[Python] Odoo 16: payment_state Not Updating in tenancy.rent.schedule After Payment

I’m trying to update the tenancy.rent.schedule records when an invoice is fully or partially paid in Odoo 16. I have overridden the action_post method in account.payment to check if the invitation is paid and update the paid and move_check fields in the rent schedule.

However, howver the issue is that rent.invc_id.payment_state does not fetch the latest state even after making the payment. It still shows not_paid even when the invitation is marked as paid.

Here is my code:

class AccountPayment(models.Model):
_inherit = 'account.payment'

def action_post(self)
"""
Override to update rent schedules when an invoice is fully or partially paid.
"""
res = super().action_post()
print("Context in action_post:", self.env.context)

if self.env.context.get('asset') or self.env.context.get('openinvoice'):
print(" 'openinvoice' is in the context!")
tenancy = self.env['property.tenancy']
active_id = self.env.context.get('active_id')
print('active id :', active_id)

if not active_id:
return res # No active tenancy, skip execution

tenancy_record = tenancy.browse(active_id)
print('tenancy_record :', tenancy_record)
if tenancy_record:
rent_schedules = self.env['tenancy.rent.schedule'].search(
[('invc_id', '=', tenancy_record.id)]
)
print('rent schedule : ', rent_schedules)

for rent in rent_schedules:
print('Invoice: ', rent.invc_id)
print('rent.invc_id.payment_state :', rent.invc_id.payment_state)

if rent.invc_id.payment_state == 'paid':
rent.paid = True
rent.move_check = True

# Update hanging amount (pen_amt)
rent.pen_amt = rent.invc_id.amount_residual

return res


based on the payment_state

rent.paid = True
rent.move_check = True


these should be True based on the " if rent.invc_id.payment_state == 'paid':
