map.connect '*path', :controller => "pages", :action => "show"

In Rails, try() lets you call methods on an object without having to worry about the possibility of that object being nil and thus raising an exception
user_details = User.find(id).try(:user_details).try(:first_name)
#no need to worry if user_details is nill

# ActiveAdmin already includes the necessary jquery in active_admin/base,
# so just add this to javascripts/active_admin.js after //= require active_admin/base

# Serialize and Sort

# model_name - you guessed it, the name of the model we are calling sort on.
# This is the actual variable name, no need to change it.
