To implement Internal Team Grouping for Calendar Invitations in Odoo (v16, v17, or v18), you'll need to customize the calendar and contact functionalities. The idea is to create a custom model for "Internal Teams" and allow selection of this team when creating meetings so invites go to all team members.

Step-by-Step Implementation

1.Create a Custom Model: internal.team

Add a model to define internal teams and assign users.

# models/internal_team.py
from odoo import models, fields

class InternalTeam(models.Model):
    _name = 'internal.team'
    _description = 'Internal Team'

    name = fields.Char(string='Team Name', required=True)
    member_ids = fields.Many2many('res.users', string='Team Members')

2.Extend Calendar Event to Link a Team

Add a Many2one field to select an internal team in calendar events.

# models/calendar_event.py
from odoo import models, fields, api

class CalendarEvent(models.Model):
    _inherit = 'calendar.event'

    team_id = fields.Many2one('internal.team', string='Internal Team')

    @api.onchange('team_id')
    def _onchange_team_id(self):
        if self.team_id:
            self.partner_ids = [(6, 0, self.team_id.member_ids.mapped('partner_id').ids)]

3. Update Views

has. Add a menu for Internal Team:

<!-- views/internal_team_view.xml -->
<odoo>
  <record id="view_internal_team_form" model="ir.ui.view">
    <field name="name">internal.team.form</field>
    <field name="model">internal.team</field>
    <field name="arch" type="xml">
      <form string="Internal Team">
        <sheet>
          <group>
            <field name="name"/>
            <field name="member_ids"/>
          </group>
        </sheet>
      </form>
    </field>
  </record>

  <record id="view_internal_team_tree" model="ir.ui.view">
    <field name="name">internal.team.tree</field>
    <field name="model">internal.team</field>
    <field name="arch" type="xml">
      <tree>
        <field name="name"/>
        <field name="member_ids"/>
      </tree>
    </field>
  </record>

  <menuitem id="menu_internal_team_root" name="Internal Teams" parent="base.menu_custom" sequence="10"/>
  <menuitem id="menu_internal_team" name="Manage Teams" parent="menu_internal_team_root" action="action_internal_team"/>
</odoo>

b. Extend calendar event view to add team_id :

<!-- views/calendar_event_inherit.xml -->
<odoo>
  <record id="view_calendar_event_form_inherit_team" model="ir.ui.view">
    <field name="name">calendar.event.form.inherit.team</field>
    <field name="model">calendar.event</field>
    <field name="inherit_id" ref="calendar.view_calendar_event_form"/>
    <field name="arch" type="xml">
      <xpath expr="//field[@name='partner_ids']" position="before">
        <field name="team_id"/>
      </xpath>
    </field>
  </record>
</odoo>

4.Security and Access Control

Ensure access to internal.team model for internal users.

<!-- security/ir.model.access.csv -->
access_internal_team_user,access.internal.team.user,model_internal_team,base.group_user,1,1,1,1

5. Final Result

• User selects a team in the calendar form.
• All members of that team are automatically added as attendees ( partner_ids ) to the event.
• They receive invitations as usual.
