by the way this is documented here http://trac.turbogears.org/ticket/1960 > Anyway, so I got rid of the ordinary template @expose decorator, > leaving only the @expose("json") and when I visit the URL with my > browser I do get a application/json type response, but it is empty.

I haven't tried to have two @expose on the same method but I'm pretty sure only using @expose('json') works fine, I have been using it in the alpha's and betas. What is your controller returning? it should still return a dict, is it returning an object type that isn't list/dict? maybe posting your controller will be a good idea. As a related note, I think that our final implementation for this will be to choose the template/render based on the URL, so for example project.json will return json while project.html will return html from your default html renderer, this new feature is here http://trac.turbogears.org/ticket/1473. > > Any help would be much appreciated. > > Cheers > Iain > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TurboGears" group.
