When I create a compute field in odoo i Got below error,

Error:

If I use automated action it work perfectly

Hii JNZ,


You cannot raise warnings from UI while computing the field as exception modules(Warnings,UserError, ValidationError) are not predefined there.
The only predefined modules/variables are:
self (the set of records to compute)
datetime (Python module)
dateutil (Python module)
time (Python module)

->Instead of using compute or automated action,you can use user defined constraints to raise exceptions from your code.
You have to import the exception module and then write your function.
Here is the code:

from odoo.exceptions import ValidationError

@api.constrains('date_time')
def _check_date_time(self):
for rec in self:
if rec.date_time > datetime.datetime.now():
raise ValidationError(_(
"Your Message."
))
