Django - many to many with post_save gridlock
===

I want to send out an email when a model instance is saved. To do this I listen out for the post_save signal:


    #models.py
    @receiver(post_save, sender=MyModel, dispatch_uid="something")
    def send_email(sender, **kwargs):
        instance = kwargs['instance']
        email = ModelsEmailMessage(instance)  
        email.send()

In my view I process the form and append subscribers to the object:

    #views.py
    object = form.save()
    object.subscribers.add(*users)

My problem is that the form save triggers the post_save signal before the users have been added.

But if I do this:

    object = form.save(commit=False)

then I can't add m2m instances to an object that has no id.

Heyulp!
