URL Validator
URL validator makes possible check URI with different charset like: www.詹姆斯.com . For each setted variable to check, it generates the dynamic method called variable_normalized
, which return internationalized format of URI. For exmaple www.詹姆斯.com => www.xn--8ws00zhy3a.com
. This gem is using addressable gem for internationalizing and beyond regexp for checking valid URI. See in spec kind of valid/invalid URI.
Installation
Include the gem in your Gemfile:
gem "url_validator", "~> 0.0.3"
Or as a plugin:
rails plugin install git://github.com/zdenal/url_validator
Usage
In your class:
class User
attr_accessor :website
validates_url :website
end
Then somewhere in code:
@user.website = 'www.詹姆斯.com'
@user2.website = 'website.com'
@user.website_normalized # => www.xn--8ws00zhy3a.com
@user2.website_normalized # => website.com
@user.valid? # => true
@user2.valid? # => true
@user.website # => http://www.詹姆斯.com
@user2.website # => http://website.com
Url validator automaticly prefill scheme 'http://' (by schemes options - see below) if is missing in URI.
Options
-
:allow_blank => false/true
default = false. The same princip like in others validations. -
:allow_nil => false/true
> default = false. The same princip like in others validations. -
:message => 'Some custom message'
default is: "is not a valid URL". A custom error message. -
:schemes => ['http', 'https',...]
default = ['http', 'https']. Array of URI schemes to validate against. If checked URI missing scheme, then the first scheme of this array is chosen for prefill URI. -
:prefferred_scheme => 'ftp://'
default is the first item fromschemes
array. If setted, then the validator prefill the checked URI with this scheme if missing some scheme. -
:if/:unless => .....
the same like in others validations.
If preffered scheme is 'ftp://' and URI is with some scheme http://website.com, then after valid is URI http://website.com.
If preffered scheme is 'ftp://' and URI is without some scheme website.com, then after valid is URI ftp://website.com.
For constriction URI schemes, use option :scheme => ['ftp']
, then http://website.com will not valid and website.com will valid and prefilled to ftp://website.com.
