Hi everybody,
I'm trying to modify the form view of sale order to add two columns automaticaly filled when the product is selected with the informations of two fields i've added in the product creation. I've identified into the sale.order.form view that there is an on change option linked with the product_id_change function but i want to know where is the python file containing this function. Thanks for youre help.
Hi,
The onchange method product_id_change is defined in sale module in sale.py file's sale.order.line model.

Yes i know i've already find this method, the problem is that i want to add into this method the two parameters i've added into the product.product model to return them into the result of the product_id_change method and permit to fill automatically two colums i've added to the sale.order.line.
Which are the fields and what are their types? You can add them to the result dictionary in the above method.
this is two fields i've created named x_departement and x_support, the type of the two fields is Many2one and they are each related with two models (x_departement_model and x_support_model) that i've created. Each of the two models are containing one char field.
Did you inherit the sale.order model. If yes write the product_id_change function in your inherited model and in the product_id_change function's result dictionary add the two new fields and their value.
Why do i have to inherit the sale.order model? If i only modify the sale.order.view adding two columns at the sale order line and addind my two new product fields as parameters of the product_id_change function and into the result dictionnary, this isn't good?
i write you the steps i think i had to make: -create two new fields into the sale.order.line model with type many2one linked with the two fields i've created into the product.product model -add these two new fields as columns into the sale order view xml and into the onchange of the field product_id -add the two fields as parameters of the product_id_change function of the sale.py and retrieve their value to return it into the result dictionnary
You have two models x_departement_model and x_support_model and you have added two fields in sale order model named x_departement and x_support. You can directly add the fields to the product_id_change method in sale.order model without inheriting. But it is not recommended because if you need to migrate to a new openerp version it will cause problems.
oki i have understood the problem, i'm going to try what you've said and will come later to share the result. Thanks for your help
