HI Tanzilul,

You can inherit the website template and give a condition to display your field,

eg t-if = "not public visitor[portal group or your custom group]" t-esc="yourfield"

hence the public users cant see the field,

if you provide your code here I can answer you by code

Tanzil,

I tried to override the existing access right

https://www.odoo.com/forum/help-1/question/how-to-make-a-model-is-fully-public-108950

But I could not find it.

Then I directly changed under the settings menu

Activate developer mode
Settings -> Technical -> Database Structure -> model -> res.partner -> Access rights

Thanks !

Odoo provides 3 kinds/levels of Security access to control the data.

1. Object Access Control

2. Record Rules

3. Field Access

To Control displaying of records/data, you need to use Security Record Rules.

Similarly to control couple of fields on the view, you need to use Groups to define Field Access in the XML Views.

Permissions which are defined in the CSV, will merely act as Object Permission and certainly not on the data/record present in the object.
