Hi,

I have created a function to be called by multiple class within the same file(.py)

But How?

The following is my file.py

------------------------

    def holiday(lookup_date):
        # check holidays
        
        hday_credit_rate = 0
        
        *****Error below calling the table outside the class****** 
        holidays = env['hr.company.holidays'].sudo().search([('date', '=',                     lookup_date)])

        if holidays:
            holiday_rate = env['hr.holiday.rate'].sudo().search([('id', '=',                             holidays.holiday_rate_id.id)])
            hday_credit_rate = holidays.credited_rate
        
        return hday_credit_rate


class dtr(models.Model):
 _name = 'hr.dtr'
_inherit = ['mail.thread', 'mail.activity.mixin']
 _description = "Daily Time Record"

employee_id = fields.Many2one('hr.employee', string='Employee', required=True)

********start to call the table outside the class 
holiday_credit = holiday('2020/07/03')
