With Scheduled Actions how can i know when current date is match with the expired date?

I have this model:

class xapiens_employee(models.Model):

_inherit = 'hr.employee'

certificate_state = fields.Selection(string="COP Status", selection=[

('draft', 'Draft'),

('expired', 'Expired')], readonly=True, default='draft')

class certificate_proficiency(models.Model):

_name = 'hr.certificate.proficiency'

_description = 'Certificate Proficiency'

_rec_name = 'certificate_name_cop'

cop_emp_id = fields.Many2one('hr.employee', string="COP Employee Name")

cop_file_name = fields.Char(String="File Name COP")

certificate_name_cop = fields.Many2one('hr.certificate.proficiency.name', string="Certificate Name")

cop_number = fields.Char('Number')

cop_issue = fields.Date('Issued')

cop_expiry = fields.Date('Expiry'))

When Date Today is match with cop_expiry, the certificate_state move to expired

Based on your description of what you are trying to do, you need to check for records where expiry date is before the date on which the job runs.

record.cop_expiry < datetime.datetime.today()
