Re: TEST_MIRROR not working?

I ended up opening a ticket https://code.djangoproject.com/ticket/23718 after fining my testcase actually works against Django 1.3.7

Both settings have same effect.

I've slightly modified testcase to demonstrate replica queries are not the same as master queries (no fixtures):

    def test_fixture(self):

        MyModel.objects.using('default').create(name=1)

        MyModel.objects.using('slave').create(name=2)

        MyModel.objects.using('slave').create(name=3)

        self.assertEqual(MyModel.objects.using('default').count(),

                         MyModel.objects.using('slave').count())

======================================================================

FAIL: test_fixture (testapp.tests.TestMirror)

----------------------------------------------------------------------

Traceback (most recent call last):

  File "/Users/prophet/work/forks/test_mirror/testmirror/testapp/tests.py", line 13, in test_fixture

    MyModel.objects.using('slave').count())

AssertionError: 3 != 2

Actually, in 1.7.x both should work.

This should be 'TEST_MIRROR': 'default'
