Not only does it work, but we are trying to move towards that being the suggested style, as it generally has superior error-handling characteristics. It would be really nice to get issues with it fixed, and even if this isn't a real problem, document it as a possible "gotcha" so people do not feel uneasy about taking this approach. So.. got a unit test? :)

How to insert an Athena event handler using Stan?
by kgi 01 Nov '06

01 Nov '06

Hi all. I've got some LiveElements in an Athena page to which I want to attach event handlers. Their XHTML is stan-based. What I've got right now (which works) is something like this, which I've understood is the Right Way to do it if you're explicitly using inline Javascript: _js = ( "Nevow.Athena.Widget.get(this).keyPressed(this, event); " + "return false;" ) docFactory = loaders.stan ( T.div ( render = T.directive ( 'liveElement' ), ) [ "Blah Text Label", T.input ( type = "text", _class = "sw-input", onkeyup = _js, ), T.div ( _class = "sw-output" ) [ "Blah More Text" ], ] ) There are messages in the mailing list (for example, from JP on October 11th 2006) recommending that one should use the athena:handler feature, like this: <textarea> <athena:handler event="onkeypress" handler="keyPressed" /> </textarea> However, if one has stan-based rather than file-based XHTML, it's neither documented nor obvious how this should be done. I've managed to get this far: from nevow import stan ... _athena = stan.Proto ( 'athena:handler event="onkeypress" handler="keyPressed"' ) ... T.input ( type = "text", _class = "sw-input" ) [ _athena ] This serialises OK, but it doesn't work, because the node doesn't get rewritten; that is, the generated XHTML contains the athena:handler node verbatim. Now, rewriteEventHandlerNodes() in Nevow/nevow/athena.py (around line 962) seems to traverse the tree looking for athena:handler nodes and replacing them with "Nevow.Athena.Widget.handleEvent()" Javascript, so I presume that the node I'm creating fails to get identified as an athena:handler node because I'm creating it incorrectly. What is the correct way to create such a node such that it gets picked up by rewriteEventHandlerNodes()? Regards, Ricky

> Hi, > I have many problems with nodes "id" attributes; using loaders.xmlstr all id names will be converted to "athena:X-nameid", but using loaders.stan they will be converted to "athena:X-athena:X-nameid" It seems to be a LiveFragment issue; I have switched to LiveElement, and now that's all ok. I'm speaking about the trunk code, so I think the examples will be update in the future. Alessandro PS: I'testing the rev 9594; the head revision has some problem istalling the "js" directory and I have to copy it manually under /usr/lib/python2.4/etc.. ------------------------------------------------------ Riascolta i tuoi 33 e 45 giri con un bellissimo Giradischi Retrò, tecnologia HI-FI, collegamento PC e design anni '60 ! http://click.libero.it/dmail3

nevow athena: node id issue (bug?)
by aleuser＠inwind.it 20 Oct '06

20 Oct '06

Hi, I have many problems with nodes "id" attributes; using loaders.xmlstr all id names will be converted to "athena:X-nameid", but using loaders.stan they will be converted to "athena:X-athena:X-nameid" Client side "self.nodeById('nameid')" function is not able to locate the correct node if the node has been created with loaders.stan. Do you think is a bug? For example, you can modify the examples/athenademo/widgets.py modifying the Clock class: from nevow import tags as T docFactory = loaders.stan(T.div(id="test_id")[' this is a test ']) and the source html will be ... <div id="athenaid:1-athenaid:1-test_id"> this is a test </div></div ... <div id="athenaid:2-athenaid:2-test_id"> this is a test </div></div Alessandro ------------------------------------------------------ Riascolta i tuoi 33 e 45 giri con un bellissimo Giradischi Retrò, tecnologia HI-FI, collegamento PC e design anni '60 ! http://click.libero.it/dmail3

Don't use the context?
by Jonathan Lange 18 Oct '06

18 Oct '06

Hello, "DON'T USE THE CONTEXT" has been in the #twisted.web topic for some time. I've heard that the context is being removed from Nevow. * Why is the context being removed? * What should I use instead of the context to get at ctx.tag? * How does nevow:data stuff work in a world without context? * nevow-rendering.txt should be updated. It currently recommends that people use the context. cheers, jml

Crypto with py2exe
by Paul Tonning 18 Oct '06

18 Oct '06

I have a twisted app using Crypto (twisted.internet.ssl) Works great, but when I use py2exe to create a standalone I get NameError: Can't find file for module Crypto All of the Ciphers compile to .pyd files and are in the dist directory but there is no Crypto.pyd file. Any ideas or possible work arounds? Thanks in advance. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
