Convert hash keys to lowercase — Ruby Beginner

Question

My table field names are lowercase and the field names I get from CSV files are camelcase. Is there anyway I can convert the keys of an array of hashes to lowercase?

Answer 1

You can use something like this:

CSV.foreach(file, :headers => true) do |row|
  new_hash = {}
  row.to_hash.each_pair do |k,v|
   new_hash.merge!({k.downcase => v}) 
  end

  Users.create!(new_hash)
end

I had no time to test it but, you can take idea of it.
Hope it will help
