Answer 1

Here you go.

in Movie model:

class Movie < ActiveRecord::Base
  has_many :connects
  has_many :actors, :through => :connects
end

in Actor model:

class Actor < ActiveRecord::Base
  has_many :connects
  has_many :movies, :through => :connects
end

in Connect model:

class Connect < ActiveRecord::Base
  belongs_to :movie
  belongs_to :actor
end
