jquery - Specifying name of rails partial to render using a variable -

is possible in rails 3.0 render partial name of partial stored in variable?

i attempting similar to:

<%= escape_javascript(raw render :partial => @partial_name, :locals => { :value => @value} )%> 

updated more details

in application have set of models using multi-table inheritance, example lets have base model 'cupcake' , variants such 'awesomecupcake' , 'alrightcupcake'.

each of these models have own custom partial displaying information , follow naming scheme: '_awesome_cupcake' , '_alright_cupcake'.

on page have links each type of cupcake in want controller accept parameter , dynamically derive partial render. following works wanted if (in new.js.erb file) replace '@partial_name' such 'awesome_cupcake'.

here little more information how components laid out:

application.js

$('#set_cupcake').click(function () {    $.getscript('/cupcakes/new.js?cupcake_type=awesome'); }); 

cupcakes_controller.rb

def new    cupcake_type = "#{params[:cupcake_type].capitalize}cupcake"     if object.const_defined? cupcake_type      @cupcake = cupcake_type.constantize.new      @partial_name = "#{params[:cupcake_type]}_cupcake"    end end 

views/cupcakes/new.js.erb

$('#cupcakes')   .append("<%= escape_javascript(raw render :partial => @partial_name, :locals => { :cupcake => @cupcake } ) %>") 

of course. make sure @partial_variable string of name (such "header" , work fine.
