Are you tired of staring at the same old boring calendar view in Odoo? Do you long for a more visually appealing way to display your appointments and events? Look no further, my friend! In this tutorial, we're going to shake things up and create a custom calendar view that will make your colleagues and clients say “wow”. So put on your coding hat and let's dive into the world of custom views in Odoo!
Custom Module
First, we need to create a new model that will store our calendar events or appointments. We'll call this model “calendar.event” and create it in a new module named “custom_calendar”.
Here's the code for our “custom_calendar” module:
# custom_calendar/__init__.pyfrom . import modelsCode language: Python (python)# custom_calendar/models/__init__.pyfrom . import calendar_eventCode language: Python (python)# custom_calendar/models/calendar_event.pyfrom odoo import fields, modelsclass CalendarEvent(models.Model): _name = 'calendar.event' _description = 'Calendar Event' name = fields.Char(string='Event Name', required=True) start_date = fields.Datetime(string='Start Date', required=True) end_date = fields.Datetime(string='End Date', required=True) description = fields.Text(string='Description')Code language: Python (python)This code defines a new model “calendar.event” with four fields: name, start_date, end_date, and description. The “name” field will store the name of the event, “start_date” and “end_date” will store the start and end times of the event, and “description” will store any additional information about the event.
Let's Add more fields
Next, we'll add a few more fields to our “calendar.event” model to help with the calendar view. We'll add a “color” field to specify the color of the event in the calendar, and a “recurrence” field to specify whether the event is recurring.Here's the updated code for our “calendar.event” model:
# custom_calendar/models/calendar_event.pyfrom odoo import fields, modelsclass CalendarEvent(models.Model): _name = 'calendar.event' _description = 'Calendar Event' name = fields.Char(string='Event Name', required=True) start_date = fields.Datetime(string='Start Date', required=True) end_date = fields.Datetime(string='End Date', required=True) description = fields.Text(string='Description') color = fields.Integer(string='Color Index') recurrence = fields.Selection( [('none', 'None'), ('daily', 'Daily'), ('weekly', 'Weekly'), ('monthly', 'Monthly'), ('yearly', 'Yearly')], string='Recurrence', default='none')Code language: Python (python)We've added a new “color” field of type Integer, which will store the index of the color for the event in the calendar. We've also added a new “recurrence” field of type Selection, which will allow users to select whether the event is recurring, and if so, how often it recurs.
Now that we've defined our “calendar.event” model and its fields, we need to add some data to test our custom calendar view. Let's create a new record for our model with some sample data.
Go to the “Settings” menu in Odoo and click on “Technical” > “Database Structure” > “Models”. Find the “calendar.event” model and click on it. Then click the “Create” button to create a new record. Fill in the fields with some sample data, such as the name “Test Event”, start and end dates, and a description. Save the record and close the form.We now have a sample event to display in our custom calendar view.
Views
Next, we need to create a new view that will display our custom calendar. In Odoo, views are defined in XML files. Let's create a new XML file called “calendar_views.xml” in our “my_module/views” directory and add the following code:
<?xml version="1.0" encoding="UTF-8"?><odoo> <data> <!-- Define the calendar view for our model --> <record id="view_calendar_appointment_tree" model="ir.ui.view"> <field name="name">Appointment Calendar</field> <field name="model">my_module.appointment</field> <field name="arch" type="xml"> <calendar string="Appointment Calendar" date_start="start_datetime" date_stop="stop_datetime" mode="month"> <field name="name"/> <field name="start_datetime"/> <field name="stop_datetime"/> <field name="color"/> <field name="user_id"/> <field name="state"/> <field name="partner_id"/> <field name="display_name"/> <field name="duration"/> </calendar> </field> </record> </data></odoo>Code language: HTML, XML (xml)This code defines a new view called “Appointment Calendar” for our “my_module.appointment” model. It uses the <calendar> tag to define the structure of our custom calendar view. We've included several fields from our model, such as “name”, “start_datetime”, “stop_datetime”, “color”, etc. You can customize this view by adding or removing fields as per your requirement.
Manifest
Now, let's include this new view in our module by adding the following code to our “my_module/manifest.py” file:
# ...'data': [ 'views/appointment_views.xml', 'views/calendar_views.xml',],# ...Code language: Python (python)This code tells Odoo to load our new “calendar_views.xml” file along with our “appointment_views.xml” file when our module is installed.
Finally, let's restart Odoo and navigate to our “Appointments” menu. From there, click on the “Calendar” button to view our new custom calendar. You should now see a fully functional calendar view displaying all appointments in our system.
Things to consider
Here are some tips related to the custom module we built for creating a custom calendar view in Odoo:
- Use clear and concise model names: When creating models for your custom module, choose names that accurately reflect their purpose. This will make it easier for other developers to understand your code and work with your module.
- Pay attention to naming conventions: In Odoo, there are specific naming conventions for fields, methods, and other elements of a module. Make sure you follow these conventions to ensure consistency and avoid potential errors.
- Use comments and documentation: When writing code, make sure to include comments and documentation that explain what your code does and how it works. This will make it easier for other developers to understand and work with your module.
- Test your module thoroughly: Before releasing your module, make sure to test it thoroughly to ensure that it works as expected and doesn't cause any conflicts with other modules.
- Keep your code modular: Try to break your code down into small, reusable modules that can be easily modified and maintained. This will make it easier to update your module in the future and avoid potential issues down the line.
Congratulations! You've just created a custom calendar view for displaying events or appointments in Odoo.
