    197197A file-upload field.
    199 Has an extra required argument, ``upload_to``, a local filesystem path to
    200 which files should be upload. This path may contain `strftime formatting`_,
    201 which will be replaced by the date/time of the file upload (so that
    202 uploaded files don't fill up the given directory).
     199A ``FileField`` has an extra required argument ``upload_to`` and an
     200optional argument ``filename_normalizer``. The ``upload_to`` specifies a
     201local filesystem path to which files should be upload. This path may
     202contain `strftime formatting`_, which will be replaced by the date/time of
     203the file upload (so that uploaded files don't fill up the given
     204directory). The ``filename_normalizer`` is a function to "normalize"
     205filename from the value provided from file-upload widget. The default value
     206is set to ``django.utils.text.get_valid_filename`` which strips all
     207non-ascii characters.
    204209The admin represents this as an ``<input type="file">`` (a file-upload widget).
