Hi Fred,

hello_msg = fields.Char(string="hello", compute='_test_hello', store=True)

update hello_msg field as storable, then compute function triggers only when the dependent field changes.

Regards

@Rinkal thanks for your reply. However, I've tried doing it and it still triggered every time I entered the list view.

A couple more questions:

* doesn't your example iterate through all records anyway? Is there a way to target the single record that changes, instead of iterating through the self recordset?

* what is the point of  compute='_test_hello' on my original example? If we are manually assigning the a value to rec.hello_msg inside the function, we could very well assign values to other attributes, which makes me think that the compute field is useless? 

Hello,

You can use onchange() method instead of the compute method.

@api.onchange("first_name")
def _test_hello_based_on_change(self):
    for rec in self:
        rec.hello_msg= ''
        rec.hello_msg= 'Hi, ' + rec.name
