Append a value in a hash object (in Ruby), using an already existing key?
How can I append a value in a Hash object using a key that already has a value. So for example if I have >> my_hash = Hash.new >> my_hash[:my_key] = "Value1" # then append a value, lets say "Value2" to my hash, using that same key "my_key" # so that it can be >> my_hash[:my_key] => ["Value1", "Value2"] I know its easy to write my own method, but I just wanted to know if there is a built in method.
