Comment (by ris):
Updating this with example models.py for creating this failure:
{{{
from django.db import models
from django.db.models import Transform
class Sqrt ( Transform ):
lookup_name = "sqrt"
def as_sql ( self , qn , connection ):
lhs , params = qn.compile ( self.lhs )
return "sqrt(%s)" % lhs , params
models.FloatField.register_lookup ( Sqrt )
class ModelA ( models.Model ):
x = models.FloatField ()
class ModelB ( models.Model ):
a = models.ForeignKey ( ModelA )
}}}
Issuing the query:
{{{
ModelB.objects.filter ( a__pk__in = ModelA.objects.filter ( x__sqrt__lt =
5 ) )
}}}
raises the above exception.
I've used this test case to verify that this bug is still present in
django 1.8.2.
