[Python-modules-team] Bug#575313: @expose("json") does not work anymore

[Enrico Zini]

Package: python-turbogears2
Version: 2.0.3-2
Severity: normal

Hello,

again, thanks for maintaining TurboGears2.

It looks like "@expose("json")" stopped working. How to reproduce:

 1. paster quickstart foo
 2. cd foo
 2. $EDITOR foo/controllers/root.py 
 3. add this method:

    @expose("json")
    def foo(self):
        return dict(r="foo")

 4. paster setup-app development.ini
 5. paster serve development.ini

Visit http://localhost:8080/foo.

I get this DeprecationWarning on stderr:

   /usr/lib/pymodules/python2.5/tg/controllers.py:182: DeprecationWarning: pylons.buffet is deprecated and will be removed in Pylons 1.0 entirely. The new render functions should be used instead.
     response = self._render_response(controller, output)
 
And this wonderfully surreal error:

TypeError: No object (name: buffet) has been registered for this thread

(with a very long stack trace involving a large amount of functions,
modules, wrappers, frameworks, middlewares, factories and whathaveyou
that I swear I've never heard before).


Ciao,

Enrico
