I'm customizing a module for hr.payroll that registers payment for the payslip, starting with a Register Payment wizard that then passes the data to account.payment when validated for the check to be printed. All other fields like memo and partner_id pass as expected, but doesn't fill anything in my one2many field, which is trying to pull the Name and Amount values from hr.payslip line_ids. 

My One2Many field:

pay_line_ids = fields.One2many('pay.line.ids', 'payline_id', string='Paylines', readonly=False, copy=True)

class PayLineIds(models.Model):

    _name = 'pay.line.ids'

    _description = 'Payslip Payment Lines'

    payline_id = fields.Many2one('account.payment', string='Pay Slip', required=False)

    name = fields.Char(string='Name', required=False)

    amount = fields.Float(digits=dp.get_precision('Payroll'))

I've attempted two methods. Any help is appreciated.

First is setting onchange

    @api.onchange('pay_line_ids')

    def _onchange_lines(self):

        context = dict(self._context or {})

        active_ids = context.get('active_ids', [])

        payslip = self.env['hr.payslip'].browse(active_ids)

        ids = []

        for line in payslip.line_ids:

            lines = {'name':line.name,'amount':line.amount}

            ids.append(lines)

        self.pay_line_ids = [(6,0,ids)]
