It is simple possible using define _constraints for that field. In that you can define python function to manage validation. So, you can manage as you want llike value shouldn't "0" or value must follow any special pattern. You can define your validation as like below.

_constraints = [ _check_function, "Message of wrong entry", ['field1','field2', ... ] ]

def _chech_function(self, cr, uid, ids, context=None):

    //Your code to manage entered record.

    //You can return True to allow entered record or you can return False to deny entered record.


I hope this will help you.

this code fully work..give up + one vote

Thank you very much for your answer

When I issue a payment for an invoice (Customer invoice for exemple), the system accepts zero as payement value.This seems illogical to me ,I think this had to be managed by core functionnalities. and not by adding some python code..

Am new to Odoo, but I was sure that this kind of validation rules would be implemented easily (or natively)...

Thanks in advance for your clarifications.
