[V13]Editing a related field

Question

I've defined a related field like
vat= fields.Char(related='partner_id.vat', readonly="False")
then in form definition
<field name="vat" force_save="True" readonly="False"/>
When I enter edit mode on the form, I can modify the value, but when I hit "save", the value goes back to the old value.
Which is the correct way to do it ?

Hi..,
By default, the value of the related field is not stored in the database. If you want to store it you need to define attribute  /store/  with value True.

class YourModel(models.Model):
_name = 'your.model'
partner_id = fields.Many2one('res.partner')
vat= fields.Char(related='partner_id.vat', store="True")

Hi
Please try the following code,
vat= fields.Char(related='partner_id.vat',store=True,readonly=False) To store the edited value in a related field, you need to store it.
Hope it helps
