twisted on mac. twisted.web problems.
by aaron smith 11 Nov '07

Hey all. I can't figure out what exactly is going on with my python install. I've tried installing twisted on both mac leopard and tiger. It installs fine, but when I try to run a basic twisted.web http server. I get errors about the web module not existing. It seems like some load path issues. I've tried numerous different hacks on the load path just to get it at least loading. but to no avail. does anyone else have crazy problems like this? By default twisted was being installed here: /Library/Python/2.3/site-packages/twisted I've tried putting twisted in :/System/Library/Frameworks/Python.framework/Versions/2.3/Extras/lib/python/twisted I've also tried some things with the interpreter. $>python >>>import twisted Traceback (most recent call last): File "<stdin>", line 1, in ? File "twisted.py", line 1, in ? from twisted.web import http ImportError: No module named web >>> ----------------- $>python >>>import sys >>>sys.path = ["/Library/Python/2.3/site-packages/twisted"] >>>import twisted >>>import twisted.web Traceback (most recent call last): File "<stdin>", line 1, in ? ImportError: No module named web I'm really stuck. dah! Any ideas? Thanks

Re: [Twisted-web] Nevow Athena & Frames - Not any more....

The fragments should be > rendered into a div or some such area on the main page, not a frame. OK, thanks for the advice. Have redesigned to <div>s (LiveFragments) in one LivePage - - A "vertical" div, populated at page render time. Gets id="athena:1". - A "horizontal" div (gets id="athena:3"), for showing results from clicking a row in "athena:1". I can see nice flattened HTML in the log, by renderSynchronously(), but I have trouble finding the "athena:3" node, to display it. Here's what I've tried: - self.nodeById() in the callback triggered by the JS func that called Python. The HTML looks fine. The callback didn't seem to know about self.node, so I passed it as an arg. - however, in the 1st func, self.node.id = "athena:1" (from the click in the first div). - Nevow.Athena.NodeByAttribute(root, ...) which calls Divmod.Runtime.theRuntime.nodeByAttribute(selt, root, ...), which appears to do a tree search. Now the question is: How do I find "root"?? Presumably, it's one level above "athena:1", "athena:2", etc. I tried with "Divmod._location+Nevow.Athena.livepageID+'/jsmodule'", since that was the value of jsModuleRoot of class LivePage, but no luck. Sound like a newbie? Good guess :-) Hoping for some more patience........

Divmod Nevow 0.9.26
by Tristan Seligmann 10 Nov '07

I'm pleased to announce the release of Nevow 0.9.26. The last announced release was 0.9.18, and the changes since that version are listed below. 0.9.26 (2007-11-02): - url.URL.path now correctly escapes segments in the string it evaluates to. - inevow.IAthenaTransportable added, along with support for serialization of custom types for server-to-client Athena messages. - Global client-side behaviour is now customizable via a client PageWidget class. 0.9.25 (2007-10-16): - The Athena message queue implementation has been improved, fixing problems masked by bugs in Firebug/YSlow. 0.9.24 (2007-09-05): - ESC key no longer disconnects Athena connections. - Fixed a bug where URLs with quote characters will cause the Athena connection to be lost. - Fixed 'twistd athena-widget' to create a fresh widget instance for each hit. 0.9.23 (2007-08-01): - Fixed install script to include all JavaScript files. 0.9.22 (2007-07-06): - Mock DOM implementation for easier browser testing added. - JavaScript source files are now read using universal newlines mode. - athena.AutoJSPackage now excludes dotfiles. - url.URL now properly subclassable. - User-agent parsing added to Athena, to detect known-unsupported browsers. 0.9.21 (2007-06-06): - Debug logging messages from the reliable message delivery queue disabled. 0.9.20 (2007-05-24): - Athena now no longer holds more than one idle transport open to the browser. 0.9.19 (2007-04-27): - Changed the styling of the progressbar to work on IE6. - Athena.Widget.detach added, to allow widgets to cleanly be removed from a page. - Athena.Widget.callLater added, a wrapper around setTimeout and clearTimeout. - 'athena-widget' twistd command added, for starting a server which serves a single LiveFragment or LiveElement.

Nevow Athena & Frames
by Harald Blåtand 08 Nov '07

08 Nov '07

Hi, Athena seems like the coolest since the Russians invented the wheel :) With the Athena tutorial at divmod.org as a starting point, I'm trying to make a page with 2 frames. Both need to send/receive events to the server, plus they need to communicate with each other. Left frame will show a table of tablenames in a database. Clicking a tablename will cause data from this DB table to show up in the right frame. Clicking an item in the right frame will call a server method for further processing. As I understand it, both frames need to be fully-fledged LivePages, right? They can use the same JS file, only they must have different JS classes(?) Things work fine as long as only Left Frame is live, just causing data to show in Right Frame. When Right Frame also becomes a LivePage, it starts to behave funny: - Clicking an item in Left Frame - nothing happens. - Clicking same item again (not dblclick) - both events are seen by the server. So, something seems to be "sitting on" the first click, and when the 2nd one comes, both are sent. I must have made some redundant stuff here, but can't figure out what. Below are some code fragments. Grateful for any hints, and thanks for a great toolkit! -------------------------- Server: ------------------------------- class FrameSet(rend.Page): docFactory = loaders.stan( T.frameset(cols="50%, *")[ T.frame(name="left_pane", src="leftPane"), T.frame(name="right_pane", src="rightPane"), ] ) .... class LeftPane(athena.LivePage): addSlash = True docFactory = loaders.xmlfile('visPlan.html') def render_commElement(self, ctx, data): print '***LEFT COMM ELEMENT***' f = LeftCommElement() f.setFragmentParent(self) return ctx.tag[f] ... class RightPane(athena.LivePage): docFactory = loaders.stan( T.html[ T.head(render=T.directive('liveglue')), T.body[ T.div(id='firstDiv', render= T.directive('commElement')) ] ] ) def render_commElement(self, ctx, data): print '***RIGHT COMM ELEMENT***' f = RightCommElement() f.setFragmentParent(self) return ctx.tag[f] ... class LeftCommElement(athena.LiveElement): jsClass = u'VisPlan.LeftComm' docFactory = loaders.stan(T.div(render=T.directive('liveElement'))[ T.input(type="button", value="Show Clients", onclick=' Nevow.Athena.Widget.get(this).show_clients()'), ... class RightCommElement(athena.LiveElement): jsClass = u'VisPlan.RightComm' docFactory = loaders.stan(T.div(render=T.directive('liveElement'))) ... -------------------------- JS file: ------------------------------- // import Nevow.Athena VisPlan = {}; VisPlan.LeftComm = Nevow.Athena.Widget.subclass('VisPlan.LeftComm'); VisPlan.RightComm = Nevow.Athena.Widget.subclass('VisPlan.RightComm'); VisPlan.LeftComm.method( 'table_cell_clicked', function(self, arg) { self.callRemote('tableCellClicked', arg); }); VisPlan.RightComm.method( 'gif_clicked', function(self, arg) { self.callRemote('gifClicked', arg); });
