Project Description

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()
