[Django]-Django: Uploaded file locked. Can't rename

5👍

✅

I think you should look more closely at the upload_to field. This would probably be simpler than messing around with renaming during save.

http://docs.djangoproject.com/en/dev/ref/models/fields/#filefield

This may also be a callable, such as a
function, which will be called to
obtain the upload path, including the
filename. This callable must be able
to accept two arguments, and return a
Unix-style path (with forward slashes)
to be passed along to the storage
system. The two arguments that will be
passed are:

My other answer is deprecated, use this instead:

class File(models.Model):
    nzb = models.FileField(upload_to=get_filename)
    ...
    def get_filename(instance, filename):
        if not instance.pk:
            instance.save()
        # Create the name slug.
        name_slug = re.sub('[^a-zA-Z0-9]', '-', instance.name).strip('-').lower()
        name_slug = re.sub('[-]+', '-', name_slug)

        filename = u'filess/%(2)s_%(3)s.nzb' % {'2': instance.pk, '3': name_slug}

        return filename

As of 1.0, upload_to can be callable, in which case it is expected to return the filename, including path (relative to MEDIA_ROOT).
