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 = model         


        

Answer 1

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.

Answer 2

You should create an object from EmailBackend:

I have been an answer in the previous stack overflow post.

Answer 3

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 4

I've used this method for a few years and love it. I've just published a package (django-des) to accomplish this using the methods in the other answers here.

This package installs a model (DynamicEmailConfiguration) and uses django-solo to give you a nice editing experience in the Django admin. It then provides an email backend you can use that will pull settings from that model in a similar way to what Andrey Nelubin recommended. It also gives you a nice little test email button at the top right of the Django Admin Panel.

To install it:

• Install Django Dynamic Email Settings:

  $ pip install django-des
  

• Add it to your `INSTALLED_APPS`:

  INSTALLED_APPS = (
      ...
      'django_des',
      ...
  )
  

• Add the dynamic email configuration email backend to settings.py

  EMAIL_BACKEND = 'django_des.backends.ConfiguredEmailBackend'
  

• To enable test email support, add Django DES's URL patterns:

  from django_des import urls as django_des_urls
  
  urlpatterns = [
      ...
      url(r'^django-des/', include(django_des_urls)),
  ]
  

Now you can visit 127.0.0.1:8000/admin/django_des/dynamicemailconfiguration/ and configure your email settings. You can send a test email from there too.

Once this is all done, you can use send_mail normally.
