How do a call a "sibling" validator?

Question

This seems like it should be really easy, but I can't figure out how to do it

I am working on a feature that (in short) allows this view here (http://www.agileventures.org/projects) to have images associated with project descriptions. This is achieved by the user submitting a url* to an image in the project create/edit view. I need to validate the image url in a number of ways, which are done at this point ...except for validating it as indeed being a URL.

In the last version, this value was verified from [app/models/project.rb] as

validates :image_url, uri: true, :allow_blank => true

because of my other validations, I need to move this functionality to [lib/validators/image_url.rb]. There is a 'sibling' validator [lib/validators/uri_validator]. I cannot, for the life of me, figure out how to call it.

The codebase is here: https://github.com/sidhene/WebsiteOne/tree/image_url Help?

In this case I would say you should use validate :image_url, uri: true apart from calling your own validator (ImageUrlValidator) in project.rb as Saravanan suggested. If you are getting any errors when running your specs, plz post that error messages here and we can review them.
