I am trying to delete some record from database not the current record, and i got error like this:

result = [method(rec, *args, **kwargs) for rec in self] 

return new_api(self, *args, **kwargs)

ValueError: "unlink() takes exactly 1 argument (2 given)" while evaluating

and here my code:

class demo_demo(models.Model):

_name = 'demo.demo'

...

@api.multi

def unlink(self):

return super(demo_demo, self).unlink()

@api.one

def _delete_from_db(self):

# Search data in database for current model

find_id = self.search([('name', '=', 'demo')]) # result demo.demo(1,)

self.unlink(find_id.id)

Thanks.
