Ok so I will write a custom form. I think that I will also write a custom field to do some specific things (for example add a url method to get png ...). I need to understand better the methods :
- contribute_to_class, -validate, validate_full -formfield I found nothing in django's doc, and few examples with google. There are some usuful stuff in "pro Django" book but I'm looking for other doc and examples. In particular, I don't understand how validate(self, field_data, all_data) works (how to handle all_data ?). I would like to find examples or detailled docs on those topics. If anyone could point a link ... Thanks, Alain. On 1 sep, 14:32, Thomas Guettler <h...@tbz-pariv.de> wrote: > Hi, > > Up to now Model Validation is not possible with django.
