import from CSV into Ruby array, with 1st field as hash key, then lookup a field's value given header row

Question

Maybe somebody can help me.

Starting with a CSV file like so:

Ticker,\"Price\",\"Market Cap\"
ZUMZ,30.00,933.90
XTEX,16.02,811.57
AAC,9.83,80.02
         


        

Answer 1

Not as 1-liner-ie but this was more clear to me.

csv_headers = CSV.parse(STDIN.gets)
csv = CSV.new(STDIN)

kick_list = []
csv.each_with_index do |row, i|
  row_hash = {}
  row.each_with_index do |field, j|
    row_hash[csv_headers[0][j]] = field
  end
  kick_list << row_hash
end
