django.db.utils.DatabaseError: ORA-00918: column ambiguously defined
The particular line of code that triggers it is:
store_obj =
Store.objects.select_related('address','brand','store_status','pos_app','timezone','business_line','store_type').\
get(id=pk)
I understand that the error is an indication of the same column names in
different tables, but for me the ORM is obscuring how to fix this problem
in this case.
Any ideas? I'd appreciate any way to debug this that you have a suggestion.
Thanks.
