Hi.
I did some hacking with twisted.web and woven, just to try and teach myself
how to go about writing a web application using twisted, bearing in mind I
write php in my day job, this was a little hard.
http://thorne.ath.cx:3000/~stephen/wikiexample.xhtml
is the result of my efforts, and you can see it running at
http://thorne.ath.cx:8081/MainPage/
I've got there the original code I started with (using Resource and a fairly
phpish methodology) and what I finished with.
In my little venture back into the realm of twisted, I see the following
lacking in the documentation:
* The varied Views and Widgets are poorly documented, I found myself
inventing what was needed, then going into Twisted/twisted/web/woven/ and
reading widgets.py and view.py - and discovering that they already existed.
* There is very little mapping between "This is how you would do it in a
silly framework" -> "This is how twisted makes it cleaner and easier"
* The pitfalls.
* e.g. For submitting forms and the implicit header "Location:" redirects
which obliterate your post values. (When you have <form action="/Foo/bar">,
but you'll get redirected to "/Foo/bar/")
* the interface to the factories should be written down on a piece of card
and stuck to the monitor. Swapping 'request' and 'model' doesn't help things.
As such, I intend to go through all the views and widgets, and write a small
example piece of code, showing what each of them does, and what
inputs/outputs they take. I also intend to take some php idioms and show a
mapping from them to twisted.
Fortuantely, I've got loads of experience with lore (I recently used it to
typeset a 90+ page tutorial for a camp I'm leading on in 2 weeks,

Please send replies CC: stephen at thorne.id.au as I'm not currently subscribed
