Hi,

Here is my code.... in DTR.PY

from odoo.exceptions import UserError

** function outside class and opening holiday table belong to other module

def holiday():

      holiday_obj = self.env['hr.holiday']   <--------- i got a error here! when i erase the "self." since it was

                                                                                not in a class but how can the ENV be evaluated?

      return holiday_obj

class Dtr(models.Model):

        holiday_obj = holiday()
