class test_line(models.Model)
_name='test.line'
name = fields.Char('name')
test_id = fields.Char('Test')
t = fields.Char('T')
class test_parent(models.Model):
test_line_id = fields.One2many('test.line','test_id')
name = fields.Char('name')
** How to return field name in Class test.line to field name in Class test_parent
How i can to solve this Please Help
Thanks
Hi, I am not allowed to comment under your post.
Every One2many field requires a Many2one field.
Model 'parent' has a One2many, then Model 'child' must have a Many2one responding to it.
class TestParent(models.Model):
_name = 'test.parent'
name = fields.Char('Name')
child_id = fields.One2many('test.child', 'parent_id')
class TestChild(models.Model):
_name = 'test.child'
name = fields.Char('Name')
parent_id = fields.Many2one('test.parent', 'Parent ID')
BOLD text is the key that properly relates two models.
For instance, in parent, you can have tree views, then the child is what's available as columns in that tree view.

1. Use the live chat to ask your questions.
2. The operator answers within a few minutes.
first learn how to correctly do an inverse relation. You also are missing the _name for your parrent model test_id = fields.Many2one('_name value').
Go and learn the basics about relations and models.
def get_name(self):
return self.test_id.name
If you want as a field you can use a relation field. Go read the official documentation and start doing the examples.
