MultiWidget does not detect changed values on an Inline - newforms-admin

Initial values saved via a MultiWidget in an Inline form in the admine, are saved properly. Subsequent changes to an existing record are not saved. I discovered this with my own MultiWidget, but tested it with a SplitDateTimeField as well.

To reproduce, place a DateTimeField into any Inline model. Save a new record. Works. Change that record. Doesn't work.

I've narrowed this down to a problem in the MultiWidget._has_changed method. Poor test coverage didn't catch this error. Will have this fixed shortly.

  • Resolution set to fixed
  • Status changed from assigned to closed

(In [7517]) newforms-admin: Fixed #7160 -- MultiWidget._has_changed was short-circuiting while testing for changed data in its widgets. Added tests to ensure this won't get broken in the future.
