Hi Ian,
Here's her's the quick model I wrote to try to select *something*:
class TestCategory(models.Model):
name = models.CharField(max_length=255)
class Meta:
db_table = 'ACTIVITY_CODE.CATEGORIES'
If I connect via dbshell from my project, I can do: select * from
categories;
and I get 11 records back, which is correct. But, if I try to retrieve
these via:
from my_app.models import TestCategory
from django.shortcuts import render_to_response
def test(request):
categories = TestCategory.objects.all()
return render_to_response('test.html', {'categories' ;
categories})
I get: DatabaseError: ORA-00942: table or view does not exist
? ? ?
