I'm trying to set up a custom renderer (namely for rendering protobufs),
but I can't figure out how to set it up. I've tried the various examples on
how to do it, but I never get them to work. The error I get is:
>
> TemplateNotFound: Template "protobuf" not found
I've written a render function, called render_pbuf, which I'm trying to set
in the app_cfg.py file like so (only showing relevant parts of the file):
> from coreapi.custom_extensions import render_pbuf
> base_config.renderers.append('json')
> base_config.default_renderer = 'genshi'
> base_config.renderers.append('genshi')
> base_config.render_functions['protobuf'] = render_pbuf
Then, I'm decorating a method in my root controller like this:
@expose('protobuf', content_type='application/x-protobuf')
> def test(self):
> return {
> 'foo': 'bar',
> 'ba': 'zinga'
> }
And a longer stack trace of the error:
File '/.../python2.7/site-packages/tg/controllers/dispatcher.py', line 124
> in _perform_call
> r = self._call(func, params, remainder=remainder)
> File '/.../python2.7/site-packages/tg/controllers/decoratedcontroller.py',
> line 145 in _call
> response = self._render_response(controller, output)

> File 'build/bdist.macosx-10.7-x86_64/egg/genshi/template/loader.py', line
> 246 in load
> TemplateNotFound: Template "protobuf" not found
Worth noting is that the code in the render_pbuf function never runs, I've
added 10/0 as the first line just to make it crash if it does run, but it
never does, so the problem lies elsewhere.
Does anyone have any idea on what I'm doing wrong?
