UriFormatValidator

Gem Version Build Status Code Climate Test Coverage

Introduction

This gem provides URI field validator for Rails' Active Model.

UriFormatValidator requires Active Model 4+. It is tested against MRI 2.2.2+, JRuby, and Rubinius in their recent versions.

Getting started

Add this line to your application’s Gemfile:

gem 'uri_format_validator'

Then install by executing bundle install. You may now define validations in your models, like that:

class User < ActiveRecord::Base
  validates :home_site_url, uri: true
end

For Rails 6, you may need to specify the namespace like that:

class User < ActiveRecord::Base
  validates :home_site_url, 'uri_format_validator/validators/uri': true,
end

For your convenience, an old-fashioned validation helper is also provided:

class User < ActiveRecord::Base
  validates_uri_format_of :home_site_url
end

Validation options

URI component constraints

You can specify constraints on URI components: scheme, authority, path, query, and fragment.

validates :home_site_url, uri: { scheme: /https?/ }
validates :home_site_url, uri: { scheme: %w[ssh telnet] }

validates :home_site_url, uri: { authority: /\.example\./ }
validates :home_site_url, uri: { authority: %w[example.com example.test] }

# require path component (`/` is not enough)
validates :home_site_url, uri: { path: true }
# disallow presence of path component
validates :home_site_url, uri: { path: false }
# match path against regular expression
validates :home_site_url, uri: { path: /regexp/ }

# require query component
validates :home_site_url, uri: { query: true }
# disallow presence of query component
validates :home_site_url, uri: { query: false }

# require fragment component
validates :home_site_url, uri: { fragment: true }
# disallow presence of fragment component
validates :home_site_url, uri: { fragment: false }

When scheme option is unspecified, only http and https are allowed.

Relative URIs

By default, only absolute URIs are valid. Specify authority: false option to allow relative and disallow absolute URLs:

validates :home_site_url, uri: { authority: false }

Reachable URLs

With retrievable options, you can ensure that URL indeed points to some resource. A HTTP HEAD request will be performed to that URL, and it must result with 2xx status code. Otherwise, given value is considered invalid.

validates :home_site_url, uri: { retrievable: true }

Error messages

You can also override the default error message:

validates :my_url_attribute, uri: true, message: 'is not a valid URL'

Alternatively, you can provide your own localization string for errors.messages.invalid_uri key.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
