Hi,  
How can I use Ajax.Updater to send parameters from HTML - param1 and  
param2 the values of which are not in a form as such using  
Ajax.Updater in a manner such that on the server side, I use the  
model’s update\_attributes method.

new Ajax.Updater(  
‘#{options[:update\_html\_id]}’,  
‘#{options[:update\_url]}’+id,  
{asynchronous:true, evalScripts:true,  
parameters:‘authenticity\_token=’ +  
encodeURIComponent(‘Hl7TS7DG2dM0zmGAO09HMU8rKTNJwto37APahAPK9vA=’) }  
)

How can I modify the Updater above to generate the data below so that  
I can use model.udate\_attributes(params[:some\_model])

{ “authenticity\_token”=\>“Hl7TS7DG2dM0zmGAO09HMU8rKTNJwto37APahAPK9vA=”,  
“some\_model”=\>{“param1”=\>“value1”,  
“param2”=\>“value2”},  
“id”=\>“100”}
