Colander: How to list attributes? Mixins or inheritance?
Hi all, about Colander I have 2 questions: [1] given a colander schema like class Principal(MappingSchema): is_enabled = SchemaNode(Bool() , title = 'Enabled?' , foo = 'bar' ) How can I build a list of the defined fields which are class attributes and tell their kwargs? (I'd like to use Colander to define more general data dictionaries and want to read those definitions under different circumstances.) [2] If many schemas have several attributes in common, is it possible to define them in a separate schema and use that as a mix-in? Or must the common schema be inherited from? [a] Mixin class MyMixin(object): frobotz = SchemaNode(Bool() , title = 'FroBotz?' , baz = 'qux' ) class MySchema(MappingSchema, MyMixin): ... [b] Inheritance class MyMixin(MappingSchema): frobotz = SchemaNode(Bool() , title = 'FroBotz?' , baz = 'qux' ) class MySchema(MyMixin): ... Thanks for your help.

Re: deform: template cache and i18n

Now I only have a limited number of locales to support, so I was thinking about initializing template loaders for these locales at application start. But in this case, the cache decorator would have to take the translate attribute into account as well and not only the template filename. Try upgrading to Chameleon 2.x.

Re: deform: template cache and i18n
ok. i got chameleon 2.3 to work. but I still think I have to keep locale specific TeplateLoaders around to make caching work, because the registry key for a template does still not take locale into account, thus may retrieve a template with the wrong translator.

Extracting translation strings for templates using include macros
Since i18n seems to be the topic of the day, I would really appreciate help with this: I have a master template to contain headers and so forth, with various pages 'inheriting'. So, master has: tal metal:define-slot=mainMain page content in div/tal and the pages will do: tal metal:use-macro=master div metal:fill-slot=main Pretty standard stuff. However, I can't manage to extract translation strings from the various templates. If I add the full html header: html xmlns=http://www.w3.org/1999/xhtml; xmlns:tal= http://xml.zope.org/namespaces/tal; xmlns:i18n= http://xml.zope.org/namespaces/i18n; i18n:domain=myapplication it will work, but only if I also remove the macro code. Otherwise, the extractor (lingua-xml) ignores the strings - presumably on the grounds that the xml is not valid by itself. Could somebody advise me as to the best way to do this? I've experimented with variations on the theme of: http://chameleon.repoze.org/docs/latest/i18n.html#relation-with-metal-processingbut none seem to get me anywhere.

Unicode value
I have a form that I put a unicode character in one of the fields.

The value in request.params shows u'Test Unicod\xc3\xa9' -- I think this should be u'Test Unicod\xe9' if it was properly decoded to utf-8.

Re: Pyramid, Mod_WSGI and Webfaction help needed
Hi Awais, I use webfaction and I've always created a custom app (listening on port). I know it's not the most helpful answer, but you might consider setting up the app to listen on a certain port, configuring paster to run on that port, and then running: $ bin/paster serve --daemon production.ini start As for the other issues, I'm not clear on how you're transferring the code to the server. Unless you are using the server as your development environment, it might help to build the application on your computer, package it into an egg, and install it on the server with easy_install. You can always use the --install-dir=/some/other/directory option with easy_install if you really want it to be placed somewhere other than the site-packages directory of your virtualenv, although personally I think that is the best place. If you release revisions later on you can deploy a new egg with a new version number and not have to worry about keeping all the folders and subfolders of an entire application in sync in two different spots. Lastly,if you want uploaded files sent somewhere else you'd need to install the application in a different directory or specify a different path for uploading. For production applications on webfaction I run a separate static application to serve images/css/js and then mount it at myappurl/static/, to prevent requests for those files from having to go through the application. Anyway, I hope this gives you a better starting point, but I realize I haven't fully answered your questions. Maybe someone more familiar with mod_wsgi can jump in.

When I create a new app as shown in step 6 in webfaction: $ cd ~/modwsgi/env $ bin/paster create -t pyramid_starter myapp Every time I copy 'myapp' development files from my local machine to the server via ftp I have to do: $ ../bin/python setup.py install for the app on the server to update.

Re: deform: template cache and i18n
Yes, that's what I'm doing now. Right now it's sort of tied to the TemplateLoader, though - at least the way deform uses Chameleon. So what I do is keep the zpt renderers around and assign to renderer.loader.kwargs['translate'] per request - not exactly a nice API to do that.

Pyramid, authentication and userid

Moreover, I can pass to pyramid.security.remember not string but object (sqlalchemy model for example) and everything is working just fine (stored in the session).
