Rails 3 change default english numbers to arabic numbers

Question

I want to change the default numbers from english to arabic when the user switches to the arabic interface.

13 => ١٣

89 => ٨٩

What is the best way to tackle this problem?

Answer 1

I add in helper module

ARABIC_NUMBERS = %w(٠ ١ ٢ ٣ ٤ ٥ ٦ ٧ ٨ ٩)
def ta numbers
  numbers = numbers.to_s if numbers.is_a? Integer
  results = numbers.chars.map { |char| ARABIC_NUMBERS[char.to_i] }.join
end

Answer 2

Check this code : https://github.com/gdotdesign/rails-arabic-convert/blob/master/app/helpers/convert_helper.rb.

It's a helper to convert a english number to an arabic number.

Answer 3

I came up with this quick solution. I added the following function in the ApplicationHelper

def tn(num)
  num.to_s.split(//).map{|r|t("n"+r)}.join
end

Then added translations for each number from 0 to 9 in the config/locals/ar.yml with the format below:

n1: "١"
n2: "٢"
n3: "٣"
.
.
.

Now we can call the new numeric translation function by tn(13) which will output ١٣ in arabic localization
