Hello guys, I am a newbie in OpenERP. I want ask how to change parent field value through child tree or form when child field is on change ?
For example: I have total weight field in parent and i want to decrease the total weight every time I add or edit child data. Child has product_weight field.
How can I do this? Someone please help.. Thank you..
Use onchange_event in the parent object...
specify onchange_event on your o2m lines, which will take o2m as paramter too.. then return resulting value
Thank u for your quick respons deep. Do u have any example code? for XML view and .py file. I am still confuse in return value for parent field.
