validates_uri_format_of

Rails plugin that provides a validates_uri_format_of method to ActiveRecord models. You can require or disallow certain components of a URI.

Just add the following line to your environment.rb:

config.gem 'validates_uri_format_of'

After installing the plugin, it's used like

class User < ActiveRecord::Base
  validates_uri_format_of :url,
                          :allow_nil    => true,
                          :require_fqdn => true
end

• :schemes – allowed URI schemes. Default: ['http','https']
• :require_scheme – Default: true
• :require_host – Default: true
• :require_path – Default: true
• :require_fqdn – enforce a fully qualified domain name? Default: nil
• :with_port – Default: nil
• :with_query – true requires a query string (e.g. '?query'), false does not allow a query string. Default: nil (no check)
• :with_fragment – true requires a fragment string (e.g. '#fragment'), false does not allow a fragment string. Default: nil (no check)
• :with_auth – true requires authentication info (e.g. 'http://user:pass@example.com/'), false does not allow a fragment string. Default: nil (no check)
• :on – Specifies when this validation is active (default is :save, other options :create, :update).
• :if – Specifies a method, proc or string to call to determine if the validation should occur (e.g. :if => :allow_validation, or :if => Proc.new { |user| user.signup_step > 2 }). The method, proc or string should return or evaluate to a true or false value.
• :unless – Specifies a method, proc or string to call to determine if the validation should not occur (e.g. :unless => :skip_validation, or :unless => Proc.new { |user| user.signup_step <= 2 }). The method, proc or string should return or evaluate to a true or false value.
