How to Email a Django FileField as an Attachment?

I need to send a models.FileField as an email attachment using Django. I've seen snippets that show how to do this with the raw request.FILES data (which still contains the Content-Type), but have not been able to find anything that shows how to do it once you've already saved the file in a models.FileField. The content type seems to be inaccessible from the models.FileField.

Can someone give me an example of how this would work? I'm beginning to think that I might have to store the Content-Type in the model when I save the file.

Thanks!

I am using django-storages and so .path raises

NotImplementedError: This backend doesn't support absolute paths.

To avoid this, I simply open the file, read it, guess the mimetype and close it later, but having to use .attach instead of .attach_file magic.

from mimetypes import guess_type
from os.path import basename


f = model.filefield
f.open()
# msg.attach(filename, content, mimetype)
msg.attach(basename(f.name), f.read(), guess_type(f.name)[0])
f.close()
