I mean, I want to build a form as in formbuilder example or similar, but render it in many pages like: def render_myForm(self,ctx,data): return FormBuilder() as a piece of different pages but with the same behavior, depending (the behavior) only from the url request. So if I build a form that add a named 'box' in my page column, the form is the same for all my pages. -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Bisogno di liquidità?

formless problem

I wrote this simple app, where the RootPage has only a single child, named \'form\'. This child \'FormBuilder\' is directly taken from formbuilder.py in the example directory of last svn Nevow. The child is correctly rendered but when I try to add an element to the form, it doesn\'t appear (the formbuilder example work well if a try the Nevow example). Any help? ############################ ### Root Page ############################ from nevow import loaders from nevow import rend from nevow import tags as T from nevow.stan import directive from formbuilder import FormBuilder class RootPage(rend.Page): addSlash = True docFactory = loaders.stan( T.html [ T.body [ T.a ( href=\'form\' ) [ \'form page\' ] ] ] ) def child_form(self, ctx): return FormBuilder() ############################ -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Con la Pietra Naturale puoi grigliare carne, pesce e verdura direttamente in tavola!

I can't imagine why else this would fail. dp

Please review: make nevow vhosts log to separate files
by Tommi Virtanen 04 Jan '05

04 Jan '05

nevow/sandbox/tv/logvhost/ contains code to make vhosts log to separate files. It is currently written by subclassing nevow classes, but after I get a nod or two, will be rewritten as a proper branch. I'd like some guidance on how to proceed, how you want to solve things. I'll just cut-n-paste the README here: Adds a new interface, 'IVirtualHost', which is remembered in context whenever a virtual host is activated (even the default counts as activation). The value is the root resource of the active virtual host. If the root resource of the vhost has the attribute 'vhostName', that is taken to be the canonical name of the vhost, and logs are written with this name into the directory containing the file logPath. The API may be ugly. The monkeypatching needed to make it works may be ugly. But nevow _needs_ to be able to log virtual hosts to separate files.

Sorry resending after a small edit. sent to wrong list by msitake. I copied some code from an existing site of mine to a new machine and boom.... does not work anymore :) the code is based on the guard example... : It seems the code that fails is: def render_sessionId(self, context, data): sess = inevow.ISession(context) return context.tag[sess.uid] The complete trace follows.

[PATCH] Pass context to static.File processors
by Alex Levy 03 Jan '05

03 Jan '05

Attached are patches for twisted.web2 and nevow which will allow File processors to take three arguments (path, context, registry). It keeps backwards-compatibility for processors that take only (path, registry), mainly because they're a pain to update ;) I can't find any places where the registry is actually used, but I've left it in to make backwards-compatibilty easier. So, anyone's thoughts?
