Hello, 

Odoo V11

The model is 'hr.payslip' I study . I am getting  an error when update field in 'hr.contract' object

I have a depends method:

@api.one

    @api.depends('line_ids')

    def _compute_cumulative_income_tax(self):

        for record in self:

            if record.line_ids:

               .... some calculations

               #error code 

                if record.cumulative_income_tax_base:

                    contract = self.env['hr.contract'].browse(record.contract_id.id)

                    if contract:

                        total = contract.varsa_devir_vergi_matrahi + temp_line_amount or 0.0

                       #After I use write method,error was occurred

                        contract.write({

                            'varsa_devir_vergi_matrahi': total

                        })
