AssertionError: 400 != 201 when running APITestCase after TestCase

Here is the problem: I have 2 seperate tests, one is based on Django's TestCase and another one inherits from APITestCase (Django Rest Framework). When running separately no errors occur, but when I run APITestCase after TestCase self.assertEqual(response.status_code, status.HTTP_201_CREATED) doesn't work anymore.

Here is a part of code:

class CalendarTests(APITestCase):
    def setUp(self):
        self.user = User.objects.create_user(
            email='[email protected]', password='secret', username='tester')
        self.calendar = Calendar(owner=self.user, caltype='p', name='Test Calendar')
        self.calendar.save();

    def test_api_create_bla(self):
        self.client.login(username='[email protected]', password='secret')
        url = reverse('calendar-api')
        data_initial = {'text': 'testing hurray', 'cal_date':'2015-03-15', 'calendar':1}
        data_expected = {'cal_date': '2015-03-15',
                         'text': u'testing hurray',
                         'otype': 'd', 
                         'owner': u'tester', 
                         'calendar': 1,
                         'id': 1}

        response = self.client.post(url, data_initial, format='json')
        self.assertEqual(response.status_code, status.HTTP_201_CREATED)
        self.assertEqual(response.data, data_expected)
        self.client.logout()

Any help appreciated.

Ok, guys, thanks, it's solved for me. By printing response object I figured out that calendar_id was wrong. Because I use MySQL with InnoDB (maybe have to switch to PostreSQL), the IntegrityError "Cannot add or update a child row: a foreign key constraint fails" caused strange behaviour in the second test. The solution that helped me is to switch in settings.py from InnoDB engine to MyISAM this way:

db_options = "INNODB"
import sys
if 'test' in sys.argv:
    db_options = "MYISAM"

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'callist',     
       'USER': 'test',
       'PASSWORD': 'test',
       'HOST': 'localhost',               
       'PORT': '80',                      
       'OPTIONS': {'init_command': 'SET storage_engine=' + db_options},
    }
}

Will think of switching to PostreSQL. Thanks for those who tried to help.
