Alright, this is what I *am* able to do...
manage.py shell (from my project folder)
from my_project.models import *
categories = Categories.objects.all()
print categories (and I get 11 Category objects - woohoo!)
from django.db import connection
print connection.queries
[{'time': '0.007', 'sql': u'SELECT * FROM (SELECT ROWNUM AS "_RN",
"_SUB".* FROM (SELECT "CATEGORIES"."ID", "CATEGORIES"."NAME",
"CATEGORIES"."CREATED_AT", "CATEGORIES"."UPDATED_AT" FROM
"CATEGORIES") "_SUB" WHERE ROWNUM <= 21) WHERE "_RN" > 0'}, {'time':
'0.004', 'sql': u'SELECT "CATEGORIES"."ID", "CATEGORIES"."NAME",
"CATEGORIES"."CREATED_AT", "CATEGORIES"."UPDATED_AT" FROM
"CATEGORIES"'}]
however attempting to retrieve the Category objects from a view
results in:
DatabaseError: ORA-00942: table or view does not exist
Thoughts?
