[TurboGears] Presentation of TG
Since the begining (5 years) I'm following the different presentations held at the Fosdem (www.fosdem.org). (For those who don't know this is the major event discussing about Open Source Software in Belgium) This is a 2 days (and totally free) event that attract people from all around the world. The next session will be in February 2006 and I would like to see a session on Turbogears. Several projects have seen their comunity increased after the Fosdem. Unfortunately, the dates are the same as for the PyCon in USA... It will not be possible to convince Kevin to be at Fosdem (already tried). Thus we have 2 options: 1) someone is ready to make it (skills to talk in public and good skills of TG) or 2) I do it my self. small remark: all speech must be in English. For the 2), I don't have problems to talk in front of +-400 people in English (and I'm playing with CP since 2.0, and I've made ProjectMgt (but it's quite simple), ...) but then, I'm looking for 1 or 2 who can help me to make a good presentation.

[TurboGears] byPagename again
I'm just starting with TG and am attempting to follow the tutorial by hand. My Page objects seem to lack the byPagename method. I have created the Frontpage object and get the following when using tg-admin. eg C:\Tmp\wiki20tg-admin sql sql Using database URI sqlite:///C|/tmp/wiki20/wiki20_sqlite CREATE TABLE page ( id INTEGER PRIMARY KEY, pagename VARCHAR(30), data TEXT ); C:\Tmp\wiki20tg-admin shell Python 2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)] on win32 Type help, copyright, credits or license for more information.

[TurboGears] template performance question
Hello from a TurboGears newbie. It's cool! I have a question about performance of template processing I tried an informal speed comparison of Kid vs. Cheetah in my TurboGears test app. Using Cheetah, I found that the total time spent in request handling is 7 times faster than using the equivalent Kid template (0.40 seconds vs. 3.06 seconds). Is this expected? Are there any tricks to get Kid to go faster? I think the design of Kid is nice and elegant but it looks like performance would be an overriding factor for me. My test application runs under mod_python. Each request fetches 350 rows from SQLite and produces an HTML table with 3 data fields displayed per row. (If the answer is OK so use Cheetah then, I'll have another question about how Cheetah can be interfaced with CherryPy, given that I want to send the response incrementally to the web client. Cheetah has a callback model (using the trans parameter to respond()) while CherryPy expects the page handler to return an object (cherrypy.response.body) over which CherryPy can iterate. It is not obvious to me how these models can be plugged together.) Thanks for any comments or advice, Jonathan

[TurboGears] how to add a function to std ?
following the documentation (http://www.turbogears.org/docs/gettingstarted.html#predefined), we see how to add a variable. My question is: How to add a new functions (with input parameters) into std ? Let's take an example: I would just have a simple function that will return a text if the condition is true: something like: def conditionaltext(cond,text): if cond: return text else: return None The objectif is to have template with tables like: table tr py:for=i,data for enumerate(datalist) py:attrs=class=std.conditionaltext(i%2,'odd') td.../td /tr /table Thanks William --- http://www.opensource4you.com

[TurboGears] Identity: delete cookie on browser close
Hi, I'm just playing with the identity part of TurboGears and found that I don't know how to set the identity cookie to last only until the browser is closed. Reading some code I found identity.session.timeout, but setting this to 0 just invalidates the login cookie inmediately. Have I missed some obvious way to do this?

I don't know if this is true of a 'production' environment or not, but if Cheetah makes no distinction maybe this has something to do with it. Or it might be a dead end. -- Things fall apart.

[TurboGears] Re: Choice of video capture software and medium.
Have you tried VLC by any chance? It may not work with the codec that I've used for this incarnation of the video. I'm not sure, but VLC plays an awful lot of files. VLC in their features list does not mention QuickTime, so I will assume it uses the same technology that mplayer does - that is, it utilizes emulation of Windows codecs under foreign systems. Again, that isn't going to cut it for my loverly 64-bit system. Experimenting with mplayer-bin under Gentoo it seems to work, but suffers from interesting problems due to linking against odd library versions. (For example, mine is unable to deal with spaces in names, no matter how quoted or escaped I make it. ;)

No, you haven't missed anything - it isn't possible right now without changes to the identity code.

[TurboGears] unicode parameters
Hi, Is it possible to configure TurboGears so that my controller functions get its parameters as unicode strings. Right now controlers return a dictionary with unicode values and after Kid I got properly utf-8 encoded HTML. But the input from forms on the page is returned as uft-8 encoded strings that I have to manualy decode. This is rather not consistent. Do I miss some obvious way to do this?
[TurboGears] Re: Identity: delete cookie on browser close
This raises an interesting point: I think the Identity framework should have separate time-out values for the cookie and the identity session. I think the cookie should default to not having a time out, hence it will be deleted when the browser quits. The identity session will still have a 20 minute lifetime. There are a number of other little tweaks I want to add to the Identity framework's: * Ability to specify the host and path for the cookie * Ability to tie a session cookie to the visitor's IP address * Adding the current identity to the variable provider for template access I got distracted with other work this weekend, but I'd like to get these features included in the next few days.

I don't believe you need to enable the EncodingFilter as TG should

class, try putting
decodingFilter.on = True
in your dev.cfg file. Hopefully this works!

[TurboGears] Re: Identity: delete cookie on browser close
Jeff, I think I see where you are going with the separate timeouts - that way the login expires when the browser is closed or the session times out. What do you think about resetting the session timeout on each request? That way the timeout really becomes an idle timeout. This is how banks handle sessions and it seems to strike the right balance between security and convenience. Can we also add a checkbox to the login form along the lines of remember my login and then adjust the timeout accordingly? I would like to be able to set things up so logins expire after ~10 minutes of idle time (or when the browser is closed) if remember login isn't checked, and expire after some really long period if it is.

[TurboGears] Getting Started in Docs page
Hi, It was such a long time since I have read any of the docs for TurboGears that I decided to touch on it in my insomniac hours. Under TurboGears Resources there is a link Getting Started, which in fact does not link to the getting started Doc but links further down the same page (where you can find the link to the Getting Started doc). I know this is minor but I think that it is a little confusing to click on this first link and not go to the Getting Started doc (maybe only because I know it is there somewhere). Should this first link be called something like Where to Start or First Steps with TurboGears or something like that to avoid confusion? Anyway no big deal :-) Thanks Mark

[TurboGears] Possible Quick Fix For The 20 Min Wiki Tutorial
Just starting to get into TurboGears, and so far I am really enjoying it. Initially I could not complete the last AJAX section as adding tg_format=json to my pagelist page did nothing. I ended up tracking down the problem (I think I'm still new to this) to the dev.cfg file: # Allow every exposed function to be called as json, # tg.allow_json = False Changing this to tg.allow_json = True allowed me to spit out JSON output as described in the tutorial. Not sure if this is the correct way to solve the problem. Perhaps add a line in the tutorial to check the config file for this setting? Or if there is something else that has to be done add that (unless I'm blind and missed it).
