Re: Relation fields do not support nested lookups

A minimal project that reproduces the error would be helpful. Please avoid duplicating your post on django-users and in Trac (until it's a confirmed bug in Django). Thanks!

He all,

Does anyone know why i can't do any relation lookups on any database other then the default database in 1.8.5 this worked fine in 1.6.1

it keeps trowing me: Relation fields do not support nested lookups

for example on

adds = ProfielenFlirts.objects.filter(voor__user__profielenuserprofile__fictief=True).filter(Q(antwoord='') | Q(antwoord__isnull=True)).count()

ProfielenFlirts is a non default database, the relation lookup is in the same database do.

my router

class DatingRouter(object):
    def db_for_read(self, model, **hints):
        if model._meta.app_label == 'datingmodels':
            return 'dating'
        return 'default'

    def db_for_write(self, model, **hints):
        if model._meta.app_label == 'datingmodels':
            return 'dating'
        return 'default'

    def allow_relation(self, obj1, obj2, **hints):
        if obj1._meta.app_label == 'datingmodels' and obj2._meta.app_label == 'datingmodels':
            return True
        elif 'datingmodels' not in [obj1._meta.app_label, obj2._meta.app_label]:
            return True
        return False

    def allow_syncdb(self, db, model):
        if db == 'dating' or model._meta.app_label == "datingmodels":
            return False # we're not using syncdb on our legacy database
        else: # but all other models/databases are fine
            return True

any help would be appriciated
