Comment:
I suggest you have a look at the
[https://docs.djangoproject.com/en/3.1/howto/custom-lookups/#custom-
lookups custom lookups] documentation.
Something along these lines should work
{{{#!python
from django.db.models import Lookup
class GenericIPAddressFieldContainedBy(Lookup):
name = 'contained_by'
def as_postgresql(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 << %s' % (lhs, rhs), params
models.GenericIPAddressField.register_lookup(GenericIPAddressFieldContainedBy)
}}}
Please TicketClosingReasons/UseSupportChannels next time as this is likely
something you could have received support for there.
