Filter kueri Django menggunakan array besar id di Postgres DB

Saya menemukan solusi yang dibangun berdasarkan jawaban @erwin-brandstetter menggunakan pencarian khusus

from django.db.models import Lookup
from django.db.models.fields import Field

@Field.register_lookup
class EfficientInLookup(Lookup):

    lookup_name = "ineff"

    def as_sql(self, compiler, connection):
        lhs, lhs_params = self.process_lhs(compiler, connection)
        rhs, rhs_params = self.process_rhs(compiler, connection)
        params = lhs_params + rhs_params
        return "%s IN (SELECT unnest(%s))" % (lhs, rhs), params

Ini memungkinkan untuk memfilter seperti ini:

MyModel.objects.filter(id__ineff=<list-of-values>)
