How to compare on many2one field inside Views?

Question

attrs="{'invisible':[('state_id', '=', '39')]}

and

colors="red:state_id=='39'"

Both cause errors. So I try state_id equals 'Pennsylvania' and more errors.
Then since the data is passed via JSON as an object I try state_id.id and more errors.

Hi
as i don't want you to use state_id or many2one field like that

you my suggestion is that you should use  state_id.name and give the 'name' that which country you want.

or if you still want  state_id then just do like below

attrs="{'invisible':[('state_id.id', '=', 39)]}
and
colors="red:state_id.id==39"

but you should use name because in this case you can change the name of country in user interface while you can not change ID
so it should be like

attrs="{'invisible':[('state_id.name', '
