TG2.1, sharing DB with TG1.1

2010-03-21T21:24:20Z

Hallo there!
I've began exploring TG2.1 today after years of 1.x, and I like it.
It would be nice to start writing new modules for an existing business
application, currently running under TG1.1.
The current app has been in production since 2007, and porting the
whole baby is unthinkable. Besides, I'm quite satisfied by its

Tracking DB connection usage

Hi all,
In a TG2 app, I have SQLAlchemy configured with a pool size of 30
(overflow 30), and the Paste HTTP server configured to run with 50
threads. There is a limit of a maximum 50 concurrent connections
coming to the server.
However, I am regularly seeing SQLAlchemy TimeoutErrors with no
connections available in the QueuePool. It seems that there should

Great - I've got a threadlocal connection set up and it works
perfectly.
Thanks Diez!

Thanks again for the clarification here.. I thought I would losing my
mind for a moment. So, yes, it becomes obvious that controllers that
are simply class attributes and behave as such, and controllers called
as part of the a _lookup method are normally instantiated objects that
are created and destroyed as appropriate to the request (per _lookup

That's a different thing, yes. Maybe I was the dense here - but the OP
asked (IMHO) for the "normal" controller hierarchy & it's objects,
which (with the exception of the root) aren't instantiated after
initial load. Simply because they are *class*-attirbutes.

Thanks Diez. After a re-read of this thread, I am understanding this more
clearlt... just a weird situation to understand. Additionally, if I look at
the sample code:
class BlogController(BaseController) :
@expose()
def _lookup(self, year, month, day, id, *remainder):
dt = date(int(year), int(month), int(day))

Please don't hijack other threads & just change the subject. This is
very confusing for those who prefer their mails being threaded.
Well, the disadvantage is pretty much what you say yourself - the
browser doesn't change the url. This might be desirable, but can also
cause problems if the user hits "reload" and is asked if she's sure

No.
The only controller that currently gets instantiated on a per-request-
base is the root-controller. And I don't read anything else from the
_lookup/_default docs either.
HTH,

Re: [TurboGears] Re: Install TG 2.1 on Centos issues

2010-03-16T04:26:03Z

And, as you can now see at that ticket (
[link] ), I've proffered up a fix that will
(hopefully) make it into the next release. Especially since it was me that
introduced the bug. Sorry about that.

Re: [TurboGears] Where is the TG2.1 document?

2010-03-18T23:34:35Z

The linked headings here [link] are
no longer underlined when I mouseover them. Of course, my mouse pointer
turns into a hand, which means the headings are a link, but I still bet
other people are going to fail to find the documentation because it's
hard to know those headings are the only links into the documentation.

cherrypy.HTTPRedirect vs. cherrypy.InternalRedirect

2010-03-18T22:47:14Z

Hi,
Can I have a naive question? Is there is any hidden catch in using
cherrypy.InternalRedirect instead of cherrypy.HTTPRedirect (in deployed
application behind apache, https. ...)? I'd like to use the
InternalRedirect because it hides (at least in the navigation bar) the
url parameters ...
I'm using TurboGears 1.0.8.

Diez,
Just so that I am reading you (and this thread) clearly here about
controller instantiation... all controller classes are instantiated as
objects on a per request basis.. yes? Therefore, if I have a sub
controller with an __init__ that does some work needed, common to all
my controller class methods, it can assign local (self) attributes in
