Django ORM: Filter by extra attribute

Question

I want to filter some database objects by a concatenated string.

The normal SQL query would be:

SELECT concat(firstName, \' \', name) FROM person WHE         


        

Answer 1

The proposed solution worked great with postgresql and JSONB fields in the code below. Only records that have the 'partner' key under the 'key' jsonb field are returned:

query_partner = "select key->>'partner' from accounting_subaccount " \
                "where accounting_subaccount.id = subaccount_id and key ? 'partner'"
qs = queryset.extra(select={'partner': query_partner}, where=["key ? 'partner'"])
