class Release < ActiveRecord::Base
  has_many :release_sites
  has_many :sites, :through => :release_sites
end

  has_many :release_sites
  has_many :releases, :through => :release_sites

# så kan du lave sådan noget her:

@site.releases # => array af releases
@release.sites # => array af sites

@release.release_sites # => array af release sites
@release.release_sites.first.queued?

@site.release_sites # => array af release sites
@site.release_sites.first.queued?
