    <p>After spending two entire days on this I'm still finding it impossible to understand all the choices and configurations for Comet in Python. I've read all the answers here as well as every blog post I could find. It feels like I'm about to hemorrhage at this point, so my utmost apologies for anything wrong with this question.</p> <p>I'm entirely new to all of this, all I've done before were simple non-real-time sites with a PHP/Django backend on Apache.</p> <p>My goal is to create a real-time chat application; hopefully tied to Django for users, auth, templates, etc.</p> <p>Every time I read about a tool it says I need <em>another</em> tool on top of it, it feels like a never-ending chain.</p> <p>First of all, can anybody categorize all the tools needed for this job?<br> I've read about different servers, networking libraries, engines, JavaScripts for the client side, and I don't know what else. I never imagined it would be this complex.</p> <p><a href="http://twistedmatrix.com" rel="noreferrer">Twisted</a> / Twisted Web seems to be popular, but I have no idea to to integrate it or what else I need (guessing I need client-side JS at least).</p> <p>If I understand correctly, <a href="http://orbited.org/" rel="noreferrer">Orbited</a> is built <em>on</em> Twisted, do I need anything else with it?</p> <p>Are Gevent and Eventlet in the same category as Twisted? How much else do I need with them?</p> <p>Where do things like Celery, RabbitMQ, or KV stores like Redis come into this? I don't really understand the concept of a message queue. Are they essential and what service do they provide?</p> <p>Are there any complete chat app tutorials I should look at?</p> <p>I'll be entirely indebted to anybody who helps me past this mental roadblock, and if I left anything out please don't hesitate to ask. I know it's a pretty loaded question.</p>

    2. CO@jbcurtin Thanks a lot, that's probably the best article I've read. Orbited doesn't seem to be too well-maintained, are there many similar projects? I'm still having trouble knowing if I need to use anything else with that (especially since I want all the messages persistent in a database); like do I still need to know all about Twisted itself?

    3. COI don't think you're going to have much luck employing django to complete this task. The closet thing I could find was `django evserver`. Twisted might be the way to go, in the end comet is just suspending a thread to keep it open. You'd have to kill the entire django life-cycle to accomplish this.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
