Hi,
Try to make like this

@api.multi def _target_achieve(self):     if self._origin:         if self._origin.id:             print("==============I RUN")         else:             raise exceptions.ValidationError('No ID')
Thanks

If you use " _target_achieve" function in compute like:

... compute=" _target_achieve"...

You won't be able to use "self._origin".
This is what I figured out after trying everything.
