How do you show the created value in the admin panel with django-model-utils ?

Answer 1

Based on the error, it looks like created and modified are not attributes on your model (meetings.Company).

Are you sure you have added these fields to your Company model.

If this doesn't solve your problem, can you add your model to the question.
