Just an example: An employee have some private information. An employee can see his own private information. But should not see other employee private information. In that case we can use attrs = "{'invisible': []}". It can invisible from view. But it's not secure. it's actually eye wash. if we inspect browser & go to Network-> XHR-> read-> JSON response, got the other employee private information. it's the problem of odoo security. there have any other solution for form view of odoo. It'll be helpful for us.
