how to resolve error KeyError: 'employee_id' - python-2.7

Question

i'm using odoo 8 and i have develop a custom module for biometric device and it shows error
userHasUserDevice = biometric_user_obj.search([('employee_id', '=', int(values['employee_id'])),
KeyError: 'employee_id'
i tried to fix the problem but it always display the same problem. Any idea for help please ?

Answer 1

Please check values of create() method, employee_id is not available and you are trying to get employee_id from values.
You should check that employee_id is available in values or not as like following :
if 'employee_id' in values :
userHasUserDevice = biometric_user_obj.search([('employee_id', '=', int(values['employee_id'])),
('biometric_device', '=', int(values['biometric_device']))])
