Klein is a little bit higher level and helps you build the scaffolding necessary to assemble a site out of a bunch of objects.</div><div><br></div><div>However, I think Phil's correct insofar as he recommends that Django might be better suited towards the web application parts of your problem. mod_wsgi, though? No need for that :).</div><br><div>Another combination, the one I would recommend, would be Django running under Twisted. Twisted's WSGI container can run Django just fine (although it will need a little help - <<a href="https://github.com/clemesha/twisted-wsgi-django">https://github.com/clemesha/twisted-wsgi-django</a>> - since Django isn't really a WSGI app, it's a WSGI-plus-some-stuff app).</div><div><br></div><div>Twisted (mostly) a web <i>server</i>, for doling out resources, where as Django is (mostly) a web <i>framework</i> for developing web applications.</div><div><br></div><div>You can use either for either, of course; Twisted has a web app framework and Django has a built-in web server.</div><div><br></div><div>Although Twisted's web-frameworky bits (twisted.web.template, adbapi, cred, guard) are encouraged more for production use than Django's web-server-y bits (runserver.py), if you're developing a reasonably standard web app that just needs to manipulate a little database state, Django will be a lot easier to work with, not to mention fantastically documented.</div><div><br></div><div>The web-frameworky bits of Twisted tend to have advantages when one is making web interfaces to things which <i>aren't</i> simply database-backed HTML applications. For example, a web interface which allows you to view live data-flows, or controls some kind of hardware. Or, for developing the web interface for something which has a model that might also be accessed by other protocols, like IMAP, DNS, NNTP, and so on.</div><div><br></div><div>For example, Twisted doesn't have an ORM of any kind (since your state might live in any kind of database, or no database at all!), and it's still a bit of an open question in the community what the best way to interact with database-backed state from Twisted is. By contrast, Django has an ORM that can automatically generate a web interface to allow administrators to manipulate any Django model in your application.</div><div><br></div><div>Plus, if you use Django to develop your application but run it within a Twisted WSGI container, you can leverage the power of Twisted at any time. Itamar has even recently released a tool to help you do this almost automatically, Crochet: <<a href="http://blog.futurefoundries.com/2013/05/announcing-crochet-07-easily-use.html">http://blog.futurefoundries.com/2013/05/announcing-crochet-07-easily-use.html</a>>.</div><div><br></div><div>Hope this is helpful!</div><div><br></div><div>-glyph</div></body></html>
