Django 1.7 Exceptions documentation exceptions.DoesNotExist:

The DoesNotExist exception is raised when an object is not found for the given parameters of a query. Django provides a DoesNotExist exception as an attribute of each model class to identify the class of object that could not be found and to allow you to catch a particular model class with try/except.

Based on above documentation I wrote custom Model Manager:

class CountryManager(models.Manager):
    def get_special(self, *args, **kwargs):
        kwargs.update({'country': settings.ACTIVE_COUNTRY})
        try:
            return self.get(*args, **kwargs)
        except self.model.DoesNotExists:
            self.logger.warning('Unable to find specific object using filter {}'.format(kwargs))
            kwargs.update({'country': settings.DEFAULT_COUNTRY})
            return self.get(*args, **kwargs)

Note that: lines with {'country': settings.ACTIVE_COUNTRY} and with{'country': settings.DEFAULT_COUNTRY} are simplified for this example

class CountryModelMixing(models.Model):
    country = models.CharField(
        max_length=2,
        default=settings.DEFAULT_COUNTRY,
        choices=settings.COUNTRIES,
        verbose_name=_('country')
    )

    objects = CountryManager()

    class Meta:
        abstract=True

class Product(CountryModelMixing):
    name = models.CharField(max_length=40)

and in code when I'm trying to:

Product.objects.get_special(name='abc')

And I'm getting following error:

/opt/src/common/managers.py in get_special(self, *args, **kwargs)
     40         try:
     41             return self.get(*args, **kwargs)
---> 42         except self.model.DoesNotExists:
     43             self.logger.warning('Unable to find specific object using filter {}'.format(kwargs))
AttributeError: type object 'Product' has no attribute 'DoesNotExists'

DoesNotExist does not take an "s":

except self.model.DoesNotExist:
