Question

I am using Ruby on Rails 3.2.9 and I would like to validate that the first char of a name (a String) is not a number (Integer). I am trying to use the following code:

class User < ActiveRecord::Base
  validates_each :name do |record, attr, value|
    record.errors.add(attr, 'cannot begin with a number') if ... # the first char is a number
  end
end

How can I make that?

Answer 1

record.errors.add(attr, 'cannot begin with a number') if value =~ /^[0-9].*/

that will match any string whose first character is a number
