Hi,
UID usage in attrs is unsupported. Instead, employ a computed field for dynamic user ID comparison
current_user_id = fields.Many2one('res.users', compute='_compute_current_ user_id', store=True)      def _compute_current_user_id(self) :     for record in self:
record.current_user_id = self.env.user
<field name="intervenant_id" attrs="{'invisible': [('intervenant_id', '!=', current_user_id)]}"/>   Utilize this computed field in the XML view's attrs attribute to make the button invisible based

Hi,

I've successfully implemented this issue by using the following code format:

attrs="{'invisible' : "[('intervenant_user_id', '=', uid)]"}"
You need to add " on both sides of the domain.

unfortunately, you can't do that comparison with uid in attrs
you can do the workaround by using the help of a new field that will always provide the current user id, like using compute or tampering with the form view nodes
