Invalid query for OneToOneField if 'to_field' specified and primary_key=True — at Version 1

Description (last modified by Vitaliy Yelnik)

Given the following models:

class Model1(models.Model):
    str_id = models.CharField(max_length=12, unique=True)


class Model2(models.Model):
    model1 = models.OneToOneField(Model1, to_field='str_id', primary_key=True)

In Django 1.9 query:

Model2.objects.filter(model1=instance_model1)

always returns an empty list, though in Django 1.8 works

Django 1.9 query

In [4]: print Model2.objects.filter(model1=instance_model1).query
SELECT "app_model2"."model1_id" FROM "app_model2" WHERE "app_model2"."model1_id" = 1

Django 1.8 query

In [4]: print Model2.objects.filter(model1=instance_model1).query
SELECT `app_model2`.`model1_id` FROM `app_model2` WHERE `app_model2`.`model1_id` = 1234567890ax
