from openerp.tools.translate import _
raise osv.except_osv(_('Invalid Action!'), _('You can not create this payment. reconfirm the form once again.'))
Isio,
Exception is the way to go, but for an another idea , please check if the popup reminder helps you on this.
Here is the module : https://www.odoo.com/apps/modules/8.0/popup_reminder
Thanks.
Could you explain the use case in more detail?
If you want to pop up the alert on click of a button, you could use:
<button string="my_button" confirm="Are you sure?" />
This will be in the XML file
If you want to raise it as an alert on programming logic, you could use:
raise osv.except_osv(('Permission Denied!'),('You are not allowed to perform this operation.'))
This will be in .py file
If you want it on click of some javascript event, then:
alert("Error !");
This would be in your .js file.
Please describe the scenario you want to show this error.
