I'm working on code refactoring of django project which was like 4 years old and came across a syntax which confused me.

They passed a boolean parameter `False` to django ORM like `object.delete(False)`.

I checked the docs for `delete()` function in django ORM. But couldn't find `False` parameter to it.

And there is no method overriding in Django Model for `delete()` method.

What is this `False` parameter for?

**`Django version: 1.11.29`**
