Hi,
I have created two models as this:
|
classCampaign(models.Model):
name =models.CharField(max_length=255)
classCampaignExt(Campaign):
status =models.IntegerField()
|
In my APIView I do this:
|
defget(self,request,campaign_id,response_format=None):
campaigns =CampaignExt.objects.raw("""\
SELECT
c.id,
c.name,
c.status
FROM campaign c
WHERE c.id = %(id)s
"""%{"id":campaign_id });
|
The traceback looks like this:

ExceptionValue:Rawquery must include the primary key

As I have the primary key in the query I reckon that this should work.
But it seems that the CampaignExt model does not know about the primary
key as if it has not inherited this from the Campaign model.
When I just create two models with a separated list of fields like this:
|
|classCampaign(models.Model):
name =models.CharField(max_length=255)
classCampaignExt(||||models.Model||):
||||name =models.CharField(max_length=255)
|| status =models.IntegerField()
|
|
It works as expected. Can you help me what I am missing? Here is my
environment:
Django 1.7.1
Python 3.4.2
Rest_Framework 2.4.3
Thanks,
Tobias.
