onchange_eventapi.onchange

In the latest Odoo, usage of Api decorators (api.onchange) to perform onchange functionalities eases our job,

however I wonder how to call such onchange methods into another method, by passing those required parameters.


Let me take an example of SaleOrderLine object& its onchange method, say product_id_change

Standard definition of product_id_change is something like as follows:

@api.onchange('product_id')    
def product_id_change(self):
        
if not self.product_id:
            
    return {'domain': {'product_uom': []}}
...


Now, say in my custom module/method, am trying to call this onchange method, as it would be easier to create Sale-Order-line using those returned vals.

If it was traditional method, then I could have simply called it by passing its parameter as follows

sol_obj.product_id_change(PRODUCT_ID)

which would have returned those desired vals, however since we happen to use API decorator, I wonder how to pass those parameter.

Solution:

For those who are looking for the same.


linevals = {'product_id': PRODUCT_ID, ...} # basic needed data for the execution of Onchange-Method

line = self.env['sale.order.line'].new(linevals)        
line.product_id_change()
linevals = line._convert_to_write({name: line[name] for name in line._cache})
