I need to create a field with a value suggested by the program according to the last back label generated for the selected series.
I have this:
back_label_from = fields.Integer(string="Back Label From", default=lambda self: self._get_default_back_label())
@api.model def _get_default_back_label(self): back_label_id = self.env['back.label'].search([('back_label_from')]) return back_label_id.id
I don't know exactly what to put in the function (
def _get_default_back_label(self):
)
Hi,
We can retrieve the last created record in the model “back.label” using search method by specifying the order and using limit parameter.
back_label_id = self.env['back.label'].search([("domain")], limit=1, order='id desc')Hence you will get the last created record object in back_label_id.After getting the object you can assign the value accordingly.If you have any domain used for the search operation please specify the domain in the brackets also.
Eg:
def _get_default_back_label(self)
back_label_id = self.env['back.label'].search([("domain")], limit=1, order='id desc')
return back_label_id
