Ajax routes in Rails 3

In my Rails 2.3 application, the following routes were working properly

map.ajax 'ajax', :controller => 'widgetresponse_controller'   , :action => 'getWidgetJson'

When I migrated to Rails 3,

I tried a number of new routes, to get this working but none of them worked.

1.

match 'ajax' => 'widgetresponse#getWidgetJson', :as =>开发者_如何学JAVA; :ajax

2.

match 'ajax' => 'widgetresponse_controller#getWidgetJson', :as => :ajax

3.

get 'widgetresponse/getWidgetJson', :as => :ajax

4.

get 'widgetresponse/getWidgetJson'

Its a very basic question to ask, but I don't know what I am doing wrong.

You could try this:

match "/widgetresponse/getWidgetJson/:id" => "widgetresponse#getWidgetJson"

One thing that may have happened before is that things were falling through to the default route which was removed in Ruby on Rails 3 (good idea).

I found this guide:

really helpful with lot of yummy new rails 3 options.
