When you start your application:

Now I've just deluged the poor user with lots of factory start and
stops. All I want is normal HTTP style logs. Twisted's logging
infrastructure has its place, but it is not quite ready to produce
user friendly output for a simple utility.
That's probably a bug/feature request.
Or, even better, create an Application object and use twistd(1) to start
your service. Using twistd(1), you have a choice to daemonize your process
or not.
Great, now the user has to edit a tac file just to configure the
thing. I'd rather them be able to type "tape" and not have to worry
about twistd -ny some.tac. I use tac files a lot, but they don't make
much sense for simple utilities. It sucks that it's either/or with
Twisted applications.
I'm assuming "tape" is your application?
These sessions helped to reinforce for me the need to repeat this frequently
for our users: if Twisted is doing something which confuses you but seems
wrong, please go ahead and file a bug on twistedmatrix.com.
This mailing list should be indexed by Google as well. I do plan to
file the bugs we find here as well.
* The only way to stick something in the tree at an arbitrary location
seems to be to walk the tree to that spot, creating dummy locations as
you go.
Override locateChild
What is that? I see no such function:
Not in IResource:
http://twistedmatrix.com/documents/current/api/twisted.web.resource.IResource.html
Not in the server.Site:
http://twistedmatrix.com/documents/current/api/twisted.web.server.Site.html
grep -r doesn't show it in the twisted/web or any child directories.
Not even in SVN trunk.
It's in nevow's appserver/resource sub-classes, not in t.web; not that
this helps you of course.
Basically, you're right - the resource dispatch in t.web is, to say the
least, difficult. Sadly, you need to change both the http server,
channel and request code to alter it (which is what Nevow does)
I find it extremely weird coming from several other web
frameworks.
Twisted initially seems very different, no matter what framework you came
from.
I grok Twisted just fine. This may be my first post to twisted-web,
but I've been hacking on and around Twisted for some time. Even
Apache doesn't work this way. I can tell apache that my proxy is at
/some/url/over/here and it will work. It will return 404s for the
intermediate URLs. Because Resources only have immediate children and
paths are only dealt with in single element pieces, there doesn't seem
to be a way to do this in Twisted Web. It feels weird that the tree
must be complete. It feels weird that paths are dealt with in tiny
sections.
I believe the eventual plan is to have t.web use the nevow appserver &
resource model, with backwards compatibility stubs.
* Related to the above, the handling of foo vs. foo/ is pretty
confusing. foo/ is considered the '' child of foo. This is pretty
yuck to me. Unfortunately, I don't have any creative suggestions
about how to do it better right now.
addSlash = True
This does not exist in Resource or in server.Site. What am I missing?
It's not mentioned in the docs either.
Again, that's a nevow thing. This does have an equivalent in t.web - set
isLeaf = True
Basically, you want the nevow resource model. Sadly, that loses you the
easy render_METHOD helpers, though you can easily re-add them by hooking
renderHTTP and dispatching on a base class.
To the devs: If there are a list of tickets for bringing the nevow stuff
into t.web, I'd probably be able to spend some time working on them.
