validates :url => true also validates for presence

[keilmillerjr]

An error should not be thrown if the field is blank. This should be handled with :presence validator.

Thanks for reporting this @keilmillerjr.

Do you want to send a PR ?

Thanks again!

I've been investigating a bit the other validators' behaviors and it seems they all behave the same and will throw an error if the field is blank. Have you tried something like validates :url, url: true, unless: :blank?

If this still doesn't work, I'll reopen the issue.

Thanks a lot!

I am getting the same error.

Tried using unless: blank? but no luck.

FYI it doesn't work with unless: blank? but it works fine with allow_blank: true

So you can write:

validates :link_url, url: true, allow_blank: true

It works for me with Rails 4.0

A note or example of this on the readme would be helpful.

Done. Thanks !
