AutoScope Plugin: automatic scopes for your needs
March 28th, 2007
Well, in relation to my Useful #with_scope technique post, here’s a plugin that implements that idea. This code is used on a production system. It works perfectly for my needs at the moment.
AutoScope
Automatically create scoped access methods on your ActiveRecord models.
Examples
Declare your scopes within your ActiveRecord::Base subclasses.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
class Contact < ActiveRecord::Base auto_scope \ :old => {:find => {:conditions => ["born_on < ?", 30.years.ago]}}, :young => {:find => {:conditions => ["born_on > ?", 1.year.ago]}} end class Testimonial < ActiveRecord::Base auto_scope \ :approved => { :find => {:conditions => ["approved_at < ?", proc {Time.now}]}, :create => {:approved_at => proc {Time.now}}}, :unapproved => { :find => {:conditions => "approved_at IS NULL"}, :create => {:approved_at => nil}} end |
1 2 3 4 |
Testimonial.approved.count Testimonial.unapproved.create!(params[:testimonial]) @young_contacts = Contact.young @contacts = Contact.old.find(:all, :conditions => ["name LIKE ?", params[:name]]) |
