Hi guys, I cannot configure Calendar to show duration of the event in Calendar view

I use Odoo 18.


p.s. I want to inset examples, but Odoo edit form doesn't allow me to do so...

This is what I have: https://shottr.cc/s/1fd6/SCR-20250717-f5x





class MyEvent(models.Model):
    _name = 'mymodule.my_event'
    _description = 'My Event'

    name = fields.Char("Title", required=True)

    date_start = fields.Datetime("Start", required=True)
    date_stop = fields.Datetime("End", required=True)

    priority = fields.Selection([
        ('low', 'Low'),
        ('normal', 'Normal'),
        ('high', 'High')
    ], string="Priority")


This is my XML for calendar view:


<odoo>
    <record id="view_mymodule_my_event_calendar" model="ir.ui.view">
        <field name="name">view_mymodule_my_event_calendar</field>
        <field name="model">mymodule.my_event</field>
        <field name="arch" type="xml">
            <calendar
                    string="My Calendar"
                    date_start="date_start"
                    date_stop="date_stop"
                    color="priority"
                    mode="week"
                    event_open_popup="true">
                <field name="name"/>
                <field name="priority"/>
            </calendar>
        </field>
    </record>
</odoo>


Please Help!

Hii,

Here is updated code please try this 

Python Model (models/my_event.py)
from odoo import models, fields

class MyEvent(models.Model):
    _name = 'mymodule.my_event'
    _description = 'My Event'

    name = fields.Char("Title", required=True)
    date_start = fields.Datetime("Start", required=True)
    date_stop = fields.Datetime("End", required=True)

    priority = fields.Selection([
        ('low', 'Low'),
        ('normal', 'Normal'),
        ('high', 'High')
    ], string="Priority", default='normal')
XML View File (views/my_event_views.xml)
<odoo>

    <!-- Calendar View -->
    <record id="view_my_event_calendar" model="ir.ui.view">
        <field name="name">my_event.calendar</field>
        <field name="model">mymodule.my_event</field>
        <field name="arch" type="xml">
            <calendar
                string="My Events"
                date_start="date_start"
                date_stop="date_stop"
                color="priority"
                event_open_popup="true"
            >
                <field name="name"/>
            </calendar>
        </field>
    </record>

    <!-- Tree View -->
    <record id="view_my_event_tree" model="ir.ui.view">
        <field name="name">my_event.tree</field>
        <field name="model">mymodule.my_event</field>
        <field name="arch" type="xml">
            <tree>
                <field name="name"/>
                <field name="date_start"/>
                <field name="date_stop"/>
                <field name="priority"/>
            </tree>
        </field>
    </record>

    <!-- Form View -->
    <record id="view_my_event_form" model="ir.ui.view">
        <field name="name">my_event.form</field>
        <field name="model">mymodule.my_event</field>
        <field name="arch" type="xml">
            <form>
                <sheet>
                    <group>
                        <field name="name"/>
                        <field name="date_start"/>
                        <field name="date_stop"/>
                        <field name="priority"/>
                    </group>
                </sheet>
            </form>
        </field>
    </record>

    <!-- Action -->
    <record id="action_my_event" model="ir.actions.act_window">
        <field name="name">My Events</field>
        <field name="res_model">mymodule.my_event</field>
        <field name="view_mode">calendar,tree,form</field>
        <field name="view_id" ref="view_my_event_calendar"/>
        <field name="help" type="html">
            <p class="o_view_nocontent_smiling_face">
                Create your first event
            </p>
        </field>
    </record>

    <!-- Menu -->
    <menuitem id="menu_my_event_root" name="My Module"/>

    <menuitem id="menu_my_event_main" name="My Events"
              parent="menu_my_event_root"
              action="action_my_event"/>

</ odoo >
Manifest (__manifest__.py)

Ensure you include the XML file in data:

{
    'name': 'My Custom Calendar Module',
    'version': '1.0',
    'depends': ['base'],
    'data': [
        'views/my_event_views.xml',
    ],
    'application': True,
}

I hope it is of full use.

Thank you for your reply, but is has the same problem:

**in a Day or Week View I do not not see event duration**

Please see these links to understand the problem:

Here is what I have on a week view: https://shottr.cc/s/1QyA/SCR-20250717-f4n
Here is what I want/expect to see: https://shottr.cc/s/1fd6/SCR-20250717-f5x

Hii
Update the Python Model
python
Copy
Edit
from odoo import models, fields, api
from datetime import timedelta

class MyEvent(models.Model):
_name = 'mymodule.my_event'
_description = 'My Event'

name = fields.Char("Title", required=True)
date_start = fields.Datetime("Start", required=True)
date_stop = fields.Datetime("End", required=True)
priority = fields.Selection([
('low', 'Low'),
('normal', 'Normal'),
('high', 'High')
], string="Priority", default='normal')

duration = fields.Float("Duration", compute="_compute_duration", store=True)

@api.depends('date_start', 'date_stop')
def _compute_duration(self):
for rec in self:
if rec.date_start and rec.date_stop:
delta = rec.date_stop - rec.date_start
rec.duration = delta.total_seconds() / 3600.0 # in hours
else:
rec.duration = 0
Update Calendar View to Use duration
Update your calendar tag in my_event_views.xml to include:

xml
Copy
Edit
<calendar
string="My Events"
date_start="date_start"
date_stop="date_stop"
duration="duration"
color="priority"
event_open_popup="true"
>
<field name="name"/>
</calendar>
please try this and upgrade your module
i hope it is usefull
