[web2py] Obtaining the download url of uploaded files

[Luther Goh Lu Feng]

I have a simple table that holds uploaded images


========================
db.define_table('image',
        Field('image', 'upload', notnull=True),
)

========================

I would like to obtain the download url for uploaded images. How can I
obtain that in the action, and then render it in the view using
{{=URL}}?

========================
        image_upload_form = crud.create(db.image)
        if image_upload_form.accepts(request.vars,session):
                response.flash = 'Image uploaded'
        elif image_upload_form.errors:
                response.flash = 'Image form has errors'
========================
