[TurboGears] Re: Is there a convenient solution to object names in urls?
2006/1/30, Soni Bergraj [EMAIL PROTECTED]: I'm looking for a more convenient approach to this same problem myself too. I'm especially after a way I can do this: /persons/FooBar/addresses/Postal/edit As it is, I have to do a backflip or two in the default() handler in order to dispatch to the correct method. That really gets ugly... web.py (http://webpy.org/) offers a solution based on regular expressions. Works nicely so far:) I remember reading somewhere about use of Routes [1] with CherryPy. I think the addition of Routes to TG would be *very* welcome :) [1] http://routes.groovie.org/ -- Ksenia

[TurboGears] Do any of the alternate template systems work with widgets?
Hi, I am using windows XP as my development system. The endless loop bug with extends in Kid is driving me crazy. Actually, it seems like Kid needs the all the templates to be in the same directory. Documentation seems insufficient on this point. I want to provide a standard set of forms and allow people to modify the theme behind it. I am almost ready to release version .1 of my CMS. I want it to sit as much as possible on top of Turbogears. Otherwise, I might as well roll my own framework, which would be stupid. I would prefer to use KID but I have to get this thing out since I have projects that depend on it. Thanks Alvin

Unfortunately I'm not sure how to actually get the recipe working and it was abandoned as hacking a custom default method was quicker to get working. I'm still a big advocate of routes. I'd also like to know the actual reason why the decorators no longer work when using the method used to make routes work... I know that I return exposed functions in my other default methods and the decorator works. Lee

[TurboGears] Re: log to screen in 'development' mode
Max Ischenko [EMAIL PROTECTED] writes:
Hello,
TurboGears startup.py contains the following code:
isdev = cherrypy.config.get('server.environment') == 'development'
if isdev:
# configure logging module to log to sys.stdout
OTOH, there is server.log_to_screen setting.
Shouldn't logging configuration be dependent on that setting instead of
server.environment?
After all, it's a bit confusing when I set server.log_to_screen to False and
server.environment is 'development' and I still see the log on the console.
Maybe an AND for the environment but with an obligatory setup for the config
option.

[TurboGears] Re: kid templates with accented characters
2006/1/30, Petro Verkhogliad [EMAIL PROTECTED]:
Thanks that does help. The only thing that worked is the following:
unicode(book.author.decode('latin1').encode('utf8'), 'utf-8')
a little hackish. but it works. i'll have to clean up the output before
it gets to kid templates.
I do think that Kid's inability to use non-ascii-encoded strings is a
bug. Right now Kid accepts either unicode objects, or ascii-encoded
strings. IMHO when it comes to strings, Kid should decode them using
document's encoding (latin1 in your case).

You have to pass a Unicode string to Kid if it may contain non-ascii character. Also, you you pass your SQLObject model instances to Kid you may declare corresponding field as UnicodeCol so that it will be encoded automatically.

[TurboGears] DynamicSelectField widget
http://trac.turbogears.org/turbogears/ticket/475
Comments and discussion please. I think that this is a good addition
to the base widgets. If not then I'll add it as a recipe for a custom
widget on the wiki.
(Copied from the ticket)
Sometimes you don't know what a SelectField's options are going to be
before you .insert() it and changing the options on the fly isn't
threadsafe.
Attached is a patch with a new widget called DynamicSelectField?. It's
essentially the same as a normal SelectField? except it pulls out it's
options from widget_value on .insert().
Examples:
div
${testwidget.insert(value=(3, [(1,Apple),(2,Banana),(3,Pear)]))}
/div
div
${testwidget.insert(value=(2, [(1,Audi),(2,VW),(3,Ford)]))}
/div
The first argument in the value tuple is the value of the option you
want to be selected and the second is a list of tuples containing the
options and their respective values and text.
With this method the data can still be passed when the widget is
nested in a Form Widget (or subclass thereof).

