ok, rails 3 new developer here.
I want my jquery to be able to get a json object from the rails 3 application for projects. Here is my controller.
def yo
:formats=>[:html]
That says the server is thinking that html is being requested. Try adding a .json to your path (and possible route) and that will force the format. TO make that would would need a route something like this:
map.your_projects '/projects/yourprojects.:format',
:controller => 'projects',
:action => 'yourprojects'
Somehow, someway, the params[:format] should be "json" for this request so the format handlers can do the right thing.
