Warning message not working on openerp

Question

I want to show a warning message in user interface side in my module in a particular condition.For that I have write the code like this.

raise osv.except_osv(('Warning!'), ("Entered Quantity is greater than quantity on source."))

But in that condition in user interface side it just showing the loading image.

At the console I got the error like this.

I want to show the warning message on user interface side.

Answer 1

First you need to import

from openerp.tools.translate import _

then, you can get the job done!

raise osv.except_osv(_(u'TitleMessage'), _(u'BodyMessage'))

Answer 2

If you just want to display a warning message, you might look at using the action_warn client action. You invoke it by returning a dictionary like this one from your server action:

{
    'type': 'ir.actions.client',
    'tag': 'action_warn',
    'name': 'Warning',
    'params': {
       'title': 'Warning!',
       'text': 'Entered Quantity is greater than quantity on source.',
       'sticky': True
    }
}

This may be more genteel than you're looking for, though, if you want something that will actually stop a form submission. It displays a Growl-like notification in the user's browser. But if all you want to do is give the user some feedback in the form of a notification, either this or action_info (invoked the same way as action_warn) should do nicely.

I've got a fuller example up on my blog, but hopefully this is enough to get you going in the right direction.

Answer 3

I faced the same probleme and I resolved by :

from odoo import models, fields, api, _, osv # here add osv

raise osv.osv.except_osv(('Warning!'), ("Entered Quantity is greater than quantity on source.")) # here replace osv by osv.osv

I did this b-coz you will find the finction in odoo/osv/osv.py file

Answer 4

Can you check with below code

raise osv.except_osv('Warning!', "Entered Quantity is greater than quantity on source.")

If you need translated messages then try _('meesage....')

But do not miss to import statement

from openerp.tools.translate import _
