Get all related Django model objects

Question

How can I get a list of all the model objects that have a ForeignKey pointing to an object? (Something like the delete confirmation page in the Django admin before DELETE C

@digitalPBK was close... here is probably what you are looking for using Django's built-in stuff that is used in Django admin for displaying related objects during deletion

from django.contrib.admin.utils import NestedObjects
collector = NestedObjects(using="default") #database name
collector.collect([objective]) #list of objects. single one won't do
print(collector.data)

this allows you to create what the Django admin displays - the related objects to be deleted.
