如何将保存在 Django FileField 中的文件作为附件发送？
如何发送包含保存在 FileField 中的文件的邮件？我不知道如何访问下面代码中的文件。
mail = EmailMessage(subject, message, 'from@from,com', ['[email protected]'])
mail.attach(?, ?, 'application/pdf')
mail.send()
编辑
文件
f = list_pca.pdf_file.open(mode='rb')
我尝试打开其中 list_pca 是实例的
class ListPCA(models.Model):
pdf_file = models.FileField(upload_to=get_file_path_j, null=True, blank=True)
，但收到错误“没有这样的文件或目录”，因为路径错误。
并
list_pca.pdf_file.path
返回错误的路径。由于 upload_to 选项，它不是应该知道文件在哪里吗？
谢谢

how can I send a mail with a file saved in a FileField? I don't know how to access the file in the code below.
mail = EmailMessage(subject, message, 'from@from,com', ['[email protected]'])
mail.attach(?, ?, 'application/pdf')
mail.send()
EDIT
I tried to open the file with
f = list_pca.pdf_file.open(mode='rb')
where list_pca is an instance of
class ListPCA(models.Model):
pdf_file = models.FileField(upload_to=get_file_path_j, null=True, blank=True)
but I get an error "No such file or directory", because the path is wrong.
and
list_pca.pdf_file.path
return the wrong path too. Isn't it supposed to know where is the file thanks to the upload_to option?
Thanks
Thanks

由于您使用的是 EmailMessage，因此您也可以将附件 kwarg 传递给它。
Since you're using EmailMessage, you can just pass it the attachments kwarg as well.
通常，就像 aganders3 建议的那样，我会使用：
但是，我注意到它对于包含空格的附件会失败。
Ordinarily, like aganders3 suggested, I would use:
But, I noted that it fails for attachments containing spaces.
我认为这可以做到：
mail.attach(os.path.basename(myfile.name), myfile.read(), 'application/pdf')我可能会忽略 MIME 编码步骤，但 IIRC mail.attach 会做到这一点。
I think this will do it:
mail.attach(os.path.basename(myfile.name), myfile.read(), 'application/pdf')I might be overlooking a MIME-encoding step, but IIRC mail.attach will do that.
尝试：
Try:
其他建议应该有效，但您也可以这样做：
您可以选择传递 MIME 类型作为第二个参数，但如果您不提供它，它只是尝试从文件名中找出它。
The other suggestions should work, but you can also do:
You can optionally pass the MIME-type as the second argument, but it just tries to figure it out from the file name if you don't provide it.
