New subject: [PATCH] nevow.static.File directory listing

5 Apr 2004


      ...
Aha! All becomes clear.
...
If there is a better way, I am certainly willing to use it.
Yep, it's much simpler too :)
Although locateChild() is the "official" API for URL traversal,
rend.Page adds some more convenient ways of specifying children. The one
you probably want is so define a child_images attribute on your root
page's class:
    from twisted.application import internet, service
    from twisted.web import static

    from nevow import appserver
    from nevow import rend
    from nevow import static

    class RootPage(rend.Page):

        # Mount the 'images' directory at the '/images' URl
        child_images = static.File('images')

        docFactory = rend.htmlstr(
            '''
            <html>
              <body>
                <img src="/images/TwistedLogoFull.png" />
                <p>Blah, blah, blah</p>
              </body>
            </html>
            '''
            )

    application = service.Application('static')
    webServer = internet.TCPServer(
        8000,
        appserver.NevowSite(RootPage()))
    webServer.setServiceParent(application)


Ok. Cool. That looks nice.
With that example, and unpatched nevow, I still get an error when
trying to browse to   http://localhost/images   (note, no trailing slash)
The error is the same as in my last post ...
File "/usr/local/lib/python2.3/site-packages/twisted/python/filepath.py", 
line 138, in open
    return open(self.path, mode+'b')
exceptions.IOError: [Errno 21] Is a directory
Also... trying to get the Nevow module from anonymous cvs is giving
me an error:
$cvs -d:pserver:anon@divmod.org:/cvs co Nevow
cvs server: cannot find module `Nevow' - ignored
cvs [checkout aborted]: cannot expand modules
Thank you for your time.
