from django.core.management.color import no_style
from django.db.models.base import ModelBase

class ModelMixinTestCase(TestCase):                                         
    """                                                                     
    Base class for tests of model mixins. To use, subclass and specify      
    the mixin class variable. A model using the mixin will be made          
    available in self.model.                                                
    """                                                                     

    def setUp(self):                                                        
        # Create a dummy model which extends the mixin                      
        self.model = ModelBase('__TestModel__'+self.mixin.__name__, (self.mixin,),
            {'__module__': self.mixin.__module__})                          

        # Create the schema for our test model                              
        self._style = no_style()                                            
        sql, _ = connection.creation.sql_create_model(self.model, self._style)

        self._cursor = connection.cursor()                                  
        for statement in sql:                                               
            self._cursor.execute(statement)                                 

    def tearDown(self):
