Abstraction to logical/soft delete in django models
Project description
Django Soft Delete
Django Soft Delete gives Django models the ability to soft delete(logical delete). it also gives the ability to restore or undelete soft-deleted instances.
Basic usage
- Clone this repo and then
$pip install django-soft-delete
- Add softdelete model to INSTALLED_APPS
- Inherit all models you want to have this functionality from softdelete.models.SoftDeleteModel
>>> MyModel.objects.create(name='Anakin')
>>> MyModel.objects.create(name='Luke')
>>> MyModel.objects.create(name='Yoda')
>>> luke = MyModel.objecs.filter(name='Luke')
>>> MyModel.objecs.filter(name='Luke').delete()
>>> MyModel.objects.count()
2
>>> MyModel.raw_objects.count()
3
>>> MyModel.objects.get(id=luke.id).undelete()
>>> MyModel.objects.count()
3
Samples
from softdelete.models import SoftDeleteModel
class MyModel(SoftDeleteModel):
name = models.CharField(max_length=30)
You can also use the SoftDelete django manager to extends your custom manager funcionalities. Do it like so:
#my_model_manager.py
from softdelete.managers import SoftDeleteManager
class MyModelManager(SoftDeleteManager):
def create_john_smith(self):
self.model.objects.create(name='Jonh Smith')
#my_model.py
from django.db import models
from my_model_manager import MyModelManager
class MyModel(SoftDeleteModel):
name = models.CharField(max_length=30)
objects = models.Manager()
my_manager = MyModelManager()
It's possible to have access to delete instances through an alternative manager raw_objects
for inst in MyModel.raw_objects.all():
print inst.name
