How to avoid brackets in SQL around Django custom database function call?
I've managed to get (more or less) what you need using following:
from django.db.models.lookups import BuiltinLookupfrom django.db.models.fields import Fieldclass Any(BuiltinLookup): lookup_name = 'any' def get_rhs_op(self, connection, rhs): return " = ANY(%s)" % (rhs,)Field.register_lookup(Any)and query:
Vehicle.objects.filter(make__any=F('dealer__make_list')).count()as result:
SELECT COUNT(*) AS "__count" FROM "zz_vehicle" INNER JOIN "zz_dealer" ON ("zz_vehicle"."dealer_id" = "zz_dealer"."id") WHERE "zz_vehicle"."make" = ANY(("zz_dealer"."make_list"))btw. instead djorm_pgarray and TextArrayField you can use native django:
make_list = ArrayField(models.CharField(max_length=200), blank=True)(to simplify your dependencies)
