Hello Dep,


Try this :-


from openerp import models, fields, api, _

from openerp.exceptions import UserError

@api.model

def create(self, vals):

    result = super(crm_lead, self).create(vals)

    if not result.crm_lead_ids:

        raise UserError(_('You Can not Add Instructor as a attendee.')

    return result


Hope it will works for you.

Thanks,

also self.crm_lead_ids: this one and result.crm_lead_ids: this are same right?

Hello Dep, create method is in the base so if we access any existing method, we must call super for it.

Dep,
Infact Jignesh method is correct, but if you still want to minimize the execution then we can just check,
if not vals.get('crm_lead_ids', False):
raise UserError(_('Your message.'),
before calling super,
