Question

I need to write following query

SELECT id, name, (

                     CASE WHEN photo =  ''
                     THEN  'DEFAULT_PIC'
                     ELSE photo
                     END
                  ) AS image
       FROM admin_category

Can ORM handle it ??

Answer 1

It can be done in model.

class Category(models.Model):
    ...

    @property
    def image(self):
        return self.photo or u'DEFAULT_PIC'

# usage
category.image
