Hello,

I have 3 models.

Model_a.py:

fila = fields.one2many('model.c', 'keya')

kn_b = fields.many2one('model.b')


Model_b.py:

filb = fields.one2many('model.c', 'keyb')

reference = fields.Char('Reference')

date = fields.Date('Date')


Model_c.py:

filcb = fields.many2one('model.b')


I will create records in model b. In this model b, there is a button is there. On clicking on that button I need to copy all values (all records) of filb field to fila field of model a .

I'd tried with this code:

def accept(self):

for record in self:

            filb_values = [(0, 0, {'reference': line.reference, 'date': line.date}) for line in record.filb]

            vals = {'fila': filb_values}

self.env["model.a"].write(vals)

return True


After click a button 'Accept'. It still not show all records ( in tree view notebook of model b) in one2many tree view notebook of model a.


Please help!

Thank you!

Finally, I'd solved my issue. Just add the line like this:

.....

filab = self.env["model.a"].search([])

filab = filab.write(vals)

return True


And it works fine after clicking the button: 'accept'.
