How to Dynamically Hide Fields in Odoo v16 Based on the Parent Record Value

by

What will you learn?

In this tutorial, you will master the art of conditionally hiding fields in a child record based on the value of its parent record in Odoo v16. You will explore techniques to dynamically control field visibility using domain filters and XML view attributes.

Introduction to the Problem and Solution

In Odoo v16, customizing field visibility based on parent record values is crucial for improving user experience and data presentation. To achieve this, we can leverage computed fields and frontend modifications. By defining appropriate conditions and dependencies, we can dynamically hide or show fields as needed.

Code

from odoo import models, fields, api

class SaleOrderLine(models.Model):
    _inherit = 'sale.order.line'

    @api.depends('order_id.some_field')  
    def _compute_hide_field_condition(self):
        for line in self:
            if line.order_id.some_field == 'some_value_to_trigger_hiding':
                line.field_to_hide = False  

    field_to_hide = fields.Char(string="Field To Hide", compute="_compute_hide_field_condition", store=True)

Note: Replace ‘some_field’, ‘some_value_to_trigger_hiding’, and ‘Field To Hide’ with actual field names from your module.

Explanation

To dynamically hide fields based on parent record values: 1. Define a computed method that evaluates when to hide/show the target field. 2. Utilize attributes like invisible=”context.get(‘hide_field’)”, which can be set/unset dynamically based on conditions.

    How do I determine which field should be hidden?

    Identify the condition triggering hiding and incorporate logic within your computed method accordingly.

    Can I use this approach for multiple fields simultaneously?

    Yes, extend your computation logic to handle multiple dependent/computed fields effectively.

    Is there any performance impact due to these computations?

    Optimize computations to avoid performance issues; follow efficient coding practices.

    Should I consider security implications while implementing dynamic visibility changes?

    Always validate user access rights before programmatically hiding sensitive information.

    Can I extend this technique beyond hiding? Like making them read-only instead?

    Absolutely! Modify attributes like readonly or required based on similar conditions for enhanced customization.

    How do I debug if my conditional hiding isn’t working as expected?

    Use print statements within computed methods or leverage Odoo’s logging features for better debugging insights during computation.

    Conclusion

    Mastering dynamic field visibility management based on parent records elevates customization capabilities within Odoo applications. By combining backend computations with frontend modifications, developers can craft interactive interfaces tailored to specific business needs efficiently.
