Validates URL

This gem adds the capability of validating URLs to ActiveRecord and ActiveModel.


Add this to your Gemfile:

gem "validate_url"

Or install it yourself:

sudo gem install validate_url


With ActiveRecord

class Pony < ActiveRecord::Base
  # standard validation
  validates :homepage, url: true

  # with allow_nil
  validates :homepage, url: { allow_nil: true }

  # with allow_blank
  validates :homepage, url: { allow_blank: true }

  # without local hostnames
  validates :homepage, url: { no_local: true }

  # with custom schemes
  validates :homepage, url: { schemes: ['https'] }

  # with public suffix database
  validates :homepage, url: { public_suffix: true }

  # with Postgres array of urls, described [here](
  validates :homepage, url: { accept_array: true }

With ActiveModel

class Unicorn
  include ActiveModel::Validations

  attr_accessor :homepage

  # with legacy syntax (the syntax above works also)
  validates_url :homepage, allow_blank: true

With RSpec

Require the matcher in spec_helper.rb or rails_helper.rb:

require 'validate_url/rspec_matcher'

In your spec:

RSpec.describe Unicorn
  it { validate_url_of(:homepage) }


The default error message is not a valid URL. You can pass the message: "my custom error" option to your validation to define your own, custom message.
