This is a cheatsheet for samples how to create objects dynamically

objectCreationByConfigString.coffee

# Prerequisite there is a modelName.coffee class file in the corresponding folder
createObjectSample1 : (modelName) ->
   new ( require "models/"+modelName)()

# This method only takes the className, supposing that require class loading took place
createObjectSample2: (strClass) ->
   # Let's cache the Views
   if window.cache[strClass] != undefined
      log.debug("Approuter.newInstance: Reusing cached Instance "+strClass)
      return window.cache[strClass]
   else  
      log.debug("Approuter.newInstance: Creating new Object "+strClass)
      # Arguments will be converted into an array, i.e. it means strClass
      args = Array.prototype.slice.call arguments, 1 
      clsClass = eval strClass
      F = () -> return clsClass.apply this, args
      F.prototype = clsClass.prototype
      window.cache[strClass] = new F()
      return window.cache[strClass]
