How to Pass value while raising exception

Question

I have a scenario where I am raising exception in some conditions. But I need to make some fields 'Blank' or pass value '0' if the exception occurs.
I am using @api.onchange method and have tried following ways but none of them worked:
1.
self.holiday_status_id = False
raise except_orm('No Joining Date!', 'There is no joining date defined for this employee') 2.
res = {'warning':{'title':_('No Joining Date!'),
'message':_('There is no joining date defined for this employee')},
'value':{'holiday_s

Ok I got this. As I am using onchange method I have to use the 'Warning' like this:

self.holiday_status_id = False
return {'warning': {
'title': "Warning",
'message': "There is no joining date defined for this employee",
}
}

Hello, use this:
from openerp.exceptions import except_orm, Warning, RedirectWarning raise except_orm('Warning', warning_message)
raise Warning(warning_message)
raise RedirectWarning(warning_message, True, _('continue'))
