Django test table is not created

I have a django website using latest version of django(1.7.4 as of now). When I run my tests, they all fail because django complains one of my models doesn't exist in the test database. The error is below:

File "./manage.py", line 10, in <module>

django.db.utils.ProgrammingError: (1146, "Table 'test_app.user_detail' doesn't exist")

The strange thing is that my model is defined as:

class UserDetail(models.Model):
    class Meta:
        db_table = 'user_detail'

    user = models.ForeignKey("auth.User")

EVERY other model (from all apps) in my settings.py are created. For some reason this one app is the only one where the model doesn't exist on the test db. Is there anything else i'm doing wrong here? Why is this one table not being created?
