Display Multiple Form and Tree View for Same Model

Problem Statement

First of all you may know the problem that what's the problem that we are facing here. For example we have a model "model.A" and we have also a tree and form view associated with that model (model.A). And we have one menu named "menuA", and this menu is visible to the only one group of users such as "Staff". 

When any user related to staff group will click on "menuA" than our above created form and tree view will be displayed to the cited user. And for that group of users we need that all the fields should be editable mode. That's working fine. 

Now the problem is what we have do when we have different group of users, and for that users we need to show some fields in readonly mode.

    <record model="ir.actions.act_window" id="parent_action_window">
        <field name="name">Parent Action Window</field>
        <field name="res_model">model.A</field>
        <field name="view_type">form</field>
        <field name="view_mode">tree,form</field>
    </record>      
 

Now that we have created new form and tree view and action window. Now we are going to split action window using "ir.actions.act_window.view". The purpose of splitting the action window is to use our newly created form and tree view.

     <record id="child_action_window_tree" model="ir.actions.act_window.view">
            <field name="view_mode">tree</field>
            <field name="view_id" ref="newly_created_tree_view_id_goes_here" />
            <field name="act_window_id" ref="parent_action_window" />
    </record>

    <record id="child_action_window_form" model="ir.actions.act_window.view">
           <field name="view_mode">form</field>
           <field name="view_id" ref="newly_created_form_view_id_goes_here" />
           <field name="act_window_id" ref="parent_action_window" />
    </record>
