Dear Jort,

I want to change de name of the column of the view, I don't want to change the value of the field.

Exemple :

<field name="var1" string="valuevar1_field_value" />

Kind regards

In that case I misunderstood. Your use case is a bit more complicated, but you can check out the following blog post, which might help you further:

If you want real time updates you would have to use javascript for this, i.e., when the value of 'valuevar1' changes in the view then the field string should update as well.

Thanks Jort,

I have changed a little bit the code for it's running in odoo 17

the new code is :

@api.model
def _get_view(self, view_id=None, view_type='form', **options):
arch, view = super()._get_view(view_id, view_type, **options)
if view_type == 'form':
parameters = self.env['ir.config_parameter'].sudo()
name_var1 = parameters.get_param('app1.var1')
if (name_var1 != False):
for node in arch.xpath(
"//field[@name='var1']"
):
node.attrib['string'] = name_var1
return arch, view

Kind regards
