Let's say I have
class A(models.Model):
_name = "A"
field_a = fields.Many2one('B')
class B(models.Model):
_name = "B"
field_b = fields.Char()
On a form which model is A I need to render field_b. I tried like this:
<field name="field_a.field_b" /> but with no luck
What is the correct way to do this?
You can't write in this format in xml field_a.field_b
You can use related fields to achieve your goal
example
class A(models.Model):
_name = "A"
field_a = fields.Many2one('B')
field_b_in_a = fields.Char(related='field_a.field_b')
and in xml add
<field name="field_b_in_a" />
