Rails Associations for current_user

Question

I a while ago i read this article: http://pivotallabs.com/users/nick/blog/articles/275-advanced-proxy-usage-part-i which is talking about AR proxy etc..

The author pointed what is my issue now.

This example will describe it.

class Gallery
  has_many :images, :class_name => 'Image'
  has_many :my_images, :class_name => 'Image' #, :conditions => "images.user_id == current_user.id" # FIX THIS
end

and here

class Image
  belongs_to :user
  belongs_to :gallery
end

Notice: I use PostgreSQL

So when you access my all images with a gallery: Gallery.first.includes(:my_images)

If i want to return all images: Gallery.first.includes(:images)

So now how to pass the current user to the conditions in the has_many ?

Edit

User
  has_many :images
  has_many :galleries, through: :images

Answer 1

If i understand well, you want to get something like :

current_user.galleries.first.images

If so, you would just need to create a has_many association between User and Gallery through a third model, possibly named UserGallery.
