ruby - Append a a hash to a CSV in Ruby 1.8

Question

How to append to a array of hashes into CSV in Ruby 1.8. There is FasterCSV for Ruby 1.9 but how do I do in 1.8?

This is what I have tried. hasharray is an array which contains elements which are hashes.

CSV.open("data.csv", "wb") { |csv|
  hasharray.each{ |oput|
    oput.to_a.each {|elem| csv << elem}
  }
}

This way puts all the data in the CSV but it puts them one below another instead of side-by-side.

迭代哈希时，您希望在块中使用两个参数，一个用于键，另一个用于值。考虑：

hasharray.each { |k,v| puts "#{k},#{v}" }
