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.

IMPLEMENTATION :

“BEFORE”

@album.album_photos.photos

“AFTER”
@album.photos
