FasterCSV：列到数组中— rails

Question

I'm trying to get fastercsv setup so that rather than parsing each row, it will place each column into an multi array.

CSV import file:
id, first name, last name, age
1, joe, smith, 11
2, jane, doe, 14

Save to array named people:
people[0][0] would equal id
people[2][1] would equal jane

This is what I currently have:

url = 'http://url.com/file.csv'
open(url) do |f|
  f.each_line do |line|
    FasterCSV.parse(line) do |row|
      row
    end
  end
end

Any help is appreciated.

Answer 1

Have you read the FasterCSV documentation?

If you did, you would know that the easiest way to do what you want is:

people = FasterCSV.read('http://url.com/file.csv')

Answer 2

Thanks EmFi, with your help I was able to come up with a solution.

This takes a remote url csv file and loads it into a multi-dimensional array, based on columns.

require 'rio'
require 'fastercsv'

url = 'http://remoteurl.com/file.csv'
people = FasterCSV.parse(rio(url).read)

Answer 3

您可以在FasterCSV上使用CsvMapper ，这是一个救生器
