Solve the following python programming problem given the following code:
def test_object_does_not_exist(self) : 
    'If requested obj id does not exist, no action is taken.' 
    req = self.req ('post', '/the/url', data = { 
        'action-doit' : '3', 
}) 
    class MockModelDoesNotExist (Exception) : 
        pass 
self.mock_model.DoesNotExist = MockModelDoesNotExist 
    def raise_does_not_exist(* args, **kwargs) : 
        raise self.mock_model.DoesNotExist 
self.mock_model._base_manager.get.side_effect = req 
    res = self.view (req) 
    self.mock_model._base_manager.get.assert_called_with (pk = '3') 
    self.assertEqual (res.status_code, 302) 

    
    

    Fix the buggy line: self.mock_model._base_manager.get.side_effect = req
