I want admins to be notified when certain objects are deleted but I also want to determine which user is performing the delete.
Is it possible?
This is the code:
# models.py
# signal to notify admins when nodes are deleted
from django.db.models.signals imp开发者_Go百科ort post_delete
from settings import DEBUG
def notify_on_delete(sender, instance, using, **kwargs):
''' Notify admins when nodes are deleted. Only for production use '''
if DEBUG:
#return False
pass
# prepare context
context = {
'node': instance,
'site': SITE
}
# notify admins that want to receive notifications
notify_admins(instance, 'email_notifications/node-deleted-admin_subject.txt', 'email_notifications/node-deleted-admin_body.txt', context, skip=False)
post_delete.connect(notify_on_delete, sender=Node)
I doubt it's possible using the built-in signals (there is no User
implicitly tied to a delete
operation, and because of Django's loose coupling the database layer doesn't deal with HttpRequest
objects). I would create my own signal which provides a user
argument and send it in whatever view the delete operation takes place, something like:
# myapp/signals.py
from django.dispatch import Signal
my_post_delete = Signal(providing_args=['instance', 'user'])
# myapp/models.py
from myapp.signals import my_post_delete
...
my_post_delete.connect(notify_on_delete, sender=Node)
# myapp/views.py
from myapp.signals import my_post_delete
...
@login_required
def my_delete_view(request, ...)
...
instance = Node.objects.get(...)
instance.delete()
my_post_delete.send(sender=Node, instance=instance, user=request.user)
