Have a look at "has_many :through", that should do what you need.

Max,

thank you very much. I've tried the following,

  In release.rb (model),

   has_many :platforms, :through => :branches

  this results in an error, which asks to specify, :source also (I doubt this is because platform_id is not present in the branches table directly!)..

  neither :source => release nor :source => platforms works.

  I'm stuck here!
