Django backend -unable to use templates and substitution_data

[J0hnyBrav0]

While using EMAIL_BACKEND = 'sparkpost.django.email_backend.SparkPostEmailBackend' and creating a message like this:

 msg = EmailMultiAlternatives(
    to=to_list
  )
  msg.template = template
  msg.substitution_data = substitution_data

I've encountered several problem with missing params. After debugging I've found out that template and substitution_data are ignored. becasue they are not considered as a part of SparkPostMessage class. As result _send(self, message) in SparkPostEmailBackend is also ignoring those params.

If it's not a bug, then please provide an explanation in documentation how to use SparkPostEmailBackend and send emails using substitution data and templates.

Hi @J0hnyBrav0 thanks for reporting this. It's an issue for sure - looking into the best way to support other attributes. We basically just covered what would come across in the standard Django API, but extending it to allow other attributes makes a lot of sense.
