It's rough, but I think you're asking how to use a Rails' model efficiently. Is that correct?
Do you have an example of a model you've created we can look at?

ya , its correct for example i am fetching photo object using model like @album.album_photos.photos so internally it query on three table but i can directly fetch photos on query on photo table? so which is efficient? if data cm from model it cached or not? explain brief.
Maybe you can use rails relational mapping.
example : ....................................
class Album < ActiveRecord has_many :album_photos, :dependent => true has_many :photos, :through => :album_photos
....................................
class Photo < ActiveRecord has_many :album_photos, :dependent => true has_many :albums, :through => :album_photos
....................................
class AlbumPhoto < ActiveRecord belongs_to :album belongs_to :photo
....................................
I hope this Trough Association matter can help your problem.
