Django safedelete
What is it ?
For various reasons, you may want to avoid deleting objects from your database.
This Django application provides a model mixin, that allows you to transparently retrieve or delete your objects, without having them deleted from your database.
- You can choose what happens when you delete an object :
it can be masked from your database (soft delete)
it can be normally deleted (hard delete)
it can be hard-deleted, but if its deletion would delete other objects, it will only be masked
it can be never deleted or masked from your database (no delete, use with caution)
Example
# Models
# We create a new mixin, with the given policy : Objects will be hard-deleted, or soft deleted if other objects would have been deleted too.
SafeDeleteMixin = safedelete_mixin_factory(HARD_DELETE_NOCASCADE)
class Article(SafeDeleteMixin):
name = models.CharField(max_length=100)
class Order(SafeDeleteMixin):
name = models.CharField(max_length=100)
articles = models.ManyToManyField(Article)
# Example of use
>>> article1 = Article(name='article1')
>>> article1.save()
>>> article2 = Article(name='article2')
>>> article2.save()
>>> order = Order(name='order')
>>> order.save()
>>> order.articles.add(article1)
# This article will be masked, but not deleted from the database as it is still referenced in an order.
>>> article1.delete()
# This article will be deleted from the database.
>>> article2.delete()Compatibilities
