You can set the access rights for that model, by giving only the read access to users right? Otherwise you need to inherit the view in your custom module and using 'attrs' attribute, set the required fields as readonly

Thank you Akhil. I was trying to avoid marking each field with "attrs" since there are many; I'm trying overriding fields_view_get but the custom fields are not accessible from within the method.

Hi,, You want to make a field read-only and its value depends on another field,, am I correct???

Hi Baiju, I need to make the WHOLE record readonly, according to a value in one of the fields. And I would prefer to avoid overriding each edit form.

any updates? I am looking solution for the same case.
