Django Admin sending email after post

Question

So I'm familiar with sending emails using django, but I'd want to send an email to all those that subscribed to my newsletter if I were to use the admin panel instead of the one I have on the site itself. How would I go about doing this? For my current view on the user site version, it is something like:

    def form_valid(self, form):
        message = 'A new article has been released...'
        subject = 'New Article!'
        to = Email.objects.values_list('email', flat=True).distinct()
        from_email = settings.EMAIL_HOST_USER
        send_mail(subject, message, from_email, to, fail_silently=True)

        return super().form_valid(form)

Answer 1

Using django signals will do it via admin or via site doesnt matter.

You can create a signal in blog post view like this:

@receiver(post_save, sender=BlogPost)
def send_mail_to_subs(sender, instance, created, **kwargs):
    if created:
        for subs in instance.author.subscribed.all():
            send_mail(
                f'New Post from {instance.author}',
                f'Title: {instance.post_title}',
                'youremail',
                [subs.email],
            )

Good coding:)
