pip install django-paranoid

How to start

1.- Add to django-paranoid in the django apps:

INSTALLED_APPS = [
    'django.contrib.admin',
  'django.contrib.auth',
        ...
  'django-paranoid'
  ...
]

2.- Extends ParanoidModel in the model to use:

from django_paranoid.models import ParanoidModel

class MyModel(ParanoidModel):
    field = models.CharField(max_length=20)

3.- Add to django-admin:

from django_paranoid.admin import ParanoidAdmin

class MyModelAdmin(ParanoidAdmin):
    pass
  ...
admin.site.register(MyModel, MyModelAdmin)

Soft Delete

m = MyModel.objects.last()
m.delete()

This only applies soft delete, so the record will remain in the database, but it will not be visible for normal queries:

m = MyModel.objects.last()
m

Now the record has a deleted_at field and if do you want show the delete record you could using ‘objects_with_deleted’:

m = MyMode.objects_with_deleted.last()
m
<MyModel: name>
m.deleted_at
datetime.datetime(2019, 8, 10, 6, 16, 44, 633727, tzinfo=<UTC>)

Hard Delete

If do you want to delete record from DB, you only should using True param:

m = Mymodel.objects.last()
m.delete(True)
