odoo12根據用戶組隱藏按鈕

直接在視圖裏，繼承過來改寫一下就好了，這裏是form視圖，隱藏了創建，編輯的按鈕。

 <record model="ir.ui.view" id="view_material_groups_section">
            <field name="name">根據用戶組隱藏按鈕</field>
            <field name="model">warehouse.material</field>
            <field name="inherit_id" ref="warehouse.warehouse_material_form"/>
            <field name="groups_id" eval="[(4,ref('warehouse.user_group'))]"/>
            <field name="arch" type="xml">
                <xpath expr="/form" position="attributes">
                    <attribute name="create">false</attribute>
                    <attribute name="edit">false</attribute>
                </xpath>
            </field>
        </record>
