Kenneth,

Why don't you doc it somewhere for future queries and for newbies switching?
Also have you see any tangible performance improvement?

Have you properly configured your  MEDIA_URL to point to your Tornado
server instead of localhost:8000. I haven't made any test about
Tornado performance on serving statig files, but on production our
actual configuration with CherryPy in WSGI mode involves a nginx
server acting as a reverse proxy and serving the media files.

I use the configuration without nginx pointing directly to the WSGI
server just to make sure that all the media points to right server.
That is, that I have write all my media files as
{{MEDIA_URL}}/img/.jpg and so on.

Hope it helps!

Re: Running Django on Tornado's HTTP server

[Brian]

Thanks ... this link pointed me in the right direction.

Should I be able to serve up admin media using just Django and
Tornado?  If so, I haven't found the right combination of paths / urls
etc. in settings.py to get that working. The Tornado doc describes how
to "serve static files from Tornado by specifying the static_path
setting in your application" - so it sounds like it might eventually
work? The Tornado blog demo is one example, but I couldn't get that
approach working with my Django app.

I now have nginx serving up the Admin files, running alongside Tornado
and Django. My Admin Site formatting and layout looks fine with that
setup.

Re: Running Django on Tornado's HTTP server

[fruits]

media files for admin is handled by the django dev server. So when you
change the server, you have to serve admin media file yourself.

Re: Running Django on Tornado's HTTP server

[Brian]

I have a small Django app under development and was able to get this
running using the github update. My app runs and is very responsive
with Tornado.

Some of my admin site layout is out of whack, but it may be my
settings or my bug.  Formatting and CSS I created on my own looks good
(e.g. graphics and tables created using the Google Visualization API.)
My app is able to go out onto the web, get files downloaded through
Tornado - it feels fast ...

It's terrific to have a Python-based server that could work in both
development and production. (Tornado installs/runs fine on a Netbook
with Ubuntu!)

The real-time / asynchronous capabilities look great. Any way Django
apps can take advantage of that functionality?

Thanks for open sourcing this!

We're acually using Cherrypy, so it would be quite easy to test and
check the performance. We'll post any issues we found.

Running Django on Tornado's HTTP server

[Bret Taylor]

I am one of the authors of Tornado (http://www.tornadoweb.org/), the
web server/framework we built at FriendFeed that we open sourced last
week (see http://bret.appspot.com/entry/tornado-web-server).

The underlying non-blocking HTTP server is fairly high performance, so
I have been working this weekend to get other frameworks like Django
and web.py working on Tornado's server so existing projects could
potentially benefit from the performance. To that end, I just checked
in change to Tornado that enables you to run any WSGI-compatible
framework on Tornado's HTTP server. You can find it in a class called
WSGIContainer in our wsgi.py:

http://github.com/facebook/tornado/blob/master/tornado/wsgi.py#L188

You will have to check out Tornado from github to get the change; it
is not yet included in the tarball distribution.

Here is a template for running a Django app on Tornado's server using
the module:

import django.core.handlers.wsgi
import os
import tornado.httpserver
import tornado.ioloop
import tornado.wsgi

def main():
os.environ["DJANGO_SETTINGS_MODULE"] = 'myapp.settings'
application = django.core.handlers.wsgi.WSGIHandler()
container = tornado.wsgi.WSGIContainer(application)
http_server = tornado.httpserver.HTTPServer(container)
http_server.listen()
tornado.ioloop.IOLoop.instance().start()

if __name__ == "__main__":
main()


I have only done very basic tests using the new module, so if any of
you are interested and start using Tornado with your Django projects,
please let us know what bugs you find so we can fix them. Any and all
feedback is appreciated.

Bret
