 Custom field transformations
@@ -223,6 +225,8 @@ One approach is to create a custom Django field.
 You can set a temporary data type for a column when it is first loaded and provides a SQL string for how to transform it during the insert into the model table. The transformation must include
 a string interpolation keyed to "name", where the name of the database column will be slotted.
 
+This example loads in the column as the forgiving `text <http://www.postgresql.org/docs/9.4/static/datatype-character.html>`_ data type and then uses a `CASE statement <http://www.postgresql.org/docs/9.4/static/plpgsql-control-structures.html>`_ to transforms the data using a CASE statement.
