Hi Fabien,

In Odoo, the act_window action provides several targets such as current, new, inline, fullscreen, and main. You can try each of these targets, and if none of them meet your requirements for redirecting to a new tab, you can use the following approach:

python

base_url = self.env['ir.config_parameter'].get_param('web.base.url')
record_url = base_url + '/web#id=' + str(self.id) + '&view_type=form&model=WWW&menu_id=XXX&action=YYY'

client_action = {
    'type': 'ir.actions.act_url',
    'name': 'ZZZ',
    'target': 'new',
    'url': record_url,
}

This code constructs a URL for the record based on its ID and other parameters, and then creates a client action of type ir.actions.act_url with a target set to new to open the URL in a new tab.

Hope it helps

Thank you for your reply. 

I attempted to modify the target attribute to "new," but this action still opens the results in the same window within a new pop-up. 

However, my intention is to have the results open in a new tab.

Hi

Hope everything is good 

you can try like below

def test_button(self):
	​return {
     	​'type': 'ir.actions.act_window',
     	​'res_model': 'ir.attachment',
     	​'view_mode': 'kanban',
    	​ 'target': 'new',
    	​ 'domain': [('res_model', '=', self._name), ('res_id', '=',  self.id)],
	​}
