Default value editable on field

Question

Hi,
I would like to know how can I achieve this
I have a field called demofield that has the value 10 for example
And I would like that my field demofield2 has as default the value of the first demofield but it can be editable.
I have tried with  @api.onchange but always set the value of demofield2 as demofield and I can't change it.
Thank you for your help

You have to set your demofield2 as a computed field;
demofield2 = fields.Float(compute='_compute_demofield2', store=True) @api.depends('demofield')
def _compute_demofield2(self):
self.demofield2 = self.demofield
The store=True parameter is very important to make the field editable.
