how to on_change

Question

Can someone provide a simple example of how to use on_change ?

I want that when a user changes the value of many2one field, the on_change method would fetch values of the parent object and populate other fields with them.

I areally appreciate your help.

Hi Abdullah, [1]

First of all you decide the field to give on-change then add *on_change* attribute to that field

Then define onchange function in .py file:-

def onchange_demo_field(self, cr, uid, ids, product_id, product_qty=0, context=None):
res = {}

function body
return res
