#108 named_scope
May 19, 2008 | 11 minutes | Active Record, Rails 2.1
The named_scope method in Rails 2.1 makes performing finds on models very elegant and convenient. See how in this episode.
Note: there's a lot more to the named_scope method which I didn't cover, please see the links below for additional info.
models/product.rb
class Product < ActiveRecord::Base belongs_to :category named_scope :cheap, :conditions => { :price => 0..5 } named_scope :recent, lambda { |*args| {:conditions => ["released_at > ?", (args.first || 2.weeks.ago)]} } named_scope :visible, :include => :category, :conditions => { 'categories.hidden' => false } end
