Question about file uploading

[riteshn]

Hi

I have a form with a file field. In request handler, I am doing the
following:

attachment = req.files[form.attachment.name]
data = attachment.read()
if len(data):
print(type(attachment))
print attachment.type
open(os.path.join(ATTACHMENTS_DIRECTORY,
attachment.filename), 'w').write(data)

>>>>

It throws up a traceback like: http://paste.pocoo.org/show/111558/

Though according to the doc at http://werkzeug.pocoo.org/documentation/wrappers,
it should have the property.

Similarly, attachment.data does not work but attachment.read() does.

What I might be missing?

Looking at the Werkzeug source at that revision [1], seems this is a
documentation bug in Werkzeug. The actual attribute is "content_type",
and "content_length" also exists. This seems to be the same in tip. I
have no idea if the docs have changed for the newer unreleased versions.

"data" I am not sure about, are you getting the same exception?
