Seems to work ok when running in the server but I get ArgumentError when using it in the console.

[HenryHaller]

I'm using this gem on a model called show and it seems to work normally in the server. But when I run Show.where(title: 'asdf') in the console I get ArgumentError: Unknown validator: 'UrlValidator' . I'm using validate_url-1.0.2 and Rails 5.2. Any advice?

I think it depends on your application code. Works well in my rails 5.2 applications

I'm getting this exception in app and tests in my rails 6.1/ruby 2.7 app. Will update if I figure out why...

Problem goes away for me with older validates_url helper.

Just installed and also have this error in console and server. Rails 6.1, no unusual code, no legacy code

using

      validates :attribute, url: { allow_blank: true, no_local: true }

Also seems to interfere with rails loading mechanisms. My enums are complaining that they are already defined after reloading the page
