Hi, 

This is an example:



class ModelA(models.Model):
         _name = 'model.A'

         type = fields.Boolean(string='Type')


class ModelB(models.Model):
         _name = 'model.B'

         type = fields.Selection([('1', 'One'),('2', 'Two')])

I want when i select 1 in the selection option in model B to change the default value of field 'type' in model A to true, and 2 to false

How can i do that

Thanks

Check out the related fields. They are fields that obtain value based on another. The advantage is that you save coding the onchange event.

Hi, 

Both models should be linked. So we'll add a M2O field in model B like this: 

a_id = fields.Many2one('model.A')

Then consider adding a ochange like this: 

@api.onchange('type'):
def onchange_type(self):
if self.type == ' 1':
    self.a_id.type = True
else:
​    self.a_id.type = False

Hope this helps.
