I've got the following associations: class Photo < AR::Base has_many :slides has_many :albums, :through => :slides
# this has an attachment_fu attachment which creates a thumbnail image for each uploaded photo. end class Album < AR::Base has_many :slides has_many :photos, :through => :slides end class Slide < AR::Base belongs_to :photo belongs_to :album end In my Photos#index action I render all thumbnails and list the albums that the photos belong to. I'm using attachment_fu, the parent image is the one with the slide and album association, the thumbnail image does not have that association. The index action is hitting the database to load all albums that belong to a photo, how can I cut that down to one query for eager loading? Currently I'm doing: Photo.find(:all, :include => :parent, :conditions ['thumbnail = ?', 'small']) but I can't figure out how to eager-load the albums, through slides, based on the parent photo (since the thumbnail doesn't have any associated slides or albums.)