The trick is to specify joinColumn:

par_category = ForeignKey('Cat')
category_name = UnicodeCol(alternateID=True, length=30)
Note that joinColumn must be the database column's name, not the

[TurboGears] Widgets redux, call for testers
Hi, I the last few days I've been working on an API cleanup (not yet finished but mostly so) for the widgets system. I tried to make them intuitive to use, to customize (very simple templates, compare them with what TG is actually using) by moving a lot of logic from templates to where it belongs and provide good default widgets for forms managing. What I mean with the last thing? That for example you get: SingleSelectField MultipleSelectField RadioButtonList CheckBoxList they all work in the same way: - SingleSelectField and RadioButtonList for a single choiche - MultipleSelectField and CheckBoxList for multiple choiches the only difference stands in their lookfeel. I would like interested people to try them, I've tried to keep them compatible with the old ones but some things had to be changed. You can play with my work using a small TG project I've attached here: http://trac.turbogears.org/turbogears/attachment/ticket/490/NewWidgets-0.5.tar.gz?format=raw You find forms widgets inside forms.py. :-) Give it a try and report here your opinions, I'm going to have few time to do any other work.

without question... (I *think* the current widget may take a callable
for the options list, which is the current mechanism for handling
this, but that's not always as pleasant.)

(Copied from the ticket)
Sometimes you don't know what a SelectField's options are going to be
before you .insert() it and changing the options on the fly isn't
threadsafe.
Attached is a patch with a new widget called DynamicSelectField?. It's
essentially the same as a normal SelectField? except it pulls out it's
options from widget_value on .insert().
Examples:
div
${testwidget.insert(value=(3, [(1,Apple),(2,Banana),(3,Pear)]))}
/div
div
${testwidget.insert(value=(2, [(1,Audi),(2,VW),(3,Ford)]))}
/div
The first argument in the value tuple is the value of the option you
want to be selected and the second is a list of tuples containing the
options and their respective values and text.
With this method the data can still be passed when the widget is
nested in a Form Widget (or subclass thereof).

Hi Michele, Cool, just a nit: Could you use and underscore instead of '-' betwen widget.field_id and value? I don't like to see price-2 as a radio option. Underscores make it clear (in the HTML/javascript/css) that we are talking about strings. I told you this was a nit =) Cheers.

WARN : if you use server side validation, the validation is done against
values
provide during widget's construction (as paramater or through the validator).
I updated my example app to show how you use dynamic options.
http://trac.turbogears.org/turbogears/ticket/490
For a single field we should use the validator provided if any (if it's
not there I try to add a good default), for multiple field it's wrapped
inside a ForEach validator that returns a validate list (you can also
pass a list as default at constructor) to you method.
I'm not using OneOf since it expects to be inizialized with values and
you will not be able to change it dynamically (threadsafety), anyway
for these widgets the input value will always be one of the possible
choiche so the real use of a validator in that case is just the
conversion from/to python, so I can't see any problem.
On the other hand I don't except someone so crazy to change a option
list to be totally dirrent from the default one.
I mean, if you construct with:
options = [(1, python), (2, java), (3, ruby)]
you will probably add or remove some options but not provide a totally
different thing like:
options = [(cool, python), (2, java), (again, ruby)]
that's mixing string and int values, if someone is going to do it I
would like to take a look at its controller method. :-)

because there are some good suggestions for API cleanup ongoing from
David Bernard and Michele Cella. Now is really the last chance to do
that kind of cleanup.
I'd rather not combine the value with the set of options. You should
be able to pass another keyword to insert() to hold the options list.
And, the main select widget can probably support both styles of
working: up-front definition and render-time definition.
Yes, that's exactly how I've done it.
Any widgets can provide additional options using a constructor argument
(options) and the same argument at render/insert time.
For a selection widgets those options are managed as the possible
choiches.

