Subject: Re: ActiveSupport undercore behaviour

I changed as follows and it works for the first nest level for the 
moment:

def format_hash_key(hash)
  Hash[hash.map {|k, v| [ActiveSupport::Inflector.underscore(k.to_s), v] 
}]
end

arr = []
TECHS.each_value do |array_values|
  array_values.each do |hash|
    arr << format_hash_key(hash)
  end
end
puts arr

Output:


{"assigned_name"=>"P1", "export_price"=>"USD", "id"=>"1", 
"delivery"=>"Y", "registered_members"=>[{"Name"=>"Admin", "Id"=>"3", 
"AvailablePosts"=>[{"Seat"=>"2", "Colour"=>18}, {"Seat"=>"3", 
"Colour"=>19}, {"Seat"=>"4", "Colour"=>181}, {"Seat"=>"5", 
"Colour"=>183}]}]}

Is there any elegant way to call the same method for other nested levels 
(values) ?

Thank you.
