ProcessMethodBinding
by vicky 19 May '04

19 May '04

Hi, I made a change in the class ProcessMethodBinding but I do not want to change directly the code in processors.py. I want my class to be under another name ( MyProcessMethodBinding) in another file and to adapt it in nevow with compy.registerAdapter. My new class has to be to call up instead of ProcessMethodBinding. I've been searching for awhile and I didn't find out how to make. Thank you Vicky

Problem with Nevow changes
by Alex Levy 17 May '04

17 May '04

It seems like a couple things have broken (or, at the least, stopped behaving as they used to) since the freeform-patterned branch got merged back into trunk. For one, rend.Page.renderString() raises tracebacks. Ew. Second, something I haven't been able to figure out the cause of, method bindings that are part of a TypedInterface aren't being rendered with the proper values filled in. I've attached an example of what I mean; if you run this script with 'twistd -ony' using Nevow before the merge, the web form gets rendered with the appropriate values included. But after the merge, the forms appear blank. What gives? Oh, and if you run this with python instead of twistd, you'll see the traceback that rend.Page.renderString() is raising. Added bonus. :P -- Alex Levy WWW: http://mesozoic.geecs.org/ "Never let your sense of morals prevent you from doing what is right." -- Salvor Hardin, Isaac Asimov's _Foundation_

formless
by vicky 14 May '04

I saw that the structure and layout of the forms can be completely controlled with the new formless. I want to know if we can get examples for it and in which way it can be controlled. vicky

[PATCH] basic authentication and delimiter support for web.client
by Bryan Larsen 11 May '04

11 May '04

This patch adds two things to web.client: 1) support for basic authentication. (but not digest authentication). 2) allow the delimiter to be changed from '\r\n' to '\n'. Because of bugs in browsers, all servers send '\r\n' instead of the technically legal '\n'. But that's a pain for nph-sh scripts, so here's a quick hack to change the delimiter. To be legal, HttpClient should handle both '\n' and '\r\n' simultaneously, but LineReceiver does not provide this facility, so I'm using this hack instead. Bryan

Warning: Before you update Nevow. Major merge completed!
by Donovan Preston 07 May '04

07 May '04

Before you update Nevow to the latest version of trunk, make sure you have a few minutes to work around any potential roughness. The development which was happening on the freeform-patterened branch was merged tonight. All in all, it seems to be fairly backwards compatible. *You should clean out your old pyc files*. Otherwise, nevow will have problems starting up because it will import the old nevow/formless.pyc module instead of the new top-level formless package. If you were doing anything fancy with formless, such as subclassing Configurable or implementing your own Typed subclass, you will need to make some minor tweaks. The Configurable baseclass is now in the formless.configurable module, and the Typed.coerce signature is now coerce(self, data, configurable) instead of coerce(self, data). This merge almost completely rewrites the formless code from the ground up. The code is much more straightforward and better tested. formless.webform.renderForms() can now be provided with pattern nodes to influence the rendering of the forms. The structure and layout of the forms can be completely controlled. This merge also significantly simplifies how Nevow goes about the rendering process, reducing the previous flatten, strflatten _flatten, render, and other incomprehensible driver functions with a simpler set of driver functions, contained in the nevow.flat package. You probably won't care about this unless you would like to try to read the nevow code and understand how it works. If you encounter any other problems with this update, please let us know on the mailing list or on the #twisted.web channel. Thanks! dp

Re: [Twisted-Python] t.p.http handling of multipart/form-data
by stephen＠thorne.id.au 06 May '04

Yes! This is Fantastic! Keep working! Make sure you're on the twisted-web list, which is more appropriate for takling about web based technologies. Jump on irc and talk to dreid or fzzzy or myself (jerub) about where things are at with the new-web rewrite. Stephen. On Thu, 06 May 2004 17:57:13 -0400, "Stephen C.

I just did an svn update of the latest Nevow tonight, and I've got some brokeness. It seems that site-packages/nevow/compy.py is trying to import the following: from nevow.util import qual, namedAny however, I can't find these methods in util.py; am I doing something stupid? -- Duncan M.

rendering sub-Pages in nevow (probable bug)
by Federico Di Gregorio 04 May '04

04 May '04

Hi *, I am using nevow 0.1 so if this has been fixed/is a know problem just redirect me to the right resource. Apparently it is possible to serve a Page instance from a render_XXX method if it is implemented as a rend.stan docFactory but not if it tries to load a template from disk (rend.htmlfile). i.e., the following code (add some imports, etc.) works: class Foo(rend.Page): docFactory = rend.htmlfile('foo.html') def render_content(self, context, data): return context.tag.clear()[Bar()] class Bar(rend.Page): docFactory = rend.stan(T.p["Some content"]) but if Bar is implemented as follows, a "maximum recursion depth exceeded" error is raised (the function that gets called a zillion times is renderer._strflatten): class Bar(rend.Page): docFactory = rend.htmlfile('bar.html') I am trying to fix this, but I still don't know very well what happens under the hood during the rendering process, so hints are very apreciated. :) thanks, federico -- Federico Di Gregorio http://people.initd.org/fog Debian GNU/Linux Developer fog(a)debian.org INIT.D Developer fog(a)initd.org We are all dust, Saqi, so play the lute We are all wind, Saqi, so bring wine. -- Omar Khayam
