Passing the variables from from jquery to rails controller

I need to pass a variable which is captured from client side via jquery to controller, so that it can be used in the server side. After googling a bit, I found that we can pass it via an Ajax call.

routes.rb

get "mymethod?Id=", :to => "sample#mymethod"

j1.js

$(function(){

var test = 1;

$(.btn).click(function(){

  $.ajax({
           url: '/mymethod?Id='+ test,
           success: function(data) {
                 }
         });
    });

});

sample_controller.rb

def mymethod
 session[:Id] = params["Id"];
end

When I try to use session[:Id], it is always nil.

Any ideas,

Thanks

If you want to make a GET request in jquery you'd be better off doing:

$.ajax({
    url: '/mymethod',
    success: function(data){ // anything },
    data: { Id: test }
});

Because it urlencode and format the parameters correctly for you.

In rails, remove the reference to the Id in routes.rb and just use the params dictionary in your controller to access the variable Id (info here: http://rails.nuvvo.com/lesson/6371-action-controller-parameters)
