The solution I have found is overriding the save function from the model
class:
class FileUpload(models.Model):
owner = models.CharField(max_length=200,blank=False, null=False)
record = models.FileField(upload_to=path_and_rename)
def save(self, force_insert=False, force_update=False, *args, **kwargs):
if not bool(self.record):
raise ValidationError("Record is required")
super(FileUpload, self).save(force_insert, force_update, *args,
**kwargs)
Is there another way to do it?
Best regards,
Cyril
