Re: "Raw query must include the primary key" when inheriting models

Hi Tobias,

Based on your database query, it looks like you are not doing multiple table inheritance, but your models are set up for multiple table inheritance.

https://docs.djangoproject.com/en/dev/topics/db/models/#model-inheritance

Why not just have a status field on your Campaign model? Django expects each (non abstract, non proxy) model to map to a database table.

If you are doing multiple table inheritance, I'm guessing the primary key that django is expecting would be the auto generated campaign_ptr_id, which would live on the campaignext table.

In you are doing multiple table inheritance, why not just do CampaignExt.objects.get(id=campaign_id) ?