For example a simple hub.commit at the tg-admin shell gives me: hub.commit bound method AutoConnectHub.commit of turbogears.database.AutoConnectHub object at 0x012BAA50 I just tried this on my PowerBook, quite possibly on the same project you're using (or at least one that I know you were recently working on :). For me, hub.commit() worked fine for adding a new record. I had debug=1 on my dburi and I saw the INSERT happen, and the COMMIT happen on the same connection. If you look at hub in your shell, you'll find that it's a PackageHub. When you do hub.commit, you're actually talking to the AutoConnectHub that's responsible for doing the work (PackageHub has a __getattr__ that delegates to the AutoConnectHub underneath). So, this may be related to my other problem, which is that on my Ubuntu Laptop I can't use notrans_ to connect to a mysql database, because it is not getting stripped off. (Ticket #346). Make sure that hub, when displayed in the shell, is in fact a PackageHub. Just to confirm something else: you are running tg-admin shell from the top level directory of your project, right? It's worth making sure that the config that's coming through is the one that's desired. You can always run cherrypy.config.get() statements to see if sqlobject.dburi is what you'd expect. Kevin

Ideally we could split the Container caching system into a small bit of middleware to make to make it easier for all our uses, it's only a few files. It's also worth noting that in Perl, HTML::Mason (Myghty's a port of it) uses Cache::Cache. That is, the Perl folks have a Cache library they can plug-in to other apps/webapps. Mike Bayer (creator of Myghty) has indicated he has no problem with this, as long as the Cache library doesn't become too generic as that made Perl's Cache::Cache a bit of a hassle. - Ben

Earlier today, though, Christian linked to a WSGI session handler, so I guess there is something out there. There's lots of things out there for sessions; I think this is a relatively minor point, since RhubarbTart should be adaptable to any WSGI session setup, and all it takes to WSGIify a session library is very minor glue. The only session middleware I've really looked at is flup, and there are some problems with it (mostly that the session is loaded on every request, not on demand). Paste's built-in sessions are also fairly crude. But stuff is out there, and how it is integrated or what is chosen isn't dependent on RhubarbTart. Generally speaking the design provides more free variables for best-of-breed selection. No one piece is critically central (except for the WSGI protocol, but that's a protocol, not an API). Even Paste is used in relative minor ways -- the imports are all basic utilities (e.g., parse form variables), or applying a default (and optional) set of middleware to form the typical featureset of a framework. I think additionally that the growing work and number of contributors in TG makes it critical that there be more internal decoupling, with possibly differing release schedules. Also, regarding stability, Julian has been adding very good test coverage for RT, so I think it will be quite stable. Testability is aided by the fact that RT is very small. Here's my philosophy on stuff like this: I aim for TurboGears to be best-of-breed. The definition of best-of-breed will change over time. (It'll also vary from person to person, but there's not much I can do about that.) As the best changes, I'd like to see TurboGears change with it. Of course, changes need to have reasonable migration paths and all of that, which is the primary limiting factor. But, the bigger the win, the easier it is to justify a slightly more painful transition. We talked about this stuff some in a private email. I didn't propose anything before 0.9, except hopefully some changes so that applications written against 0.9 won't require major updates (maybe any updates) to work with a possible future TG+RhubarbTart combo. My experience with CherryPaste showed a couple different problems: * Identifying the base of the application. request.app_url is really easy to support (and RhubarbTart includes that). I think there was a proposal about an additional attribute on controllers (is_root_app or something), and that would also be easy to support. I'm baffled how tree.mount is supposed to be used, though I suspect it will be hard to support. * Serving static files. Static file serving as a filter seems rather weird to me. Ideally, I'd like to see: static_dir = os.path.join(os.path.dirname(__file__), 'static') class Foo: static = turbogears.StaticDir(static_dir) # or maybe, for using pkg_resources: static = turbogears.StaticDir(__name__, 'static') I don't know what's considered best practice right now, but CatWalk's registering of static-file-related configuration when you get the index page was particularly hard to deal with. * Imports of CP HTTP-related exceptions, and cherrypy.request/response. These are fairly trivial, since changing cherrypy to rhubarbtart will mostly work (and whatever differences are there can and should be fixed). If TG insulated this (e.g., you import turbogears.request), then applications might require zero changes. RhubarbTart could also provide a cherrypy module for backward compatibility, but I'd really rather not (unless perhaps it was explicitly enabled by the app and spewed warnings). * Filters. CP-style filters could be implemented in RhubarbTart, but I'd rather just not. The filters in TG could be reworked or have extra interfaces to be phrased as WSGI middleware. I think the actual application-facing interface to things like Identity don't need to be changed, so this might not be an issue. Since TG uses decorators more than filters (for app-visible APIs), I think this is mostly OK as-is. There might be other aspects, but those are what I hit. I think most of these changes have

