Hi I have a form with a file field. In the form validation, I need to validate something in the file, but I see self.request.FILES is empty on first request (the validation one), it only come with the files in the second submit (the save one). So, if the files are right, everything goes ok, but if the files are wrong, I only can detect it too early. Thanks in advance for your help.
