Call SQL function within Model

[Naoko Reeves]

Dear Experts,
I am using postgresql and have field type bytea.
This is an encrypted field
I normally decrypt value with sql function.
I would like to use this function to return value from Django model.
Is this possible? If so could you guide me how could I accomplish this?

Thank you very much for your time in advance.
Naoko

  You probably want to use something like

    https://docs.djangoproject.com/en/1.3/ref/models/querysets/#extra

  to add custom sql expressions to your querysets.
