    FileField subclass Custom Lookups A simple lookup example A simple transformer example Writing an efficient abs__lt lookup A bilateral transformer example Writing alternative implementations for existing lookups query. We then return a tuple containing the generated SQL string and the parameters. A simple transformer example The custom lookup above is great, but in some cases you may want to be able to chain lookups without duplicating functionality already in Django. We will start by writing a AbsoluteValue transformer. This will use the SQL function ABS() to transform the value before comparison: from django.db
