is there a way to always eagerly load an associated object so that you don''t have to put :include into every finder? class Product <ActiveRecord::Base belongs_to :user #always load user when product is loaded end Product.find(1).user.login #1 query since user was loaded with the product, same as if i used :include but I don''t want to have to specify it everywhere. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

i''m not aware of any config to do this automatically... perhaps
someone more experienced knows a way.
another way is to make a method in your model:
class Product <ActiveRecord::Base
belongs_to :user
def self.find_eager(id)
self.find(id, :include => :user)
end
end
note you''d have to do a little more work to get it to work with all
options to find(), like :all, :conditions, :order etc...

I believe this would be a good fit for with_scope http://api.rubyonrails.org/classes/ActiveRecord/Base.html#M001024 class Product <ActiveRecord::Base belongs_to :user def self.find_eager(*args) with_scope( :find => { :include => [:user] } ) do find(*args) end end end You could also alias_method_chain find on the Product class and wrap find in a with_scope there instead. That way could be neater. Cheers Daniel --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

YMMV class Product <ActiveRecord::Base belongs_to :user class << self def find_with_user_scope( *args ) with_scope( :find => { :include => :user } ) do find( *args ) end end alias_method_chain :find, :user_scope end end This way whenever you call Product.find it will be scoped to include the user. If you don''t want to include the user then you can use Product.find_without_user_scope( *args ) HTH Daniel --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
