Hi all,

I am trying to create a new menu based on a new module I am working on for Odoo v12.

I have "scaffolded" the module and using the scaffold struture.

The problem I found is that the menu structure is not shown on Odoo after module installed.

I have checked under Technical | Menu Items and they exist.

Also checked for the "action" and views and they also part of the database.

The code I used:

1. Module.py

class vehicles_brands(models.Model):
    _name='vehicles.brands'
    _description="Vehicle Brands"
    name = fields.Char(string="Brand", size=64, required=True)

2. Xml

<odoo>

  <data>   

<!-- TREE VIEW DEFINITION   -->

    <record model="ir.ui.view" id="vehicles.brands_tree_view">

      <field name="name">Vehicles</field>

      <field name="model">vehicles.brands</field>

      <field name="arch" type="xml">

        <tree>

          <field name="name"/>

        </tree>

      </field>

    </record>

    <!-- actions opening views on models -->

    <record model="ir.actions.act_window" id="vehicles.brands_action_window">

      <field name="name">Vehicle Brands</field>

      <field name="res_model">vehicles.brands</field>

      <field name="view_mode">tree,form</field>

    </record>

      <!-- Top menu item -->

    <menuitem name="Vehicles" id="vehicles.menu_root"/>

    <!-- Menu Category -->

    <menuitem name="Master Data" id="vehicles.data_menu" parent="vehicles.menu_root"/>

    <menuitem name="Brands" id="vehicles.brands_option" parent="vehicles.data_menu" action="vehicles.brands_action_window"/>

      </data>

</odoo>

I have no errors on the log and also confirm that the module is upgraded after every test.

What is wrong with this code?

PS: If I use the exact same code on Odoo 11 everything works fine.

Thank you in advance.
