To get Python Django Admin to delete files when I remove an object from the database/model, we can use the delete method.
For instance, we write
class MyModel(models.Model):
file = models.FileField()
#...
from django.db.models.signals import pre_delete
from django.dispatch.dispatcher import receiver
@receiver(pre_delete, sender=MyModel)
def mymodel_delete(sender, instance, **kwargs):
instance.file.delete(False)
to add the mymodel_delete function and we apply the receiver decorator on it.
We call receiver with pre_delete to run mymodel_delete before deleting the model entry.
In mymodel_delete, we call instance.file.delete with False to delete the file without saving to the model.
