Better ruby syntax

Question

I'm fairly new to ruby and its rubyisms, I have a code similar to this one :

def my_method objects
  temp = []

  objects.each do |o|
    temp <<  {
      :text => o.text,
      :title => o.title
    }
  end

  return temp
end

Could you help me to write this better ? Or show me some sources to learn this kind of rubyisms plz ? I'm already doing the ruby koans lessons.

You could use map:

def my_method objects
  objects.map { |e| {text: e.text, title: e.title} }
end

About the resources: I strongly recommend reading Eloquent Ruby.

Edit

I used the Ruby 1.9.x hash syntax.

It may be good to indicate for beginners that the Hash syntax you are using is 1.9 only. – Sébastien Le Callonnec Mar 03 '12 at 10:40
