编辑：我可以在本地机器上发送附件，但不能在 Heroku 上。我将附加代码更改为：

if docfile:
    email.attach_file(docfile.name)

这可以在本地、shell 中以及当我运行我的应用程序的本地主机服务器时工作。

所以我一直在尝试让 django 发送带有附件的电子邮件，这些附件存储为故事模型中的 File 对象。我有一个任务来处理这个：

from celery import task
from django.core.mail.message import EmailMessage
from django.core.files.storage import default_storage
from apps.account.models import UserProfile

@task(name='send-email')
def send_published_article(sender, subject, body, attachment=None):
    recipients = []
    for profile in UserProfile.objects.all():
        if profile.user_type == 'Client':
            recipients.append(profile.user.email)
    email = EmailMessage(subject, body, sender, recipients)
    try:
        docfile = default_storage.open(attachment.name, 'w+')
        if docfile:
            email.attach_file(docfile.name)
        else:
            pass
    except:
        pass
    email.send()

我一直在尝试查找 shell 的错误，在我到达最后一行并运行 email.send() 之前，一切似乎都很好。shell 会显示此错误跟踪：

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/home/vagrant/nns/local/lib/python2.7/site-packages/django/core/mail/message.py", line 248, in send

  File "/usr/lib/python2.7/email/encoders.py", line 45, in encode_base64
encdata = _bencode(orig)
  File "/usr/lib/python2.7/email/encoders.py", line 31, in _bencode
hasnewline = (s[-1] == '\n')
  TypeError: 'File' object does not support indexing

谁能帮我理解我做错了什么？

我的猜测是您将文件传递给附加函数而不是文件内容。

调用read()文件对象。

docfile = default_storage.open(attachment.name, 'w+')
if docfile:
    email.attach(docfile.name, docfile, 'image/jpg')
                                   #  ^^ should be docfile.read()

问题是文件模式（我需要使用'r'）。感谢 Tomita 和 Manjunath 的部分答案。谢谢。

from celery import task
from django.core.mail.message import EmailMessage
from django.core.files.storage import default_storage
from apps.account.models import UserProfile

@task(name='send-email')
def send_published_article(sender, subject, body, attachment=None):
    recipients = []
    for profile in UserProfile.objects.all():
        if profile.user_type == 'Client':
            recipients.append(profile.user.email)
    email = EmailMessage(subject, body, sender, recipients)
    if attachment:
        email.attach(attachment.name, 'r')
    email.send()
