
因此，当我尝试在Django中使用EmailMessage发送电子邮件时，会出现此错误.
So I get this error when I try to send an email with EmailMessage in Django.
/checkout/
'ascii' codec can't encode character u'\u0161' in position 15:
邮件正文包含一些会破坏脚本的unicode字符.
The body of the message contains some unicode character that breaks the script.
问题是，如果我省略附件，或者如果主体不包含任何unicode字符，一切都将正常工作.主题可以包含没有unicode错误的unicode字符.因此，仅在正文和附件中与Unicode字符结合使用时才发生.对我来说这似乎是个虫子.
The thing is that everything works just fine if I omit the attachment OR if the body doesn't contain any unicode characters. The subject can contain unicode characters with no unicode error. So it happens only in combination with unicode characters in the body and the attached file. This seems like a bug to me.
附件是生成的pdf文件.
The attachemnt is a generated pdf file.
在Ubuntu 10.04，apache2，mod_wsgi，python 2.6.5，Django 1.5上运行的代码
The code running on Ubuntu 10.04, apache2, mod_wsgi, python 2.6.5, Django 1.5
我正在使用的代码是
t = loader.get_template('orders/invoice_email.html')
c = {
'order': order,
}
email = EmailMessage(subject, t.render(Context(c)), from_mail, [to, ])
email.encoding = "utf-8"
email.content_subtype = "html"
email.attach_file(invoice.name)
email.send()
和追溯
