Django inline objects not getting saved

Can anyone who tell us where is the code for django to save the inline form objects in admin site?

I've got an issue that the django does not pick up the field I typed in in an inline form. I th开发者_StackOverflowink I should overwrite the save method somewhere..

Inline formsets are saved here: http://code.djangoproject.com/browser/django/trunk/django/contrib/admin/options.py#L678

Called from both add_view and change_view in the same file.
