Convert User input to integer

Question

So I have a form where users can input a price. I\'m trying to make a before_validation that normalizes the data, clipping the $ if the user puts it.

before_val         


        

Answer 1

I would define a virtual attribute and do my manipulation there allowing you to format and modify both the getter and setter at will:

class Model < ActiveRecord::Base

  def foo_price=(price)
    self.price = price... #=> Mods to string here
  end

  def foo_price
    "$#{price}"
  end

You also might want to note that:

"$50.00".gsub(/\D/, '').to_i #=> 5000
