#32006: QuerySet with values with annotate generates wrong SQL query -------------------------------------+------------------------------------- Reporter: | Owner: nobody Konstantin Popov | Type: Bug | Status: new Component: Database | Version: 3.1 layer (models, ORM) | Keywords: QuerySet values Severity: Normal | annotate GROUP BY Triage Stage: | Has patch: 0 Unreviewed | Needs documentation: 0 | Needs tests: 0 Patch needs improvement: 0 | Easy pickings: 0 UI/UX: 0 | -------------------------------------+------------------------------------- I use values and annotate on QuerySet to make query for my report. When I add 'id' or 'pk' field to another fields in values it becomes the only field in GROUP BY clause. This, obviously, generates an invalid SQL query.
{{{ str(Currency.objects.filter(status=3).values('sifr','guid').annotate(cnt=Count('*')).query) }}} 'SELECT "rk7data_currency"."sifr", "rk7data_currency"."guid", COUNT(*) AS "cnt" FROM "rk7data_currency" WHERE "rk7data_currency"."status" = 3 GROUP BY "rk7data_currency"."sifr", "rk7data_currency"."guid"' {{{ str(Currency.objects.filter(status=3).values('sifr','guid','id').annotate(cnt=Count('*')).query) }}} 'SELECT "rk7data_currency"."sifr", "rk7data_currency"."guid", "rk7data_currency"."id", COUNT(*) AS "cnt" FROM "rk7data_currency" WHERE "rk7data_currency"."status" = 3 GROUP BY "rk7data_currency"."id"' I have checked this on several models with the same result. I have discovered this on django 2.2.10. Upgrade to 2.2.16 and even to 3.1 does not solve the problem. -- Ticket URL: <https://code.djangoproject.com/ticket/32006> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
