URLAttributes

A small and simple gem for validating URL attributes in your ActiveRecord models.

Installation

Add the gem to your Gemfile

gem 'url_attributes'

And run bundle install.

Usage

Add a string column to your ActiveRecord model which will contain a url, e.g. link, then call the class method url_attribute in your model like this:

class MyAwesomeModel < ActiveRecord::Base

  url_attribute :link

end

This does two things:

It adds a validation to link that
Before save, it strips trailing whitespace from the link and adds "http://" to the beginning if it (or "https://") is not already there.

If you want the logic to run somewhere other than before_save, pass a :before option with the name of another before_ callback:

class MyAwesomeModel < ActiveRecord::Base

  url_attribute :link, before: :validation

end

Matcher

The gem also comes with an RSpec matcher. You can use it like this:

describe MyAwesomeModel do

  it { is_expected.to have_url_attribute :link }

end
