Hello,

In Odoo 18, I use the readonly attribute:

<field name="name" readonly="boolean condition"/>

Where boolean condition is a boolean, like status == 'validated'.

I would like to refer to the current day (today) in a readonly, something like this:

<field name="name" readonly=revision_date &lt;= Date.today()"/>

With a "revision_date" in my model.


Thank you in advance,

Boris

P.S. It's working with a cron running everyday but it is probably possible to have something simpler.

Thank you very much.

Before reading your posts, I use the method 1.

You would usually create a computed field to check against to achieve this.

For example:

is_record_readonly = fields.Boolean(compute='_compute_is_record_readonly')

@api.depends('revision_date')
def _compute_is_record_readonly(self):
    for record_id in self:
        record_id.is_record_readonly = True if record_id.revision_date <= fields.Date.today() else False

and use it as

<field name="name" readonly="is_record_readonly"/>

Hi,


Try with the following code 

<field name="name" readonly="revision_date &lt; context_today()"/>

Hope it helps

You want a field (like name) to become read-only after a certain date (revision_date). Here’s the simplest way to do it:

Method 1: Best & Easy Way (Recommended)

1. Add a computed field to your model:

python

from odoo import models, fields, api
from datetime import date

class YourModel(models.Model):
    _name = 'your.model'

    revision_date = fields.Date(string='Revision Date')
    name = fields.Char(string='Name')
    is_name_readonly = fields.Boolean(compute='_compute_is_name_readonly')

    @api.depends('revision_date')
    def _compute_is_name_readonly(self):
        today = date.today()
        for record in self:
            # If revision_date is past or today, make 'name' read-only
            record.is_name_readonly = record.revision_date and record.revision_date <= today

2. Update your XML view:

xml

<field name="name" readonly="is_name_readonly"/>
<field name="is_name_readonly" invisible="1"/>  <!-- Hide helper field -->

Why this works:

  • The is_name_readonly field automatically updates when revision_date changes.
  • No complex code or cron jobs needed.
Method 2: Quick Fix (For Simple Cases)

If you prefer no code changes, use attrs in XML:

xml

<field name="name" attrs="{'readonly': [('revision_date', '&lt;=', context_today())]}"/>

⚠️ Limitation: Slower for large datasets.

Key Notes
  • Method 1 is faster and works for all records.
  • Method 2 is simpler but less efficient.
  • Never use Date.today() directly in XML—it won’t work!

Need the field to update daily?

Add a scheduled action (cron) to recompute is_name_readonly nightly.

Try Method 1 first! It’s cleaner and more reliable. 🚀
