Soft delete and DELETE CASCADE

[foucdeg]

I have this model:

class MyParent(models.Model):
    # whatever

class MyModel(SoftDeleteModel):
    parent = models.ForeignKey(MyParent, on_delete=models.CASCADE)

What happens if I delete a Parent which has children MyModel? Does the child get physically deleted, or soft deleted and the foreign key set NULL?

Hi, @foucdeg !

Currently, the cascade deletion is not changed and it works as the Django standard functionality.

Soft-deletion works only with the models, you specifically inherit with the SoftDeleteModel class. This library overrides the model's delete method and the model queryset's delete method.

So the child does get physically deleted. It's probably a good thing to document.

Thanks! It's a good remark. I have documented it already.

How about this?

class MyParent(SoftDeleteModel):
    # whatever

class MyModel(SoftDeleteModel):
    parent = models.ForeignKey(MyParent, on_delete=models.CASCADE)

I tried to soft delete the parent yet the child model is not soft deleted. How to soft delete the child model by soft deleting the parent ?

I'm facing the same problem here, should I use the Signal and handle it myself?
