Subject: Re: Mering an array of hashes

I would do it like this:

a1 = [{:name=>"File1.rar", 
:id=>"a3d80425a51a3a4cb2d7a3201439ef6cc3af5874"},
      {:name=>"File2.avi", 
:id=>"58a658047ccb7333eb812da02dca9d84c1db2b41"},
      {:name=>"File3.avi", 
:id=>"944f6a7c50a4a5cff0c28cb0f9158b16580b0310"}]
a2 = [{:name=>"File2.avi", :other_attributes =>"stuff"},
      {:name=>"File1.rar", :other_attributes=>"stuff"},
      {:name=>"File3.avi", :other_attributes=>"stuff"}]


a3 = Array.new
a1.each do |entry1|
  a2.each do |entry2|
    if entry1[:name].eql? entry2[:name]
      a3.push(entry1.merge(entry2))
      break
    end
  end
end
p a3
