Can't access to elements of a hash after getting them from a csv

Question

I have a cvs and I want to access the values. If I do this:

    require 'csv'   
    CSV.foreach(filename, headers: true) do |row|
      new_row = row.to_hash
      puts "#{new_row}"
    end

This is the result -> {"user_id"=>"111", "sport"=>"aaa"}

But if I do this nothing gets printed

    require 'csv'   
    CSV.foreach(filename, headers: true) do |row|
      new_row = row.to_hash
      puts "#{new_row["user_id"]}"
    end

Why is this? How can I get the info?

Answer 1

Try using a symbol to find the key instead of a string

require 'csv'   
  CSV.foreach(filename, headers: true) do |row|
  new_row = row.to_hash
  puts new_row[:user_id]
end
