python - External ID not found in the system: training.training_odoo_menu

Question

so i'm in a training, and i got task to create some custom module, it works well when the code still like this

models.py

class Kursus(models.Model):
    _name = 'training.kursus'
     
    name = fields.Char(string="Judul", required=True)
    description = fields.Text()

class Sesi(models.Model):
    _name = 'training.sesi'
     
    name = fields.Char(required=True)
    start_date = fields.Date()
    duration = fields.Float(digits=(6, 2), help="Durasi Hari")
    seats = fields.Integer(string="Jumlah Kursi")
    instructor_id = fields.Many2one('res.partner', string="Instruktur")

and the view.xml is like this :

<odoo>
    <data>
    <!-- ### Membuat Tampilan Tree/List Sesi ### -->
     
    <record model="ir.ui.view" id="sesi_tree_view">
        <field name="name">training.sesi.tree</field>
        <field name="model">training.sesi</field>
        <field name="arch" type="xml">
            <tree string="Sesi List">
                <field name="name"/>
                <field name="start_date"/>
                <field name="duration"/>
                <field name="seats"/>
                <field name="instructor_id"/>      
            </tree>
        </field>
    </record>
     
     
    <!-- ### Membuat Tampilan Form Sesi ### -->
         
    <record model="ir.ui.view" id="sesi_form_view">
        <field name="name">training.sesi.form</field>
        <field name="model">training.sesi</field>
        <field name="arch" type="xml">
            <form string="Sesi Form">
                <sheet>
                    <group>
                        <field name="name"/>
                        <field name="start_date"/>
                        <field name="duration"/>
                        <field name="seats"/>
                        <field name="instructor_id"/>
                    </group>
                </sheet>
            </form>
        </field>
    </record>
     
     
    <!-- ### Membuat Action/Event Object Sesi ### -->
     
    <record model="ir.actions.act_window" id="sesi_list_action">
        <field name="name">Sesi</field>
        <field name="res_model">training.sesi</field>
        <field name="view_type">form</field>
        <field name="view_mode">tree,form</field>
    </record>
     
     
    <!-- ### Membuat Sub Menu Sesi ### -->
     
    <menuitem id="sesi_menu" name="Sesi" parent="training_odoo_menu" action="sesi_list_action"/>
    
    </data>
    </odoo>

but when i updated the models.py into like this, like my code below, it gain an error, the error is on the last of this question

    class Kursus(models.Model):
        _name = 'training.kursus'
     
        name = fields.Char(string="Judul", required=True)
        description = fields.Text()
        session_ids = fields.One2many('training.sesi', 'course_id', string="Sesi")
    
    class Sesi(models.Model):
        _name = 'training.sesi'
         
        name = fields.Char(required=True)
        start_date = fields.Date()
        duration = fields.Float(digits=(6, 2), help="Durasi Hari")
        seats = fields.Integer(string="Jumlah Kursi")
        instructor_id = fields.Many2one('res.partner', string="Instruktur")
        course_id = fields.Many2one('training.kursus', ondelete='cascade', string="Kursus", required=True)

Answer 1

In your code you have the menuitem:

<menuitem id="sesi_menu" name="Sesi" parent="training_odoo_menu" action="sesi_list_action"/>

This has the attribute parent="training_odoo_menu", however, I cannot see the parent menu item in the view?

If you want this menuitem to be the menu root, you would want to remove the parent attribute. If this exists in another module make sure that file is processed first in the manifest.

If you need anything clarifying let me know,

Thanks,
