Hello,

I have two models. And want to show the tree view of model 2/ into the user's form view of model 1/. 

1/ Model dieu_chinh.py using one2many field:

class DieuChinh(models.Model):

    _name = "dieu.chinh"

    lstd_dieuchinh = fields.One2many('lich.su', 'thamchieu')

    thamchieu = fields.Char('Tham chiếu')

    thoigian = fields.Date('Time XYZ', default=datetime.today())

2/ Model lich_su.py using many2one field and has tree view:

class DieuChinh(models.Model):

    _name = "dieu.chinh"

    name = fields.Many2one('hr.employee', string="Test XYZ")

    thamchieu = fields.Many2one('dieu.chinh')

    thoigian = fields.Date('Time ABC', default=datetime.today())

This is code of the button to execute:

def accept(self):

    giatri_lstd = self.env['lich.su']

        gt = {

            'name': self.name.id,

            'thamchieu': self.id,

            'thoigian': self.thoigian

        }

        list_lstd_dieuchinh=[]

        for line in self.lstd_dieuchinh :

                art = {}

                art['name'] = line.name.id

                art['thamchieu'] = line.self.id

                art['thoigian'] = line.thoigian

                list_lstd_dieuchinh.append((0, 0, art))                

        gt.update({

                'thamchieu': list_lstd_dieuchinh

                    })

        giatri_lstd = giatri_lstd.create(gt)

After click the button 'accpet'. It can pass and create the records with the value from field: 'name', 'thoigian' to the model 2/'s tree view.

But it still not create the record from the field: 'thamchieu' which has a relation many2one with model 1/ . So that it cannot auto show the value in the model 2/'s tree view in the form view of model 1/'s user.

What am I doing wrong?

Please help!

Thank you!
