Rails - Aug 2009 - text_field_with_auto_complete

I feel I''m on a constant Yak Shave
(http://projects.csail.mit.edu/gsb/old-archive/gsb-archive/gsb2000-02-11.html)

I am playing with Auto Complete''s, due to some excellent tutorials on
railscast.com I have been making progress although hit a small stumbling
block which hope you can solve.

So I am auto completing from my Country model, which has 2 attributes
''name'' and ''code''

If I just wanted the ''name'' attribute to be returned then this
would
suffice in my returns js

<%= auto_complete_result @countries, :country %>

However what I actually want is ''Country [code]'' e.g
''Great Britain [ GB
]''

However I don''t seem to be able to get this to work - in my Country
model I have added something like this.

def code_and_country
    "#{name} [ #{code} ]"
  end

  def code_and_country=(code_and_name)
    if m = code_and_name.match(/^([^\[]+)\[\s(\w{2})\s\]/)
      code = m[2]
      name = m[1]
    end
  end

so had hoped that I could use

<%= auto_complete_result @countries, :code_and_country %> - but I think
I am getting muddled up with methods and attributes.

So could someone be able to guide me on the correct way of doing it,
e.g. making code_and_country a fully fledged ''attribute'' of
Country or
somehow modifying the auto_complete_result helper to do the right thing?


Thanks for your help!

Sorry made a typo its

<%= auto_complete_result @countries, :name %>

not

<%= auto_complete_result @countries, :country %>

as :country is not valid!

To answer my own question - it seems text_field_with_auto_complete takes 
a array of hashes, so returning

@countries = Country.search(params[:search]).map{|a| {''code''
=>
a.code_and_country}}

<%= auto_complete_result(@countries, ''code'') %>
