How to execute constraints validations in one2many field when it is being saved, not when the parent is saved?
I have an object with some _sql_constraints and _constraints. This object is a column of a "parent" object, an one2many field in parent class. I need to execute those constraints and _sql_constraints validations when I save the "child" object, not at the moment of saving parent object. Please any help will be welcome, I need a solution as soon as posible....thanks in advanced!!
pd: Sorry my English.
the point is that child object is not saved until parent is saved. In order to achieve desired behaviour, you might:
1. Instead of constraints, introduce a check as onchange in validated fields. E.g.
from openerp import exceptions
for object in self:
if object.field_1 > object.field_2:
raise exceptions.Warning('NOT GOOD!')
Have a look for a similar example in the 'sale' module, when a partner is changed.
2. Force save of a parent object, when child is saved. It ontradicts Odoo logic! But in the onchange you may add some 'write' function, which launch check of constraints.
