ok don't know what typo I made yesterday but it works now, maybe
backslash in path. Thanks.
for you who want to know how:
def get_path(instance, filename):
return instance._folder
My model:
class File(models.Model):
type = models.CharField(max_length=10)
the_file = models.FileField(upload_to=get_path)
def __unicode__(self):
return self.file.name
def save(self, force_insert=False, force_update=False):
self._folder = "new_folder/"+self.the_file.name
super(File, self).save(force_insert, force_update)
