class ModelTestCase(TestCase):
    A test case for models that provides an easy way to validate the DB
    contents against a given list of row-values.

    You have to specify the model to validate using the 'model' attribute:
    class MyTestCase(ModelTestCase):
        model = MyModel
    def validate_state(self, columns, *state_table):
        Validates that the DB contains exactly the values given in the state
        table. The list of columns is given in the columns tuple.

            ('a', 'b', 'c'),
            (1, 2, 3),
            (11, 12, 13),
        validates that the table contains exactly two rows and that their
        'a', 'b', and 'c' attributes are 1, 2, 3 for one row and 11, 12, 13
        for the other row. The order of the rows doesn't matter.
        current_state = object_list_to_table(columns,
        if set(current_state) != set(state_table):
            print 'DB state not valid:'
            print 'Current state:'
            print columns
            for state in current_state:
                print state
            print 'Should be:'
            for state in state_table:
                print state
            self.fail('DB state not valid')
