'Include' in rails query

For getting a datum from 2 tables, I have used include as follows,

Admin:

belongs_to :user

There was a condition that i have to sort names of admins, where the names of admins will be in user table.

Hence,

Admin.find(:all, :include=>"user", :order => "users.name")


I felt this easy than sqls, & interesting
