Jifty::Web::Form::Field::Upload - File upload field

An input field that renders using <input type="file" />. The argument value that the action receives from this field via argument_value in Jifty::Action will be a filehandle, which can be read in the usual ways.

Renders the file upload widget.

The 'value', rendered, is empty so that BLOBs and the like don't get streamed to the browser.

Add 'upload' to the rest of the classes
