ValidateZipcode

Adds ZipCode / PostalCode validation support to Rails (ActiveModel) and test it in a simple way.

Any other country's postal code that not on the list of country identification will validate without errors.

Installation

Add this line to your application's Gemfile:

gem 'validate_zipcode'

And then execute:

$ bundle

Or install it yourself as:

$ gem install validate_zipcode

Usage

Just use as any other validator passing the country:

ValidateZipcode expects the model has an attribute called country to contain the country identification.

This Gem use as country identification the codes supplied by the ISO 3166-2 (International Organization for Standardization).

class Address < ActiveRecord::Base
  validates :zipcode, zipcode: {country: "US"}
end

Error Message

If you need to localize the error message, just add this to your I18n locale file:

errors:
  messages:
    this_zip_code_is_invalid: "This zip code is invalid"

You can provide your own message using :message option.

validates :zipcode, zipcode: {country: "US", message: "new error message"}
