[web2py] sending an image file to client without a temp file

[Calvin]

I was searching for the above functionality and found a solution using 
Flask and StringIO as below (short code snippet attached for convenience). 
Is there a way to do the same with web2py?

#!/usr/bin/env python
# Thanks to Dan Jacob for a part of the code !
from flask import Flask, send_fileimport StringIO
app = Flask(__name__)
@app.route('/')def index():
    strIO = StringIO.StringIO()
    strIO.write('Hello from Dan Jacob and Stephane Wirtel !')
    strIO.seek(0)
    return send_file(strIO,
                     attachment_filename="testing.txt",
                     as_attachment=True)
        app.run(debug=True)
