Renamed a field in the queries test schema that was preventing the tests from...

# A model and custom default manager combination.

class CustomManager(models.Manager):

    def get_query_set(self):

        return super(CustomManager, self).get_query_set().filter(public=True,

                tag__name='t1')

        qs = super(CustomManager, self).get_query_set()

        return qs.filter(is_public=True, tag__name='t1')

class ManagedModel(models.Model):

    data = models.CharField(max_length=10)

    tag = models.ForeignKey(Tag)

    public = models.BooleanField(default=True)

    is_public = models.BooleanField(default=True)

    objects = CustomManager()

    normal_manager = models.Manager()

Bug #7095

Updates that are filtered on the model being updated are somewhat tricky to get

in MySQL. This exercises that case.

>>> mm = ManagedModel.objects.create(data='mm1', tag=t1, public=True)

>>> mm = ManagedModel.objects.create(data='mm1', tag=t1, is_public=True)

>>> ManagedModel.objects.update(data='mm')
