RegistrationError at /adm about django-moderation

[dominno]

Could you tell me more information how this bug occurred ? Could you paste a trace bug ?

On first starting the server (with "manage.py runserver"), I get:

One other thing, I tried commenting out all the other external apps (reversion, etc) from my settings.py and I get the same errors.

[hexabits]

I cannot reproduce this error. You will need to show your models and model admins, along with the register lines in question.

Here's the model + register line:

[dominno]

Could you show how your microgeo\urls.py look like ? Error you are receiving probably occurs because of circular imports. Have you tried to move moderation.register(Producto) somewhere else ? ex. create file moderation.py in side of your app and add it there ?

[rodrigo-c]

That did the trick (moving moderation.register(Producto)).
Thanks!
