Hi,

I am trying to set an automated action to update a specific field using Studio with the following python expression :

if record.x_studio_parent_category:
  record.x_studio_parent_category.name + ' / ' + record.name

Error:
Odoo Server Error

Exception

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/home/odoo/src/odoo/14.0/odoo/http.py", line 640, in _handle_exception
    return super(JsonRequest, self)._handle_exception(exception)

    raise exception.with_traceback(None) from new_cause
  File "", line 1
    if record.x_studio_parent_category:
    ^
SyntaxError: invalid syntax

What am I doing wrong ?

Many thanks.
