menu item and its action didn't work in odoo13

Question

I started to learn odoo13 latterly and I am trying to add an appointment menu item to my app in the same steps I did with the patient menu item & didn't work so these are the steps that I did

1. inside the model folder that I have created I put my appointment.py file

   from odoo import fields, models, api, _ class HospitalAppointment(models.Model): _name = "hospital.appointment" _inherit = ['mail.thread', 'mail.activity.mixin'] _description = "Appointment For Patients" @api.model def create(self, vals): if vals.get('name', _('New')) == _('New'): vals['name'] = self.env['ir.sequence'].next_by_code('hospital.appointment') or _('New') result = super(HospitalAppointment, self).create(vals) return result name = fields.Char(string='Appointment ID', required=True, copy=False, readonly=True, index=True, default=lambda self: _('New')) # patient_id = fields.Integer('ID Number') patient_id = fields.Many2one('hospital.patient', string='Patient', required=True) patient_age = fields.Integer('Age') notes = fields.Text(string='Registration Notes') appointment_date = fields.Date(string='Date', required=True)```

2. code inside init .py file that is inside models folder

from . import patient
from . import appointment

3. code inside appointment.xml file that is inside view folder

<?xml version="1.0" encoding="utf-8"?>

please help me find why odoo doesn't create my menu item? I tried to restart the server many times too

Answer 1

Make sure the root menu id is the same as you declared in parent="hospital_root"

for exemple:

<menuitem id="menu_hospital_root"
          name="Hospital"/>

Child menu:

 <menuitem id="menu_appointment"
           name="Appointments"
           parent="menu_hospital_root""/>
