I don't understand, sorry :$. Do you care to explain a little bit
more? Or could you give an example?

I'm using the admin interface btw.

You added a custom field clean method to your model definition.  This has no effect, as models (currently) don't support validation or cleaning.  Validation/cleaning is done for forms, so you need to add your custom field clean method to the form used to upload your file.  Admin supports this by allowing you to specify the form it is to use for a model:
