A link to the api docs may get you started: http://api.rubyonrails.org/classes/ActiveResource/Base.html#M000827 Also look at the code generated with scaffold. I simply added a json format.
def index @sites = Site.find(:all)
respond_to do |format| format.html # index.html.erb format.xml { render :xml => @sites.to_xml }
format.json { render :json => @sites.to_json } end end
These are called with the URL: http://somesite.org/index.html http://somesite.org/index.xml http://somesite.org/index.json
