I’m new to RJS and am trying to figure out how @params are passed/  
available with my hierarchy.

# views/test/person.rhtml

\<%= link\_to\_remote(‘GO’, {:url =\> “/test/show?name=walker&age=77”})%\>

# controllers/test\_controller.rb

class TestController \< ApplicationController  
def update\_person  
render :update do |page|  
page.show\_helper  
end  
end  
end

# helpers/application\_helper.rb

module ApplicationHelper  
def show\_helper(params)  
page.replace\_html ‘name’, :partial =\> ‘name’  
page.replace\_html ‘age’, :partial =\> ‘age’  
end  
end

# views/test/\_age.rhtml

# views/test/\_name.rhtml

Ideally, I would like the @params in views/test/person.rhtml to be  
available in their respective partials as such:  
\<%= @params[:age] %\>  
and  
\<%= @params[:name] %\>

Thanks in advance for any help you may be able to offer
