Dynamic Django Mail Configuration

Question

I don't want to use email configuration fields in setting.py, i want to put them in to a model.

class Configuration(models.Model):
    email_use_tls = models.BooleanField(_(u'EMAIL_USE_TLS'),default=True)
    email_host = models.CharField(_(u'EMAIL_HOST'),max_length=1024)
    email_host_user = models.CharField(_(u'EMAIL_HOST_USER'),max_length=255)
    email_host_password = models.CharField(_(u'EMAIL_HOST_PASSWORD'),max_length=255)
    email_port = models.PositiveSmallIntegerField(_(u'EMAIL_PORT'),default=587)
    ....

What is the best practice to configure django.core.mail.send_mail behaviour? Should i copy send_mail code to my project? Thats not what i want.

Answer 1

Very interesting question. It seems like this is already implemented in EmailMessage class.

First you need to configure email backend

from django.core.mail import EmailMessage
from django.core.mail.backends.smtp import EmailBackend


config = Configuration.objects.get(**lookup_kwargs)

backend = EmailBackend(host=config.host, port=congig.port, username=config.username, 
                       password=config.password, use_tls=config.use_tls, fail_silently=config.fail_silently)

Then just pass connection to EmailMessage

email = EmailMessage(subject='subj', body='body', from_email=from_email, to=to, 
             connection=backend)

Then send email :)

email.send()

Ofc if you want html or file attachments use EmailMultiAlternatives instead

Answer 2

There is little error in the answer above (Andrey Nelubin's answer). No need to call get_connection(backend=backend). You should pass backend to the EmailMessage constructor, like this:

backend = EmailBackend(host=config.host, port=congig.port, username=config.username, 
                               password=config.password, use_tls=config.use_tls, fail_silently=config.fail_silently)
email = EmailMessage(subject='subj', body='body', from_email=from_email, to=to, 
                 connection=backend)

I can not add comment that answer and dicided to post new one. Please someone who have permissions move it there or correct the answer.
