Hello,

You can set value on create and write method when you save the record.

    @api.model
    def create(self, vals):
        if vals.get('name'): 
            vals['name1'] = vals.get('name')
        your_obj = super(your_obj, self).create(vals)
        return your_obj
    
    @api.model
    def write(self, vals):
        if vals.get('name'): 
            vals['name1'] = vals.get('name')
        your_obj = super(your_obj, self).write(vals)
        return True 

Hello,

I will definetively go for a functional field (stored in base if needed).

Assuming name is a char (but it will work for any type of field)

from openerp import api

@api.depends('name')
def _mimic_name(self):
    for rec in self:
        rec.name1 = rec.name

name =  fields.Char('Name')
name1 =  fields.Char('Name1', compute='_mimic_name', store=True)

As I said, store=True is optional, it depends of wheter you want the field to be persistant in database or calculated on the fly.

Hope it helps!
