I'm trying to update One2many field inside onchange method.

As documentation says I'm using update method, and not standard CRUD methods like create.

I have this piece of code:

class HrExpenseSheet(models.Model):
_inherit = "hr.expense.sheet"


@api.onchange('employee_id')
def _update_expense_ids(self):

# define variables ...

values = {
'product_id': product_id,
'name': name,
'product_uom_id': product_uom_id,
'unit_amount': unit_amount,
'quantity': quantity,
'total_amount': total_amount
}

self.update({'expense_line_ids':[(0, 0, values)]})

It almost works. I get my record added to the table but after that whole table just breaks... When this code executes couple things happen:

I'm not able to save the document because supposedly required unit_amount is not filled in - it clearly should be
When I'm trying to edit that particular line I'm not able to because it takes me to a completely new record without my data filled in (but data is present on the table view)
I'm not able to add new row because when I click the button I get error psycopg2.errors.InvalidTextRepresentation: invalid input syntax for type integer: "virtual_2509" LINE 1: ...mpany_id" = 1)) AND (("hr_expense"."id" not in ('virtual_2...

What the hell is happening. I've had the same code running on version 8.0 without problem but this does not work on 13.0.

Hi,

Try update your code like below.

    @api.onchange('employee_id')
def _update_expense_ids(self):
# define variables ...
values = [{
'product_id': product_id,
'name': name,
'product_uom_id': product_uom_id,
'unit_amount': unit_amount,
'quantity': quantity,
'total_amount': total_amount
}]
self.update({'expense_line_ids': [(6, 0, values)]})

Hope it helps

Does not work. I get an error

File "/usr/lib/python3/dist-packages/odoo/api.py", line 745, in get

value = self._data[field][record._ids[0]]

TypeError: unhashable type: 'dict'
