Sending emails, models or views?

[Marc Aymerich]

Yep,
I'm more or less convinced that the logic needed for sending an email
should go into models. But what about the action (method call) of
sending the email? what layer should be responsible for triggering an
email notification? models or views? This is something I keep
wondering myself for a long time ...

for example, imagine we have a simple Ticket model with two methods,
update() and notify_owner()

class Ticket(models.Model):
def update(self):
self.updated_on = now()
self.save()

def notify_owner(self, msg):
send_mail(self.owner, msg)


now we want to notify the owner each time a Ticket is updated, shall
we include a self.notify_owner('updated!') call on the update()
method, so we make sure of that? or maybe it is better to do this on
the view each time ticket.update() is called?

There are some pros and cons,
In the views we have access to the request object which some times is
handy because we need some request info to include on the mail.
Including the call into the model we make sure that each time we will
send an email notification and DRY is good, but is this behavior
correct? maybe we only want to notify under certain circumstances...

So anyone has thought about this? any rule of thumb? maybe it totally
depends on the use case? does this question even make sense? :)

Thanks for your answers!

Coincidentally, I debated this with myself this afternoon. At the end,
i put my notify_by_email method in models.py because I didn't need the
request object and it kinda "felt at home" there. However, I'd have put
it in my view if I needed the request object so personally, it depends
on use case.
