With the "ir.actions.act_url" you can open the view in a new tab by forming a URL of the view.

url = self.env['ir.config_parameter'].sudo().get_param('web.base.url')
url += '/web#id=%s&&model=sale.order&view_type=form' % self.id
return {
            'type': 'ir.actions.act_url',
            'target': 'new',
            'url': url,
        }

Not working means nothing happens when you click on a button or you are getting an error.

The simplest way i can think of is to add a button in list view. 
when you click on this button you render a form view ( or a popup ) displaying all data you need.

your button's action must return smth like this: 

return {
     "name": _("your text"),
     "type": 'ir.actions.act_window',
     'view_mode': 'form'     "res_model": 'your model',
     'view_id': ref to your form view id,
     "views": [[False, "form"]],
     "target": 'new',
     "context": {
        context if necessary
    },
}
