Convert a csv file to array of hashes (just like SmarterCSV), useful when SmarterCSV throws wierd errors

csv_to_hash.rb

require 'csv'

def csv_to_array(file_location)
 csv = CSV::parse(File.open(file_location, 'r') {|f| f.read })
 fields = csv.shift
 fields = fields.map {|f| f.downcase.gsub(" ", "_").to_sym}
 csv.collect { |record| Hash[*fields.zip(record).flatten ] } 
end

test = csv_to_array('test.csv')
