how to delete one2many if many2one is deleted

Question

Hello, i have 2 classes:

class ModelA:
_name = "model.a"

​first_field = fields.One2many(
​	​comodel_name="model.b",
​	​inverse_name="second_field",
​	​ondelete="cascade"
​	​)

class ModelB:
​_name = "model.b"

​second_field = fields.Many2one(
​	​comodel_name="model.a",
​	​ondelete="cascade"
​	​)

If one2many is deleted, many2one will also be deleted. However, if many2one is deleted, the data in one2many still remains. How to delete the one2many if many2one has been deleted?

Hi,
This is not a usual behaviour, but you can achieve it by supering the unlink function.
def unlink(self) is the function that works when deleting a record, so you could call that function and super it and make necessary changes.
Regards
