How to remove duplicates in a hash in Ruby on Rails?

Question

I have a hash like so:

[
  {
    :lname => \"Brown\",
    :email => \"james@intuit.com\",
    :fname => \"James\"
  },
  {
    :lname => nil,

In Ruby 1.9.2, Array#uniq will accept a block paramater which it will use when comparing your objects:

arrays.uniq { |h| h[:email] }
