thanks for your answer. That's what I'm doing now. Unfortunately, I don't have time to dive deeper into CustomManipulators but maybe for the next project.
Best regards

Hi,
I also found that behavior and what I did was to copy
new_data['station'] to new_data['station_id'] when there were errors
from "get_validation_errors()". Like this:
def change_recording(request, recording_id):
....snip.....
if request.POST:
new_data = request.POST.copy()
errors = manipulator.get_validation_errors(new_data)
if not errors:
manipulator.do_html2python(new_data)
new_recording = manipulator.save(new_data)
return HttpResponseRedirect("/dwasrod/")
else:
new_data['station_id'] = new_data['station']
new_data['other_foreign_id'] = new_data['other_foreign']
else:
new_data = recording.__dict__
....snip....
I later had to create a custom manipulator instead of using the
default one. With a custom manipulator you don't have this field name
discrepancy, and don't need to do that value copying. I now prefer to
use a custom manipulator.
Cheers,
Jorge
