hey, i was wondering how to do this i have these models phones and location class Phone < ActiveRecord::Base belongs_to :location end class Location < ActiveRecord::Base has_many :phones end when i wanna find all locations, that the model also find the phones for each location Now i get the locations, need only 1 location X, then get all phones for location X. These are 2 database callings i wanna reduce this to 1. (perhaps on model level) can anyone help me?

If you know beforehand that when you load a location you have to access all its phones, load it with :include option Location.find :first, :conditions => "...", :include => [:phone] Kent.

Remember a location has many phones. If you wanted to include the location when retrieving a number of phones you would ":include => :location". Because a phone has only 1 location. -Brian
