How to use onchange method in odoo

The change method in Odoo is used to trigger actions when a field value changes in the user interface. It allows developers to automatically update other fields based on the value entered in a specific field. To use on change, define it as a decorator method in your model, passing the fields to be monitored as parameters. When the specified field is modified, the process is executed, and the corresponding actions are performed, such as recalculating values or updating other fields dynamically. This enhances user experience and streamlines workflows.
