How do I send as an attachment a file save in a FileField in Django?

Question

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', ['to@to.com'])
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

Answer 1

mail = EmailMessage(subject, message, 'from@from,com', ['to@to.com'])
mail.attach('arbitrary_filename', myfile.read(), 'application/pdf')
mail.send()

Since you're using EmailMessage, you can just pass it the attachments kwarg as well.

email = EmailMessage(subject, message, 'from@from,com', ['to@to.com'], 
    attachments=(('foo.pdf', myfile.read(), 'application/pdf'),))

Answer 2

Ordinarily, like aganders3 suggested, I would use:

mail.attach_file(myfile.path) as well

But, I noted that it fails for attachments containing spaces.

Answer 3

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.

Answer 4

Try:

myfile = mymodel.somefilefield

mail = EmailMessage(subject, message, 'from@from,com', ['to@to.com'])
mail.attach('File Name', myfile.path, 'application/pdf')
mail.send()

Answer 5

The other suggestions should work, but you can also do:

mail.attach_file(myfile.path)

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.
