Here's how you can use the '@api.depends' decorator effectively in Odoo computed fields. This example shows a basic implementation and explains how it works. The '@api.depends' decorator is crucial for computed fields. It specifies the fields that a computed method depends on, ensuring that the method is triggered to recalculate when any of these dependent fields are changed. class CustomModel(models.Model): _name = 'custom.model' my_field = fields.Integer(compute='_compute_my_field') @api.depends('other_field') def _compute_my_field(self): for record in self: record.my_field = record.other_field * 2
