I need to run the following scheduled action:

​odoo
    record id="ir_cron_renovation" model="ir.cron"
        field name="name">Verificar vigencia de suscripciones /field
        field name="model_id" ref="model_sale_subscription"/
        field name="state"  code  /field
        field name="code"  model.check_espiry()  /field
        field name="interval_number"  1  /field
        field name="interval_type"  days  /field
        field name="numbercall"  -1  /field
        field name="doall" eval="True"/
        field name="active" eval="True"/
    record
odoo

This is my function:

class Renovation(models.Model):
​_inherit = 'sale.subscription'

​def check_espiry(self):

​#my code here

Manually if run but not automatically. The error is this :
