Hi Sina,

If you add the group of that particular user in the Groups of the view, then it won't hide the view from that user. Try unlinking the group from that view using code. Then it won't reset when you upgrade base modules.

<record id="original_module.view_id" model="ir.ui.view">

    <field name="groups_id" eval="[(3,ref('your_group_id'))]"/>

</record>

Hi @Bassam and thank you for your answer,
​

But the problem is when someone as an admin user wants to give or restrict access to a specific view of a model for a user only by ui, what should he/she do? 

If there is no such ability, what is the function of "Technical Settings > User Interface > Views" and access rights there?
