Hi,
i have a button in a form header. i want to display a warning when the buttons function is completed. i tried:
return {'warning': {'title': 'Warning', 'message': 'Message.'}}
but nothing happens.
also when i try to return a ir.actions.window to display a wizard nothing happens.
Hi Mitsch,
You cannot use the 'warning' in button, it can be used in onchange function.
If you want to show a warning or error inside the button function you can use 'UserError', but it will discard all changes made in that function. If the user tries to do something that has no sense in that record, you can use this. Syntax is
if 'condtion':
raise UserError('Message.')
Make sure you import UserError
from odoo.exceptions import UserError
Hope this helps.
in the view:
<record id="some_form" model="ir.ui.view">
...
<field name="arch" type="xml">
<form string="Some Name">
<header>
<button name="wkf_grant_order" type="object" string="Grant Order" states="confirmed"/>
</header>
...
</form>
</field>
</record>
in the function:
def wkf_grant_order(self):
return {'warning': {'title': 'Warning', 'message': 'Skipping granting because order is under 1000.'}}
i left out the other parts but what i tried is basically this.
an exception would actually work for the warning. but i also need to open a wizard.
you can add exception with raise
from odoo import exceptions
raise exceptions.Warning('Warning message')
raise exceptions.ValidationError('Not valid message') Créez un compte dès aujourd'hui pour profiter de fonctionnalités exclusives et échanger avec notre formidable communauté !
