In that case, you can override this method to raise custom error message when the corresponding conditions are met. You have the uid of the user that called the write method, so it must be enough to achieve the desired effect. | 1 | 0 | 0 | In Odoo 8, I added an ir.rule to a model that restricts write access for certain users. I would like to personalize the error message restricted user get after clicking 'Save'. I can't just modify the translation with _() because the new message must be specific to that model.

D, M, s = [x[0] for x in n]
This effectively loops through the list of tuples taking the first item and resulting in a list that now looks like: [100, 300, 500]
This is then unpacked in: D, M, s

by synonym I also mean same words written differently like :

or dog and hound