[TurboGears] cElementTree 1.0.5 for windows requires a compiler?

Or put some sort of Hacker Page a là vserver ;) (http://linux-vserver.org/Hacker+Page). I just turned on the account manager plugin again so that people can register. People had reported that they weren't seeing their accounts become active immediately, which would be the primary concern there, but let's give that another try. If all goes well, I may then make all updates require authentication. I still have a little polishing to do (mostly in the login screen), but I'm going to be using openid for authentication in front of trac: http://trac.pythonpaste.org/ You can get openid accounts from a few places; myopenid.com and videntity.org seem the best options right now (videntity has more features). This way I won't have to handle user management at all. This doesn't stop all spam necessarily, but I assume it will stop it until openid becomes popular ;) Hopefully complimentary trust-based systems will also emerge before that happens. Plus you get single-signon, which doesn't matter yet (single-signon only works if sites use it, and not many use openid yet) -- but if openid catches on in open source circles that would be enough to provide real utility to users. I'm planning on leaving ticket modification open, but closing wiki modification and ticket creation. (I'd actually prefer a simple/flatter system than a wiki for document contributions, so I'm mostly trying to ignore Trac's wiki.) -- Ian Bicking / [EMAIL PROTECTED] / http://blog.ianbicking.org
[TurboGears] Re: cElementTree 1.0.5 for windows requires a compiler?
Ronald, I ran into a similar issue with cElementTree. In my case, it was asking for the .Net compiler. I found that running setup.py install (rather than setup.py develop) on the SVN code fixed the problem. Sean
[TurboGears] combined scgiserver + xmlrpcFilter?
I'm running the following bit of code: from cherrypy._cpwsgi import wsgiApp from paste.util.scgiserver import serve_application if useScgi: cherrypy.server.start(initOnly=True, serverClass=None) serve_application(application=wsgiApp, prefix=/, port=4080) else: cherrypy.server.start() Adding xmlrpcFilter to the mix fails when useScgi == True. Any ideas on how I might get a CherryPy application working with scgiserver + xmlrpcFilter?
[TurboGears] Re: A couple of database puzzles
For me, hub.commit() worked fine for adding a new record. I had
debug=1 on my dburi and I saw the INSERT happen, and the COMMIT happen
on the same connection.
If you look at hub in your shell, you'll find that it's a
PackageHub. When you do hub.commit, you're actually talking to the
AutoConnectHub that's responsible for doing the work (PackageHub has a
__getattr__ that delegates to the AutoConnectHub underneath).
So, this may be related to my other problem, which is that on my
Ubuntu Laptop I can't use notrans_ to connect to a mysql database,
because it is not getting stripped off. (Ticket #346).
Make sure that hub, when displayed in the shell, is in fact a PackageHub.
It is definitely seems to be. Help(hub) shows PackageHub information
Just to confirm something else: you are running tg-admin shell from
the top level directory of your project, right?
Absolutely. Anything else causes problems ;)
It's worth making sure
that the config that's coming through is the one that's desired. You
can always run cherrypy.config.get() statements to see if
sqlobject.dburi is what you'd expect.
I've attached the output of an interactive session where I get the
dburi from cherrypy.config.get and try some database connection stuff.
For some reason that I can't quite figure out the ?debug=true link
seems to work here, where it did not on my computer at home. I'll
check into that later tonight.
